3D pens printing with PLA plastic

PLA plastic

— plastic of organic origin, produced from vegetable raw materials and related to biodegradable materials. Actually, one of the advantages of PLA over ABS is considered to be environmental friendly. However, in addition to this, this material has quite practical advantages. First, it melts at a lower temperature, which somewhat reduces the risk of burns. Secondly, the smell when PLA is heated is very weak and not as unpleasant as from ABS (similar to the smell of corn or caramel). Thirdly, this type of plastic readily sticks to various surfaces, it is suitable for drawing not only on paper, but also on metal, glass, ceramics, etc. In addition, PLA can be not only coloured, but also translucent and even luminescent. The main practical drawback of this material is softness: it solidifies rather slowly and is poorly suited for drawing “in the air”. In addition, products made from PLA are quite fragile and short-lived. PLA is considered a good material for beginner artists, including children.
