Tumbler for 3D Metal Print

Recommended Posts

I am using colorFabb's copper, brass & bronze fill to produce the best polish for a jewelry piece. Wanted your advice on which tumbler would work best. Thanks..!

They look metallic, but is the filament strong enough to make gears for motors? If not, can someone suggest a strong filament that produces gears (that won't lose teeth)? My gears are 1 cm diametre with 20 teeth and need to be rotated to lift heavy objects. Steel is what the gears are typically made from.

Guys Hi

how are we getting on with the Tumblers, I looked at the Amazon ones but I'm in the uk so I think AC might be a problem, does anyone know if they are 110/240v AC..

onkelgeorge

what are you using for the abrasive, I looked on Thingiverse looked good how long did it take to get a finish like your pics.

Being AC motors both frequency and voltage is somewhat critical, and using a transformer or switcher will cause problems. I doubt you will find some with dual voltage (in that case you should be very careful with the quality). I would buy it from Europe or domestic or another country where 220-240V 50Hz is the norm, unless they specifically offers these voltages/frequencies.

I use this one:

It has selectable speed, and timing. I use inox balls 1.5mm. Have tried brass screws too but with average results. I am able to get shinny parts in about 2 hours at medium tumbler speed.

I have used colorfabb brassfil, copperfill and bronzefill, and all them are very brittle. Not suitable for any significant mechanical effort, IMHO. Have you tried Nylon?

I saw a wile back that the guys at Adafruit.com have done tumbling and put up a guide: https://learn.adafruit.com/copperfill-filament/

See the Usage and Tips pages.

It seems they also made their own tumbler: https://blog.adafruit.com/2015/07/16/affordable-rock-tumbler-3dthursday-3dprinting/

I have not tried any of this yet, but I hope this helps. :)

Can a cheap quiet tumbler be made with a cheap stepper motor or something small of eBay, I don't really want to spent much making one or care how ugly it looks just a motor a cylinder and the stand?

I have zero experience in connecting it to any power but surely there must be a way.

I'm also in the UK so if anyone else is interested it would be great to do it and share our problems and solutions!

If you could provide what to get and how to connect it to the mains via any method i could follow, id have no issues in putting it all together!

cheapest one on eBay is like 60 quid, but i think thats bit steep, even though I spend that on a night out! lol. but it seems limited and Id like to increase the capacity vastly to spin 20cmx20cmx20cm objects with sand or fine abrasive materials rather than full on rust removal. and would like to design a single rotating bar design which i could in theory rest any size drum on with rubber bands around it or something.

Any ideas? I could draw my idea if it helps?

I will receive a rock tumbler for my birhday, in a few days. I would like to use it to polish some prints in brassfill.

The picture shows 2 prints (with an Ultimaker 3) with brassfill manually polished with sandpaper. The result is far from perfect. bumba_brass.thumb.jpg.259371d7649dca8b0273c8e5da640dd7.jpg

I read about tumbling with screws, inox balls and grit. From your experience, which method is the best? What'se the best way to use those methods?

I use several brass wood screws from Lowe’s.Colorfabb has a good tutorial someplace on their site.At the minimum,it should be like 3-5 sizes.I leave mine overnight,depending on what I need.

Thanks for the information.

I also saw this video:

from Adafruit Insdustries

 

Can't wait for my tumbler to try 😉

      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
