Abstract: This invention relates to a method for manufacturing a part of complex shape (3) by successive deposition of layers according to a technique of 3D additive printing and pressure sintering, comprising the following steps: an initial step of producing a model (1) from a material chosen from a porous or pulverulent material based on a metal alloy, a ceramic, a composite material and a lost material by formation of successive layers deposited according to the digitally controlled 3D additive printing technique, followed by a step of introducing a preform (1) made of porous or pulverulent material to be densified, derived from the model (1), into a mold (2) filled with a sacrificial porous or pulverulent material (13) in addition to the preform (1), the uniaxial densifying pressure sintering (10) then being applied to the mold (2) in order to form the part (3) which is finally extracted from the mold (2).

Abstract: Systems and methods for growing cells or cell sheets are described. The method may use biocompatible or food-safe materials. The method may allow for cell alignment. optionally in selected patterns, which may be produced by casting a membrane on a 3D printed mold. The method may include surface treatment of an elastomeric membrane. The method may allow for the reuse of the membranes by autoclaving and/or a washing step. The method may create multi-layer cell sheets with an extracellular matrix (ECM) created by the cells, which may be detached from the membrane. Optionally, the cells may be separated from the ECM.

Abstract: The present invention relates to gels and processes for making bundles of aligned ceramic nanofibers, ceramic nanostructures made by such processes, and methods of using such ceramic nanostructures. Such process is templated via block copolymer self-assembly but does not require any post processing thermal and/or solvent annealing steps. As a result, such process is significantly more efficient and scalable than other processes that are templated via block copolymer self-assembly. The resulting fibers are aligned according to the direction of deposition, making steps where individual fibers are bundled unnecessary.

Abstract: A method for preparing virtual build volumes for the manufacture of three-dimensional objects. The virtual build volume represents an actual build volume over which one or more objects are to be built. The method includes the steps of: (a) receiving one or more object models, the object model(s) defining the intended dimensions of each of the objects; (b) applying a transformation to an initial virtual build volume to create a reduced virtual build volume smaller than the virtual build volume; (c) positioning the object model(s) within the reduced virtual build volume; and (d) applying an inverse transformation to expand the reduced virtual build volume to create an expanded virtual build volume including expanded object model(s); wherein each of the expanded object model(s) is larger than the respective object model(s).

Abstract: Apparatus and methods for curing adhesives in a robotic assembly cell and evaluating the curing at a same time or in parallel are disclosed. An apparatus in accordance with an aspect of the present disclosure comprises a radiation source configured to emit radiation to cure an adhesive in a curing area during an assembly process, a radiation guide configured to transmit the radiation emitted from the radiation source to the curing area, and a sensor configured to measure a reflection of the transmitted radiation reflected off the curing area during the curing of the adhesive, wherein the sensor is positioned proximate to the radiation guide; and a controller configured to determine whether the measured reflection satisfies a threshold and, based on a determination that the measured reflection does not satisfy the threshold, to signal a remedial action of the assembly process.

Abstract: A method of producing a component for a technical device which has a base structure and one or more supplemental structures. The base structure is not additively manufactured, the one or more supplemental structures is/are applied onto the base structure by means of an additive manufacturing process, and the base structure is subjected to a deformation during the additive manufacturing process. The base structure is provided with a starting shape which is selected such that the deformation leads to a desired target shape of the base structure. The invention likewise relates to a corresponding component.
