So I have this idea for a 3D printer on my mind that has been bothering me for a while now. I've done a lot of research and it seems possible but I want to get some expert advice.
I'm building an experiment that looks like the image attached. Basically, it's a clear container that contains a clear photopolymer with 2 or more laser projectors aimed towards the container. What I want to achieve is the solidification of the photopolymer at the points where 2 laser beams intersect, and if I play a specific video on the 2 or more projectors, hopefully, I can create a solid 3D object. I am not an expert by any means, I just have this idea and I want to try it out. How do you suggest I start? I kept the question as general as possible to let you know that everything in the experiment is flexible and can be modified.
Is this idea technically feasible? Can you suggest a clear Photopolymer solution that I can test with? What light frequency should I use?
hi Ahmed, you are describing stereolithography, I've seen this kind of 3D printer before (look at that video https://www.youtube.com/watch?v=b-sIcYo8isI)
Thanks for your response Zakaria Salmi, I believe that my design would lead to actual 3D printing rather than 2D Layering that we currently see on the market. Not sure it would work though :)
about that I was sure that i've had seen something similar to what you proposed,
look at that https://www.youtube.com/watch?v=OXIkTlTR0c4
Actually I don't know but they made a paper about it : https://advances.sciencemag.org/content/3/12/eaao5496
You might be able to find something interesting.

Carbon 3D uses a 2-step UV/Thermal monomer formulation.
