How to assemble 3D printed parts with rib fasteners

Compare different methods for creating threads in your parts and follow step-past-ill-use instructions on how to install your fasteners.

Threaded fasteners for 3D printing

Eastern Samoa a guideline the minimum wall thickness or so a wander should match the diameter of the fastener (e.g. an M5 fastener requires a stripped of 5mm fence thickness around the rib mess). If surround thickness is too low parts tin pop and distort due to the added stress and in some cases (particularly FDM) delamination or fracture can occur.

The table below introduces the rib fastening methods that are best right to 3D printing.

Process	Description
Inserts	Popular method used on a regular basis that gives a strong metal on metal connection but requires additive components and facility
Embedded nut	Fast method for securing components. Precise contrive and impress are needed
Self tapping screws	One polish off method acting of securing parts that is non clothed to repeated disassembly
Cutting threads	Stabbing a thread offers design freedom notwithstandin proper tapping subroutine is important
Printing threads	Non suited for small threads (less than M5) and requires high printer point/resolution to print accurately

Note: Drilling the pilot/coalition hole to the desired diam post-printing process, before implementing any of the fastening methods discussed therein article, will typically give a more accurate diam compared to a 3D printed hole.
