Everyone in the 3D printing world has their own ideas for the best 3D printing adhesive and a preferred print surface.

The technicians at Fusion3 have tested very trick for adhering a print to the print bed and every print surface on the market. We’ve found, across the wide variety of 3D printing filament, there’s no better adhesive than a purple glue stick and a plain old glass print surface (especially when used with a multizone heated build surface as found on the Fusion3 F400).

From the thousands of hours of printing, we’ve found that different materials work best with different amounts of glue and different ways when removing from the print bed. Here’s what we’ve found:

MATERIAL

LAYERS OF GLUE

(APPLIED PERPENDICULAR TO EACH OTHER)

TO REMOVE FROM PRINT BED

PLA

1 Layer

Remove as quickly as possible after print finishes while bed is still warm. If having trouble removing (especially with large parts), manually heat print bed to 70c to soften the first few layers and make removal easier.

ABS

3 Layers

Wait for bed and part to completely cool. Part should self-release from the bed as it cools. For smaller ABS parts the part scraper may be used but only if needed.

Nylon

2 Layers

Heat bed to 50c and work scraper under the part carefully to remove.

ColorFabb XT, XT-CF20

2 Layers

Use part scraper to remove finished part.  Material will not self-release from bed but adhesion should not be too strong.

Polycarbonate (PC)

2 Layers

Wait for bed to cool and remove with part scraper.

PETG, PET

2 Layers

Use part scraper to remove part from a cool bed.  If part is difficult to remove, heat bed to 70c and work scraper under the part carefully.

ASA

3 Layers

Wait for bed and part to completely cool. Part should self-release from the bed as it cools. For smaller parts the part scraper may be used but only if needed.

Flexible (TPU, TPE)

2 Layers

Use part scraper to remove from bed.  Since material is highly flexible it should be easy to work the scaper under the part.

HIPS

3 Layers

Wait for bed and part to completely cool. Part should self-release from the bed as it cools. For smaller parts the part scraper may be used but only if needed.

Other materials

2 Layers

Use part scraper to remove from bed.
