This is a pre-owned Formlabs resin cartridge in the V4 Clear type. It is compatible with Formlabs 3D printers and is ideal for creating clear and transparent 3D prints. The cartridge is in good working condition and may have some leftover resin in it.

The resin cartridge is suitable for use in various settings, including educational and professional environments. It is perfect for creating prototypes, models, and other 3D printed objects. Please note that this item does not come with a guarantee or warranty.

I got these in part of a 3D printer lot. I have no idea what was or is in these.
