I have not heard of any plans to make a lower speed DLP chip, and I'm not sure one would be that much cheaper. However, I know for a fact that TI will read your comment above, so thanks for at least putting the bug in their ear :)
Like everything electronic, prices plummet for products that enter mass production. Right now most applications are professional, but within the decade I predict that home-versions of 3-D printers will become affordable.
I love the idea of more precision in 3D printing, I wonder what the cost will be and when the hobbyist will be able to afford these systems, it could open up a whole new world for the basement tinkerer. I would love to be able to crank out a couple of plastic parts (even if it takes a few hours) at home; what a great improvement in options.
I would have thought that there would be benefits to a higher resolution but lower speed DLP chip for these applications, whereas it sounds as if TI are just using the same chip that is designed for TV/Video rate projectors. Does a 3d printer need to change image at 50+ frames per second? Would it benefit from a higher resolution?
