I've seen several parts produced by a 3D raster printing device that contain
complex surfaces and very fine detailed features. Plus, the surface finish is
excellent. Al: These parts just might knock your socks off. It may be a
little dangerous to conclude that 3D raster devices can only produce blocks.
As for speed, brace yourself because you may be in for a surprise. And over
time, the speed of the process is likely to improve. Dick Newton mentioned
that the market will decide whether the raster approach has merit. I believe
it does.
