At additive manufacturing (AM) exhibition Formnext 2018, Nov. 13-16, in Frankfurt, Germany, Sandvik (Sandviken, Sweden) will announce that it has substantially increased its capacity for metal AM by installing several new Renishaw RenAM 500Q quad laser machines. The company is also initiating further collaboration with Renishaw in areas such as materials development, AM process technologies, and post-processing.
This print capacity expansion follows a recently announced investment, amounting to 200 million SEK, in a new plant for the manufacturing of titanium and nickel powders for additive manufacturing, which will complement Sandvik’s existing Osprey powder offering to include virtually all alloy groups of relevance today.
The new multi-laser RenAM 500Q systems complement Sandvik’s existing AM machines, which include printers from EOS, Concept Laser, Arcam, and ExOne. As a collective, the machines now cover a wide range of printing technologies for different materials and applications.
When it comes to additive manufacturing, no two use cases are the same—the optimal balance of weight, strength, hardness, thermal characteristics, flexibility, geometric complexity, surface finish and other characteristics varies from one application to the next. Therefore, Sandvik works across the entire value chain, from component selection, AM design and modelling, through material choice/development and optimal printing process, to post-processing, testing, and quality assurance.
Kristian Egeberg, president of Sandvik Additive Manufacturing, said: “We refer to our process as ‘Plan it. Print it. Perfect it.’ Printing is only one of seven steps you need to master to obtain a perfect AM component. So, you have to think beyond printing to get the best possible value from additive manufacturing.”
“We work closely with our customers to tailor alloys in line with their exact requirements, even for small-batch print runs,” noted Annika Roos, head of the Powder Division in Sandvik. “Not only do we match the alloy to the purpose, we can also optimize the particle size for the chosen printing process.”
The AM customer cases Sandvik is set to display at Formnext 2018 in Frankfurt will showcase different materials, different AM process technologies and tailor-made post-processing methods. Exhibits will include coolant clamps for Seco Tools that are made from maraging steel and feature curved internal channels to improve cutter performance and lifespan. Also on display will be a Sandvik Coromant CoroMill 390 milling cutter. Made from titanium, the tool is up to 80 percent lighter and up to 200 percent more productive.
Further exhibits are set to include Varel nozzles manufactured from cemented carbide, which are not only printed on demand to reduce inventory but feature tailor-made threads that are tough enough for drilling in the oil and gas industry. Also on the stand will be sliding cases made from maraging steel for LKAB Wassara. The sliding cases are two-piece parts printed as a single unit—featuring internal channels—ready for underground hammer drilling with radically improved performance and increased service life.
Visitors to Formnext will find these Sandvik AM customer cases and a selection of Osprey powders in Hall 3.1, Stand C10.
