Abstract: The invention relates to a disposable 3D printer cartridge for inserting into an exposure device for producing an object which is constructed in additive layers, wherein the cartridge contains at least one polymerizable liquid, or a polymerizable liquid can be filled into the cartridge. The cartridge comprises: a first lower housing part, a second upper housing part which can be removed from the first housing part, a support platform which forms the lower face of the second housing part, the object constructed in additive layers being arrangeable on the exterior of the support platform during the construction of the object, and a construction element which corresponds to the base of the first housing part. The layers of the object can be polymerized on the inner face of the construction element, and the inner face of the construction element has a non-stick coating.
