A system for additive metal manufacturing, including a deposition mechanism, a translation mechanism mounting the deposition mechanism to the working volume, and a stage. A method for additive metal manufacturing including: selectively depositing a material carrier within the working volume; removing an additive from the material carrier; and treating the resultant material.

A three-dimensional shaped article producing composition is provided and contains a plurality of particles, a solvent for dispersing the particles, and a binder having a function to temporarily bind the particles to one another in a state where the solvent is removed, wherein a volume-based average particle diameter of the particles is 0.1 μm or more and less than 50 μm, and a content ratio of the binder is 1.5 vol % or more and 10 vol % or less.

In embodiments, a method for additive manufacturing of a metal-incorporated resin object comprises illuminating a curable composition comprising prepolymers, a metal compound, a photoredox catalyst, a polymerization initiator, and optionally, a redox agent, with light having a first wavelength, wherein the metal of the metal compound is characterized by an initial oxidation state, and the illumination induces polymerization reactions between prepolymers to form a first cured region and induces redox reactions to change the initial oxidation state of the metal in the first cured region. The method further comprises inducing polymerization reactions between prepolymers to form a second cured region different from the first cured region without inducing redox reactions in the second cured region. Also provided are the curable compositions, the additive manufacturing systems for carrying out the methods, and the metal-incorporated resin objects.

A method for producing a collagen-containing sheet material, wherein a collagen-containing suspension is dried in such a manner that the collagen settles during drying and forms a transparent skin.

A method to produce a container made of a plastic composition having an inner coating with a higher mechanical stability and/or a better adhesion to the container, includes preparing a plastic composition with at least one base polymer material and at least a first additive comprising globe-like particles having a hardness on the Mohs scale of at least 4,and extrusion blow molding of a container. The globe-like particles, which located on the inner surface of the container, increase the surface area and the hardness of the inner surface of the container. The method also includes applying the at least one metal layer of the inner coating onto the inner surface of the container, wherein the applied metal layer bonds to the globe-like particles of the first additive located on the inner surface of the container.

3D printable ink compositions for forming objects, films and coatings are provided. Also provided are methods of printing the ink compositions and methods for making the ink compositions. The ink compositions include an elastic polymer binder and may have high loadings of solid particles.

An ejector element with a trigger for a belt buckle sensor includes a plate-shaped ejector body and a trigger blade of a magnetic and/or metallic material for producing a change in a magnetic field of a Hall sensor or an inductive sensor. The ejector element is distinguished by the fact that the trigger blade is connected in one piece to the ejector body, wherein the one-piece connection between the trigger blade and the ejector body is produced by an injection-molding process.

A method of detecting faults and ensuring integrity of membranes having magnetically functionalized particles, including moving a magnetometer over the membrane to measure at least one magnetic property, mapping the location of the measured properties, identifying anomalies among measured properties including the location of such anomalies, and repairing the membrane at the location where anomalies are identified.

A 3D printing device for producing a three-dimensional component form at least two different materials. The 3D printing device has both a spray-printing unit and an electron-beam and/or laser unit. To produce the three-dimensional component, the spray-printing unit is designed and set up to spray the at least two different materials, and the electron-beam and/or laser unit is designed and set up to join sprayed-on material integrally by fusing by means of an electron beam and/or by means of a laser beam of the electron-beam and/or laser unit.

A solid freeform fabrication material set includes a first solid freeform fabrication liquid material including a solvent, a resin A soluble in the solvent, and an inorganic particle; and a second solid freeform fabrication liquid material including a resin B soluble in water and a second colorant.
