The next color will be Solid Red and should be here in September. If you have any suggestions on future colors please let me know. you can email to admin@intservo.com

I am also getting some newly announced ePC (esun new polycarbonate) by air. It has lower melting temp/glass point than original PC but has much much less warp comparable to PETG, also fire proof.
