@_x111 well there are tools for 15 bucks

Without testing you don’t know reliability, maximum voltage or current or breakdown voltage. And all of these could vary by filament type, print temps, etc.
I wouldn’t use these anywhere.
Well ABS hat something like 120MV breakdownvoltage, PET even more. Current is limited by the terminals itself by definition which are either 1,5mm² or 2,5mm² which is like 30A max. This is not to be used for mainsvoltage. This is supposed to be used for 12V or 24V systems. Already got some working on my lead-battery charger and they work well.
What do you think happens when passing 30A through that connections? Well Id say even PLA should be enough for it. But I wont use it.
I like these crimp shells, I would be a bit concerned if they were made of PLA as a bad connection could very much more easily melt it but polycarbonate would work a treat.
I absolutely love the idea and design, well done. I personally would not use them in any application were an overloaded/loose connection could product enough heat to set this connectors on fire.
I say this thinking there still is no flame retardant filament being produced for mass market?
@VolksTrieb if made from solid injection molded abs and even then they test connector designs to verify. But fdm parts can have flaws, adhesion issues, underextrusion, gaps, etc which would definitely degrade performance and safety.
@Daniel_Joyce like I said. Dont use it for mains. Use it for your hobbystuff.
@RJ_Make_RJ yes there are some.
@VolksTrieb
You don’t needs mains power to create a enough heat to set connectors on fire.
@RJ_Make_RJ
nobody said that. but somebody said something about insulation.
@VolksTrieb
Ah sorry about that I miss the conversation tree. @Duncan_Gunn made a good point about polycarbonate based filament, which makes my concern mute…
