Here is my first print. It is a tire for an Opel Blitz. The printer is a Saturn 3 ultra. The resin is Sirata Tech (recommended by jknaus). The biggest learning curve is not the printer, but the slicer software. Lychee slicer has a unique way of choosing the resin. You can pick peoples recommendations that have worked for them. I did no calibration just right to print. I am very happy with it.
