A new method of making 3-D objects by stereolithography is proposed. To reduce the cost and the size of the system, a short arc discharge lamp is used as a light source instead of the UV laser. To make the fabrication time shorter, multiple spots ...
In conventional stereolithography methods, the solidified photopolymer layers are stacked one by one in resin. As a result, these methods have such disadvantages as time consumption to recoat new resin layer and to remove the surface roughness cau...
