Filament materials for which the 3D printer is designed.

Most developed 3D printing technologies (see above) involve the use of more than one material, and these materials differ markedly in properties. Therefore, the choice of materials is limited not only by technology, but also by the capabilities of a specific printer, and this parameter cannot be neglected while choosing. Today, you can mainly find devices designed for such materials (in alphabetical order): ABS, ASA, BVOH, Carbon, CPE, Flex, HIPS, Nylon, PC, PETG, PLA, PP, PVA, SBS, TPE, Wood, photopolymer resin. A separate category is food 3D printers that allow you to create sculptures from chocolate, cream, etc.

Here is a description of the materials that have received the most distribution nowadays (both those mentioned above and some others):

— ABS. One of the most common types of thermoplastic nowadays; quite po...pular in 3D printing. At a low cost, ABS is very practical: completed products are durable, quite resistant to deformation and shock, insensitive to moisture and many aggressive liquids (alkalis, oils, a large amount of detergents); they also have a good temperature range of operation (on average of -40 to 90 °C). And for melting such plastic, relatively low temperatures are required. There are three main disadvantages of ABS. Firstly, it is sensitivity to direct sunlight and rapid deterioration in such conditions (although it all depends on the particular variety). Secondly, this material emits harmful fumes when heated — so it is advisable to use protective equipment during operation, or at least provide effective room ventilation . Thirdly, ABS tends to stick strongly to the printing table, which requires the use of various additional tricks — heating the table, using special thermal tape, etc. Also note that completed products made of this material have a rough surface, but this can be an advantage — depending on the situation.

— PLA. Another popular material for 3D printing, a direct competitor to ABS. One of the key advantages of PLA is its eco-friendliness: it is made from vegetable raw materials (mainly corn and sugar cane), is biodegradable and safe when heated. In addition, this type of thermoplastic has a lower melting point and practically does not stick to the printing table. On the other hand, the downside of the mentioned environmental friendliness is a limited service life: PLA plastic decays rather quickly (from several weeks to several years, depending on the variety). Other notable cons are the price (almost twice as high as ABS) and fragility (which makes printing somewhat more difficult — a strongly bent thread breaks easily). It is also worth keeping in mind that this type of plastic does not dissolve in acetone and requires other solvents.

— Photopolymer resin. A material used for printing using SLA and DLP technologies (see "Printing Technology"), as well as widely used in MJM printers, where it has almost replaced thermoplastics. The name is due to the fact that the initial state of such a material has a liquid consistency, and it solidifies (polymerizes) under the influence of intense lighting. Nowadays, there is a wide variety of photopolymer resins that differ in technological characteristics (viscosity, setting speed, sensitivity to light) and practical features (a solid photopolymer can have the properties of different materials). Anyway, using such materials for printing is very accurate, but photopolymers are much more expensive than thermoplastics.

— Nylon. Nylon has been used in 3D printing relatively not long ago, thats why it is less common than other popular thermoplastics. Compared to ABS, this material requires higher temperatures, emits more harmful substances, and when completed it tends to accumulate moisture and lose durability, which puts forward certain restrictions on use. On the other hand, nylon products are not as hard, that is in some cases becomes an advantage — particularly, in medical applications: splints and prostheses with a characteristic mesh structure can be printed of this material, combining lightness and durability.

And here is a detailed description of the rest, more rare materials:

— ASA. A weather-resistant material designed to remove the main con of ABS — sensitivity to environmental influences (primarily sunlight). The result is a fairly durable and rigid material, which at the same time is quite easy to print and does not lose its properties during prolonged exposure to the open air. ASA products are even suitable for automotive applications; another pros of this type of thermoplastic is very little shrinkage during cooling. Disadvantage of ASA filament is a higher cost rate than ABS.

— BVOH. An auxiliary water-soluble filament used for printing support structures with protrusions and overhangs, as well as moving mechanisms. BVOH is an acronym for Butenediol Vinyl Alcohol Copolymer. Flament has excellent interlayer adhesion and sinteres well with the material of the model itself, so that the supports do not peel off from the part during the 3D printing process. The optimal extrusion temperature for this plastic is in the range from 210 to 220 °C. The material easily dissolves in ordinary water - it can be used to create a strong base in areas where support is required, and to obtain a smooth surface without filament residue when used in printing with other types of plastic (PLA, ABS and PET).

