It is important in studying and understanding the various way in which filaments properties being characterized. In order to 3D-print filaments research have been done on both thermal and mechanical properties of the new biodegradable Enviplast filament, granulate, pellet or flakes. In this project, pellets are extruded into filament. During the filament extrusion process, temperature and speed control played an important factor in producing ideal filament condition where little or substantial bubble formation is presented. Different conditions affect the filament properties such as darker filament color, production time or even bubble formation. The mechanical property was determined by tensile testing in NTU biological laboratory. By using the Instron tensile machine, test sample material undergoes tension. From the graph, an important factor such as Young's modulus, ultimate tensile strength, and fracture point was obtained. The thermal property was determined by DSC and TGA in the material laboratory.
