I’ll look for some examples tomorrow. But along with free handing sculptures, I’ve also used the 3D pen as a welding machine for my 3D prints. You can use it a bit like a tig welder, making welds to connect two parts with the same material and color as the print. It can be completely invisible with sanding afterwards. I also used it to fill in cracks in other things that broke. It’s both fun and super useful for functional parts.
Of course they wouldn’t be. They will find the worst possible to comply while not actually making it realistically usable.
Malicious compliance at its finest.
It only needs to be at a higher temp than the glass transition of the material. The higher temp in 3D printers is to transfer heat faster. That’s also why volcano nozzles exist to have a longer heat transfer area, needing lower temps or allowing faster filament flow. The flow of a 3D pen being ridiculously slow (you’re inherently slower than a printer when using a pen) it doesn’t need such a fast heat transfer.
I have this pen which is $60 on Amazon. I really like it. Used it with PLA PETG and ABS with no issues. It doesn’t need as high temperatures as 3D printer as the filament comes out much slower.
If you want to do full crab like the one in the article, not just front wheels like in the oldies video, you need to power the wheels. With 4 independent driving wheels you can switch between traditional 2 wheel steer, 4 wheel steer, crab (for parallel parking) and orbit for turning around in place. There is no transmission axle between the wheels so they can be independently rotated and controlled, just like on a film dolly.
The fact that now each wheel can be fully independent with their own motors makes executing this much easier than before without adding extra hardware, simply working with software.
They really should have bought Apollo…
