I used brass screws, works fine.

These aren’t full metal Marvins if they are printed with ’ -fill’ materials. They are mega-cool though!
How long did you leave them in the tumbler? Any other details? They look awesome!
Are metal “fill” materials abrasive? Has printing with this worn down your nozzle at all?
I didn’t recognize any effect to the nozzle yet. May be it’s because I didn’t print much more than theese three
little guys until now
approx. 12 hours in the tumbler and then approx. 20 minutes of polishing with the buff wheel for each Marvin
I’m just assuming it was a typo when the word ‘full’ was used. Perhaps it was meant to be an ‘i’ and not a ‘u’. Will be posting a truly fUll metal Marvin in stainless steel soon ; )
I have been experimenting with these filaments, but not without some problems. Could you please give your print settings, like temp and nozzle size.
As a chemical bio physics engineer I am now trying polishing with chemicals. NaOH gives promising Results. Only have to find the right concentration.
Nice!! Looking forward to see it!
Wow those are awesome. I was proud of mine here but these have such nice gloss. Did you use a buffing agent?
Really captures the true colors of the metals.
Great work!
Hi, thanks. What do you mean with buffing agent?
Wow. Yours look super awesome as well!
Pretty much just a polish (example: http://www.instructables.com/id/Polishing-Badly-Tarnished-Brass/step2/Tools-and-Materials/ ) but some go very well with good buffer with micro-abrasives. Still trying to figure out the good shine. I just put this post up but its still not vibrant shine like yours. I think i just need to be more patient in the tumbler…lol Talk Manufacturing | Hubs

@Amortech : Your prints re looking really good too
I used a buffing wheel with micro abrasives in the last step.
Your are right patience is the most important thing with the tumbler. But the best thing is that you have to do nothing but wait
Also different abrasives in the tumbler are making real sense.
May be we should put our knowledge together and write “the ultimate colorfabb metalfil filament polishing guide”?
Hi all. Very nice Marvins…nice post. I’ve my own pre-polish Marvins…lol 0,1mm layers, 205*C , and 24mm/s Those are made at a Hephestos with a 0,4mm nozzle. Best regards.

cool! +1
The Hephestos seems to be a good printer for the money. Are you satisfied with it?
Cheers,

It’s a fun 3D printer to deal with. The extruder and hotend works very good…and gives no problems with the parameters. Just now I finish a filaflex print without problems. Highly recommended printer to understand the 3D world. Best regards.
