Acetone vapor polishing

I think I would like to collaborate on that. I can help with the experimental design, writeup, and printing/polishing samples. Maybe we can get a few different people printing samples to incude as a variable?

If you factor in the extreme lack of process control and/or quality management that seems to be the case with most filament suppliers (I've only seen one spool that even has a lot#), I think it can actually turn into an enormous experiment to get really meaningful results, so maybe it would make sense to try and identify some others who have access to test equipment as well, although the we'd have to start out with some kind of a small validation to tell us that the different testers give us the same results.

Did you just do tensile dogbone testing or something more exotic?

 

Also, what do you use as your method for DMC? I only expose to the acetone for a few seconds. I've been told that you also only want a few second of exposure with the DMC, but that it is difficult getting your whole part. I.e. if you have deep narrow features, by the time you hit the inside of those features, you've started melting the outside.

 

Started a separate thread under projects to continue discussion around testing.
