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 with B9 cherry. My projector is Vivitek D555.
Can anyone help me? what is wrong with my projector?

Re: Vivitek for B9 cherry
How far away is your projector from the resin? How well did the EC500 cure at that distance?

Re: Vivitek for B9 cherry
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?
Re: Vivitek for B9 cherry
It's possible. How long are you exposing the B9 to your light source? How far away is the projector from the vat?

Re: Vivitek for B9 cherry
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 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.

Remove the UV filter from the lamp.

Re: Vivitek for B9 cherry
With the b9 cherry you are going to need to remove the UV filter from the projector bulb.

Re: Vivitek for B9 cherry
Once I removed the uv filter from a vivitek projector and the projector burned. I'm a little worried to do this again.
