Visually Clear Resin?

Postby james_lan » Mon Apr 20, 2015 9:40 am

I was wondering about a visually clear resin which would be suitable for lenses. I just wondered if anyone had seen one or if they were even possible (as some of the curing with most resins occurs a little above the visible cutoff at ~400nm).

There has been some success with the Form 1+
perhaps this will give you some clue.

Is there an Acrylic based resin which could be used to print clear lenses? I am planning to print clear material on a custom-built DLP equipment. I am also concerned about the projection to be used; the resolution of the projector (HD or 2K or 4K, 1-chip or 3-chip DMD, etc.), wavelength, power output and the focusing system!

dear james_lan,

we do provide a clear resin:

Of course you have to dial in your printer so you dont have too much light bleeding. But we are printing with an DLP (Acer) based and an Wanhao D7 pretty well. Of course UV Curing turns it yellowish (the reason, why so many resins are not clear but opaque) but we can provide you with the data needed for temperature curing.

Have a look on our specs: https://druckwege.de/wp-content/uploads/2017/08/Technical-Datasheet_TypD_English_v2.pdf
