3d print wont stick or bed adhesion is sometimes very hard to get right when 3D Printing.

3d print wont stick Top Rated Options

Here are our top three 3d printer build surfaces we recommend to get your 3d prints to stick without fail. There are plenty of other options out there with new technology developing everyday. We picked PEI, Borosilicate Glass and BuildTak as our top three picks because they are cheap, easy to use and have a good track record to work.

PEI (Polyethermide) Sheet – Top Pick

We have had by far the best results with PEI Sheets as far as getting 3d prints to stick. You” want to buy the one with 3M Adhesive on the back to prevent it from pulling up when printing large parts or buy the really thick stuff.

These sheets hold up very well over time and are resistant to scrapes, wear and are easy to clean. After a 3D Print is complete wait for the bed to completely cool to room temp and then remove your part.

Part removal methods (applies to all);

Small Parts: Just pick them up they should come off easy.

Medium or Large Parts: Tap/Hammer Method (give the part a delicate whack and it should release)

Short or Fragile Parts: Pry Method (Take a wire cutter or scraper to a corner and lift an edge to peel up the part)

Parts come off the PEI surface very clean and have a mirror finish on the bottom side of the print.

Borosilicate Glass Plate

Glass is a great choice for getting 3d print wont stick to work. It’s pretty versatile in what you can do with it and it makes for easy cleanup between parts. It has been known to have issues when printing large edge to edge parts. Using a Glue Stick, Hairspray (Aqua Net) or a special sticking liquid helps with this issue. However, you have to clean the glass frequently and re-apply the sticking solution to the bed.

Be sure to let the glass bed completely cool before pulling off the completed 3d print wont stick part. Also be sure to program the home safety height as you’ll need bed clips to hold the glass in place on your build platform. Glass is one of the most widely used print bed surfaces but this is quickly changing as people are switching to PEI Sheets and BuildTak type surfaces.

3D Printing Build Surface

3D Printing Build Surface are becoming more and more used and are even coming with 3d printers these days. The most household name is BuildTak and these are thin sheets of material to help the filament stick during printing. They come adhesive backed and stick to the build surface or a thin sheet of metal. These are a great solution and often work too well…

The reason we have listed this one third is that we have found a couple hurdles with this material. When printing thin layers or for example when a first layer of a print fails the thin layers are almost impossible to get off…

We found the only way to actually get the 3d print off is to reprint directly over it where the layers are high enough to pull or hit off. Another issue with the material is it is easily damaged. This makes more work to peel off the damaged sheet and apply a new one. It’s for this reason we have it last but it’s still a great choice for bed adhesion. We recommend sticking it to a semi-thin piece of sheet metal and then bed clipping it on for easy part removal.


These are our top favorites to get your 3d print wont stick fixed. There are many more choices out there and new ones are being developed all the time. There are some pretty neat carbon fiber and glass fused materials coming up that we will review soon… So stay tuned for more great ways to get your 3d prints to stick.
