Ein vom MIT entwickelter 3D-Drucker kann in einem einzigen Vorgang einen voll funktionsfähigen Elektromotor herstellen – das Team musste den Linearmotor nach dem Drucken nur magnetisieren, die Motoren kosten jeweils nur 50 Cent

The endgoal of these fuckers seem to be near Star Trek utility.
And just like that, this technology will be bought, shelved and never seen again.
it’s wild to think we’re getting to a point where you can just print a functional motor for basically pocket change. that single-process multimaterial extrusion is a huge leap over the usual way of having to assemble everything manually. definitely feels like we’re one step closer to those star trek replicators.
This is very cool, but just to put the economics into perspective a cheap, small linear motor is the sort of thing you can buy online for like 99 cents right now. They probably cost less than 5 cents to manufacture, maybe even a lot less.
The real advantage of 3d printing is the on demand nature, it’s never going to compete with traditional mass production (much of which is basically just a highly specialized version of what’s happening here anyway, these days).
So what it’s really competing with is the supply chain, and for very low value standardized electrical components that is a *ridiculously* fast and sophisticated thing right now. Very sophisticated 3d printers have been able to do cool stuff for a while now, but besides custom shape fabrication they haven’t had a real economic impact and there’s a reason for that.
tldr: it’s cool, but I still don’t really see a use case
I know it’s fiction but the idea of STCs from Warhammer is a possible future with where 3D printing is going.
That website needs chemo
Now expose the motor to working conditions for extended periods. How does it perform?
If you are printing induction motors then there is not need to magnetise anything.
Without even scrolling 1 pixel, I see 15 adverts.
That’ll be for sure the last time I click on an article from that site… my god.
A 3d printer is just 3 motors and a heater so this is getting really close to printing a 3d printer.
>Most existing extrusion 3D printers can only switch between two different materials, so MIT News reported that the team built their own system and retrofitted to an existing printer.
Why build your own when you can buy multi tool printers from several manufacturers? It looks like they just modified [an E3D printer](https://e3d-online.com/blogs/news/toolchanger-the-update-youve-all-been-waiting-for).
