A processing system includes: a processing apparatus for processing an object; a rotation apparatus for rotating a holding part holding the object; a movement apparatus for moving at least one of the processing apparatus and the holding part; a measurement apparatus for measuring at least a part of the object held by the holding part; and a control apparatus for controlling the movement apparatus and the rotation apparatus based on a measured result by the measurement apparatus to rotate the holding part and to move at least one of the processing apparatus and the holding part

A thermal control apparatus including a body defining a centerline axis extended along a height and a circumferential direction extended relative to the centerline axis. The body forms a flow circuit therethrough, an inlet opening, and an outlet opening each in fluid communication with the flow circuit. The flow circuit is extended in parallel flow arrangement along the circumferential direction from the inlet opening to the outlet opening. A cavity is extended at least partially through the body along the centerline axis. A thermal control system includes the thermal control apparatus, a fluid flow device configured to provide a flow of heat transfer fluid to the apparatus through the inlet opening and to receive the flow of heat transfer fluid from the outlet opening of the apparatus, and a flow conduit providing fluid communication of the flow of heat transfer fluid between the fluid flow device and the apparatus.

A method for determining a set point for measurements from a temperature sensor of an apparatus for the layer-by-layer formation of a three-dimensional object from particulate material, and associated controllers. The method includes distributing a calibration layer of particulate material over a build bed surface; selectively applying absorption-modifying fluid to a reference area or a surrounding area thereof, on the build bed surface; (c) lowering the build bed surface to a calibration depth, (d) applying heat to the reference area using a moveable heat source while measuring the temperature increase of a sub-reference area over a duration of time and/or taking optical readings of an optical property of the sub-reference area over the duration of time; (e) determining the onset of fusion of the particulate material; and (f) applying the onset of fusion as the set point for subsequent temperature measurements.

A machine for additive manufacturing of components by sintering powder includes a framework, a working zone, at least two beam emission and control modules, and at least two actuators. Each module, which is structured to emit an energy beam and to control the energy beam, is mounted inside the framework and is provided with an emission source and an optical system for focusing the energy beam emitted from the source. Each module acts on the working zone to manufacture a same component. Each optical system is axially movable in translation with respect to the framework. The actuators are associated with the optical systems, respectively, and are arranged to adjust axial positions of the optical systems with respect to the working zone, the axial positions being adjustable independently of each other.

A slicer in a material drop ejecting three-dimensional (3D) object printer determines the number of material drops to eject to form a perimeter in an object layer and distributes a quantization error over the layers forming the perimeter. The slicer also identifies the location for the first material drop ejected to form the perimeter using a blue noise generator.

A lamination molding apparatus includes a molding room, a chamber, a chamber window, a molding table, a molding table driving device, surrounding walls, an irradiation device, a measuring unit, and a controller. The measuring unit includes a first measuring device acquiring a measured value of a light intensity, and a second measuring device acquiring a value of a beam diameter, and measures laser beams outputted based on set values of light intensity during molding. The controller determines an abnormality has occurred when a slope of a linear function obtained from a relationship between the measured value of the light intensity and the value of the beam diameter at a predetermined height is out of a predetermined range, or when a slope of a linear function obtained from a relationship between the measured value of the light intensity and a value of a focal position is out of a predetermined range.
