First ugly prototype
VAT with integrated Z axis with constant speed. I will rebuild it with stepper motor because there are some problems with the Z resolution and I will can use CW. Bottom-up

Re: All in one
Nothing complicated. My dream is to make the SLA printing accessible for everyone and to remove deficiencies. What does it mean? Low cost and high speed. I think I did it. The material was only the way to achieve this. I'm really sorry that the fep film does not work in this technology to be more accessible. Special thanks to Phife who made things possible and thank you that showed me some mistakes.

Re: All in one
First test of the new Z axis with stepper motor. Successful.

Re: All in one
My prototype is ready. The new Z axis works perfectly. In the video I test the speed of the peeling with continuous light from 20W 405nm diode. 0,1mm Z resolution. All this for less than $150

Re: All in one
This is a very interesting design! Sometimes great genius lies in the simplicity of the solution.

Re: All in one
Wow. That's an innovative design!
I wonder if it would be beneficial to have two of the non-captive steppers (one for each side of the platform). From the pictures, correct me if I'm wrong, it looks like you've flattened the lead screw so that its rotation can be restricted, which could cause additional wear on the machine. Having one actuator each side could allow for a square build platform, active tilt for separation and no need to flatten the lead screw (as the end would be held by the platform). The main disadvantage I see is that it requires an additional stepper motor and driver, adding an extra $40 or so to the design.
Please don't take my thoughts as criticism. This looks like a fantastic concept and I can see that, combined with dragokirov vat material, could be an amazing revolution in consumer 3d printing. If only we could get a custom UV DLP projector for cheap, we could be set for an amazing device for under $1k.
