Project TitleNovel 3D Printing Method for Fast Curing and Building
Track CodeUIC-2016-061
Short Description

Researchers at UIC have developed a method for vastly improved curing and build times in 3D printing applications—even in building wide cross-sectioned solid objects, unlike the current fast-build method, CLIP.


3D printing has been a popular method to create prototypes and is becoming an affordable method of manufacturing custom consumer goods. Historically, the most common method of 3D printing is Fused Deposition Modeling (FDM), where a thermoplastic filament is heated to its melting point and extruded layer by layer to create an object. However, because of its time consuming nature, another method known as Continuous Liquid Interphase Printing (CLIP) has been developed, which uses UV light to trigger and oxygen to inhibit photo polymerization. Yet while CLIP decreases build time, it is not suitable for building wide-cross sectioned solid objects. To achieve wide solid cross sections, the resin has to “travel” a considerable distance without polymerizing too quickly. Therefore, researchers at UIC have developed a system consisting of an oxygen-permeable window textured with micro-holed patterns to accelerate resin flow. The oxygen-permeable window not only maintains a consistent liquid interface that replenishes resin, but a surface texturing further creating a pressure gradient to enhance resin flow. Additionally, the system includes a gradient light projection technique that can prevent any non-uniformity of the cured photo-polymer. This apparatus enables continuous 3D printing of multiscale objects with various geometries in meter per hour speed.

Applications:  Can be used in Continuous 3D printing technology to improve accuracy and reliability.

Benefits:  The system improves uniformity of builds, reduces the build time, and improves accuracy of the resulting 3D component.
