Direct-Print Photopolymerization

Direct-Print Photopolymerization (DPP) is a 3D printing process, involving direct-print and direct-cure of a photopolymer at the same time. The advantages include shape retention of a deposited filament and broad range of a material.  This process enables the use of various viscoelastic and composite materials with applications of sensors and actuators.
