Threading
threading creates thread on your product, enabling secure screw or bolt fastening for precise mechanical assemblies.

Threading is used to create internal or external threads on printed parts, allowing the integration of screws, bolts and other threaded fasteners. Threading can be achieved by various methods, such as tapping, heat-setting inserts, or directly printing the threads. It produces precise and durable threads that withstand repeated use, enhances the functionality and assembly of 3D printed parts, and improves the structural integrity of connections.
Threading is one of the 3D Plus hardware finishing services on AIHFABS. It is applied after printing so the part leaves production closer to a usable product—not only a raw build. Use this page to decide whether Threading matches your cosmetic, durability, or assembly requirements before you upload a file.

Finishing is quoted with the print. Select Threading in checkout, review price and lead time, and keep printing plus post-processing in one order instead of coordinating a second shop.
Threading can hide layer lines, even out color, or create a more uniform surface for display models, consumer housings, and review samples.
Depending on the process, Threading may improve wear, corrosion resistance, grip, or light diffusion so the part survives handling and end use.
When Threading is combined with printing, you receive parts that are closer to install-ready, reducing secondary work in your own workshop.
Ordering Threading follows the same 3D Plus software flow as a standard print. You do not need a separate finishing RFQ for catalog options.
Use STL, STEP, or another supported format. The quoter checks volume and geometry so finishing can be priced against the actual part.
Pick SLA, SLS, MJF, SLM, FDM, DLP, or CNC where applicable, then add Threading and any other 3D Plus hardware options the part needs.
Review supplier options, confirm quantity, and place the order. Printing and finishing stay on one timeline and one invoice.
Threading is typically applied to plastics or metals produced with industrial 3D printing. Compatibility depends on material, wall thickness, and whether the surface can be reached by spray, media, chemistry, or tooling. Deep recesses, thin walls, and optical faces may need design review. If the automatic quote cannot apply Threading to your file, request a manual quotation.
Need Threading on a batch, a mixed-material assembly, or a part that also requires tapping or painting? Keep those options in the same quote so lead time includes the full stack of operations.

Threading cuts or forms threads in printed plastic or metal. Wall thickness around the hole must hold the tap or thread. Heat-set inserts are an option when the printed material is too soft for a cut thread.
Tapping and threading remove material inside the hole and can raise a slight burr at the entry. Keep the thread length and major diameter in the CAD or the quote notes. Nearby thin walls may need a boss.
Printed threads are coarse. Threading cuts a cleaner internal or external thread for machine screws. Call out the thread spec (for example M3×0.5) and whether you need a heat-set insert instead.
Upload the CAD file, choose a print process and material, then turn on Threading. Price and lead time update on the same order. If the automatic quote cannot apply it, request a manual quotation and note fits or color codes.
