Laminated Resin Printing (LRP) is a new type of 3D printing technology that enables cost-effective rapid prototyping of microstructures. Unlike existing 3D printing methods, LRP is based on microfabrication processes and materials, using modern dry film photoresists imaged by fast UV projection. Resist sheets are laminated together without the need for adhesives, to form fully polymerized multilayer structures with print densities of up to 100%. The high-performance dry films suffer no shrinkage or distortion and allow LRP to print 5 micron voxel resolution in X, Y and Z, and form structures as small as 50 microns. The prints are resistant to all known solvents, acids and bases, exhibit a continuous operating temperature range of -60 to + 200˚C, and a low storage modulus of 1 – 4 GPa, making them well-suited to microsensor devices. Unpatterned resin provides support enabling direct printing of overhangs, membranes and moving parts for microsensors. With the increasing demand for miniaturized devices that consume less resources, run on lower power and integrate easily into the environment, LRP provides a step change in Microscale 3D Printing. This new and versatile technology enables printing of standalone planar structures, structures on paper, fabric or PCB substrates, and miniature 3D devices.
