Topic: SLA Post Print Cleaning Discussion

Would like to start discussing post print cleaning. The standard process is rinse in alcohol multiple times then air dry followed by your curing stage rather it be in a UV oven, Sterilizer, or in the sun.

I am looking to use alcohol in an ultrasonic cleaner to see if it works better or faster. I have also read a chemical that works as well and is safer than alcohol is called Yellow Magic 7. It is also supposed to be eco friendly and safe to dumb once strained.

I plan to use this with an ultrasonic cleaner as well. Has anyone tried this or alcohol with an ultrasonic cleaner yet?

Printing since 2009 and still love it!

Re: SLA Post Print Cleaning Discussion

well I don't like yellow magic 7 as a cleaner for parts.

All of the parts I have used with it never fully cure. I will stick to IPA.

How are you disposing of the IPA that is contaminated by resin?

Re: SLA Post Print Cleaning Discussion

I don't know about Mark, but I take the IPA tub, and put it outside in the sun for a couple of days. 

The liquid will turn to jello.  You can then take it out of the tub, and break it up into small pieces to cure it further. 

If you just leave it in the tub, it won't harden, as there just too much IPA still trapped inside the Jello.  It need to be broken up into small pieces to fully cure.

To print or, 3D print, that is the question...

I actually do the same I have a big clear plastic bin (I ate the red vines and kept the plastic bin the red vines came in)

it solidifies in there and after a few days its hard and I can pop it out and toss it in the rubbish bin.

Re: SLA Post Print Cleaning Discussion

I would think it would be easy enough to cobble up a simple still to recover most of the IPA . Solvent recovery distillation is fairly common in industry.

Well one would not want to drink the stuff .

a distillation unit is simple a heat source to cause evaporation . A cool surface to condense the material and a way of collecting the condensate.
This was designed for water but I think it would work for recycling IPA.

One could even do this survival style with a piece of plastic sheet a small rock and a tin can
