Tips and Tricks for Gluing 3D Prints
Common Gluing Problems and Solutions
Gluing 3D prints can sometimes be tricky, especially when dealing with larger or more complex models. Here are some common problems you may encounter and solutions to help you overcome them:
Warping: If your 3D print is warping, it can be difficult to get the pieces to line up correctly when gluing. To prevent warping, try printing with a heated bed or using a brim or raft to help anchor the print to the bed. If warping has already occurred, use clamps or other tools to hold the pieces in place while the glue dries.
Gaps: If there are gaps between the pieces you’re trying to glue together, it can be difficult to get a strong bond. To fill gaps, use a filler such as epoxy or a putty specifically designed for 3D prints.
Blobs and Strings: If your 3D print has blobs or strings of filament, they can get in the way when gluing. Use a sharp blade or sandpaper to remove any excess material before gluing.
Best Practices for Gluing 3D Prints
To ensure a strong and lasting bond when gluing 3D prints, follow these best practices:
Choose the Right Glue: Different types of glue work better with different types of filament. Check the manufacturer’s recommendations for the filament you’re using and choose a glue that is compatible.