— Carbon. A polymer-based printing material with the addition of carbon fiber, developed by Carbon Inc and given the same name. It is an excellent alternative to Nylon plastic, has high interlayer adhesion and low deformation shrinkage. Carbon also has high strength and temperature resistance. This material is used to create functional parts, prototypes, tools, mechanically loaded parts, housings for various devices, parts for repairing household appliances in a wide variety of industries (including automotive, medicine, etc.). Carbon plastic is suitable for almost all models of desktop 3D printers.

— CPE. CPE copolyester is a chemically resistant and relatively durable printing material characterized by high impact strength and temperature resistance. It usually includes polyethylene (PE) and polyester in varying proportions. CPE has good strength and flexibility, which makes it suitable for creating functional parts in various fields: prototyping, modeling, production of functional parts, etc. The recommended nozzle temperature for printing with CPE plastic should be between 230 and 260 °C. The temperature of the print bed can vary depending on the printer and nozzle size - it is often in the range of 70 to 85 °C.

— Flex. A type of thermoplastic based on polyurethane, the main feature is the flexibility and elasticity of completed products — hence the name. In terms of its properties, Flex is often compared with solid silicone: it is not afraid of impacts, is insensitive to oil, gasoline and many other aggressive liquids, wearproof and durable (except that the operating temperature for completed products of this type of plastic is in range up to 100 °C). This material is quite suitable for FDM printing (see "Printing Technology"), however, it requires special settings; therefore, to use Flex-plastic, it is best to choose printers with compatibility is directly stated.

— HIPS. Material used as an secondary — to create supports of the overhung parts. HIPS compatibility can mean that the printer has more than one extruder: one nozzle feeds the base material in such cases, the other feeds the support material. However, there are also models for one nozzle that are compatible with this type of plastic — the printing of supports and the main product is carried out alternately. However, once printing is complete, the HIPS supports can be removed with a special solvent. Regarding this, HIPS is somewhat more difficult to use than the similar PVA (see below), which dissolves in water; on the other hand, ordinary citric acid can be used as a solvent for HIPS, and moisture resistance simplifies the safekeeping of consumables. Also note that this material is recommended to be used only in combination with ABS: the last one has similar requirements for printing mode and is not damaged by solvents for HIPS.

— PC. Polycarbonate plastic (PolyCarbonate) from the group of amorphous thermoplastics with a high degree of transparency. PC is one of the popular materials used to create transparent or translucent parts (lenses, protective helmets for cycling and motorsports, lighting products, etc.). Polycarbonate has excellent impact resistance and resistance to high temperatures, does not react with many chemicals, and is a good insulator of electricity. PC plastic has a high melting point (from 150 °C), and its fluidity is achieved at temperatures of about 280 - 300 °C.

— PETG. There are also designations as PET, PETT. These are all varieties of the same material: PET is the original polyethylene, PETG is supplemented with glycol to reduce fragility and make printing easier (which makes it the most spread variety in 3D printers), and PETT is transparent and noticeably harder than PETG. Anyway, in terms of their main features, these types of thermoplastics are something in between the popular ABS and PLA: they are easier to use than the first type, and more plastic than the second one. The main disadvantages of PETG are the tendency to accumulate moisture (regarding this PETG is similar to nylon) and less scratch resistant than the ABS.

— PP. Polypropylene is very popular in various plastic products, but has not gained much popularity in 3D printing, mainly due to significant shrinkage and difficulties in ensuring the desired quality of the layers connection. In addition, PP does not tolerate low temperatures well. At the same time, this material also has advantages: it resists abrasion well, has good durability, and is also safe to manufacture and chemically inert.

— PVA. A material known to many by PVA stationery glue. In 3D printing, it is used as a secondary one, similar to the HIPS described above: supports and other auxiliary elements are printed from PVA, which must be removed of the completed product. At the same time, this material has two important advantages over HIPS. Firstly, PVA dissolves in water, which eliminates the need to look for special solvents. Secondly, it can be used not only with ABS, but also with other thermoplastics. The main disadvantage of this material is associated, again, with solubility in water: PVA must be safekeeped in the most dry conditions, since even high humidity can worsen its properties.

