Broken Build Plate

Postby Mike101 » Thu Oct 27, 2016 6:33 am

I've just broken the glass build plate trying to remove the buildtak.
I have found the buildtak works well to stick parts to the plate but I'm only getting 100 hours of printing out of the buildtak before it bubbles up and causes issues.
I'm looking into making a build plate like the Zortax out of FR-4 or 5 board.
Has anyone done this?

I use a thin PEI sheet on glass. Works perfectly with PLA and ABS and are much more durable than Buildtak. Also printing on glass with hairspary or gluestick works well.

Heat the bed to 110C will make the buildtak easier to peel off.
If your glass has broken into pieces, we don't suggest you keep the buildtak above it. Or the peeled off buildtak may have some glasses stuck on it's back side which may do harm to your later plate.

borosilicate glass .. or the kind that comes with the printer

personally I have never had much luck with abs slurry or hairspray on glass .. at least not with shapes that are prone for warping.. they always come loose.

I have had the most luck with either thick kapton tape on glass, the geckoTek build plate or PEI sheet stuck on glass with sheet adhesive.

I'm having trouble sourcing the Borasilicate glass here some I'm going to use Robac glass which is used in fire places.
Im also going to get a build plate made up like my Zortax.

Well I don't know where you are but you could just use any old glass in a pinch.

I ended up get FR-4 Board machined with 1mm holes every 10 mm like the Zortrax. Its is a much better set up than glass and build tack. We have done 8000 hrs of prints and rarely have a issue.

Just like Trhuster, I use a PEI sheet, and it works very good.

I replaced my Buildtak sheet more than 9 times until I decided that it is not durable enough nor suitable for large ABS prints.
So far I have printed +300 hours on a 1mm PEI sheet and Hatchbox ABS, no complains. That might be a quick fix. I bought the sheet for 22 dlls.

Anyhow... Mike101's setup looks very interesting. Probably Ill also give it a try.
