There is no large workshop, no mechanical "group dance". At 10 am on the 4th, the reporter walked into the Guangzhou 3D Printing Industrial Park located in Dongsha, Liwan, Guangzhou, where production was relatively quiet. Feng Yongjie, a 3D printing engineer at Riton, is operating a metal laser 3D printer. After pressing the operation button, the cobalt chromium powder in the powder cylinder of the printer is melted and welded under the action of the laser, forming 600 layers layer by layer. After waiting for 3 hours, a row of steaming metal crowns is released from the furnace.
Finished products printed using 3D printing technology
Additive manufacturing (3D printing) technology is widely used in vehicle development, construction, biomedical, aerospace, power machinery, personalized design, and other fields. Riton, where Feng Yongjie works, focuses on printing customized products such as dental crowns, dental bridges, and brackets in the field of oral medicine. A single dental crown belongs to a single piece, and it can produce 180 crowns in 3 hours, "Feng Yongjie said. 3D printing can find a balance between customized production and mass production, and small-scale production of customized products.
Make a model using a computer before 3D printing
Wearing dust covers, anti-static gloves, and dust suits, Feng Yongjie, 22, has been working as a senior 3D printing engineer for two years. His printed products have high accuracy and a matching rate of nearly 100% with the requirements. He can judge whether the printing process is smooth at a glance at the machine. Printing product design drawings into visible, tangible, and well used finished products is crucial for accuracy. Feng Yongjie said that there is a great deal of emphasis on how to set the laser power, support structure, and how to place the finished product. It requires rich experience, otherwise the product is prone to deformation, becoming waste, or the accuracy is not enough to meet the needs of the customizer.
Feng Yongjie is operating a 3D printer
Looking forward to the development prospects of 3D printing, many young people like Feng Yongjie are willing to take root in the high-end manufacturing industry. Whatever you want to do, you can do it, and printing out your own design is very fulfilling, "he said.
