Metal binder jet 3D printing technology has become a strong trend in the world, and the quality, efficiency, and cost have been greatly optimized. It has shown strong vitality in the mass production of metal parts.
In 2019, one of the world's leading metal binder jet 3D printing manufacturers, the 3D printer of Digital Metal of Sweden has been sold in the United States. It was initially exhibited at one time, and was finally bought by customers after multiple technical evaluations and benchmark tests by customers; in September 2019, Taiwanese customers have achieved the first batch of 3D printed parts; in October 2019, Japan The first 3D printer also started operations at the customer site.
Now, Digital Metal metal binder jet 3D printer has also entered the Chinese market.
Process principle of metal binder spraying technology
In general, the process flow can be summarized as: 3D printing→cleaning→sintering→surface treatment.
The printing process starts with a CAD composition file formed according to the target part, and high-precision printing is performed using metal powder and adhesive in the printer. After completion, sintering is carried out to obtain high-strength, high-resolution metal parts. Finally, surface treatment is performed to improve the apparent quality. Currently, Digital Metal® can provide printing on stainless steel or titanium alloy. Other materials are also being rapidly developed.
DM P2500 is the first metal binder spray system to pass UL certification (file number E496006), and it also has CE certification that is consistent with EC Machinery Directive 2006/42/EC.
With joint efforts with customers, it won the 2019 3D Printing Industry Award. The 3D Printing Industry Award is a global event in the 3D printing industry organized by the world-renowned media company 3DPI (3D Printing Industry).
Technical advantages
1. Low cost in large quantities
Each individual part in a batch of parts can be customized, regardless of the quantity. It can print different parts on the same production line at the same time, which increases the flexibility of customized products in the market and improves market value.
2. No support
The process of high-precision printing does not require any supporting structure, nor does it involve any heat transfer, which means that it can be packed more densely to the print box. The spacing between the parts to be printed is less than 1 mm. Parts can be placed on top of each other in several layers.
3. Excellent surface quality
With digital metal technology, the average surface quality can reach 6um range without any post-processing, and other additive manufacturing processes usually leave a rougher surface. Surface quality is very important for parts with channels inside, because post-processing of the surface of these parts is very challenging. Of course, other operations can also be added to the outer surface to achieve an appearance that is more in line with the specific needs of customers.
Application field
Industrial application
3D metal printing technology makes it possible to produce complex industrial metal parts quickly and efficiently. They can be hollow or mesh, with notches, ducts, cavities and internal structures. Almost any design, no matter how complicated, can be realized using this technology.
Dental/Medical
The 3D metal printing technology in the dental/medical field also improves the possibility of manufacturing brand new tools and components, and optimizing functions, without being restricted by traditional manufacturing.
Aerospace
By creating hollow or meshed interiors of lightweight and strong metal parts, Digital Metal can help advance aircraft design.
Design
3D metal printing gives design a new level of creative freedom!
