UPDATE: UV Pass Filter DLP Projector Mod ~ How well did it work in my SLA Printer?

If you tried the UV pass filter mod and had trouble getting it to work this video should give you some comfort and offer up a few ideas on what to do next. This is as much a learning experience for as it is for you and thanks for taking the journey with me. I hope you enjoy the video and be sure to let me know what you though in the comments.

The principle behind this modification is that normally a DLP projector contains a "hot mirror" that blocks both UV and IR wavelengths. It does this to protect the rest of the optical components from the heat associated with IR light and the damaging high energy light associated with UV light. But unfortunately that tends to include wavelengths associated with curing resin such as 385nm or 405nm. Since these wavelengths are only near UV if the output of the projector is modified to include these wavelengths then the curing speed of a DLP printer can be greatly increased.

This concept was proven true in my previous video. However, due to some who have tried this modification themselves and failed I felt it necessary to investigate how well my modification has been holding up. Turns out its been both good and bad, and my efforts to correct the bad have so far turned out very bad haha. I'm all ears for recommendations so let me hear them in the comments.
