Unlike FDM 3D printers the customers needs play more of a factor with this technology. DLP tech is used for more complex designs , and higher resolution parts. It can also be used to produce small to medium lot runs as multiple copies can be printed at the same time.
This material is a bit more intense and is not as safe as most FDM materials when it comes to uncured resin in contact with the skin HOWEVER, a fully cured part is completely safe to hold and is 100% recyclable after use.