— SBS. A relatively new type of thermoplastic, which the main feature is transparency: it is possible to create products from SBS that are practically indistinguishable from glass (including painted in different colours). In addition, this material is more flexible and elastic than ABS, which is an advantage both in finished products and in the printing process: the filament entering the extruder will not break even with a strong bend or significant stretch. The durability of SBS is quite high, and due to its chemical inertness, it is suitable even for tableware. The main drawbacks of this material are the rather high printing temperature and low adhesion between layers, which makes the process more difficult.

- TPE. Thermoplastic elastomer, combining the properties of plastic and rubber in one bottle. TPE has high elasticity and flexibility, which allows this material to be used to create flexible and resilient parts that can deform under pressure and return to their original shape. It is used for the manufacture of seals and gaskets, elastic parts of toys, shoes, covers for mobile gadgets, automobile parts (including interior elements and tires). TPE is characterized by anti-allergenic properties, scratch resistance, and good adhesive properties.

— Wood. A type of PLA plastic (see above), which contains fine wood dust. Due to this, products made of such material are very similar on touch to wood, and outwardly they can be almost indistinguishable. Another interesting feature is that adjusting the temperature of the extruder, you can change the shade of the material: increased heating leads to a darkening of the wood contained in the composition. The main properties of Wood are similar to PLA, but the amount of sawdust may be different; the higher it is, the closer the completed product is to wood, but the lower leads to elasticity and durability. Actually, one of the disadvantages of this material is its relatively low durability. It is also worth considering that Wood is poorly compatible with narrow nozzles (they tend to clog with wood particles).

— PC. Polycarbonate is one of the world's most popular plastics and one of the most durable and reliable materials used in 3D printing. In addition to mechanical strength, it is resistant to heat. On the other hand, the printing temperature must also be quite high, and it must be carefully controlled due to significant shrinkage; and due to the hygroscopicity of the material during operation, it is also necessary to maintain low humidity. All this significantly complicates printing, so polycarbonate is used very rarely in this format.

— PC/ABS. A blend of two plastics designed to make polycarbonate more suitable for 3D printing while maintaining its core values. Products of this material are durable, rigid, resistant to shock and heat; and the printing procedure, although quite complicated, is still much simpler than with a pure PC.

– Carbon (Carbon Fibre). A composite material based on carbon fibers supplemented with a thermoplastic filler — usually nylon, although other types of 3D plastic (ABS, PLA, etc.) also can be used. The specific properties of such a material depend on the composition of the filler and the percentage of fibers, but there are also common features. On the one hand, such a material is quite expensive, but at the same time it is more durable and reliable than the corresponding plastic without carbon fibre; many varieties of carbon are successfully used for full-featured parts operating under high loads. In addition, carbon fibre gives the material elasticity. On the other hand, printing requires special nozzles of high hardness — stainless steel or with a ruby tip; softer materials wear off quickly due to the abrasive properties of carbon fibre.

— TPU. The material of the class of so-called plastic elastomers based on polyurethane. It differs from other materials of the same class in higher rigidity, durability and resistance to low temperatures. At the same time, TPU is quite flexible and elastic compared to thermoplastics in general, and not just to polyurethane plastic elastomers.

— PEEK. Thermoplastic semi-crystalline type, characterized by high durability, resistance to chemical and thermal influences, as well as abrasion. Due to these properties, PEEK can be used in parts that suffer significant loads — moving parts of mechanical transmissions and even parts of automobile engines. On the other hand, infusibility requires high printing temperatures and a closed heat chamber, and the filament itself is expensive. Because of this, this type of thermoplastic is practically not used in household 3D printers, and its main application is the professional sphere.

— HDPE. A kind of polyethylene, the so-called low pressure polyethylene (high density). A very popular material among modern plastics, used in plastic bottles, many types of food packaging, etc.; however, it is not popular in 3D printing. This is due to a number of difficulties in layer-by-layer application: HDPE solidifies very quickly, and that is why you need to print at high speed — otherwise adhesion between layers may be insufficient. In addition, this type of polyethylene is highly susceptible to shrinkage, so printing requires uniform heating of the entire model — and this requires a closed operating chamber and a heated platform. On the other hand, printing consumables are very cheap, they can be obtained by simple recycling of household waste (the plastic bottles, etc).

