Create Perfect 3D Resin Prints by Finding the Optimal Layer Exposure Time
Full article with all STL Files - https://core-electronics.com.au/tutorials/perfect-resin-print-exposure-setting.html
Understanding exposure test models means you can nail the exposure time for your printer-resin combo. This is the secret to producing crispy 3D prints that capture every single detail of the original design. This is the Fourth Episode in our Resin Printing Series.

Layer Exposure Time determines the light exposure duration for a single layer of an object that you are trying to print. Unlike filament printing (where it can feel like there is an almost endless amount of settings that you must know about for perfect 3D prints) resin 3D printing has much simpler dials to adjust up and down. And the most crucial dial is Layer Exposure Time and its wrong adjustment is one of the major reasons why resin 3D prints fail. It is all about finding that sweet spot. The best way to test for and find the correct Layer Exposure Time for your set-up is to print a couple of exposure test models with your Resin 3D printer at different exposure amounts. You can adjust the exposure settings directly through your 3D resin printer user interface (UI) or in your slicing software. Under-exposing or over-exposing can really cause havoc with the resin printing experience. Too long exposure will result in light bleeding and scattering deep through the resin material resulting in a loss of intricate details and dimensional inaccuracy. Too short an exposure will create an under-cure result. Under-curing can be identified by several factors such as layer de-laminations in the middle of the part, serious loss or miniaturisation of intricate details, general poor model adhesion to the build plate, or the worst, the entire model falling off the build platform. Bottoms layers are the first few layers that are exposed to UV light in your model and bottom layer exposure times are always longer than normal layers exposure times. They are exposed longer so that the model can adhere more securely to the build platform.
As a general rule for Normal Layer Exposure Time use 0.5-5 seconds for Monochrome Screen Printers and 2-20 seconds for RGB Screen Printers. Another good rule of thumb to follow is to set the Bottom Layer Exposure Time to be 8-12 times longer than the Normal Layer Exposure Time. This is a good generally but make sure to keep the bottom exposure time lower than ~30 seconds.
