Abstract: A cartridge (1) for a 3D printer, wherein the cartridge (1) has a nozzle or is designed in such a way that a predefined nozzle can be formed in the cartridge (1). The cartridge (1) contains a dental composite material, and the dental composite material comprises a curable, in particular a light-hardenable, matrix and only fillers having a maximum particle size of <5 ?m. The dental composite material has a viscosity, in a non-cured state, in the range of 1 to 10,000 Pa*s, preferably 10 to 2,000 Pa*s, more preferably between 50 to 800 Pa*s.

Abstract: A single-use cartridge (1) containing a photopolymer resin (2) for use in a method of additive manufacturing, in particular, by digital light processing (DLP) or stereolithography.

Abstract: A method for producing a dental restoration structure (1) that is to be individually manufactured by 3D printing. The method includes the following steps: i.) placing a substructure (2) in a 3D printer (3), in particular on a support plate (4); ii.) determining at least one of the form and/or the position of the substructure (2) in the 3D printer (3); iii.) comparing the determined form and/or position of the substructure (2) with 3D data of the dental restoration structure (1) to be individually manufactured; optional applying a connecting layer to the substructure (2) and/or conditioning the substructure (2); and iv.) applying material, in particular application of a composite material, on the substructure (2) in a 3D printing method such that the dental restoration structure (1) that is to be individually manufactured is obtained.

Abstract: A sleeve-like element (14) is arranged inside a hydraulic support element to secure against drainage. In axial direction, the sleeve-like inner element (14) bears a shoulder (13) of a piston (4), formed by a rolled-in step (12). In this manner, the inner element (14) can be secured while the piston (4) maintains a uniform wall thickness.
