Abstract
USC researchers have developed a novel additive manufacturing process called linear immersed sweeping accumulation (LISA). LISA utilizes a moving linear accumulation tool immersed in liquid resin to fabricate 3D objects. It offers a balance between speed and flexibility by using line segments as the basic accumulation element. The process incorporates 5-axis CNC motion, enabling concurrent resin curing and recoating. With its non-layer-based approach, LISA can fabricate large-volume 3D objects efficiently.
Benefit
-
Faster fabrication speed
-
Effective resin refilling
-
Improved layer separation
-
Large-volume fabrication capability
Market Application
Current additive manufacturing processes such as stereolithography rely on layer-based fabrication techniques. However, the recoating process between layers is time-consuming, accounting for 50-90% of total building time. If the recoating process is shortened or eliminated, fabrication speed could be dramatically increased
