Problems solved by technology

If the powder coating is uneven and uneven, defects will occur inside the part during the laser sintering forming process, the forming accuracy will decrease, and even the forming will not be possible.
At present, it is difficult to monitor the uniformity of powder spreading in the forming process of SLS and SLM. It can only be observed manually, which is time-consuming and laborious, and it is also difficult to track and observe in real time.
At the same time, it is difficult to measure the outline size of each sintered layer forming part, and the printing accuracy cannot be guaranteed

Abstract

The invention relates to a laser rapid prototyping powder coating uniformity detection system and detection method, which belongs to the technical field of laser rapid prototyping powder paving detection technology, and provides a laser rapid prototyping powder paving that can monitor whether the powder paving is smooth in real time and effectively improve the molding quality Uniformity detection system and detection method. The technical scheme adopted is that a powder spreading device, a powder supply cylinder, a forming cylinder and a collection cylinder are arranged in the molding cavity, and a laser and an image acquisition device are installed on the top of the molding cavity. There is a supplementary light on the side, and the laser, image acquisition device and supplementary light are all connected to the control system; the invention is widely used in the powder coating uniformity detection of laser rapid prototyping.

Description

technical field [0001] The invention relates to a laser rapid prototyping powder spreading uniformity detection system and a detection method, belonging to the technical field of laser rapid prototyping powder paving detection. Background technique [0002] 3D printing (additive manufacturing) technology is an emerging technology that is rapidly developing in the manufacturing industry, and it is called "manufacturing technology with industrial revolution significance". It is a manufacturing technology based on the principle of discrete and stacking. It discretizes the three-dimensional computer-aided design (CAD) model of the part in a certain way, and becomes a machinable discrete surface, discrete line and discrete point, and then uses physical or chemical means. Stack these discrete faces, segments, and points into a part shape. 3D printing technology can transform the designed 3D CAD model into parts with certain structure and function through superposition forming met...
