Looks like 3D printing continues to grow a lot and come down in price while going up in quality and options.

I like the idea of using lasers to create a more continuous part. Might also be able to remove a lot of the "blockiness" from some prints. Or, being able to print both a conductive material and a substrate at once with the Voxel8. Still a bit expensive, but promising.
