PLA is a very widely used filament because it does not release a disagreeable odor, It’s food-safe, it does not warp much, it requires less heating than most filaments and it can make rigid objects. You can sand, paint or glue it easily. You can often print without a heated bed, although It’s recommended for larger objects. It is a slowly biodegradable plastic when exposed to the environment. Pure grade Ingeo certified resins were used for the manufacturing of this filament, which has passed a defined set of tests performed by Nature Works to ensure the product quality. To change the printed surface appearance between glossy and matte, try varying the print temperature by a few Degrees.
