摘要： The method is for the discriminant monitoring of a composite multi-material assembly (1) having at least one internal layer (10) made of a first, electrically conductive composite material and a second layer (11) made of a second, electrically insulating composite material, the second layer (11) covering the first internal layer (10). The method includes: —preparing the composite multi-material assembly (1) by exposing a portion (101) of the internal layer (10), which constitutes a first electrode; —applying a second electrode (103) to the surface of the second layer (11), one of these electrodes (103) being earthed; —performing discriminant monitoring wherein a current is generated between the first electrode (101) and the second electrode (103) by applying a threshold voltage Us predetermined by calibration to characterize a lack of structural defects, the appearance of a breakdown at a voltage lower than the threshold voltage Us being indicative of the presence of at least one structural defect in the composite assembly (1).

摘要： The invention is a system and method for printing 3D objects that employs a hydraulic device. The device may include a piston, a platform, multiple chambers, and a channel, wherein the channel and chambers are fluidly connected and configured to hold a desired amount of 3D printing material suitable for 3D-printing objects for a wide range of applications. In an exemplary method, moving the piston transfers 3D printing material from one chamber to another chamber in which a build platform is situated; radiation from a light engine coupled to the chamber that includes the platform exposes the 3D printing material to a curing light on a surface of the platform. In exemplary embodiments, the chambers may be designed just small enough so as to facilitate the printing of a single small 3D-printed object.

摘要： Systems and methods for designing additively manufactured objects are provided. In some embodiments, a method includes receiving a treatment plan for a patient's teeth, and determining a set of appliance parameters for a dental appliance configured to implement the treatment plan. The method can also include determining a set of manufacturing parameters for a fabrication system to be used to additively manufacture the dental appliance. The method can further include generating a 3D digital representation of an appliance geometry for the dental appliance. The appliance geometry can be configured to mitigate loss of fidelity at a target region of the dental appliance due to at least one manufacturing parameter of the fabrication system.

摘要： In a method for treating combustible and/or reactive particles (34) which have been separated from a gas stream (32) by means of a separation device (36) an oxidizing agent is supplied to an atmosphere surrounding the particles (34) so as to cause a passivating oxidation of at least a part of the particles (34). A content of the oxidizing agent in the atmosphere surrounding the particles (34) is detected and the supply of the oxidizing agent to the atmosphere surrounding the particles (34) is controlled in dependence on the detected content of the oxidizing agent in the atmosphere surrounding the particles (34).

摘要： Some implementations of the disclosure are directed to an additive manufacturing build plate structure for metal build surface stabilization during 3D printing and facile release of 3D printed objects. The build plate includes a body having a recessed section formed through a first surface of the body, the recessed section including a bottom surface within the body and sidewalls extending to the bottom surface. The recessed section is configured to be filled with a solid form of a metal or metal alloy that provides a printing surface for forming a 3D object in a 3D printing device. The recessed section includes a locking mechanism configured to prevent lift-up of the solid form of the metal or metal alloy during 3D printing in the 3D printing device.

摘要： Systems (100) and methods (1000) for additively manufacturing or repairing a component from a base material (10). The system may include a laser metal deposition (LMD) system (200) operably connected to a means for cooling (300) the base material during laser processing of additive materials deposited in a melt pool on the base material. The LMD system includes a laser energy source (202) configured to direct laser energy towards the base material to form the melt pool thereon and to processes the deposited additive materials to form layers on the base material upon solidification. The means for cooling may be configured to cool the base material to within a cooling temperature range during the LMD process, which results in, e.g., a cooling/freezing effect. This cooling effect shortens the solidification period during laser processing and allows for weld heat to be released from the base material.
