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?

This is very interesting application for precision work. I wish more local vendors have this capability.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
