Pixel Sweeping Technology enabling 3D Printing of Large-Scale Objects with Delicate Details

摘要

Stereolithography based 3D printing is widely used in both industrial and consumer market due to the high precision and printing speed. On the other hand, customers and industry manufacturers desire a high performance technique that can enable the direct fabrication of integrated large-scale objects with delicate details in a fast speed. We have developed a pixel sweeping 3D printing technique that allows the UV projector continuously cures the resin when scanning over the build area to print large objects with delicate details. This scalable 3D printing technology enables the customized build volume in large-scale (can be even larger than 1 m~3), while remains the micro-scale features and smooth finish. Our 3D printing technique with the ability in large-scale fabrication and volume production is expected to provide ideal solutions in medical, dental, jewelry, automotive, and aerospace industries.
