Review on 🌈 Proto Pasta Translucent Iridescent HTP21705 ICE Filament 1.75mm by Andy Jolley

I'm so disappointed with the proto-pasta HTPLA filament. Forget it's more than triple the price of standard PLA. Apparently heat treating just doesn't work on small parts. The parts I printed were to extremely tight tolerances on size and ability to withstand the summer heat/sun. Any attempt at heat treatment, even at the lowest times and temperatures recommended by the manufacturer, resulted in warping before the part had even reached the opaque state. Tech support suggested that I print "negatives" of the parts, heat treat them, and then use those negatives to keep the parts from deforming even during the heat treatment. Negatives printed at 100% coverage and using many more filament than a single part warped/lost shape at the lowest temperatures before reaching the opacity stage. Wasted time and money. I cannot recommend Proto-Pasta HTPLA based on my experience.
