Carlo is very fond of printing with nylon, and recently we have also used many types of lawnmower nylon thread with great results. The problem with nylon is it doesn’t stick to the plate easily. Someone uses a sheet of wood, others use hairspray on a glass bed. There are huge threads on this but it looks like the warping problem is really difficult to overcome.
We tried buying a Garolite plate designed for the Afinia
We lightly sanded it to improve the adhesion, and it works fine. Doesn’t cost too much (the worst part was the shipping costs for Italy) and is worth a try.
