3D Printing Process: Figure 4 DLP
The Figure 4 DLP technology from 3D Systems is similar to SLA 3D printing by curing UV resin with a laser. However the fundamental difference in build process between Figure 4 and other SLA technologies is that Figure 4 is a projection-based technology, whereas SLA is a laser vector-based technology. Because Figure 4 is projection-based, there is no time relationship between layer time and cross-sectional detail. Also, the Figure 4 build process, parts are built upside down, and the three-dimensional object is pulled upward from a membrane. With SLA, parts are built upright, submerged in a vat of fluid. Because Figure 4 parts are built on a non-contact membrane, there is no surface meniscus like you see with vat-based SLA, as such it is possible to achieve very thin layers. Combined with the projection process, print speeds with Figure 4 are also very high. In regards to post processing the Figure 4 DLP technology, there is no appreciable difference between that and finishing SLA parts.
