I've been bearish on 3D printing in the past. This particular device, it's intent and its manufacturer answer most of my criticisms of 3D printing hype. For starters, it's a stereolithographer, not an extruder, which means it'll work with a bunch of different materials. For another, it's an extension of a 3d language from the preeminent manufacturer of 3d software (I learned CAD on AutoCAD 4 in 1992). For yet another, it's priced in the same strata as existing large-format printers, typically used for engineering drawings by architects and engineers.
This device serves a very specific purpose - it will allow architects to print houses rather than assemble models by hand, and it will allow 3d artists to print characters and cars rather than sculpt them in clay. My main beef with most 3D printing discussion is it's a solution looking for a problem - Autodesk is coming at it from the exact opposite angle of an age-old problem that hasn't had a decent solution.
