Process Optimization for the 3D Printing of PLA and HNT Composites with Arburg Plastic Freeforming

The industrial use of additive manufacturing continues to rapidly increase as new technology developments become available. Arburg plastic freeforming (APF) process is designed utilize standard polymeric granules in order print parts with properties similar those molded parts. Despite the emerging importance APF, current body knowledge regarding this still very limited, especially field biodegradable polymer composites. To end, poly(lactic acid) (PLA) was reinforced halloysite nanotubes (HNTs) by hot melt extrusion. PLA/HNT (0–10 wt%.) composites were analyzed terms their rheology, morphology, and thermal mechanical properties. A study processing these context APF performed ensure consistency 3D-printed, high-quality components. optimized machine settings used evaluate tensile specimens printed different axis orientations (XY XZ) deposition angles (0 45°). Specimens an XY orientation angle starting at 0° resulted highest In study, reported for first time, methodology achieved satisfactory results 3D printing evaluation successful be feedstock process.
