MAHLE produces high-performance aluminum pistons using 3D printing for the first time

As part of a cooperation with sports car manufacturer Porsche and mechanical engineering company Trumpf, MAHLE has produced high-performance aluminum pistons using 3D printing techniques for the first time. The pistons were successfully tested on the engine test bench for Porsche’s 911 GT2 RS sports car. Whereas standard forged pistons have reached the limits of their performance potential, it is conceivable that the power of the 700 HP Porsche engine could be boosted by 30 HP with an associated increase in efficiency. MAHLE is specifically developing its expertise in 3D printing, so that, in the future, it will also be able to support its customers in the field of alternative drives, including electric drives, by supplying suitable components for drives, thermal management, and mechatronics promptly.

Additive manufacturing: joint project with Porsche and Trumpf yields world’s first 3D printed piston Successful testing in Porsche 911 GT2 RS: 200-hour endurance test on the test bench under the toughest conditions3D printed piston increases the performance and efficiency of the 700 HP drive unitMAHLE is also specifically developing its expertise in 3D printing for application in the field of alternative drives“The results of the project confirm the great potential of 3D printing and demonstrate MAHLE’s particular competence in the field of high-performance small and limited runs and in relation to prototyping and aftermarket,” says Dr. Martin Berger, Head of Corporate Research and Advanced Engineering at MAHLE.
Frank Ickinger, project manager at Porsche, comments: “Thanks to the close cooperation of everyone involved, we were able to demonstrate the potential of additive manufacturing in our top-of-the-line high-performance sports car, the Porsche 911 GT2 RS, thus clearing the way for its use in future drives. In terms of technology, this is the start of a new chapter for us, which opens up completely new possibilities in design and production.” Steffen Rübling, project manager at Trumpf, also sees big opportunities for 3D printing in future manufacturing processes. “The project illustrates how 3D printing can be used to further improve components whose performance potential has already been exhausted by decades of development. This will benefit many other industries, such as aerospace and energy.”
Bionic design reduces piston weight and increases maximum engine speedThe new process presents the option of implementing a so-called bionic design. In this approach, which mimics natural structures such as the human skeleton, material is added only in loaded areas, with the structure of the piston being adapted to the load. It saves material and has the potential to make the 3D printed piston up to 20 percent lighter than its conventionally manufactured counterpart while increasing rigidity.
In addition, the developers at MAHLE have introduced an optimally positioned and specially shaped cooling gallery near the piston rings. This design is based on MAHLE’s many years of experience with thermal processes on the piston and is only possible using 3D printing. The cooling gallery reduces the temperature load at the so-called top land, a particularly stressed part of the piston, thus optimizing combustion and paving the way for higher maximum engine speeds.
The new production process is based on a special aluminum alloy developed by MAHLE with a long history of successful use in cast pistons. The alloy is atomized into a fine powder and then printed in a process known as laser metal fusion (LMF). A laser beam melts the powder to the desired layer thickness, followed by the application of a new layer on top, thereby building the piston up one layer at a time. Using this method, 3D printing specialist Trumpf produces piston blanks made up of approximately 1,200 layers in around 12 hours.
“This project involved multiple challenges. From the design of the piston through the specification of the material and the development of the appropriate printing parameters, we had to make many fine adjustments to achieve the optimum result,” explains Volker Schall, Head of Product Design in Advanced Engineering at MAHLE. “We have now not only mastered the technical side of things, but can also assess how the method can be embedded into existing manufacturing processes.”
High quality confirmed in stringent test runThe piston blank is then finished, measured, and tested at MAHLE and must meet the same strict standards as a conventionally manufactured part. Special attention is paid to the central area of the piston—known as the skirt—and the point at which it connects with the conrod—the pin bore. These areas are subjected to skirt pulsing and tear-off tests; MAHLE’s engineers can thus simulate the loads that will occur during future operation.
In addition to cutting open pistons for analysis, project partner Zeiss carried out numerous nondestructive tests using procedures including CT scanning, 3D scanning, and microscopy. The results show that the printed piston achieves the same high quality standard as a conventionally manufactured production piston. When it came to practical testing, six pistons were fitted in the engine of the Porsche 911 GT2 RS, and the drive unit successfully completed 200 hours of endurance testing under the toughest conditions on the test bench. This comprised around 6,000 kilometers at an average speed of 250 km/h including refueling stops, and around 135 hours at full load. The test run also included 25 hours of motoring load, i.e., the simulated overrun mode of a vehicle.
Additional charge air cooler for even greater efficiencyFurther evidence of the advantages of 3D printing is provided by an additional charge air cooler, again developed as part of the joint project with Porsche and Trumpf. Hidden in an air pipe between the turbo and the original charge air cooler, this additional component benefits from a significantly larger heat transfer surface thanks to the possibilities opened up by 3D printing. This allows flow control and cooling to be optimized, resulting in cooler intake air, increased engine performance, and lower fuel consumption.
MAHLE is strategically expanding its competence in 3D printing MAHLE is set to harness the potential of new production processes, such as 3D printing, for further projects and aims to expand its competence in this area specifically. Shorter development and production times present a great advantage. This is particularly true when it comes to new technologies such as e mobility, where thermal management components with complex structures are needed to provide cooling and air conditioning in electric vehicles, motor or transmission housings, and battery systems. Further examples include optimized components in the periphery of the motor, such as air pathways, filter housings, and oil management components.
Areas of need have also been identified with regard to the development of small lots and the production of discontinued components to supply the aftermarket for historic vehicles. Other promising fields of application involve rapid prototyping, i.e., the quick construction of parts for testing, and reverse engineering—the reproduction of components from a 3D scan.
About MAHLEMAHLE is a leading international development partner and supplier to the automotive industry as well as a pioneer for the mobility of the future. The group’s product portfolio addresses all the crucial issues relating to the powertrain and air conditioning technology—both for drives with combustion engines and for e mobility. In 2019, the technology group generated sales of approximately EUR 12.0 billion with more than 77,000 employees and is represented in over 30 countries with 160 production locations.

