In the step for laminating the clad layer, the following requirements are satisfied: 20≤A≤35, 1.1≤B≤1.3, and (40% by mass)≤R2≤(65% by mass). In the formulae, A represents a laser heat input index, B represents a powder feeding rate index, and R2 represents a content ratio of the second powder in the powder material.

摘要： The present disclosure relates to an eccentric extreme high-speed-rate laser hybrid manufacturing method for a rotary engineering component. By positioning an extreme high-speed-rate laser direct energy deposition machining head at a predetermined eccentric distance, the damage caused by reflected light to the machining head is effectively reduced, to prolong a service life of the machining head. Also a conventional form of a molten pool in extreme high-speed-rate laser direct energy deposition can be changed, namely from a “falling” form caused by a high-speed movement and a gravity to a “climbing” form. Thus, in extreme high-speed-rate laser direct energy deposition machining, the molten pool has a longer time to fully contact a surface of the rotary engineering component to form desirable bonding performance.

摘要： Disclosed herein are systems and methods of use thereof. For example, disclosed herein are systems and methods for printing using superluminescent light. For example, disclosed herein are methods of printing with superluminescent light, the methods comprising: generating a patterned light sheet from superluminescent light, with the proviso that the superluminescent light is not generated by a femtosecond laser; and projecting the patterned light sheet at an image plane onto or within a sample comprising a photosensitive material; thereby simultaneously illuminating a selected portion of the photosensitive material within a layer of the sample corresponding to a selected pattern, thereby causing a simultaneous photoreaction that prints structures in the selected pattern.

摘要： A method of additively manufacturing a three-dimensional object may include allocating irradiation of respective ones of a plurality of sequential layers of construction material between a first region and a second region based at least in part on a first irradiation time and/or a second irradiation time. Irradiation of the first region is allocated to a first scanner and the first irradiation time is indicative of a time required for the first scanner to irradiate the first region with respect to at least one of the plurality of sequential layers of construction material. Irradiation of the second region is allocated to a second scanner and the second irradiation time is indicative of a time required for the second scanner to irradiate the second region with respect to at least one of the plurality of sequential layers of construction material. The first irradiation time and the second irradiation time may be at least approximately the same.

摘要： The present invention relates to a Si-containing high-strength and low-modulus medical titanium alloy, and an additive manufacturing method and use thereof. The additive manufacturing method comprises alloy ingredient design, powder preparation, model construction and substrate preheating, and additive manufacturing molding; wherein the Si-containing high-strength and low-modulus medical titanium alloy is designed in the ingredient proportion of Ti 60-70 at. %, Nb 16-24 at. %, Zr 4-14 at. %, Ta 1-8 at. %, Si 0.1-5 at. %. The principle of the present invention is design of a medical β-type titanium alloy having high-strength and low-modulus and good biocompatibility by using d-electron theory; reducing the difference of thermal expansion between the silicide and the β-Ti phase by preheating, and at the same time, ensuring that there is a sufficient degree of cooling in the additive manufacturing process to promote the transition of the alloy from the divorced eutectic reaction to the precipitation reaction, thereby solving the common problems, such as the deterioration of mechanical properties caused by the continuous distribution of the Si-containing phase along the grain boundary and the cracking caused by the difference of thermal expansion coefficient between different phases.