— CoPET. A kind of polyethylene, slightly different in production technology from conventional PET. According to the authors, the higher reliability, durability and resistance to environmental influences are achieved than ABS, and even more so PLA. At the same time, CoPET is inexpensive and easy to use, as it has a fairly low melting point and excellent adhesion between layers. On the other hand, the operating temperatures of completed products are also low — less than 60 °C. In addition, this material is difficult to post-process and does not lend itself to regular solvents, and usable solvents are prohibited from free sale in many countries.

— POM. Industrial grade filament featuring high durability, low friction and cold resistance. Thanks to this, even gears and other similar parts (including those subjected to significant mechanical loads), as well as bearing elements, can be printed from POM. On the other hand, the printing process itself is quite complex, requiring a closed chamber with careful temperature control, as the material is highly shrinkable. In addition, the POM part is difficult to fix on the printing table due to low adhesion: high-quality glue is required, which is not easy to find.

— Rubber. A thermoplastic that resembles rubber in its properties and is close to the Flex type plastic described above. However, in comparison with the "Flex" Rubber is even softer and more elastic; at the same time, it is durable and resists damage well (although, for the same reason, it is difficult to process). One of the examples of typical use of this material is the printing of wheels; in addition, it is very resistant to solvents and effectively resists even rather aggressive environment, where less resistant materials are not suitable. The univocal disadvantages of this type of plastic include, first of all, the high printing temperature.

File format for 3D models that the printer can handle.

Projects of 3D models are created using special programs (CAD — computer-aided design systems), while such programs can use different file formats, often incompatible with each other. This information can be useful both for selecting CAD for a specific printer model, and for assessing whether ready-made projects are suitable for printing on the selected model.

Among the most common file extensions nowadays (in alphabetical order) are — .3ds, .amf, .ctl, .dae, .fbx, .gcode, .obj, .slc, .stl, .ply, .vrml, .zrp.

Software for building models which the printer is optimally compatible with. The software used for 3D printing includes both CAD (automatic design systems for creating models) and slicers (software that break a three-dimensional model into separate layers, preparing it for printing). Therefore, this paragraph often indicates a whole list of software products.

Note that the degree of optimization in this case may be different: some models are compatible only with the claimed programs, but many printers are able to work with third-party CAD systems. However, it is best to choose software directly claimed by the manufacturer: this will maximize the capabilities of the printer and minimize the chance of failures and “inconsistencies” during operation.

The smallest thickness of a single layer of material that can be applied with a printer.

In photopolymer devices of SLA and DLP formats (see "Print Technology") the meaning of this parameter is simple: it is the smallest height of a one pass cycle of the working platform. The smaller this height, the better detailing can be achieved on the device; however, in such models, this height is usually small — most often less than 50 µm. But in devices based on FDM/FFF and similar technologies using nozzles, there are also higher rates — 51 – 100 µm and even more. Here it is worth noting the fact that a small minimum layer thickness allows efficient use of small nozzles and achieves better detail. On the other hand, increasing detailing reduces productivity, and to compensate this fact, it is necessary to increase the print speed by increasing power (both heating and blowing), which, in turn, affects the cost. Therefore, choosing one should proceed from real needs: for objects with relatively low detail, there is no need to look for a printer with a small layer thickness.

It is worth noting that in FDM/FFF printers, the optimal layer thickness depends on the nozzle diameter (see below) and the specifics of printing — for example, for a “in one line” perimeter without filling, you can use the minimum layer thickness, while for filling it is not recommended. Det...ailed recommendations on the optimal layer thickness for different situations can be found in special guides.

The heating temperature provided by the extruder in an FDM/FFF or PJP printer (see Printing Technology) .

Compatibility with this or that printed material directly depends on this parameter. For example, for PLA plastic, temperature range 180 – 230 °C is required, for ABS it will require 220 – 250 °C, and for polycarbonate — at least 270 °C. The temperature definitely should not be too low — otherwise the material simply cannot melt normally. But the margin in most cases is quite acceptable — for example, many PLA-compatible models operate at temperatures of about 250 °C, or even 280 °C.

Thus, a higher operating temperature enhances the printer's capabilities and its compatibility with various types of thermoplastics. On the other hand, the more the material is heated, the worse it cools down; to ensure sufficient solidification efficiency, one must either reduce the printing speed (which increases the time required) or increase the blowing intensity (which affects the cost). Well, anyway, while choosing, you should focus primarily on filaments, which compatibility is directly indicated in the specs.

