摘要: A method for producing an implant blank (100), in particular a dental implant blank from a starting body, said implant blank (100) comprising at least one first area, which is a surface area (102), and a second area, which is a core area (101), wherein the surface area (102) has at least one bioactive surface material (502) and extends from at least one first surface (103) in the direction of the core area (101), and the core area (101) has at least one carrier material that can be subjected to mechanical load. The starting body has a porosity for controlling a targeted distribution of the bioactive surface material (502) within the starting body and is loaded with a solution (500) of the bioactive surface material (502) in a first step, which is a loading step. In a second step, which is a distribution control step, the distribution of the bioactive surface material (502) within the starting body is controlled such that the solution (500) has a higher concentration within the surface area (102) than within the core area (101), the control being effected by regulating one or more environmental parameters in a closed environment (200), in particular by regulating the humidity and/or the pressure and/or the temperature.

摘要: Systems, methods, components, and materials are disclosed for stereolithographic fabrication of three-dimensional, dense objects. A resin including a first binder, a second binder, and dispersed particles can be exposed an activation light source to cure at least one of the binders in a layer-by-layer process to form a green object including the first binder, the second binder, and the particles. A dense object, such as a metal object, a ceramic object, or a combination thereof, can be formed from the green object by thermally processing the particles and removing the first binder through a primary debinding process, removing the second binder through a secondary debinding process different from the primary debinding process.

摘要: A luminescent coating is disclosed that is used to dimensionally control the curing of a photocurable agent placed in close contact with the coating. The coating is applied at the interface of structures, such as brackets and prosthetics, or may be applied directly on a curable material for use in 3D printing, at the location where bonding material is needed to be cured. The luminescent coating irradiates from its structure the curing radiations necessary to photopolymerize the resin in response to a first radiation irradiated on its structure of a different wavelength.
