This PEI sheet is Pre-applied with 3M 468MP Adhesive Transfer Tape for your convenience.
PEI (Polyetherimide) , also known as Ultem, is a reusable, relatively maintenance free, perfect build surface for both ABS (with a Heated bed) and PLA (hot or cold), other materials such as Metal, Wood, ABS+ and many others also works just fine. PEI sheet is appealing due to its “no-surface-prep” conditions, which make it convenient to work with.Additionally, printing on PEI sheet requires no support rafts as parts adhere directly to the surface with no issue.
what's a PEI sheet?
Polyetherimide, more commonly known in its abbreviated form PEI, is a “relatively maintenance free” build surface that can be used for all types of filament on a heated or unheated print bed. It doesn’t require any additional adhesives such as glue or tape. In the 3D printing world, these PEI sheets are sometimes sold under the guise of brand names such as Ultem.
PEI requires “no-surface-prep” before use, which makes it very convenient to work with. The guidelines for use also suggest that using a PEI sheet on your print bed will eliminate the need for a raft or brim, as parts are expected to adhere directly to the surface without issue.
PEI has excellent mechanical properties, radiation resistance, high and low-temperature resistance, high-temperature stability and high wear resistance as well as good flame retardancy, chemical resistance, and electrical insulation characteristics. Not to mention…it comes in multiple colors as well!
How to Use a PEI Sheet?
The first step in adding a PEI sheet to your print bed is simple: remove the old covering or sheet. The easiest way to do this is to set the bed temperature as if you were printing with ABS (110°C). Wait until the bed is heated and then start in one corner and peel it off. Sliding a spatula across the surface (being careful not to scratch the aluminium plate) can assist you in breaking the adhesive sheet.
At this point, you should have to assess the print surface. If the remaining adhesive is just a thin uniform coating rather than uneven blobs, you can apply the new self-adhesive sheet directly over the top. If not, you have to leveling some denatured alcohol or isopropyl alcohol, using a scraper to give the heated bed to a clean smooth finish.
If you’re required to cut the PEI sheet to fit the print bed, you can do so with a knife or another type of cutting tool, trimming the corners if your adjustment screws are sticking up through the plate. If the PEI sheet is self-adhesive, remove the protective film by peeling back one edge of the PEI, but not too much though!
It’s very important that you scrape any bubbles or lumps out as you attach the sheet to your print bed. Be sure to take it steady and apply small portions at a time, starting along one edge and moving throughout the bed. Once the entire sheet is mounted to the platform, ensure no bubbles are showing up on the surface. You can use your printer’s scraper to smooth everything out until the PEI sheet is as smooth as possible.
After the PEI sheet is applied, don’t forget to re-level the print bed (that is, if your printer requires manual calibration).