Additional features of the printer.

The list of the most popular features in modern 3D printers includes, in particular, a heated bed, a closed chamber, object scanning, a built-in camera, an LCD display (including touch), filament sensor, as well as resuming print function. Here is a more detailed description of these features:

— Heated bed. The availability of heating in the printing platform — the surface that is used as a support for the model to be built. This feature is found mainly in FDM/FFF printers (see "Printing Technology") and similar. The heated table ensures smooth and uniform cooling of the material, reducing the chance of deformations in completed models; this is especially important using materials with significant shrinkage. Also note that this feature is especially effective when combined with a closed print chamber (see below).

— Closed chamber. Operating area with a closed design. The specific designof such a chamber can be different — from a platform fenced on four sides to a sealed compartment where you can even create a vacuum for some specific printing methods. These nuances should be clarified separately. Anyway, the closed chamber protects the pr...inted product from dust, moisture and other contaminants; but the more specific meaning of this feature may be different — depending on the printing technology (see above). So, in FFF/FDM printers and similar devices, the closed design allows to achieve more uniform cooling of the workpiece and avoids deformation due to material shrinkage. And almost all SLA and DLP units have such a design — even in the simplest models of this category, the operating area is covered at least with a light filter that protects the user from bright light.

— Object scanning. Built-in 3D scanner that allows you to create “digital masks” of various objects. The printer can recreate then a copy of the scanned item, based on that masks. This function actually turns the device into a three-dimensional copier: the user does not need to build a model in a CAD programme, it is enough to have a sample for copying. However, if necessary, the digital image can be edited — usually, the scanner allows you to transfer the received data to the same CAD programs.

— Built-in camera. Own digital camera installed directly into the printer and aimed at the operating area. Designed to capture the workflow; most often it allows you to shoot both photos and videos, but it's ok to clarify the specific shooting capabilities separately. Regarding the use of cameras, it is worth noting that printers with such equipment usually also have Wi-Fi modules and/or LAN network connectivity (see "Data Transfer"). This allows you to transfer the captured video over a local network or even over the Internet (these details, again, should be clarified for each model), and further use of the footage depends primarily on the user's desire. One of the most popular ways to use this is remote control of printing: if you have a camera, you can monitor the process without having to go to the printer once again. In addition, the data from the camera (live or recorded) can be used as a demonstration, as a visual aid for training/instruction, etc.

— Resume printing. A feature that allows you to continue the printing process after it has been stopped. It is useful primarily in cases where the printer is used at strictly defined hours — for example, during working hours; it can also come in handy if the printer is turned off due to a power failure. The second option is fairly obvious; and regarding the first, we should remind that 3D printing is a rather continuous process, and the creation of even a small product takes hours. Because of this, situations often arise when a work day (or other similar period of time) is not enough to complete the work. In such situations, the resume printing feature is useful: the printer can be paused for the duration of the absence, and to resume the process with returning to the printer. However, it should be noted that operating with some filaments, interruptions in work are undesirable; so if you plan to use this function, it's ok to clarify its compatibility with the preferred filament.

— Filament sensor. Sensor for controlling the supply of plastic filament during the printing process. As a rule, such a sensor is installed on the extruder (print head). If the filament suddenly runs out or its supply is interrupted, the sensor will prevent the print from failing due to lack of material - if it detects a lack of filament, it transmits a signal to stop the print so that the user can add filament and resume the process.

Data transfer methods provided in the 3D printer design. We are talking primarily about data relating to the model being printed (from which the printer directly prints), in some cases also about setting up the device and other ways of interacting with it; For more details, see individual list items.

As for specific options, in addition to the traditional communication to a PC via USB or USB type C, modern printers may provide data transfer methods such as a card reader, its own USB port, a network communication via LAN, as well as a wireless communication via Wi-Fi. Here are the features of each of these options:

- Card reader. The printer has its own memory card slot. Most often designed to work with popular SD cards; however, even such media have several varieties, so it would not hurt to check the range of supported cards separately. In any case, the main purpose of this function is direct printing: by installing a card with a recorded project file in the printer, you can make a model without even connecting the device to a computer. There may be other ways to use the card reader - for example, copying materials from a model scanner to external media (see “Functions and capabilities”). Note that this function is convenient mainly for exchanging dat...a with a laptop - a slot for memory cards is available in almost any modern laptop.

