3D printing allows for rapid prototyping and testing of new designs, but while this ease of creation is great, plastic can pose issues when fastening together parts as 3D plastic printed threads are not generally robust enough to handle repeated use.
Threaded metal inserts designed for plastic allow for strong, reusable metal threads to be put into 3D printed parts. These inserts can be installed in several different ways, ranging from press-in installation to heat-staking with a soldering iron. E-Z Press and E-Z Fin inserts from E-Z-Lok are suited for press-in installation applications, and the company's E-Z Sonic is suitable for heat staking.
According to the company, E-Z Press & E-Z Fin (Finserts) threaded inserts for plastic offer unparalleled ease and reliability for advanced 3D printing. Their design ensures a quick and straightforward installation process, saving time and reducing labor efforts. Furthermore, the strong hold they provide ensures longevity and reliability in all projects.
E-Z Sonic heat stake inserts can be installed with a soldering iron work by heating the insert to a temperature beyond the melting point of the thermoplastic. Holes are printed or drilled, and the heat stake insert is pushed into place, melting the plastic around it. E-Z Sonic inserts work well with 3D printing applications and products made from similar materials (see video, below).
E-Z LOK offers both the E-Z Sonic and E-Z Press inserts in assortment kits that contain a variety of either metric or imperial threaded inserts and matching installation tools.
