Final Cleaning of PLA

Recommended Posts

Here's a handy hint I've been meaning to post for ages; if you have a PLA print that's been discolored by sanding and post-processing, rubbing it with a little mineral oil does wonders to restore the color and give the print a nice sheen. Doesn't seem to do any long term harm, and the effect lasts (at least I have some pieces on my desk that I oiled months ago, and they still look great!)

I use some food safe mineral oil intended for sealing wooden cutting boards (coz that's what I happen to have lying around at home).

Morag - the fbrc8 Thingalump

It's worked with several different PLA's from different manufacturers - but really brings out the best from metallic plastics!

Specifically, I used this:


I have no idea if it works, but it seems Baby Oil might work just as well (and make the print smell nice :-) )

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
