Re: Floating resin in Bottom Up setup

based on the data sheets provided, the density of the high viscosity silicone oil dpizzle posted would not work for this application.

Re: My DLPrint3r / Germany

Finhead, I thought your printer no longer used a tilt or slide. With the pillow vat or flex bottom vat or whatever it's called, do you still need an active or passive tilt?

Re: my DLP build

that passive release looks like it's working very well. This is the pillow vat design, correct?

Re: my top down build

Very cool!
What kind of system are you planning on using to keep resin height constant?

Re: Acetat membrane with a resin film recoater, eliminates v

If acetate works well as a release film it can be used as a cheap alternative in a vat design like the MiiCraft. I've also heard that LDPE works well in that setup. I'm mainly posting in the hopes that someone with a working setup can try. So far I've only experimented with top-down but would LOVE a...

Re: Foot in high heel - top down system

Thanks for the info so far!
Do you do anything special to handle displacement of the resin caused by the build platform?
Do you have any 'wiper' system/recoater blade for the meniscus?

Some images of your machine would be extremely helpful!

Optoma EP749

Seems like lumens and bulb wattage are comparable to others' builds. The cont...

Re: Foot in high heel - top down system

Do you have a build log or any additional info on your one-week-built printer? I'm in the process of designing my own top-down and would love to see other's successful examples!
Thanks!
