Build Your Own SLA/SLS

Once I removed the uv filter from a vivitek projector and the projector burned. I'm a little worried to do this again.

I think the D555 lumens is 3500. I also tried different kind of vivitek even a 1080p vivitek projector. But I had no success. The B9 itself uses vivitek projectors.
Sorry I didn't understand your question.

I did the exposure for around 40 seconds to test. I told you I made the projector 100 microns and the distance is less than 30 cm.

I'm using 100 micron. I'm well aware of printing process and I get good results with other resins but amazingly my projector won't cure just B9 Cherry. I think the problem is about uv filters. Am I right?

Hi everyone I've made my own machine and bought some B9 cherry resin to test. Everything was alright and calibrated but I was really shocked that my projector couldn't cure the B9 cherry. I tested other kind of materials like EC500 from envisiontec. They are alright and I can work with them but not ...

I'm a little confused. If I use the raspberry pi do I also need an arduino to run the motors or the raspberry pi is enough.

Hi everyone. Does anyone know anything about spherical aberration. I've heard that some projectors don't suffer from it, vivitek is a good example I think. But now I've bought an acer and I'm really satisfied and different areas in the plate have different brightness. Is it possible that I modify it...

You mean you weren't able to use Raspberry pi or you mean a tablet is easier?
And can you tell me more details of how you use the tablet?

Hi everyone. I was really interested in make my printer to work offline. But i'm really noob in electronics. As I know you can do it with boards like raspberry pi. Is it really that hard to do so? I've seen many printers that use a raspberry pi and a small TFT screen that does everything. I've also ...

Hi
Thank you very much but I've seen this before. I need to replace the dc motor with a stepper one.
Again thank you for your reply.
