Advise on Dremel accessories for polishing & abrading 3D printed objects?

[kolvenbag 1]

I am looking for selecting the right Dremel accessories for:

 

• Abrading
  
• Polishing
  

Mainly with PLA and ABS printed objects.

If you have any experience, please advise me what accessories work best.

I have a Dremel 8200 set.

PLA only. You need to be careful with a Dremel as it will generate heat. I have only used a Dremel once, with the paper based abrading insert on a surface that had support scarring. It certainly smoothed the surface (required) but the end result was not pretty (not a problem).

I use one technique which gives excellent results. Typical reason would be to smooth off artefacts from corners. I use very high grade files, from the jewellery industry, and lightly, and I do mean lightly, file them off. This will depend on the filament but using black PLA as an example - the filing will remove the sheen from the plastic. I then apply with a rag some Baby oil over the area which makes it nice and shiny again.

I do hand work with wet and dry (wet it!) - the dremel was just heating the plastic (PLA)

I was thinking of using a dremel on bronzefill, but it's not really working as well as hand polishing.

The thumbler idea seems interesting though!
