CPC Class B33Y

Provided is a reflector comprising: an outer wall; and an inner wall which reflects the xenon lamp light from a xenon lamp toward an object to be light sintered, and which consists of inner side walls and an inner top wall which are spaced apart by a predetermined distance from the outer wall to allow cooling water for cooling heat generated by the xenon lamp light to flow, wherein at least a part of the inner side walls has the same thickness as at least a part of the inner top wall.

The disclosed technology provides for printing a 3D structure in-situ within a patient during a surgical procedure. The disclosed technology can include generating instructions for a 3D printer of a surgical robot to print a structure within the patient's body, simulating and verifying the instructions, and autonomously or semi-autonomously executing the instructions, once verified, during a surgical procedure. Generating the instructions for printing the 3D structure within the patient can be based on image data of the patient. Generating the instructions can also include selecting substrate materials that are both safe for the patient and having desired properties of the final printed structure. Modifications can be made to the instructions based on results from the simulation. The disclosed technology provides for application of safe substrate material directly to hard and/or soft tissues within the patient's body via an additive manufacturing process, such as 3D printing.

Disclosed are example embodiments of methods and systems for improving teeth appearance and repositioning of the teeth. One of the systems is an appliance that includes: an outer shell with simulated teeth that approximate a final teeth arrangement; and inner cavities configured to receive a patient's teeth and to incrementally reposition the teeth toward the final teeth arrangement.

An additive manufacturing process comprising:

A shaping device includes a cutting unit configured to cut a first shaped product or an intermediate component formed by adding a shaping material to the first shaped product on a stage, and a control unit configured to control the cutting unit to cut the first shaped product or the intermediate component to shape a shaped object different from the first shaped product and the intermediate component.
