Abstract

Additive manufacturing of polymer parts via photpolymerization has emerged as versatile production technology. Toolless fabrication of arbitrarily shaped 3D printed parts has shown promise for industrial application, especially when processing high viscosity resins which lead to polymers with enhanced thermomechanical properties. However, until recently these production machines were limited by both field of view and light sources capable of providing sufficient energy density. With the advent of scrolling DLP projectors, high throughput systems could be conceived. By precise signal control and image plane matching, a novel additive manufacturing platform was developed. A pixel pitch of 50 µm is maintained over a printbed of up to 1 m x 0.28 m. It is capable of processing high viscosity resins at a throughput rate increased by over a magnitude compared to conventional Hot Lithography printers, enabling industrial scale production of high performance polymer parts.
