The Industrial Technology Research Institute (ITRI) based in Taiwan has developed a food-grade quality polylactic acid (PLA) material which can resist temperatures up to 100°c without deforming.
PLA is a material commonly used in 3D printing. It is a thermoplastic aliphatic polyester derived from renewable resources – such as corn, tapioca, or sugar cane. PLA materials are completely biodegradable, non-poisonous, and heat-resistant. But it’s the level of heat resistance which many researchers – including those at ITRI – have been focusing on in their PLA development.