MAHLE steers steady course through coronavirus crisis

Stuttgart, April 30, 2020 – In the current coronavirus crisis, the MAHLE Group can rely on a sound financial position and liquidity. In the 2019 financial year, the automobile component supplier intensified its strategic and technological realignment despite challenging conditions. MAHLE recorded the largest volume of orders received in the history of the Group, with orders running into the billions in the field of new technologies alone. The technology group now has an unmatched broad-based portfolio for the various types of drive system. Dependence on the internal combustion engine for motor vehicles has now fallen almost to the 40 percent mark. Despite the current crisis, MAHLE remains on track for the future and is consistently forging ahead with its efficiency improvement programs. Intensive preparations are now underway for the resumption of production at the Group’s European plants.

There was a drastic fall in sales in March and April and 2020 will be an extremely difficult year for MAHLE,” said Dr. Jörg Stratmann, CEO and Chairman of the MAHLE Group Management Board at the Annual Press Conference in Stuttgart on Thursday. “The MAHLE Group has a sound financial position. This is why we can survive a crisis for a certain time. It is our entrepreneurial responsibility to consistently continue our efficiency improvement programs and to maintain our strict cost discipline. This way, we will master the crisis.”
Following the almost complete closure of its plants throughout the world, MAHLE is now preparing intensively for the resumption of production in Europe. “We have delivery capabilities and are in a position to meet our customers’ demand. We remain a partner that is known and appreciated for its reliability,” said Jörg Stratmann.
The MAHLE CEO appealed to politicians to define conditions for the revival of the economy and the stimulation of demand in the near future with a view to safeguarding value addition and employment in Germany. “In my opinion, incentives offered for a limited period such as car purchase bonuses or a temporary reduction in value-added tax would be effective tools,” said Stratmann. “It is important to create perspectives for industry and consumers now.” Stratmann expressly calls for technology-neutral measures that address the market on a broad basis, i.e. not only electric vehicles and hybrid drives but also modern, economical gasoline and diesel vehicles.
The 2019 financial yearThe 2019 financial year was characterized by a decline in markets throughout the world. The MAHLE Group was not immune to this development. However, with an adjusted fall of 3 percent in sales to €12.0 billion, it performed better than the market as a whole, which suffered an overall decline of about 5 percent.
Despite the economic headwind and other challenging effects such as the fundamental transformation of the automotive industry, negative geopolitical impacts, the Brexit debate and a political environment with ambitious targets, MAHLE continued to pursue its strategy consistently last year. In 2019, the fall in sales, the continued high investments in research and development, operational issues and high accruals for restructuring led to a consolidated net loss of about €212 million. “Despite this temporary development, we continue to forge ahead with the realignment of MAHLE,” said Stratmann. “We are doing our homework to position our Group successfully for the future. We intend to play an active role in shaping change in our sector and to remain a successful market player and an attractive employer.”
MAHLE has clearly defined its goals for safeguarding its competitiveness; the further development of future-oriented technological fields, the improvement of productivity and profitability and the adaptation of the Group structure to the changed business environment.
In 2019, MAHLE implemented a comprehensive package of measures. The “Electronics and Mechatronics” business unit was newly established with effect from January 1, 2020 in order to pool the competences of the Group in these fields of technology and to focus even more strongly on the development and production of electric motors as well as electronic and mechatronic systems. The Group maintained investments in research and development unchanged at a high level. The cost saving programs in various business areas of the Group achieved their interim targets in 2019.
About MAHLEMAHLE is a leading international development partner and supplier to the automotive industry as well as a pioneer for the mobility of the future. The MAHLE Group is committed to making transportation more efficient, more environmentally friendly, and more comfortable by continuously optimizing the combustion engine, driving forward the use of alternative fuels, and laying the foundation for the worldwide introduction of e-mobility.

Press release [PDF; 145 KB]Press picture [JPG; 1420 KB] MAHLE Powertrain presents new prototype 48-volt batteryIncreased charge and discharge rates enable significant savings potential thanks to optimized battery cooling and cell chemistryMild-hybrid vehicles need to recover energy efficiently and at a relatively high power during deceleration events. High storage capacity is not required for these applications as the recuperated energy can be deployed during the next acceleration. Thus a compact and cost effective battery that is capable of high charge and discharge power levels relative to its storage capacity (high Crates) is desirable. As there were no suitable low-cost, compact batteries able to deal with the necessary recharge and discharge cycles involving high currents, MAHLE Powertrain decided to develop its own. The LTO chemistry in the selected cells allows continuous charge / discharge rates of 10 kW and peak rates for short periods up to 20 kW from a battery pack that has only a 0.5 kWh storage capacity.
Optimal battery cooling guarantees charge/discharge performance and battery durability. However, the coolant needed to be electrically isolated from the cells. MAHLE Powertrain settled on a robust cooling strategy, with simulations showing cooling performance to be exactly on target.
MAHLE Powertrain engineers paid a great deal of attention to the design of the busbars and electrical connections within the battery, as any high resistance in these components can be an additional heat source and limit the power capability of the system.
Testing of the first prototype is underway to verify that the pack can meet the performance targets. Initial results indicate that all temperatures within the pack remain within an acceptable range at a continuous discharge rate of over 10 kW and that it is capable of peak power levels in excess of 20 kW. The next step will be to install the prototype pack into MAHLE Powertrain’s 48V eSupercharged extreme downsizing demonstrator vehicle.
