Vat separation mechanism

Peichao Wang I would like to propose an idea that I believe would make the separation from the Vat easier.
It is a mechanism composed of a spring (which can be registered more or less hardness).
Useful especially in the printing of large surfaces.
When the plate is lifted, drag the tray with it, at the same time the air penetrates under the Fep film, eliminating the vacuum effect between the LCD panel and the film.
The spring will then push the tray into the rest position

Thank you for your creative idea!

I am the mechanical engineer in UNIZ. Your idea do help to decrease the separating force between vat and the printed layer in theory. Do you think the vat is stiff or flexible? If it is stiff, it really helps. But in fact the film under the vat is flexible, and the fixing structure for building platform is cantilever. So in real printing, the peeling is from the rear to front. These two factor do a lot of help to peeling.

Besides, if you set the parameter of ‘motor heigh’ smaller than the distance the vat can move. The print will fail.

Hope it can help you! Thanks again for share your idea!

I find a bit of a simple thank you from a company! I believe that Andreas should be gratified in some way by the company for the idea! This helps the company and slash users!

my proposal was designed for the use of the current rigid tank supplied with the Slash, the motor that drives the tilting movement is the lifting plate, the spring is used to position the tray in the rest position.
As for the lifting stroke, just add a limit switch device

Kudos3D uses what they call a Flex vat with 2 hard and 2 flexible side walls. They use this vat for their Titan 1&2 DLP printers and also the new Bean printer. I’ve been to their office and tried out their printers before. Works great and no mechanism needed because on end of the vat is locked in and it flexes once the lift starts.
