Effect of heat treatment on the tensile properties of incrementally processed modified polylactide

Abstract

The article presents the results of strength tests in the form of a static tensile test on the INSTRON 5967 testing machine. Samples were made with the use of the Prusa i3 MK3 3D printer, by modeling with a plasticized material (FFF) made of ABS copolymer, polylactide and its modified variant. According to the information provided by the manufacturer, heat-treated modified polylactide has mechanical properties similar to ABS copolymer filament. The publication also discusses the method of manufacturing elements subjected to the tests, the heat treatment process, as well as changes in material properties as a result of this treatment. Based on the test results, it was found that the annealing process increased the proportion of the crystalline phase, which significantly improved the strength properties of the modified polylactide.

Manufacturing Polymer Model of Anatomical Structures with Increased Accuracy Using CAx and AM Systems for Planning Orthopedic Procedures

“…As mentioned earlier, the preparation of the process for the device occurred in the PrusaSlicer software environment. All models were printed from a PLA thermoplastic polymer [ 47 , 48 , 49 ]. It is one of the most widely suitable polymeric materials in the additive FFF method.…”

Durability of chain transmission obtained using FFF technology

“…Material extrusion (MEX) technologies are rapidly developing due to their congruence with widely used thermoplastic polymers in commerce, ease of implementation, and general availability [10,11]. Hence, they are increasingly used in commercial, research, and hobby sectors for manufacturing machine components and developing functional engineering prototypes and systems [12,13].…”

“…Choosing to produce a segmented chain was due to the search for a practical application of machine elements produced using rapid prototyping techniques. FFF technology was selected due to its availability, thermoplastic materials with diverse properties [16], competitive prices offered by device manufacturers compared to other devices using different additive technologies, and the possibility of producing the analyzed chain drive [10,17].…”
