Several alternative methods can be used for 3D printed assemblies, including:
- Snap-fits: These joints allow parts to snap together without fasteners. Depending on the application, they can be designed with different levels of snap fit, from loose to tight.
- Adhesives: Depending on the materials used for 3D printing, adhesives can effectively join parts together. For example, cyanoacrylate (super glue) works well with many plastics.
- Living hinges: These flexible joints can be printed as part of a single piece, eliminating the need for separate parts and fasteners.
- Threads: Threaded holes and screws can assemble 3D-printed parts together. This method can be particularly effective for larger or heavier assemblies.
- Magnets: Depending on the application, magnets can conveniently hold 3D-printed parts together. This method works particularly well for cases and enclosures.
Each method has advantages and disadvantages, and the best option will depend on the specific requirements of the assembly. It is essential to carefully consider the design and materials used for 3D printing when choosing an assembly method.
