To help you figure out exposure settings for new resins, we made a video and Instructable that demonstrates how to generate a working curve from multiple exposure settings on a single slide.
A “working curve” describes the thickness to which a resin cures as a function of the light “dose” for a given light source. While this may sound unexciting, understanding this concept is key to understanding SLA and DLP 3D printing. With the working curve, one can quickly generate printing settings without a lot of testing. It also allows one to quantitatively compare the curing properties of one resin versus another.
