Build Your Own SLA/SLS

I am also working on 3D printable general purpose parametric VAT.

Hi Drago, thank you.

Could you please elaborate more on how the mirror can be used to adjust distortion?

An update after a long time - this is how the frame looks right now. In the bottom part you can see the projector with my own electronics driving the galvos and stepper. SLx_frame.jpg And this is one of first test objects - not very clean, but it works: SLx_test_object_2a.jpg SLx_test_object_2b.jpg ...

Drago, great news! Does it mean that you are ready to sell samples?

ciclopez: Thanks for the info regarding TMC429. It seems that this chip is what I was looking for. Already ordered 1pcs in SOP24 package for prototyping and 2pcs in QFN32 package. I would probably prefer QFN32 for production as only this version offers 2 switch inputs per all 3 steppers. Do you have...

Nice job! Let us know how it is performing. I am working on something similar, however for galvo-based SLA/SLS systems. I am currently building first prototype - galvo control part is working, stepper and end-stop part is completely missing :) It is running on my own cloud-based software. This is a ...

Hi, I found several references of this technology inl this forum. What is your opinion - is it feasable to make it working DIY way? In my opinion, scanning over the same/partly overlaping area with two galvo systems is not problematic. What I am affraid of is construction of femtosecond laser source...

Drago, could you please publish some testing results for PP foil?
Thnx.

Drago, what was the issue during the process of sheet manufacturing?

PacManFan, I just checked Lasershark behavior with different galvo + driver set. Unfortunately without any change, the distortion and noises are still present...
