Pegasus PDMS replacement

[chooch]

I think I may have stumbled upon it from there info graphic: http://www.nexa3d.com/lspc-technology/

clear silicone oil must be what they use... it will still bind with oxygen keeping the band gap so resin won't cure to the tank.

I just so happen to have some clear silicone oil laying around.... hmmmm

Well that was a quick test... I used 40 weight clear silicone oil put it in a tiny clear spoon then put a few drops of resin on top.

First thing I noticed, the resin was more dense so it sank to the bottom of the spoon.

Then I took it outside for curing and it cured within seconds.

So that's not the wonder material.

Tried it on some PDMS too, no appreciably difference in regular PDMS and silicone impregnated. They both seamed to release with ease.

So we need to find something cheap, clear, more dense than resin and oxygen permeable.

I chased a few of the links from the site you provided. Three 0.75 liter resin container and three self-lubricating films for three hundred euros. Resin is clearly a consumable, but the self-lubricating film, quantity three also sounds like it's not everlasting.

There are other SLA and DLP type printers "out there" that use saline solution as the release agent. More accurately, of course, the carrier, as it never has to release during the creation. Most of the saline types I've seen are bottom up builders, while the Nexa appear bottom down (upside down) builders.

If/when I receive the breakable glass from the land down under, I'll have material to test. Cheap at first, no, but long life makes lower cost overall. Of course, it would be even better to have a printer ready to accept the stuff. The two resin printers I have are yet in the original boxes. My reading of these printers was so demoralizing that I originally planned to sell them in as-new condition and take a loss. With the breakable glass possibility, the printer may become a viable working device.

With your work as well, it becomes (or will become) even more flexible.
