A three-dimensional (3-D) printer includes build and support material development stations positioned to transfer layers of build and support materials to an intermediate transfer surface. A platen having a flat surface is positioned to contact the intermediate transfer surface. The intermediate transfer surface transfers a layer of the build and support materials to the flat surface of the platen as the platen contacts one of the layers on the intermediate transfer surface. A dispenser is positioned to deposit a leveling material on the layer on the platen, and a mechanical planer is positioned to contact and level the leveling material on the layer on the platen to make the top of the leveling material parallel to the flat surface of the platen.

The invention relates to a method for manufacturing an equipment part, comprising the following steps: providing a substrate, an upper face of which includes a large main surface; providing a computer model comprising spatial coordinates of said main surface and a second portion of the equipment part; then additive manufacturing of the second portion from the main surface, so as to secure said main surface and said second portion; then cutting in a thickness of the substrate to obtain a thin plate including the main surface secured to the second portion of the equipment part.

A method and an apparatus of a powder bed fusion additive manufacturing system that enables a quick change in the optical beam delivery size and intensity across locations of a print surface for different powdered materials while ensuring high availability of the system. A dynamic optical assembly containing a set of lens assemblies of different magnification ratios and a mechanical assembly may change the magnification ratios as needed. The dynamic optical assembly may include a transitional and rotational position control of the optics to minimize variations of the optical beam sizes across the print surface.

A method for additive production of a component, which includes the additive construction of the component on a component platform having an opening, wherein, during the first part of the additive construction of the component an auxiliary structure is produced additively around the opening of the component platform. The method further includes the introduction of a device through the opening into a cavity defined by the auxiliary structure, wherein, during a second part of the additive construction, following the first part of the additive construction, properties of the component to be produced are influenced and/or measured by the device. A component is produced by the method and an apparatus for the additive production of the component, includes the component platform having the opening and the closure.

A cooling unit can be coupled to a build unit of a 3D printing system. The cooling unit comprises a cooling unit opening which is arranged to face a build unit opening when the cooling unit is coupled to the build unit to enable transfer of content from the build unit to the cooling unit. The cooling unit further comprises a self-locking latch mechanism to couple the cooling unit to the build unit such that the cooling unit opening faces the build unit opening.
