The first imaging compon- 154 - 2-, ent may be a programmable planar light source or a spe- ''''` ' cialized refractive rastering mechanism, or other imaging system. The platform includes an infusion system for providing photocurab!e resin to the component being 156 158— . built. The object may be a powder composite component using any of a variety of powder materials or a plastic component. )-- , 1 ; .. '• / 11 150 7r M 160 71' IN Figure 1 71' 162 11 IN 11 © ei O