- USB. Own USB connector on the printer body. It is used similarly to the card reader described above - for working with external media, in this case “flash drives” and other similar devices. The methods for using the USB port are also similar - mainly direct printing, but other options are also possible (copying data from a scanner, updating firmware, etc.).

— USB type C. Availability of a USB type C port in the interface communication shelf of the device. Such connectors are smaller in size compared to classic USB, and they also have a convenient double-sided design that allows you to connect the plug to either side. USB type C is supposed to be used to connect a 3D printer to a computer or mobile gadgets for managing and transferring printed files. At the same time, this connector can be used to connect external storage media.

- Wi-Fi. A wireless communication module that can be used both to connect the printer to local networks and for direct communication with tablets, laptops and other gadgets. Specific capabilities should be clarified separately, but here we note that a network communication allows you to use the printer as a common device for all computers on the local network and even access it from the Internet (although the latter may require specific settings). At the same time, Wi-Fi is a more convenient alternative to a wired LAN (see below), as it allows you to do without laying wires. As for direct communication with another gadget, this option is less common. It usually provides the ability to send projects for printing and access to basic settings; and to use such control, you may need to install a special application.

— Connection to PC (USB). Connecting to the USB port of a PC or laptop is the most popular way to directly connect a 3D printer to similar devices. The vast majority of modern computers are equipped with ports of this type, and even connectors of the outdated version of USB 2.0, not to mention newer standards, are enough to work with a printer. The communication itself can be used both to send print jobs and to control operating parameters - and it is through a PC/laptop that detailed settings that are not accessible through the screen on the printer itself are usually implemented. In addition, if necessary, you can share access to the unit via a computer via a local network or the Internet - even if the printer itself does not have a LAN connector or a Wi-Fi module. This is much more difficult to organize and not as convenient as using a network model with a direct communication to the local area, but it eliminates the need to overpay for additional connectivity options in the printer itself.

— Connection to PC (LAN). Connection to external devices via LAN - a standard connector for wired communication to computer networks. Actually, such a communication is intended mainly for using the printer as a network device - when access to printing and settings can be obtained from different computers on a local network, or even via the Internet. LAN is less convenient to connect than Wi-Fi, as it requires cabling, but this communication is more reliable and does not suffer from the presence of a large number of wireless devices nearby. In addition, the cable can be useful if the Wi-Fi router or access point does not reach the printer location.
Note that the standard use of LAN involves connecting to a network router, but a direct communication to a computer is also possible. The second option allows you to use this connector similarly to the USB described above - that is, only for one computer; but if this computer is connected to a local network and/or the Internet, you can also configure network access to the printer.

The printer has its own screen. The specific functionality of such a screen can be different - from the simplest indicator for several characters and service symbols to a full-fledged color matrix capable of displaying inscriptions, drawings, etc.; These nuances should be clarified separately. However, in any case, this feature provides additional ease of management: various service information can be displayed on the screen to help the user set up printing parameters and control the process.
We would like to emphasize that touch displays are not included in this category; they are indicated as a separate function. But the screen size directly affects the comfort when working with the device.

There are also models with a touch screen, similar to those used in smartphones and tablets. Such a display is a full-fledged control tool, and it is more convenient and functional than more traditional options such as keypads: you can display a wide variety of control elements (buttons, sliders, lists, etc.) on the screen, selecting the optimal set of these elements for your needs. specific situation. In addition, the screen itself usually has a color matrix with a fairly high resolution, which makes it possible to display a wide variety of service data - even drawings and diagrams. Thanks to all this, most printer control functions can be performed through such a display; some models with such equipment are able to work even without connecting to a computer. The disad...vantages of touch displays include their higher cost than conventional ones, despite the fact that control via a computer is usually still more practical and visual. So this function is relatively rare these days.

Rated input power of the printer, in fact — the highest power consumed by the device in regular operation.

This indicator is directly related to the specs of the device, primarily the overall performance. However, generally, 3D printers are a relatively economical devices: among solutions that are not related to specialized industrial equipment, values of more than 1 kW are extremely rare, and even in the most performant models this figure does not exceed 3 kW. For such capacities, an ordinary household power outlet is quite enough, so you have to pay attention to power consumption mainly in specific cases — for example, when assessing the load on a voltage stabilizer or a backup power source.
