Abstract

The invention relates to a device and a method used for 3D (Three-Dimensional) printing. A 3D object detection device disclosed by the invention comprises one or a plurality of processing circuits, wherein the processing circuits are configured to execute the following steps that: obtaining the shape robust value of a 3D object; matching the shape robust value of the 3D object with the shape robust value of a 3D sample in a 3D sample database; under a situation that the shape robust value of the 3D object is matched with the shape robust value of the 3D sample, according to the matched design robust value of the 3D sample, determining the design robust value of the 3D object; and on the basis of the matching result of the shape robust values and a determining result, detecting the 3D object. When the device and the method used for the 3D printing are used, the owner, the designer and the manufacturer of a 3D model can protect the 3D model from the invasion of intellectual property.

Description

technical field [0001] The present disclosure relates to the technical field of 3D printing, and specifically relates to a 3D object detection device, a 3D object detection method, a device for establishing a 3D specimen database, a method for establishing a 3D specimen database, a 3D printer, and a 3D object recognition system. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] 3D printing technology, also known as AM (Additive Manufacturing, additive manufacturing) technology, rapid prototyping (Rapid Prototyping) manufacturing technology or stereolithography (Stereolithography) technology, is a computer-assisted method of making 3D entities based on 3D model files. technology. 3D printing technology can use different printing materials, such as plastics, resins, ceramics and metals. Low-cost 3D printers commonly use materials such as PLA (polylactic acid, polylactic ac...
