I use the B9 Creator V1.1, 50µm/25µm (x/y - z axes). I am using red resin (the cheapest) and it works great. Casting relyes more on the “air flow” you have to provide to your klin (in case you have an electric klin), therefore some people have added air vents to their klins… In case you have an older oven like those using LP Gas you won’t have any troubles.
Most printers have already a casting resin, you have to look at their support forums so you can see what other people are saying about resins, casting issues, etc.
B9 Creator has developed some many other resins as well based on their new versions of printers and also with how fast or accurate you want to print. I do not know other printers but they seem to use laser beams, it seems they do not have any trouble with that. I prefer digital light projection technology which is more accurate on their XY definition. Hope this helps.
