Prints similar to the matte surface from the Amazon PEI after sanding I assume? I have PEI on the way from McMaster but I would prefer the matte finish.
I was trying HIPS yesterday with no luck sticking at 80c. It could be the material, its not sticking to abs very well either. I will order a different brand to try.
I recently sanded my bed and have been trying lower temperatures, and with dual extruders tried HIPS - it is hit or miss for sticking, I printed 2 parts on rafts last night, one stuck, the other didn't. I had to print rafts because it was using a lot of support that just wouldn't stay stuck to the bed.
For PVA, I'd be tempted to add PVA glue stick.... seems logical right?
BuildTak is great, sticks well. It has a distinctive pattern though. PEI does not. For some things I can incorporate the pattern into my work. Or if its a part that you won't see the first layer. It's good stuff though.

I've been using a small piece (5" x 5") of BuildTak to print PLA things on my old printer. I've done about 130 prints on one piece of BuildTak and it's still going strong. Holds tight but when I wedge the sharpened putty knife under a corner the item pops right off.
The sharpened putty knife came with the Afinia printer, stiff blade 0.8mm thick and 51mm wide with a stout molded handle. Sharpened on one side so the edge is flush with one side of the blade. Made by CRISTIN Germany.

Just a quick update. While I had PLA sticking very well, ABS was still not cooperating. Yesterday I tried a 100mm x 40mm rectangle in ABS but I increased the print bed to 115C (had to wrap it in a blanket to get it that high). The ABS stuck very well and didn't even release when the print was complete and the temperature was back down to around 30C. The bed managed to maintain about 112C during the print.
I'll try a lower bed temperature to find a better stick/release set of temperatures for the ABS I'm using.
So, I stumbled upon this thread after recently getting my solidoodle press and researching a better surface then glass for abs printing. I read through as much as I could but i m not going to lie I didn't read it all.
I did read somewhere that you mentioned you were going to try to use permatex copper spray gasket to adhere the PEI to the mounting surface. Did that ever work out? I plan to use 18 gauge 6061 aluminum as the base material that I attach the PEI to. I will cut them both to the size I need on the waterjet at my job.
anyone print ninjaflex with PEI? even with ZERO for the bed temp it adheres so well its near impossible to get off.. on the matte side.
I havent tried the smooth side yet
so i did get the part off but holy crap it was hard.. i had to pry and peel , rinse repeat for 20 minutes.. came off in 1 piece and looks great. but holy hell it was awful.
even more reason i need detachable plates, or something to change out 2 types of PEI and glass.
