I noticed that that “high speed resin” was sold out even if they were still bundling it with new printers

Then I realized that the profile for that resin in their own official slicer had half the vertical resolution and half the exposure time. It’s something broken that they created just for allowing the marketing to say “the fastest printer on the market, full prints in 2 hours instead of 8”. Even the demo file that was given with the resin had layer delamination when printed, and that’s the best use case, an empty cylinder that needs no support and has a constant wall thickness all around

It was the resin. Once I bought a resin from another brand, it printed perfectly

It really puzzles me why they would bundle 2 kg of low quality “high speed” resin that isn’t even able to correctly print the test files…

the slicer said the model needed a repair (which it did), but then it also does this with other stuff. Later I try with a profile with more exposure time

first print with the printer and first print with resin in my life

The manual didn’t mention the exposure calibration at all…

visual inspection of test exposure is ok, and then the vat is brand new so the sheet was immaculate
