| Summary: | Fused Deposition Modeling (FDM) is one of the most popular 3D printing method that available on the market. The FDM 3D printing method uses plastic filament as the printing material. The currently commercially available printing material for FDM 3D printing methods is still very limited and expensive. Thus a new research to find alternative printing materials that can be used in FDM 3D printing process is needed. Polypropylene is one of the potential material candidates to be used as an alternative printing material for the FDM 3D printing method.
In this research, a simple plastic extrusion machine is being made to process polipropylene plastic into filament form. Four types of polypropylene filament is being made: high impact polypropylene filaments (PPHI), recycled polypropylene filaments from mineral water bottle cap (LBTAM), a blend of high impact blend polypropylene and LBTAM polypropylene (10% PPHI weight fraction up to 40% PPHI), and polypropylene/ramie fiber composites (volume fraction of 5%). The effects of PPHI weight fraction addition into PP LBTAM and 5% volume fraction of ramie fiber addition into PPHI on filament extrusion process parameters and 3D printing process is done by visual observation and dimensional measurement of 3D printing product.
The results obtained from this research shown that the simple plastic extrusion machine is capable of producing plastic filaments for 3D printing with a production capacity of 13,04 grams to 18,40 grams per hour. The addition of PPHI into PP LBTAM filaments improves the windability of the filament and reduces warping on filaments and 3D printing products. The addition of 5% volume of ramie particles into PPHI reduces the windability of the filaments and increases the z-axis orientation dimension of the 3D printing product. In this research, in general it can be concluded that polypropylene-based plastic filament has the potential as the plastic filament for FDM 3D printing application.
