Header and Body 3


This invention provides an improved way for performing SLA 3D printing that produces objects of a finer quality more quickly in a more scalable manner. It uses a microdisplay to generate an image and an array lens that replicates the image to form a kaleidoscopic imaging pattern on a resin that forms the 3D printed object. The use of array-to-array imaging rather than one-to-one or one-to-array imaging introduces scalable printing at tens of centimeter2 scales without requiring specialized instruments such as scanning modules or mechanical stages. Projection-based SLA multiplies small feature sizes of several micrometers with a kaleidoscopic imaging system that reconstructs patterns over a large area.
