摘要： Support structures are used in certain additive fabrication processes to permit fabrication of a greater range of object geometries. For additive fabrication processes with materials that are subsequently sintered into a final part, an interface layer is formed between the object and support in order to inhibit bonding between adjacent surfaces of the support structure and the object during sintering.

摘要： This invention teaches a multi-sensor quality inference system for additive manufacturing. This invention still further teaches a quality system that is capable of discerning and addressing three quality issues: i) process anomalies, or extreme unpredictable events uncorrelated to process inputs; ii) process variations, or difference between desired process parameters and actual operating conditions; and iii) material structure and properties, or the quality of the resultant material created by the Additive Manufacturing process. This invention further teaches experimental observations of the Additive Manufacturing process made only in a Lagrangian frame of reference. This invention even further teaches the use of the gathered sensor data to evaluate and control additive manufacturing operations in real time.

摘要： Described herein are methods and systems for printing a three-dimensional object. In an example, a method for printing a three-dimensional object can comprise: (i) a metallic build material being applied; (ii) a binder fluid being applied on at least a portion of the metallic build material; (iii) the selectively applied binder fluid can be flash fused to bind the metallic build material and the selectively applied binder fluid by application of an energy flux having an energy density of from about 0.5 J/cm2 to about 20 J/cm2 for less than about 1 second. In the example, (i), (ii), and (iii) can be repeated at least one time to form the three-dimensional object. The binder fluid can comprise a liquid vehicle and polymer particles dispersed in the liquid vehicle.

摘要： This invention teaches a quality assurance system for additive manufacturing. This invention teaches a multi-sensor, real-time quality system including sensors, affiliated hardware, and data processing algorithms that are Lagrangian-Eulerian with respect to the reference frames of its associated input measurements. The quality system for Additive Manufacturing is capable of measuring true in-process state variables associated with an additive manufacturing process, i.e., those in-process variables that define a feasible process space within which the process is deemed nominal. The in-process state variables can also be correlated to the part structure or microstructure and can then be useful in identifying particular locations within the part likely to include defects.

摘要： The present disclosure relates to an additive manufacturing system for forming a part using a powder material. In one embodiment the system makes use of a primary heat generating subsystem to generate a fusing beam for heating and fusing at least one of select portions of a powder layer, or an entire area of a powder layer, deposited on a build plate. The system also incorporates a beam steering subsystem for steering the fusing beam over the powder layer. A supplemental heating subsystem is used to generate a wide area beam to heat a portion of the powder layer either prior to fusing, along with the fusing operation, or subsequent to fusing of the powder with the fusing beam. The wide area beam has an intensity which is insufficient to fuse the powder, and alters a microstructure of the powder layer as the powder layer is at least one of fused or as it cools, to thus relieve stress in the part.

摘要： This disclosure describes an additive manufacturing method that includes monitoring a temperature of a portion of a build plane during an additive manufacturing operation using a temperature sensor as a heat source passes through the portion of the build plane; detecting a peak temperature associated with one or more passes of the heat source through the portion of the build plane; determining a threshold temperature by reducing the peak temperature by a predetermined amount; identifying a time interval during which the monitored temperature exceeds the threshold temperature; identifying, using the time interval, a change in manufacturing conditions likely to result in a manufacturing defect; and changing a process parameter of the heat source in response to the change in manufacturing conditions.

摘要： A molten metal print deposition device includes a reservoir in fluid communication with a deposition head for controlled deposition of a molten metal print medium defined by molten feedstock, and a capillary structure adapted to maintain the molten feedstock from the melt reservoir in a fluidic state for directing and depositing the feedstock onto a substrate. A print medium is defined by an alloy heated to a fluid state in a temperature range defined by but above a liquidus and solidus. A thermal source and control circuit maintain the molten feedstock at a temperature above the liquidus of the print medium during deposition.

摘要： A metals-based additive manufacturing machine and method are disclosed. The machine and method include a hybrid temperature monitoring system. The hybrid temperature monitoring system includes a Raman spectrometer, a single-element ultrasound transducer, and a phased-array ultrasound pair. The hybrid temperature monitoring system can generate a real-time three-dimensional temperature map of the melt pool and optionally a portion of the metal powder base and/or a formed portion of a desired artifact. The real-time three-dimensional temperature map can be used for optimizing the metals-based additive manufacturing process in real-time or during subsequent process runs.

摘要： Various embodiments include a method for additive manufacturing of a building structure on using a simulation comprising: accessing a data set for the building structure describing the building structure in layers; calculating a global heat development in previous layers based a building history and heat input by an energy beam; determining a local heat development in a vicinity of the heat input; determining the process control based on the global and the local heat development; loading correction measures from a database; and assigning the correction measures locally to individual vectors of a tool path of the energy beam. At least one mass integral is calculated for individual vectors of the tool path. The measures are determined on the basis of a comparison of the calculated mass integral with mass integrals stored in the database.
