man, I wish this was on thingiverse...
Once the insert heats up, the plastic melts around the insert and when it solidifies it should hold the insert in place. If the hole is smaller than the insert, there will be extra plastic to remove at the end of the insert.
Hi, from what I understood from Mcmaster, and after I measured the insert, my guess would be that the holes have to be tapered, with the smaller diameter towards the tightening direction. Otherwise, I do not see much contact if the hole is straight.
I've never needed an iron to use screws with my prints before. Does it make them more fixed or something? I'm now curious!
I've also left holes for nuts, put a pause in the gcode and stuck the nuts in and then 3D-printed over top of the nut (leaving the bolt hole). It's nice to have options. - dhylands
I wonder uf you could just bevel a brass nut with a grinder and make your own inserts... - jclerico
It may be good to know that the inserts are available with a larger diameter flange. This is helpful in the event that you could pull the threaded insert out of the plastic when tightening anything to it. My company learned that the hard way. - jsherwin9856
This thing gives off fumes so do it outside OK - DavidK60
Having worked in recycling, we hate designers who use these things because they are a pain in the arse to separate from plastic, being tiny, hard to see and weakly magnetic. This leaves either painstakingly staring at casings to rip them out manually or wearing down the blades on shredders before separating them in a sink-float tank.Sorry I don't have anything positive to say here. £#€& threaded inserts. Please never use these with plastic that doesn't biodegrade quickly. - eng_Andy
I need to try this on the bottom of a digital camera, where it meets the Tripod... But IDK if it will burn up the camera... thinking about it... - AviationMetalSmith
What materials have you embedded these inserts into? Is PLA strong enough to take the torque of tightening a screw into the insert? I'm guessing that ABS plastic works well, but the printers I can use only use PLA filament. - pholy
I have done this, I also found that having a 3d pen helps as you can weld the inserts in with it if you need - NormanK2
