Hi,


Cool machine!


This is my first post on this forum...i thought this might be usefull in your process.
i think the sanding part is a waiste of your time, not good for your hands and everybody hates sanding i think..


Iff a polis or sand machine will melt it you could try this:

i know allot of hardware stuff and toys and car parts are polished by simply throw it in a bucket with the right material and it get polished by movement, you just need to find out what polish your printed material the best...


Also works on aluminium
it will never melt your product as it never heats up
And you can polish a few machines at a time

one material at a time


You could try:
#Glas marbles
#Hardend bearings
#nuts
#your toe nails
#whatever


A small cement/concreed mixer you see used by construction workers will do the trick for sure you can find these cheap.
they are pretty quiet acctually iff kept clean and lubed.


You can make a cover on top of the bucket and the noise should be minimal.


or you could just expiriment with a plastic bucket with a cover with a material and shake it
I hope i picked the right words as my english is not that good

Funny you should mention that!
Because I experimented with tumbling just a couple a weeks ago!

But the thing is, when a print is finished, you´ll have a pretty rough surface, way more that say e.g molds. I could print in a higher resolution, almost 3times better than what I print now, but that would take ages.
It´s faster to file, sand and polish, and now I finally got the hang of it!
Polishing works fine if I move the part around a bit more than metals, it just takes a bit longer to get the "glassy" feel to it.

In the future I´ll invest/or make a tumbler for polishing small parts, but first an upgraded 3Dprinter is on the top of the list!

I also experimented with some carvings, looks like I can do something custom with that.
