3D People adds threaded insert options to online quotes

3D People has pushed threaded inserts out of the back end of production and into the quote stage, a small workflow change with a big payoff for anyone designing parts that have to bolt together cleanly. The London bureau now lets customers add insert installation while configuring a job online, so fastening is no longer something discovered after the print is already underway.

That matters because 3D People’s quote tool already does most of the heavy lifting in one pass. Customers can upload files, inspect parts in 3D, edit quote details, choose material, quantity and finish, and move straight to checkout. Threaded inserts now sit inside that same self-service flow, which means the decision can be made alongside geometry, material and finish instead of through email back-and-forth or a separate post-processing request. The standard option is a Tappex self-tapping metal insert, with heat-set inserts still available when part geometry leaves too little clearance around the hole.

For design-for-assembly, that is the real shift. Threaded inserts are not exotic, but moving them upstream changes how parts get drawn, priced and handed off. 3D People’s own guide lists M2, M2.5, M3, M4 and M5 metric sizes, and its white paper says inserts provide a consistent, repeatable and standardised fastening method while reducing machining operations and supporting repeatable disassembly and reassembly for maintenance and repair. In practice, that means the insert is no longer an afterthought tacked on during finishing. It becomes part of the part definition.

The company says the service works with all rigid polymer materials and is aimed at regular, repeatable assembly and disassembly without wear. That fits the broader direction of its business, which centers on fast-turnaround batches, just-in-time and made-to-order work, and end-use parts for industrial applications. Once inserts are built into the quote, the bureau is not just selling printed geometry. It is selling a more complete assembly-ready component.

Felix Manley, 3D People’s co-founder, framed the update as the kind of detail that changes a part’s usefulness in the real world. That is the right read. A threaded insert may be a small line item in the quote, but for a prototype that has to survive repeated screw-ins, or a production part that has to go together the same way every time, it is the difference between a print and a finished component.
