WebApr 14, 2024 · In additive manufacturing, also called 3-D printing, one of widely used materials is polylactide thermoplastic polymer (PLA) by means of the fused deposition modeling. For weight reduction purposes, infill density is an often used feature in slicing for 3-D printing. We aim at investigating the effect of infill density on the mechanical … WebMar 10, 2024 · In addition, the PLA melt point impacts its heat deflection temperature, which is the temperature at which the material starts to deform under a load. As the melting point of PLA increases, its heat deflection temperature also tends to increase, resulting in better thermal stability and resistance to deformation at high temperatures.
WebOct 13, 2024 · The average rate of shrinkage of PLA is 2% but a range of 0.8% to 3% is generally assumed. The actual shrinkage can vary depending on the printing temperature, cooling rate, or the additives in the filament. In comparison, a high-temperature filament like ABS can shrink by up to 8%. This is also one of the contributing factors for why high ...
