PLA Gets An Upgrade
PLA Filament has fast become the Filament of choice for many 3D Printing enthusiasts as it is relatively inexpensive, it is environmentally friendly due to it being corn-based, and though very slowly, it does biodegrade. Even though its popularity is increasing, there are still many enthusiasts and professionals that don’t see PLA as a viable 3D Printer Filament choice. This is because it can be easily warped by heat, as a PLA-made object is not able to keep its shape when exposed to temperatures above 120 °F. Thanks to the Industrial Technology Research Institute (ITRI) in Taiwan, there may be a solution. The research team at ITRI has almost doubled PLA’s heat resistance (212 °F) with a new blended PLA Filament that cools and bonds faster than standard PLA. ITRI’s new PLA Filament can also be manufactured from grains and lactic acid, the latter is normally found in fermented dairy-based foods, such as yogurt. This new heat resistant PLA will allow Makers, hobbysits, and professionals, who don’t like the negative environmental impact of ABS Filament, to use this new PLA on a wider range of projects.
