Problem in using Poly carbonates filament in ultimaker 3

Recommended Posts

 i was using polycarbonate filament in Ultimaker 3 to print a 20*5*5 cm3 object. I observed a problem,that the material was not sticking to bed surface. I tried doing a small print which was printed very well. I kept bed temperature 105C and nozzel temp 260C. Any suggestion how to solve this issue?? May be changing bed (suggest material) or changing settings?

 

Thanks in advance

Having done some testing with PC, I can confirm that you need to sue something to make the PC stick to the glass. Glue is ok for small parts, adhesion sheets or something similar for big parts, and a brim or a raft is mandatory. Brim for small things, brim or raft for big things depending on the shape of what you're trying to print.

 

I printed a small cable holder thing, no bigger than 5 x 3 x 2 cms, print time was about 30 mins, and, when it was finished, I could see that the only reason it was still sticking to the glass was because the glue was still holding the brim thus keeping the part down. But the underside of the part itself was almost completely free of the glass bed and the glue.
