Titan 1 does not use any magical technology. They have a simple vat flex-hinged on one side to have a self tilting mechanism. To gain extra speed they just give you the opportunity to speed up layers that have less suction issues then others. (I'm not sure even if it is autocratically done). You can look at a very detailed print video here:
Its very long, but you can skip parts and learn how they work.
And by the way, Their software is only for controlling the build. For slicing they use our beloved CreationWorkshop
Carbon 3D

Re: Carbon 3D
The Titan 1 is basically a flex vat variant. One side is fixed by a clip, and as the print is lifted this induces a peeling motion.

Re: Carbon 3D
Thats pretty much what we can see here:

BUT: Thats not continously like in the actual video and even if it would peel of at higher angles, that would require moving the build plate back down to the desired layer height.

Re: Carbon 3D
Yeah, we know. The Titan likely isn't as fast as the carbon3D, but it is a pretty damn fast printer.

Re: Carbon 3D
Here is an Idea I want to share of a way to speed up printing with standard vats:
1. use a passive tilting vat similar to titan-1 system, but instead of just resting on the base below, let it rest on an electric contact connected to one of the controller (arduino) inputs.
2. for every slice, project the image as usual, then slowly lift the platform. This should tilt the vat as usual due to the suction forces, but this time it will be detected by the firmware as the contact will break.
3. continue the lifting until the vat fully separates, and bounce back to place. This too will be detected by the controller, letting it know that no more lifting is needed, and the platform can retract fast back to the next layer height.
Using this system, the platform will rise only as little as needed. And no need to calculate rising height/time based on blob sizes. This of course might involve firmware/sw changes - but should not be that hard.
Of course, If a cheap permeable film will be found before I start working on this idea, I will ditch it in a sec...

Re: Carbon 3D
And the next one getting much faster:

@shaise
I´d rather go with an active peel mechanism like the guys an M-One did. Its faster and as you´re raising the build plate, you have an opposite movement which creates a larger distance.

Re: Carbon 3D
I spoke with Bo Pang, the University of Buffalo student whos using a membrane. He told me hes just using PDMS on his machine, so nothing really fancy, just a thin cast sheet of it.

Re: Carbon 3D
When I tried PDMS it was on a sheet of glass, so no oxygen could get to it. I was using a tilt release with no success. Perhaps if were able to make or get thin membranes of PDMS we could try it like a flex vat?
I think PDMS will still stretch a lot? Maybe that other Silicone membrane that had decent oxygen permeability would work better? Just stretch it a lot so its thin and very tight.
