Well whatever works, right? :D Which printer models were you looking at?

That sounds like a pain having to replace the glass frequently though. How large is your printer? Maybe you can give it a try running that model on a larger one to see if it still suffers from the same issues.

I can see how that might be tricky with a large flat surface like that, how close is it to the full size of your build plate? I've noticed that the uneven heating and weaker magnetism near the edges of the platform can be a problem for things that get near the edge. Could be that a more...

Wow that sounds pretty rough, what sort of models were you printing that were breaking your glass? I've experienced the magnetic sheet lifting at the edges once before on a particular model that went right up to the edges of the plate, so I guess it could also be that your models are contracting...

That's interesting, the BuildTak PEI worked fairly well for me. I've briefly tried Gizmodorks as well but that sheet ran into an unfortunate incident with a polycarbonate print and was fairly short-lived. Maybe the difference you're getting could also just be down to the print settings or air...

Which brand of PEI are you using? I've had fairly decent results with Energetic and BuildTak so far. The z-offset can make a huge difference too, I tend to get vastly different results in surface finish by adjusting the offset by even 0.01mm or 0.02mm.

I have my printers are in an un-insulated garage so it gets down to around 5-10C ambient on colder nights and still maintains >60C in the chamber. Right now I'm seeing ~25C ambient and and 67C in the chamber. I don't have a bottom picture of that same part but here's one that shows the bottoms...

I've had mixed results getting ASA to stick to PEI, on some sheets it adheres really well and other brands don't stick well at all. Once I got it dialed in it worked very well though, sometimes with a little help from plain old Elmer's glue stick if it's a tricky model shape. The enclosure is...

It's using PEI on a springsteel sheet and Polymaker PolyLite ASA at 240C nozzle temperature / 110C bed temperature. The printer only has a 500W bed heater but it's also fully enclosed, without any additional effort to insulate it I get around 65C chamber temperature during prints.

I print a pretty wide assortment of model sizes and shapes, anywhere from small stuff up to 200-300mm parts. Tolerances tend to be pretty good too. down to around ~0.02mm if I calibrate a model to account for material shrinkage and all that. Here's an example ASA part that just finished...

There are some much cheaper printers than $3000 available now that can handle ASA very well. I print ASA almost exclusively in my Voron V2.4 and it was less than half that cost to put together.
