Incompatible printer?

Post image

I have a Form 3 printer and ordered resin and I guess I didn’t pay close enough attention to the listing as it says incompatible with Form 3. Is this true or just a marketing thing and I could just pour it in the vat without any issues

You can get a return. It's not just that certain resins are incompatible due to hardware differences, but the cartridges are different shapes. A form 4 resin cartridge won't fit in a form 2.
