Print Speed
The material feed rate provided by the pen. The higher this speed, the faster you can work with this model; on the other hand, the rapid supply of material requires increased accuracy and serious skills. The maximum value of this parameter in modern 3D pens is about 40 mm/s. Models with adjusted speed is also available (see below); for them, usually, the highest speed of operation is given in the specs.
Display
The availability of a
built-in display. Usually, these are the simplest single-colour screens that display the basic operating parameters — speed and/or temperature. However, even such a display makes the pen more convenient and allows you to get important information about its operation.
Tip Material
The material of the pen tip.
— Ceramics. Usually, high-durability varieties of ceramics are used in 3D pens, which also have low thermal conductivity. The latter has a positive effect on the quality of work, and also reduces the risk of getting burned. Theoretically, ceramic is a fairly brittle material, but practically, to damage such a tip, a very strong impact is needed, and the plastic body of the pen is more likely to crack than the ceramic nozzle. Thereby, most of the modern 3D pens use ceramics.
— Metal. Metal tips are considered more reliable and impact resistant than ceramic ones, and are somewhat cheaper. However, in fact, these differences are usually not noticeable. But the thermal conductivity of metal is significantly higher than that of ceramics, which is why such a tip heats up quite strongly during operation and requires additional care. Thereby, this material is much less common than ceramics.
