PEI VS PC sheet
September 07, 2017 10:32AM
Guys i need some help for choosing the best surface for printing.

I mostly print abs so keep that in mind.

My last experience with a printbite sheet was awfull so i am thinking of jumping to one of the above.

What is the best for abs . I ve read that users are very satisfied with grinded pc sheet. And it is easy to found and cheap here in greece.

What about pei is this better than pc ?

Also where i can find double sided tape 3M which can stand this temperatures ?

Any help would be perfect.

PEI all the way. I use it for ABS for 6 years now and never looked back.

On my old machine i use a 0.8mm PEI coated fibersheet attached to the heatbed with clamps. On my new machine i put PEI foil on a magnetic sheet that already had a heat resistant adhesive. On the printbed i have the same magnetic sheet. This is an ideal combination for me since the magnetism prevents any buckling but allows for stretching. The magnetic sheets are acting as heat spreaders so i even get a very even heat distribution on the surface. Detaching a print couldn't be easier, i peel of the top sheet from the bottom sheet, then peel of the foil from the print.

I switched from using PEI to PrintBite for printing PLA. With PEI the print was sticking too firmly and was often difficult to remove.

Where did you get the magnetic sheets! This really sounds like something I want to try....

I bought these [www.smagtron.de]

in theory those would begin to break down at any temp higher than 77c have you seen any problems? do you print at ABS temps?
