I read a post somewhere about a stronger high temp PLA made by makergeeks. I bought a roll and what I can tell you so far... It's very strong. It also has a post print baking process that nearly doubles its strength and brings it's warp temperature to 125c. Best of all, it prints just like PLA. Out of the 9 prints I've attempted I have succeeded 9 times. I cant say that about any other material then PLA. It's impact resistance is higher than ABS. And...it's food grade. I would love to hear other peoples experiences with this material.
