I would like to know if you do modeling and I also would like to know if you can accurately print threaded rods and bolts.

I have a small 4" bracket I would like to have made out of steel but it has a 1/2"-13 thread size its basically a nut thats being used as a bracket.

Please let me know your thoughts on this. my name is Jeff and I can be reached by phone thank you for your time.

I look forward to speaking with you.

Hey Jeff,

in my experience threads that small don’t turn out usable at all on normal FDM machines. Especially if you want to use them in conjunction with metal parts, they will wear out quickly and create a lot of friction, if they work at all. Different, more high-end technologies might be able to produce better results, but SLA prints for instance tend to be more brittle and less long-lived.

So if there is any way you can (CNC-) machine the counterpart to your threaded bracket out of metal it would likely be the better solution.

Sincerely,

Jonas

Another classic hack solution to this problem is to design a plastic part that holds a metal nut. That way the tight tolerance and smoothness for the bolt is achieved but you can extend that into any shape of interest. Still not at strong as metal, but many times it’s a great way to cheat that problem. It’s even been used in the designs for building 3d printers.

hi Jeff I do modeling in solidworks. Sorry for the delayed response. I also have 3 3D printers and a prototype machine shop in China for short run at very reduced prices. I do prints at half pice. Feel free to contact me. Stevemeitner@gmail.com 978-808-3474
