Abstract

The invention discloses a 3D printing detection method used for detecting whether a current 3D-printed surface material is consistent with a design sample at real time. A 3D printer contains a 3D printer body and a movable infrared spectrometric analyzer (containing infrared total reflection accessories), and is simultaneously provided with error correction software for correcting or choosing to reprint by comparing infrared spectrum of a test point with standard spectrum of the design sample. According to the invention, accuracy of a material used for a printed object can be monitored at real time, defective rate of printing is reduced, unnecessary material wastage is minimized, and time is saved.

Description

technical field [0001] The invention relates to a 3D printing detection method based on infrared spectrum analysis, which is applied to the 3D field. Background technique [0002] 3D printing technology is an emerging new manufacturing technology, also known as "additive manufacturing" technology academically. It is based on the three-dimensional CAD model data, and adopts the method of directly manufacturing the three-dimensional physical solid model that is completely consistent with the corresponding mathematical model by adding materials to the layer-by-layer manufacturing method. The content of 3D printing technology covers all printing processes, technologies, equipment categories and applications related to "rapid prototyping" at the front end of the product life cycle and "rapid manufacturing" in the full production cycle. [0003] The technologies involved in 3D printing include the integration of CAD modeling, measurement, interface software, numerical control, pr...
