# Does the resin vary from a printer to another?

I am using a clear resin to print parts using a Formlabs printer. At the moment, I am using the resin from Formlab which comes in a cartridge that fits in the printer. However, I would like to move to a cheaper option if available. I would like to able to refill the cartridges that I have rather than buying a new cartridge.

Is it possible to buy some clear resin from an outer source or would that damage the printer?

I can see why you are looking for other resin options. One place I saw online has a 1 L FormLabs cartridge for \$150, when 500 mL on Amazon is usually between \$20-30. I've seen special resin, such as flexible, as high as \$60 for 500 mL and ABS-like resin for$40, though. Water washable resins seem to be in the \$40-50 range. There's also "natural" or plant based resin for about the same price as regular resin, but might have a different reaction to your tank. I'd assume that every brand of resin (except for the rebranded stuff) has their own chemical makeup besides the various types of resin, so you might have to some testing, although I realize that messing up a tank that's \$150 to replace is not exactly something you want to do every day.
