Scientific background
Additive manufacturing – also generally referred to as 3D printing – is one of the mostly researched manufacturing process worldwide currently. 3D printing is used in various fields, including the vehicle industry, especially for individual product fabrication and prototype preparation. Nowadays, the most widespread technique among the various 3D printing method is the extrusion-based Fused Deposition Modeling – FDM, also called as Fused Filament Fabrication – FFF, which during its operation builds the desired product layer-by-layer through melting a thermoplastic filament material. For FDM/FFF-based additive manufacturing the polymer used in the largest amount is a biopolymer, namely the poly(lactic acid) (PLA). The PLA has similar properties like most of the commodity plastics, however, its relatively low toughness and heat resistance limits the potential fields of application. Since both the FDM/FFF printers, both the required PLA materials can be obtained at a relatively low price, users tend to prefer this type of printing more and more in the belief that using PLA means no harm to the environment, since it is biodegradable. Only few are aware that PLA does only biodegrade in proper industrial composters. Currently, without being selectively collected, there is no chance it would be degraded properly, which means it is just another plastic material increasing the environmental issues due to the increasing popularity of 3D printing.
Aim of the research
The proposed research serves a dual role. Firstly, the development of PLA-based 3D printing filaments with properties (thermal stability, toughness) superior compared to the commercially available ones, thereby making them suitable for vehicle industry purposes. Secondly, analysis of the possibility of recycling the PLA-based 3D printed products by the end of their lifecycle.
Tasks to be performed
• Literature review. Analyzing the current state of the science regarding the fused deposition-based additive manufacturing techniques, especially with PLA polymer, and the effect of additive and filler materials onto the properties of the printing filament.
• Material development. Analyzing the effect of various reinforcement and filler additives, performing mechanical, morphological and thermal characterization.
•Analyzing the recyclability of the developed materials. Optimization of the recycling process. Morphological, mechanical, and thermal analysis of the recycled materials.
