4. The result of the polymerization is small pieces of raw material polylactic acid plastic which can be converted into an array of PLA plastic products. What are the benefits of PLA products? PLA requires 65% less energy to produce than traditional, petroleum-based plastics. It also emits 68...

M: What is it made of? W: It's made of clay. M: Who made it? W: I made it by myself. I have made ten dolls like this. M: You're great. When did you learn to make them? W: I learnt to make them two years ago. M: Could you make one for my sister? W: Of ...
It is PLA-coated paper, aka biodegradable coated paper. PLA (Polylactic acid) is a new biodegradable, eco-friendly material made from the refined starch of renewable plants (like corn.) The raw starch is converted into glucose first, then to high purity lactic acid, finally compound Polylac...

Bioplastic is made from plant material and it should degrade relatively quickly in landfills and, in some cases, compost bins. The most common forms are starch-based (often corn starch), like polyactide (PLA) plastic, which is the most common form. You'll find PLA in things like biodegrad...

Of course. Plenty of other thermoplastics can be used with FDM 3D printing, but those that can be fairly compared to PLA and PETG are: ABS (acrylonitrile butadiene styrene): This can make high-strength parts of decent quality, but the risk of warping is a little higher, especially for des...
