3D printing device and forming method thereof

Abstract

The invention discloses a 3D printing device and a forming method of the device. The 3D printing device comprises a machine base, a laser radiation device, a material storage device, an air cylinder, an image sensor and a controller. As a sliding device arranged on the machine base drives the laser radiation device to slide, and a plurality of laser diodes are arranged inside the laser radiation device in an array manner, scanning forming from lines to faces can be carried out on workpieces in a large area, the forming speed is high, and the forming efficiency is high; a displacement sensor is arranged in a working platform, position information can be obtained in real time, the lifting height of the working platform can be precisely obtained, and the forming quality of the workpieces can be improved; and the image sensor is arranged so that a formed layer section image can be obtained and sent to a controller, the layer section image can be compared with data of stored layer section, printing correctness of each layer section can be ensured, and the forming quality of the workpieces can be further improved. The device is simple in structure, convenient to operate, good in forming quality, high in forming speed and suitable for large-scale industrial production.

Description

Technical field: [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing device and a forming method thereof. Background technique: [0002] 3D printing, a kind of rapid prototyping technology, is a high-tech manufacturing technology based on material accumulation method, which is considered to be a major achievement in the manufacturing field in the past 20 years.
