Hello, This will be short but sweet.
The key to a long lasting Pei print surface is: Let it cool down to part removal Temp.
Pulling a part off at full adhesion and temp will only warp the surface and pull up the silicone adhesive underneath it. Not only wait till it cools down, don’t use acetone on it (it will ruin it) to clean up. Parts printed with a material (PC,NYLON,PEEK)high water absorption will pull away at the Pei and leave bubbles if the adhesion is too high.
With this idea in mind, it might be smart to remove Pei and print on glass(Borosilicate GLASS ) with abs slurry for PolyCarbonate, to protect the Pei from Acetone degradation and elite scrutiny
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (~3 × 10−6 /°C at 20 °C), making them resistant to thermal shock, more so than any other common glass. Such glass is less subject to thermal stress and is commonly used for the construction of reagent bottles. Borosilicate glass is sold under such trade names as Simax, Borcam, Borosil, Suprax, Kimax, Heatex, Pyrex, Endural, Schott, or Refmex, Kimble.
