A three-dimensional, additive manufacturing system is disclosed. The first and second printer modules form sequences of first patterned single-layer objects and second patterned single-layer objects on the first and second carrier substrates, respectively. The patterned single-layer objects are assembled into a three-dimensional object on the assembly plate of the assembly station. A controller controls the sequences and patterns of the patterned single-layer objects formed at the printer modules, and a sequence of assembly of the first patterned single-layer objects and the second patterned single-layer objects into the three-dimensional object on the assembly plate. The first transfer module transfers the first patterned single-layer objects from the first carrier substrate to the assembly apparatus in a first transfer zone and the second transfer module transfers the second patterned single-layer objects from the second carrier substrate to the assembly apparatus in a second transfer zone. The first and second printer modules are configured to deposit first and second materials under first and second deposition conditions, respectively. The first and second materials are different and/or the first and second deposition conditions are different.

The invention provides a method for producing a component (100) having a cooling channel system, the method comprising: building a first portion (10) of the component (100) by means of the additive, integrally bonded application of a build material; and—introducing a first cavity (11) having an opening into the first portion (10) of the component (100). The method is characterized in that it also comprises: covering the opening of the first cavity (11) in the first portion (10) by means of a covering part (13);—building a second portion (20) of the component (100) by means of the additive, integrally bonded application of the build material, the build material being applied to the first portion (10) and to the covering part (13); introducing a second cavity (21) having an opening into the second portion (20) of the component (100); and—introducing a connecting channel (90), (90a) into the component (100) by means of material-removing machining in order to form the cooling channel system, the connecting channel (90), (90a) connecting the second cavity (21) of the second portion (20) to the first cavity (11) of the first portion (10) of the component (100).

Devices, systems, and methods are directed to the use of vapor phase change in binder jetting processes for forming three-dimensional objects. In general, a vapor of a first fluid may be directed to a layer of a powder spread across a build volume. The vapor may condense to reduce mobility of the particles of the powder of the layer. For example, the condensing vapor may reduce the likelihood of particle ejection from the layer and, thus, may reduce the likelihood of clogging or otherwise degrading a printhead used to jet a second fluid (e.g., a binder) to the layer. Further, or instead, the condensing vapor may increase the density of the powder in the layer which, when repeated over a plurality of layers forming a three-dimensional object, may reduce the likelihood of slumping of the part during sintering.

Disclosed is an additive manufacturing process for making shingles and roof tiles. The entire shingle, including the substrate, can be manufactured on location, or a substrate can be manufactured at a manufacturing plant and then colored and textured on location to provide a wide variety of shapes and colors of shingles and roof tiles. Costs for inventory and shipping are reduced and a greater variety of shapes and colors can be provided for the shingles and roof tiles. The additive manufacturing equipment can be mounted on a truck so that the additive manufacturing techniques can be a mobile application of the additive manufacturing technology.
