Hello! This feature is actually already available for free on Formlabs SLA printers, through the Print Settings Editor (PSE) in PreForm. This tool allows users to adjust print parameters, including the early layer “elephant footing” offset you’re experiencing.
You can fine-tune this by going into the Early Layer Exposure and Offset section of the Print Settings Editor and adjusting the first layer’s offset value. In the example for Grey V5 on Form 4 at 0.1mm layer height, by default, the offset is set to -0.3 mm for the first layer. Making that more negative will increase adhesion but may worsen the flashing or elephant foot you’re describing, essentially creating a “brim,” like in FDM printing, increasing adhesion but potentially increasing the flashing effect. Adjusting it towards a more positive value will reduce the offset, making the elephant foot smaller, which is what I think you’re trying to achieve. You can experiment with this value and see if there is any tradeoff to layer adhesion for your specific use-case.
I would recommend changing early layer offset for the first few layers if you want to eliminate flash.
for example,
+1
+.5
+.3
