In addition i ve used gluestick to avoid pet sticking too much on the pei as recommended.

Pei sheet over glass.

I m looking for experience about printing petg on the smooth pei. The problem is that the sheet of pei i received was warped about 1 2 over 12 inches length. Polyetherimide or pei material is an amorphous thermoplastic with high mechanical strength and rigidity. The pei film is adhered to the glass bedplate with a semi permanent adhesive in order to maximize the lifetime of the pei print surface.

At 70c pla isn t sticking to it. This matches what i generally used on glass. Place the edge of pei that you peeled away flush with one side of the bed. Smooth pei plates may have a non uniform appearance under the pei as that is the adhesive visible through the pei sheet this is normal.

All plates and magnets are inspected to ensure full functionality to make sure they meet our standards for them. Ultem 2300 is a 30 glass reinforced grade of ultem pei and is the most common filled ultem grade. It just sort of peels right off and printing circles and arcs is impossible as the extruded plastic just doesn t stick to the bed. I ve wiped down the pei with a lens wipe so it should be clean.

Single 1mm thick sheet installs quickly on top of existing flat build platforms e g. As the interface between the printer and the printed object the print surface sees the most abuse of any part on your 3d printer and will likely need to be replaced at some point during the life of the printer. Everything i ve used just sticks to pei with no glue or hair spray or anything else required. Pei polymer is extruded by ensinger in sheet and rod shapes using sabic s ultem resin.

Bed at 85 on first layer then 90. Borosilicate glass abs and pla filaments along with many other materials print directly on to pei surface without the need for additional adhesives tapes or slurry. Made in the usa. I ve printed quite a few parts now using the stock bed temperature of generic pet profile.

You can choose any side for this the pei sheet is bigger than glass bed we will trim the excess in later step using a rubber squeegee spatula push the adhesive into the glass bed as you remove the back protective cover. While this pei surface on my printer bed is good for adhesion i had serious problems getting this sheet to stick to either the aluminum bed or a glass plate even using 3m 468 adhesive. Textured pei plates may have a non uniform color appearance as they are sprayed and the pei is baked onto the plate this. I ve run glass the craptastic preforated sheet that shipped with my printer painter s tape kapton tape and pei and vastly prefer the latter out of all of them.

Unfilled pei thermoplastic is translucent and amber in color with exceptional mechanical thermal and electrical properties.
