If your model is too big to be printed during one print and you’ve decided to divide it into smaller pieces and print them separately, you can easily glue them together using an adhesive. Make sure that you choose the kind of glue which is suitable for particular materials to ensure full bond strength and durability.

Preparing the Print

Preparing the Print

At first you have to prepare the surface for gluing. It has to be rough so as to increase the adhesion of the glue. Use 150 grit sandpaper. Next, clean this surface with a piece of cloth damped with petroleum ether off dust and oil.

Gluing the Print


  • Cover the surface with glue. We recommend using cyanoacrylate glue for plastics.
  • Spread the glue across the surface.
  • Put the two parts together.
  • Leave the print for the time required by the producer of the glue. To ensure proper bonding, use clamps which will keep the two parts as close to each other as possible.

Finishing off the 3D Print with a Grinder and Sandpaper

If there are glue residues, remove them using a grinder or a piece of sandpaper. If it is possible, remove dried glue residues with a scalpel.
