Following upon @Thomas_Sanladerer filament videos and discovering all the fuss about PLA, PETG, bla bla bla… here is just plain ABS and it’s usefulness. Its the spare keys for accordion that were lost who knows where. Anyways, just trying to show what can be done in 5minutes (per key)of your time, sand&buff and it’s like molded piece. Now show me someone that can to this with PLA OR PETG or similar material. All this being said, really wish Thomas did some testing with new generation of ABS, ASA, Zortrax`s Ultrat and similar materials. Oh @Daid_Braam this is one more reason 
You can do the same with PLA. Just use chloroform.
Or substitute MEK that works OK. Or just clear coat it if you used another material.
@Jorge_Robles @Mark_Tomlinson no chemical used here, just sandpaper and polishing paste.
Thanks, with results like that it inspires me to try it for myself on all the stuff I’ve printed.
What type of paste, still cant figure it out how you got that shiny effect, can you plz explain your process
@lightshadown first 240 grid sand paper, then scotch pad - super fine to remove some of the marks 240 left, than buff with a buffer or drill with buff on. Use stick or candle polish paste and buff till all the scratches sandpaper made are gone. Now use some gentle polishing paste and give it that extra shine, can do this last step by hand, no machine needed. Layers need to be sanded, buffing won’t remove them.
I get the impression ther are a lot more materials in the Filaween queue, so I wouldn’t worry yet that a particular type isn’t being represented.
Yeah, ABS sands really well. PLA can in theory also achieve the same results, but in practice it’s much harder because sanding PLA is slow going. I’ve been able to get very nice smooth flat surfaces by sanding a PLA block on a large piece of sandpaper, moving the part rather than the sandpaper. However, the time required makes the technique difficult to scale to hand-sanding irregular shapes.
It may be possible to use something like a Dremel on low speed with a sanding head on PLA, that would be too aggressive for ABS.
I use a Dremel on a very low speed with the abrasive buffs followed buy polishing pads + paste and can get a similar effect on PLA. It takes a long time though as push too hard or go too fast and it just melts.
“just use chloroform”? How are you still alive?
