The 3d brokerage industry is at a crossroads. Maturity and tapering of the traditional sub-markets including Graphic Artist, Fine Artist, Commercial Advertising, and Social Media consumer combined with an abundance ready stock art is throttling demand. 

The brokerage that embraces and fosters the demand for 3d real time publishing will catch the next wave and dominate the field as demand surges. You have FB aquiring virtual goggle technology. Even Windows Phone now includes 3d webgl.  A.D.'s free Character Generator and the free fbx converter.  Adobe's HTML5 & 3d PDF.  Free or low cost R/T publishing apps like CopperCube, Paper3d, Goo, SceneJS, CopperLicht, SimLab3d and BabylonJS all make it so easy.  

Surge for 3D Printing will follow however its likely not as we thought.  I think the surge in demand by the 3d printing market for "models and representitive prototypes" will be short lived if at all.  Ultimately that market will be small and no store is properly set up to for captiolizing on the future of 3d printing today, IMO.  This is because the surge for 3d printing demand will be of licensed intellectuall property design with functional capability.   In otherwords we will be printing functional durable and consumable items.  The demand for models will be relegated to the hobby and craft niche which is where we are at with styrene plastic models.  Most may not be aware that styrene models can be made at home today from stratch using sheet and wood press molds to better effect than 3d printed models today. ...Point is few care and ultimately once the novelty wears of few will. * Therefore I think the focus for the future of 3d mesh and texture brokering for art will largely still be for 2d and 3d rendering in the visual rather than tangible medium.*

Hope this gives some food for thought on the subject :)
