New materials are available for the well-known thermal process of 3D printing which involves consecutive deposition of layers of heated thermoplastics. This means that machine components can be made not only from the most common plastics, such as ABS, but also from PLA, HIPS, PET, PVA, PETG, PC, and others. By means of 3D printing, intricately shaped parts can be produced in a flexible manner and prototypes can be easily fabricated from various thermoplastics. This paper demonstrates the use of a thermoplastic aliphatic polyester (PLA) for 3D printing of a part intended for operation under mild thermal loading. One of the advantages of PLA is its good degradability. This is because its production is based on the use of corn starch or dextrose. Despite this, PLA structures can be created which exhibit higher hardness and strength than ordinary ABS.Keywords: 3D printing; PLA; thermoplastic materials; renewable resource; polylactid acid
