Elastic 50A bubbles & frothing during mixing

Posting this here in case it can help others in the future.

The mixer on our Form 4L moves so fast that it really whips up Elastic 50A in the tank. This introduces a LOT of bubbles and froths it up. Surprisingly this doesn’t introduce part failures, but it ends up trapping bubbles inside the part, which end up making parts less optically clear.


The solution to this is to lower your wiper speeds. Below on the left is with Default settings, and on the right is with the wiper speed halved. There are still bubbles during mixing, but it’s significantly better without compromising speed too much. I know bubbles can probably be eliminated entirely if you lower the speed further.

Hope this helps someone out there who encounters this like I did!

Cheers.

This works for making the clear resin just a bit more clear as well.

Interesting! I haven’t noticed any problems with Clear V5, but perhaps I’ll lower the mixing speed a little on it anyway.

It’s mostly me being very pick. We sometimes need to polish to a mirror shine and any bubbles fill with the polishing media and really stand out.

Do you mind sharing what you changed your speeds to?

Changed wipe speed from 600mm to 100. I might be able to increase it a bit, but it was only for a couple prints, so I haven’t really done extensive testing yet.

Got it - thanks!
