Hey dudes,

I'm working on building an SLA printer, and I've found one method of printing using an LCD screen in the same way you would use a projector in a DLP printer (Projecting the image of the layer beneath the resin), This method seems effective, in the very few videos that it is displayed and uses photo-polymers instead of UV resins. And that is my question, this method seems rather inexpensive for an SLA printer, but there must be something i'm missing, what are the draw backs to this method that I'm missing, and why is this method not more common?

Thanks!
