Adhesion: spray and glue for your print bed

Keep the first layer in place and prevent warping, while your print still comes loose once it has cooled.

Is your print coming loose from the bed, or are the corners lifting? A thin layer of adhesive keeps the first layer in place. Here you will find 3DLAC adhesion spray and the 3DLAC Stick, Magigoo glue sticks for common filaments and special versions for PP, nylon and flexible filament, and superglue for joining prints. Below the products we explain which one suits your filament. Read more…

Why use an adhesive on your print bed?

The first layer is the foundation of every print. If it does not stick properly, the print shifts during printing or the corners lift because the material shrinks as it cools (warping). An adhesive forms a thin layer between bed and print: while the bed is warm it holds the print, and once the bed has cooled the print comes loose again. With PETG on a smooth PEI bed it works the other way round: there the layer stops the print sticking too firmly.

Which adhesive should you choose?

ProductForFeature
3DLAC adhesion spray (400 ml)PLA, ABS, PETG and moreAerosol: an even layer over the whole bed in one go.
3DLAC Plus (100 ml)PLA, ABS, PETG and morePump sprayer, easy to dose.
3DLAC Stick (80 ml)PLA, ABS, PETG and moreStick: you only apply it where the print will be.
Magigoo Original (50 ml)PLA, PETG, ABS, ASA, HIPS and TPUGlue stick with a spring valve; according to Magigoo good for more than 100 prints.
Magigoo Pro PPPP onlyFor PP filament, which ordinary glue barely sticks to.
Magigoo Pro PANylon (PA) onlyFor nylon filament.
Magigoo Pro FlexTPU, TPE and TPC onlyFor flexible filament; tested with Fiberlogy FiberFlex, among others.

If you mainly print PLA and PETG, 3DLAC adhesion spray or Magigoo Original will do. For PP, nylon and flexible filament, choose the Pro version for that material, such as Magigoo Pro PP.

How to apply an adhesive

  • Clean the bed: first make the bed grease-free with isopropanol from our maintenance category.
  • Spray: spray an even, thin mist over the bed from about 30 cm.
  • Magigoo: shake the bottle, press the tip onto the bed so the valve opens, and only coat the area where the print will be. Do not squeeze the bottle, or the applicator may come off.
  • Removing: let the bed cool and the print comes loose. With the 3DLAC Stick this works most easily below 30 °C.
  • Cleaning: 3DLAC and Magigoo Original dissolve in water. Remove residue of Magigoo Pro PP and Pro PA with a wet, hard sponge.

For large prints in PP, nylon or flexible filament, Magigoo recommends a brim of about 20 mm. The Pro versions are intended for professional use: avoid contact with your eyes and wash your hands after use.

Joining prints with superglue

With a few drops, Weiss COSMO CA-500.110 superglue (20 g) quickly gives a hard, strong bond between printed parts, including PLA and ABS. This glue is meant for your prints, not for your print bed.

Tips for a good first layer

  • Warping with ABS and ASA: an adhesive helps, but also avoid draughts and use a brim or an enclosure.
  • PETG on PEI: a layer of adhesion spray or glue stick acts as a release layer, so your print and your plate stay intact.

Frequently asked questions

  • Adhesion spray or glue stick: which works better?

    They do the same job: a thin layer that holds the print while the bed is warm. With a spray you quickly cover the whole bed with an even layer. With a stick or Magigoo you only apply it where the print will be, so there is no mist on the rest of your printer. For PP, nylon and flexible filament, choose the Magigoo Pro version for that material.

  • Why does my print come loose from the print bed?

    Usually because of grease on the bed or because the nozzle is too high. Clean the bed with isopropanol, check the distance between nozzle and bed, and use the bed temperature that suits your filament. If the print still does not stick well, a thin layer of adhesion spray or glue stick helps.

  • Do I need an adhesive on a PEI plate?

    For PLA usually not, as long as the plate is clean and grease-free. PETG sticks so strongly to smooth PEI that it can damage the plate; there you use a layer of adhesive as a release layer. PP barely sticks to PEI; that is what Magigoo Pro PP is made for.

  • How do I get glue residue off my print bed?

    3DLAC and Magigoo Original dissolve in water: wipe the bed with a damp cloth. Remove Magigoo Pro PP and Pro PA with a wet, hard sponge. The wet layer turns white and is then easy to scrub off; dry the bed afterwards with a paper towel.

  • Can I use Magigoo Pro PP for other filaments?

    No. Pro PP is made only for polypropylene, Pro PA only for nylon and Pro Flex only for TPU, TPE and TPC. With other filaments a Pro version can stick too strongly and damage your print surface. For PLA, PETG, ABS, ASA, HIPS and TPU, use Magigoo Original.
