A method of additively manufacturing a three-dimensional object may be performed using an irradiation sequence that is based at least in part on a predicted location of one or more fume plumes emitted from the powder material when irradiated by a plurality of energy beams. An exemplary method may include determining, with a computing device, an irradiation sequence for selectively consolidating powder material using an energy beam system of an additive manufacturing machine, and providing control commands, from the computing device to the energy beam system, configured to cause the energy beam system to emit a plurality of energy beams to selectively consolidate the powder material.

Disclosed is a distribution device and a manufacturing method for a full-body textured porcelain stoneware slab and relates to the field of construction ceramic tile production. The distribution device includes a feeding assembly, a powder-preforming box, and a belt conveying assembly, where the powder-preforming box is arranged at an included angle α with a conveying plane of the belt conveying assembly, and 61°≤α≤90°, and an intersecting line of a lower end of the powder-preforming box and the conveying plane of the belt conveying assembly is at an included angle β with a center line of the conveying plane of the belt conveying assembly, and 45° ≤β≤90°. A process using the distribution device can produce a full-body textured porcelain stoneware slab of a natural flowing effect, and can form a straight or diagonal textured pattern effect as needed.

Provided are systems and methods for forming a casing liner in a wellbore of a hydrocarbon well.

The present disclosure provides three-dimensional (3D) printing processes, apparatuses, software, and systems for the production of at least one desired 3D object. The 3D printer system (e.g., comprising a processing chamber, build module, or an unpacking station) described herein may retain a desired (e.g., inert) atmosphere around the material bed and/or 3D object at multiple 3D printing stages. The 3D printer described herein comprises one or more build modules that may have a controller separate from the controller of the processing chamber. The 3D printer described herein comprises a platform that may be automatically constructed. The invention(s) described herein may allow the 3D printing process to occur for a long time without operator intervention and/or down time.

In an example of a three-dimensional (3D) printing method, a ceramic build material is applied. A detailing agent fluid is applied to a portion of the ceramic build material. The detailing agent fluid includes a cationic polymer. A liquid functional material, including an anionically stabilized susceptor material, is applied to another portion of the ceramic build material that is in contact with the portion of the ceramic build material having the detailing agent fluid thereon, such that at least some of the anionically stabilized susceptor material reacts with at least some of the cationic polymer that is in contact therewith to prevent spreading of the anionically stabilized susceptor material.

A system for forming a product with different size particles is disclosed. The system comprises at least one print head region configured to retain a first group of print heads configurable to additively print at least a first portion of the product with a first material and a second group of print heads configurable to additively print at least a second portion of the product with a second material. The described system may also comprise a processor configured to regulate the first group of print heads and the second group of print heads to distribute the first material and the second material. A method of making an object by ink jet printing using the disclosed system is also disclosed.

The invention relates to a method for controlling the movement of an end hose arranged on a concrete placement boom of a concrete pump with a display device arranged in the region of the end hose by means of a control device, comprising the following steps: outputting a signal for displaying a predefined movement direction to the display device; receiving a predefined speed for moving the end hose from an actuation device; and calculating and outputting control signals for controlling the concrete placement boom in such a way that the end hose is moved in the predefined movement direction at the predefined speed. The invention also relates to a corresponding control device, a system, a concrete placement boom and a computer program for controlling the movement of an end hose arranged on a concrete placement boom of a concrete pump.

A 3D printing system comprising: a selective solidification module to: form a printed article by processing a build material; and form a printed container encompassing the printed article and a portion of unused build material about the printed article, the printed container defining a first port and a second port fluidly connected to the first port. The 3D printing system further comprises a connector to couple to the first port or second port of the printed container; and a pump fluidly connected to the connector to cause a fluid to flow through the printed container from the first port to the second port such that the printed article is cooled by the fluid flow.

The invention relates to an arrangement for the layer-by-layer formation of mouldings from a particulate material, comprising at least one process unit which can be guided to and installed in the arrangement, preferably automatically, and which comprises a printing unit and a coating system with a dynamic filling system; or/and a receiving device for a building container; a preferably automatic feeder for the building container; and an adjustment device for offline preparation of the process unit.

An additive manufacturing apparatus includes a platform, a dispenser configured to deliver a plurality of successive layers of feed material onto the platform, at least one light source configured to generate a first light beam and a second light beam, a polygon mirror scanner, an actuator, and a galvo mirror scanner. The polygon mirror scanner is configured to receive the first light beam and reflect the first light beam towards the platform. Rotation of the first polygon mirror causes the light beam to move in a first direction along a path on a layer of feed material on the platform. The actuator is configured to cause the path to move along a second direction at a non-zero angle relative to the first direction. The galvo mirror scanner system is configured to receive the second light beam and reflect the second light beam toward the platform.
