3D Printed Breakaway Connectors for Assembly and Maintenance

Designing for maintenance is essential, especially in situations where access is limited or repairs must be made quickly. One solution is using 3D printing to create breakaway connectors that facilitate easier installation and repairs. Firstly, a setscrew can be 3D printed alongside a shaft coupling with breakaway supports, allowing for easy installation without the risk of fused threads or loose connections. Secondly, a universal joint comprising of a flexible center connected to rigid ends can be designed with non-threaded pins held in place by breakaway supports. This enables easy replacement of the flexible portion while minimizing disassembly time. Ultimately, sacrificial supports are proving not only useful for 3D printing but also integral to the installation and repair process.
