Don’t own a large 3D printer yet? When determining what’s possible with a compact desktop 3D printer, think beyond the build volume.
This is the case when multiple or opposing surfaces need to be free of support marks, a design has complex overhangs, or a model contains cavities that would trap the liquid resin inside.
3D printing multiple pieces also opens up new opportunities, such as creating multi-material assemblies or combining rigid and flexible 3D printed parts to simulate over-molding. You can also get professional 3D product configurator software online.
When selecting a bonding method, your primary consideration should be the strength of the bonded joints, which is dependent on the ultimate use case of the parts:
- Chemical fastening: Use a bonding agent for art, scale models, and complex shapes that are not meant for functional use and to sustain impact.
- Mechanical fastening: Add screw thread or pockets to functional engineering parts that require a robust mechanical connection or if you need to repeatedly attach and
- detach components.
Splitting Your Model
There are two methods we recommend for splitting models: Add features to your design that will allow the prints to align themselves, or simply split the parts with straight cuts, requiring you to align them during the fastening process.
Regardless of which method you choose, if you have a large number of parts it’s also a good idea to add a unique identifier (letters, numbers) to each part to help you solve the puzzle during assembly.
