I really enjoyed using this material. I had to reduce flow by 8%, which is far more than I feel I should have, but prints came out within expectable dimensions and with very nice surface finishes after this change. The PCFR has a marginally less glossy finish to their normal PC blend that looks very nice for a whiteish filament.I have not tested the ability to resist flames nor do I intend to but I have been happy with the price, print quality, and temperature resistance which I found to be slightly better than ABS & ASA.
