Brad there is actually 2 techniques for metal printing 1 involves the sintering proces using the binder and metal particles then there are 2 others called direct metal deposition

the 1st is using titatium

For metals, you can do "sintering" with medium power laser powder systems. It's pretty cool you can find more info online. but only practical for very hard to CNC objects.

I wonder if you can use that conductive ABS and then add a relatively thick electroplated layer of nickel or something.

I have actually ordered a roll and can get back to how it turns out when finished. If it hasn´t created lung burning fumes so both me and the dog is no more ...

fascinating - what do you intend to use it for?

This.

The closest I have seen to high strength objects is a few prints with Polycarbonate. Polycarbonate creates lung burning fumes, and probably should not be tried.

Doesn't the metal 3d printing technique used actually print using a binding agent and very small pieces of metal, then you have to bake it at the end? At least thats what impression I was under.

There is no melting point of Kevlar, there are 3d printing technologies that can print in metal already.

I think the heat required to melt the steel would melt everything else on the SD though unfortunately.

Just a what if sort of idea. Does anyone know if it would be possible to print with a high strength filament like kevlar or spectra? If it were possible we could make pieces to work in cars or other places that needed high strength.
