Metal laser melting technology is increasingly important in the aircraft industry. Shorter lead times, more suitable parts and unprecedented freedom of form are important reasons for choosing this technology.
Today, the technology's outstanding performance in aircraft "lightweight structure" and "bionics" makes this trend even more obvious: metal laser additive manufacturing technology is changing its design thinking. In future aircraft designs, the components will be able to absorb the lines of force in a targeted manner. At the same time, it meets the requirements of lightweight. Durable, resource-saving, and cost-effective structure, so that fish and bear's paw can have both.
Mr. Frank Herzog, founder and CEO of ConceptLaser Ltd., Mr. Peter Sander, Head of Emerging Technologies and Concepts at Hamburg Airbus, and Professor Claus Emmelmann (Engineering Ph.D.), CEO of Hamburg LaserZentrumNord GmbH, participated in the connection of the Airbus A350XWB. Development and production of the 3D metal printing project for the cradle. Previously, the part was milled from aluminum. Now, it can be printed with titanium material, and the weight loss is more than 30%.
The connection of the Airbus A350XWB was produced in 3D printing and was selected as the finalist of the 2014 German Economic Innovation Award in 2014. The assessment opinion of the jury is that this cross-industry development form has completely changed the way of manufacturing aircraft components and the “lightweight†approach of civil aircraft. In December 2015, the three members of the project participated in the “2015 German Future Award†held in Berlin, Germany, and were jointly awarded the “Best Team†honorary title and accepted the honorary certificate issued by the German President himself.
The argument for supporting the use of metal laser melting technology in aircraft manufacturing is freeform and weight reduction. The “lightweight†feature can help airlines achieve more economical results in aircraft operations. The weight reduction effect that the fixed element (bracket) can achieve will help achieve lower fuel consumption or increase the load capacity of the aircraft.
When designing a new aircraft, thousands of small-scale FTI (flight test installation) brackets are required. The MetalManufacturing method not only helps designers quickly produce new designs, but also produces parts that are 30% lighter than conventional cast or milled parts.
In addition, the metal laser additive manufacturing process is based directly on CAD data, omitting the mold, reducing costs, allowing parts to be put into use at a faster rate, saving up to 75% of the time. At the same time, the use of this process without the characteristics of the mold, in the early stage can be produced with prototypes close to the characteristics of mass production parts, greatly saving mold costs.
Aircraft parts produce up to 95% recyclable waste during milling. With laser melting technology, the operator can not only get "parts close to the final contour", but also waste material is only about 5%. “In the aircraft industry, it is called “buytofly ratioâ€, 90% is a remarkable value here. This value certainly shows a positive side when measuring energy efficiency.†Professor Claus Emmelmann (Engineering PhD) said. This approach is especially attractive when applied to advanced and expensive aircraft manufacturing materials such as titanium.
