Joining parts of threaded rod by screwing them together - for 3D-printing

Theoforus — Mon, 01 Jun 2020 19:33:24 GMT

I am trying to design a threaded rod for 3D-printing. The plan was to make many parts that would be screwed together. The question is: How can I control the threads so that the threads on the rod will allign and work as one spiral when

assembled?

Hey reidhardr,

The Fusion 360 Collaborate forum is intended for the Fusion Team and team related topics. I'm moving this post to the Design, Validate, & Document forum where it's more likely to draw some attention.

Here's one possible method.

Create the full length threaded rod.
Use the Split Body command to separate this into the printable lengths.
Create the joining threads male and female sections as separate bodies.
Use the Combine/Join tool to add these to each end of the bodies from step #2.

Post your file here (File/Export/Archive file *.f3d) if you have any trouble with this.

The easy part is the modeling. The hard part will be printing unless you're using an SLA printer 😀 FDM printers don't like parts with knife like edges. You'll also need to chamfer the ends of the threads to actually get them to thread together.

Here's a screencast showing how to get the threads aligned perfectly: (If the screencast doesn't show up eventually, here's the link: https://knowledge.autodesk.com/community/screencast/53800af2-5605-4605-8fdf-951e30c273d1)

Many steps there, but I´ll give it a try. Thanks for taking the time to help me out.

I´ll be happy to hear your voice explaining if you´re making some more videos - that would help me a lot (if it´s possible of course)
