Recently, Cummins is the first to use the new high-precision Binder Jet (bond jet 3D metal printing) technology to produce parts finalized, marking Cummins’3D printingTechnology application is another milestone towards Industry 4.0. This part is the nozzle adapter of Cummins Emission Treatment System (CES) for high-horsepower engines and is awaiting the formal approval of Cummins Parts Production Approval Program (PPAP). The spray gun head adapter is an important part of the Cummins engine exhaust system. It atomizes the exhaust gas of the diesel engine and injects it into the engine exhaust flow to reduce the engine’s nitrogen oxide (NOx) emissions.
Additive manufacturing technology produces parts with unique advantages, including lightweight design, improved fluid and airflow geometry, and avoiding the added complexity of cross-drilling. After obtaining the final approval, the part is expected to be officially produced by the end of this year.
Start economically
As early as April 2019, Cummins began to increase investment in the field of Binder Jet technology. Binder Jet technology uses the print head to spray the adhesive into the metal powder, through the liquid adhesive, the metal powder is selectively bonded into the shape of the part, and they are superimposed to form a solid metal part. Depending on the complexity of the parts, this technology is 60 to 100 times faster than other laser printing processes, making mass production possible.
In addition, Binder Jet technology also has environmental advantages. Unlike traditional mechanical processing, Binder Jet printers can extract 100% of the residual powder of printed parts, and recycle them through the system to achieve repeated use in the production of other parts.
In 2020, Cummins established an additive manufacturing technology laboratory in the Manufacturing Engineering Development Center (MEDC) in Columbus, Indiana, dedicated to the development and verification of the industrial production of Binder Jet technology. The Cummins engineering team has accumulated in the design and production of additive manufacturing. Has gained a wealth of experience and skills.
At present, the Cummins additive manufacturing production and engineering team is still designing and printing some other concept parts, and it is expected that more parts can be produced this year. Cummins currently has two second-generation Binder Jet printers, one in the Additive Manufacturing Technology Laboratory in Columbus, Indiana, and the other in the GE Additive Disruptive Innovation Laboratory near Cincinnati, Ohio. Cummins and GE Additive are actively cooperating to develop the third-generation Binder Jet technology to support higher-volume, higher-quality, and lower-cost industrial solutions. The strategic cooperation between the two parties is committed to achieving low-cost, high-quality and production applications that meet the required scale. Cummins has been deeply involved in the field of additive manufacturing. The use of Binder Jet technology to print parts is another latest development of Cummins in this field.
Starting from production
For many years, the Cummins engineering and manufacturing team has been using polymers (plastics and resins) to print parts, and has continuously made breakthroughs in the field of small-batch metal printing. Cummins owns three GE Additive Concept Laser M2 machines, one of which is in the Cummins Technology Center in Columbus, Indiana, and the other two are in the Cummins R&D Center in San Luis Potosi (SLP), Mexico. In addition, Cummins also uses the 3D sand printing technology of the SLP center to manufacture part molds.
Benefiting from the advantages of cost and production cycle, additive manufacturing technology is very suitable for the parts needs of after-sales customers and small-volume customers.Sales of the first metal since 20193D printingSince the parts, Cummins has approved more than 203D printingParts, the number of parts shipped reached 350.
In the future, Cummins will continue to cooperate with GE Additive to further enhance the production capacity of additive manufacturing technology, accelerate the speed of products to market, and increase production.
BJ technology enters the production field
Dr. Maximilian Munsch, partner of AMPOWER, powder bed systems are still in the metal and plastic industries3D printingThe mainstream technology of technology. By 2025, AMPOWER expects that the market share of powder bed systems will decrease. For example, the bonding agent jetting in metal (BJT) and the plastic printing (DLP) technology will rise. CONTEXT is expected after 20223D printingThe market will rebound across the board.continue to use3D printingMass production is still the key to accelerating growth, and technologies such as powder bed melting and barrel photopolymerization (for plastics) and binder injection (for metals) are ready to help this push. BJ technology has seen rising demand in China since 2020. The domestic enthusiasm for this technology has increased significantly, and the purchase intention has increased significantly.
