This is Mjolnir (mjolnir by januszeko - Thingiverse) printed on my UMO+ in ProtoPasta stainless steel and Colorfabb Copperfill, Brassfil and Bronzefill. Polished in self designed rock tumbler (Affordable Rock Tumbler by J_T_3_D - Thingiverse) for 48 hours and finished with buff wheel.

What have you printed with these materials? Please show and share :slight_smile:

Here is a Proto-Pasta Stainless Steel Print and a Filamentive Carbon Fiber I did

You’re welcome :slight_smile:

Are metal filled filaments stronger than normal plastic or is it just for the metal look?

In my experience they’re actually weaker and more brittle. Used some tungston filled filament and accidently forgot to change my settings. Printed it with 1 shell and it crumbled like eggshell when I put any pressure on it.

But it sure looks good.

Walnut shells? I haven’t heard that one. That tumbles metal? Gonna have to give that a try.

Wow this is really cool. Thanks for sharing

It’s just for the look :wink:

But the Colorfabb filaments are not (much) weaker than regular PLA.

the nutshells make the surface smoother - in theory

I am not sure if this is really necessary. Sometimes things help, allthough they only exist in your imagination :wink:

I heard that any additive that disrupts the “plastic matrix” makes it weaker. So I would imagine that the metal powder just messes with the strength of the plastic. But it sure does look pretty!
