Printing directly onto aluminum plate
-
Hi all,
Having some issues with printing PC onto borosilicate glass. I'm using this bed adhesive, and it seems to work too well. I ripped a small chunk out of one of my borosilicate build plates. I'm trying to find something else that is high temp resistant (up to 180C or more) and resistant to ripping out like this. Would a MIC-6 or ATP-5 plate work for this purpose with the adhesive?

@Surgikill I've printed a fair amount of polycarbonate on float glass (not borosilicate because as you've discovered it chips too easily), using my go-to solition which is 3DLac. The only filament I've ever had a problem with sticking too well is woodfill PLA. Aluminium is far too soft to use as a build surface.

You can also consider a 3-4mm thick PEI (Ultem 1000) plate. If high temp is needed find a plate without adhesive backing then use binder clips or Swiss clips to secure it to your heater - attaching rigidly with fasteners will lead to stress cracks in the Ultem, eventually.
With Ultem you may not need to use adhesive or as high of build plate temperature. Hopefully you could flex the parts off the surface and not have to use a spatula because it’s a polymer and even softer than aluminum!

@HebigT right now my adhesive releases when cool and stuff just pops off. I will have to check prices on the pei sheets, but I'm betting they will be more than the Aluminum. I'm using an e3d high temp bed.
