Own both now. Like them for different reasons.
Frostbite- what I’ve learned. Works well with PLA, PETG, but you do have to heat the bed, but not as much as with the BL Textured PEI.
I don’t consider it have a rough texture though as the transition from the law areas to the high spots is smoother than the textures PEI. You get a shiny finish with non Matte PLA.
Heat bed temperature findings.
NEVER print PLA at the default textured PEI settings. It makes the parts very difficult to remove. Also, do not try it with an unheated bed the first time. Start around 35 Deg C and then go up or down from there. Adhesion IS dependent on room temperature at cooler heat bed temperatures of 30C or less.
As stated, clean with soap and water and WASH BEFORE THE FIRST USE. I actually had the soapy water change color from the stuff it pulled off a new plate. Went from clear to lightly grey.
Great option for PLA / PETG when used correctly.
