3D printed pens created using the Figure 4 DLP 3D printer to deliver finished parts in 3 minutes average time and at very high accuracy

What’s driving the excitement about DLP and other pixel-based additive manufacturing approaches? Speed. With DLP there is almost no correlation between cross-sectional complexity with productivity. While with vector-based additive approaches there is a significant correlation: - the more parts you have in batch the longer the build times. To demonstrate this difference we are presenting “The Three Minute Pen” at Rapid+TCT 2019 event in Detroit this week. On a vector-based system this plastic pen would be called the “30 to 55 Minute Pen” while on the DLP-based hardware this is called the “3 Minute Pen”. This is why we selected DLP to drive the engines within our Figure 4 production systems. Productivity matters. 

Each pen was finished with inlaid acrylate paint for a perfect finish

The pens are printed in a batch process, and after curing are then finished with a novel recessed inlay acrylate paint for that final perfect touch.
