There are new high strength pla filaments coming out but none of them get around the temp thing. It doesnt have to be boiling water. Just sitting in the sun will warp a part. This is the only reason i dont use the stuff. Other than that its great to print with. Petg is awesome. The layer bonding is like no other filament. The glass point is close to abs as well. Super strong stuff. There are alot of manufacturers coming out with the stuff. i cant stand chinese filament but sampled some of the petg from esun, it was awesome. Just like colorfabbs stuff. Its just not available yet, but soon i hope.
