After a few weeks of using this printer and tested 2 differents resin, I can say in general that it´s a good quality printer for those who don't care about precise dimensions, especially at this price. The first models were made with fast UV curing resin like Ameralbs and for small pieces, the results were pretty good. For the largest parts, I could not find the best exposed times for good print quality. The second resin that I tested was Green translucid from Elegoo Mars. Even for the big models the only problems that I had were with the humidity in the ar and the correct dimensions. Here are the most important pros and cons: Pros: Good construct materials with ball linear rails and Air filter, the FAN helps to keep the temperature above 20 degrees, Uniform UV light source of 405nm with 8x Anti-aliasing and 2K LCD for highly-detailed prints, USB Pen with 2 big models and help PDF files. Cons: The perforated print plate didn't come with the printer (important for big parts) and could be a little higher, the Z-axis make some noise (needs to be lubricated), I have difficult to calibrate de UV light because in each time that I printed away from the center plate the dimensions of measure on the piece gives me around 0.3mm deviation compared with the original CAD model. If the FEP Film is in bad shape or it´s durty the problem is even bigger. I'm still finding the best rigid resin. With the USB Pen could exist some VIDEOS to explain the main tasks that you should do before printing. I installed a measure temperature indicator near to the resin tank to control the correct temperature for starting the print, which is very important for a nice and smooth printed. I added some Fotos of the pieces (Most of them printed with 50 micros). Please, don´t forget to share our experiences with other types of resin.
