摘要： A selective laser sintering (SLS) device. The SLS device includes a laser forming unit, a support platform and a driving mechanism. The support platform is configured to support a plurality of raw materials for additive manufacturing of an object including a plurality of sections. The laser forming unit is disposed on the support platform and is configured to lay powders on a surface of each section of the object and sinter the powders. The driving mechanism is disposed under the laser forming unit and includes a vertical driving mechanism and a horizontal driving mechanism. The vertical driving mechanism is connected to the laser forming unit and configured to lift the laser forming unit layer by layer. The horizontal driving mechanism is configured to drive the laser forming unit to move in a horizontal direction with respect to the support platform.

摘要： Methods, systems, and apparatus, for performing additive manufacturing with concrete. One example is an additive manufacturing print head. The print head includes a body defining an internal flow path, a print nozzle at an outlet of the internal flow path, an auger disposed within the internal flow path, a first microwave emitter, and a second microwave emitter. The auger is operable to convey a concrete mixture towards the print nozzle. The first microwave emitter is operable to alter a viscosity of the concrete moisture within the flow path by directing first microwave energy towards the internal flow path. The second microwave emitter is arranged to direct second microwave energy towards the concrete mixture when it exits the print nozzle.

摘要： A 3D printable clay-based mortar cementitious ink includes a blend of commercially available Portland cement, calcium carbonate, sand, and calcined clay. The calcined clay is produced from the calcination of clay having a high kaolinite content of greater than about 60%. The clay is calcined at a temperature of between about 600° C. and about 800° C., preferably between about 650° C. and about 850° C., for a period of one to two hours. In a preferred embodiment, a ratio of calcined clay to Portland cement is about 0.148, a ratio of calcium carbonate to Portland cement is about 0.333, and a ratio of sand to Portland cement is approximately about 3.0. The ratio of water to powder (clay, cement, calcium carbonate, and sand) may range between 0.39 and 0.40.

摘要： In an example, a method includes measuring a temperature of a plurality of regions of a layer of build material in an additive manufacturing apparatus to provide initial temperature values. For each of a plurality of regions which comprise build material which is intended to fuse, an average temperature value of a plurality of neighbouring regions may be determined and the initial temperature values may be replaced with the average temperature value. Based on the replacement temperature values, a representative temperature of an area of the layer of build material may be determined and a heat source may be controlled based on the representative temperature.
