In accordance with ASTM F-2792, the FDM process is the extrusion of materials for the purpose of making thermoplastic parts applied on a layer-by-layer basis. In this process, a thread of thermoplastic material is deposited on a bed using the mobile head of the device. The material is exposed to a specific temperature in accordance with the heated material, so that the freezing and welding to the previous layer is done exactly after extrusion. The specifications of FDM machine in the UTAMLab are as follows:

Size: 20 x 20 x 20 cm

Number of nozzles: 2 pcs

Laying accuracy: 30 to 800 microns

Printing speed: up to 300 mm / s
