Abstract
Nowadays, because of the negative effects of plastic material, more and more researchers trying to find the best solutions both to obtain more environmentally friendly and sustainable product that responds as accurately as much as possible to the different needs of the market. On the last years, an attempt has been made to continuously improve the functional characteristics of biodegradable polymers. Also, the manufacture of products based on biodegradable materials using modern technologies, such as additive manufacturing, increases the advantages of this positive alternative. The authors of this work studied samples made from biodegradable materials such as PLA, Impact PLA Gray, Green PLA HD, Extruder BDP Pearl, Extruder BDP Flax and Fiber Wood with the experimental research plan took into account three input parameters (deposited layer thickness, infilling rate, and sample orientation). The presentation presents some experimental results regarding different characteristics, such as mechanical, dynamo-mechanical, tribological, thermal, morphological, and structural analysis. Take into account the results obtained, the process parameter "sample orientation” on the printing table during the layer’s successive deposition has a great influence on the mechanical characteristics (such as tensile and bending strength, modulus of elasticity and elongation) for the product manufactured using the FDM (Fused Deposition Modeling) additive technology. The obtained results highlighted the fact that the studied biodegradable materials can successfully replace the fuel-based plastics parts, from many industrial fields as automotive, medical, construction, furniture etc.
