A device includes a material dispenser and a fluid dispenser. The material dispenser is to dispense a build material layer-by-layer, to at least partially additively form a first 3D object. The fluid dispenser is to dispense at least one fluid agent at selectable exterior voxel locations of the respective layers to at least partially define an external surface of the first 3D object as a first color to represent a first non-color material property of at least a first portion of the first 3D object. The selection of the first color is independent of characteristics of the first non-color material property.

A magnet manufacturing device includes a heater, a nozzle, a magnetic field application magnet and a stage. The heater heats a mixture of magnetic particles and a resin material. The nozzle has an internal flow passage that conducts the mixture while the resin material is molten. The nozzle has a discharge port which discharges the mixture and thereby forms each of a plurality of filaments. The magnetic field application magnet applies a magnetic field to the internal flow passage. The stage has a stage surface on which the plurality of filaments are placed. The discharge port is relatively movable with respect to the stage surface such that the plurality of filaments are stacked to form an arbitrary shape.

An ink composition for use as a support ink in three dimensional (3D) printing processes comprises a dispersion of solid particles in liquid carder, compatible with an inkjet print head, wherein after removing the liquid carder, the solid particles serve as support material for a Three Dimensional (3D) printed object, wherein the support material is separable from the 3D printed object.

A compactor is disclosed for use with an additive manufacturing print head. The compactor may include a housing connectable to the additive manufacturing print head. The compactor may also include a compacting wheel, and at least one spring disposed in the housing and configured to exert an axial force on the compacting wheel. The compactor may further include a piston moveable to adjust a distance between the housing and the compacting wheel.

A method of manufacturing a three-dimensional formed object includes cutting a material block so as to fabricate a bottom portion that includes an upwardly projecting underlying layer portion. The method also includes forming a molten material into a single layer or a plurality of layers on a top of the underlying layer portion so as to fabricate a first layer portion in contact with the underlying layer portion.

Disclosed is a method of manufacturing at least one component by 3D printing on a construction platform provided with a heating device, the method comprising: applying a layer of loose particulate material to the construction platform, heating the applied layer of loose particulate material by means of the heating device of the construction platform, outputting a liquid treatment agent onto a partial area of the heated layer of loose particulate material, and repeating said steps to build up the at least one component in layers. The heating by means of the heating device of the construction platform is carried out in such a manner that a temperature of the construction platform increases toward a predetermined construction platform maximum temperature during the build-up of the component to set a surface temperature of the respectively last applied layer.

A layering device for preparation of layers being formed in additive manufacture, each layer formed by printing a mold wall to define a mold space and filling the mold space with a paste to form the layer. The layering device comprises a roller to press the mold wall from above to form a mold layer surface in a plane, a paste applicator and a blade to spread the paste to fill the mold space. The blade is aligned into the plane to smooth the paste flush with the mold layer surface.

A structure comprises: a plurality of substructures and a vernier-based position marker. The plurality of substructures include a first substructure, a second substructure, and at least one electronic component. The second substructure is at least partially additively manufactured on the first substructure. The vernier-based position marker is configured to indicate a relative offset between the first substructure and the second substructure.
