Additive Manufacturing H.C. Starck’s Broad Portfolio of Products and Services

Additive manufacturing (AM), also known as 3D printing, has been discovered as a real “game changer” because it opens completely new possibilities for many industries. The innovative technology leads to entirely new ways of manufacturing custom-made components and highly complex elements that have been unthinkable to produce with conventional technologies before.

H.C. Starck offers 3D printing technology metals and their alloys as well as services to support its customers to fully benefit from the unique advantages of Additive Manufacturing.

Our powders are engineered for the whole range of additive manufacturing processes, including:

  • Selective Laser Sintering (SLS)
  • Laser Beam Melting (EBM)
  • Laser Metal Deposition (LMD)
  • Electron Beam Melting (EBM)
  • Direct Metal Deposition (DED)
  • Direct Metal Laser Sintering (DMLS)
  • Rapid Prototyping (RP)
  • Rapid Manufacturing (RM)
  • 3D Printing (3DP)

Spherical Refractory Metal Powders Optimized for Additive Manufacturing

Based on 100 years' experience in manufacturing and development of refractory metals, H.C. Starck has developed spheroidized refractory metal powders with tailored chemistry and particle size distribution, perfectly suited for additive manufacturing technology. The company‘s core competencies – molybdenum, tungsten, tantalum and niobium in pure and alloyed powder forms, will take advantage of this innovative process. 

Spherical Powder Additive Manufacturing

Spherical Tantalum and Niobium Powders

Refractory metals like Tantalum and Niobium are very robust and unique materials with both exhibiting high melting points, high corrosion resistance, excellent chemical resistance and biocompatibility. Due to their good thermal and electrical conductivity they are suitable for a wide range of high-tech applications.  

The combination of the unique versality of gas atomized AMPERTEC® Spherical Niobium and Tantalum Powders from H.C. Starck Tantalum and Niobium GmbH with the outstanding design freedom of Additive Manufacturing technology opens new application opportunities. 

Due to the highest transition temperature of Niobium and its excellent superconducting properties, the atomized AMPERTEC® Spherical Niobium Powder can be used in multifaceted-structure components requiring the highest degree of conductivity. The properties of AMPERTEC® Spherical Nb can be combined with the advantages of different Additive Manufacturing Technologies including but not limited to Laser Beam Melting, Electron Beam Melting, Laser Metal Deposition.  Due to its unique properties, AMPERTEC® Spherical Nb Powder can be for example applied in corrosion-resistant components and high-temperature applications in the chemical processing industries.

The AMPERTEC® Spherical Tantalum Powders open new possibilities in applications that  combine high corrosion resistance with design freedom. AMPERTEC® spherical Tantalum offers the right solutions where conventionally manufactured parts reach their limits, for example parts with highest purity and high performance like microreactors. In the field of medical implants the combination of high biocompatible AMPERTEC® Spherical Tantalum Powder with design freedom allows to create the best patient specific solutions.

Besides the pure elements of Ta and Nb, we provide also AMPERTEC® Spherical Ti-42Nb Powder . Mechanical parameters of 3D printed specimen with a low E-modulus (60GPa) at high strength (680MPa) reveal its potential as a solution for high performance applications that require the combination of high elasticity and high strength. Combined with the excellent biocompatibility of Niobium our AMPERTEC® Spherical Ti-42Nb Powder beats for example parameters of standard medical implant materials.   

Our broad expertise in manufacturing and development of Tantalum and Niobium powders makes H.C. Starck Tantalum and Niobium GmbH your ideal partner for development of new alloys suitable for AM processing for applications that depend on high quality, high purity powders.

Spherical Tungsten and Molybdenum Powders

Molybdenum and tungsten spherical powders optimized for additive manufacturing are engineered for enhanced processability and product performance when utilized with popular additive manufacturing techniques such as binder jet, directed energy deposition and powder bed fusion. The inherent spherical shape of H.C. Starck‘s powders results in improved flowability and high apparent density, while meeting the stringent purity level demanded by customer and application requirements.

Technologically advanced applications in industries like medical and industrial imaging, nuclear and thermo-nuclear energy, and various aerospace related components will benefit from the new molybdenum and tungsten spherical powders.

3D Printing Produces Finished Parts

In addition, H.C. Starck develops innovative finished products using technology metals - molybdenum, tantalum, niobium, and tungsten, and produced via additive manufacturing processes. In 2014, H.C. Starck entered an agreement with Rapid Prototype and Manufacturing (rp+m) to develop new materials, processes and products using additive manufacturing tools. (press release)
3d Collimator Additive Manufacturing

For example, by using additive manufacturing, a single-piece molybdenum or tungsten component for medical imaging equipment can be produced more efficiently and to the most exacting specifications. Also, additive manufacturing provides the capability to rapidly develop prototype products that extend to production levels.

With additive manufacturing, a product can be designed and a sample created in a fraction of the time compared to traditional manufacturing. A single-piece component made from molybdenum or tungsten can be produced without the previously required manufacturing steps. Production processes such as the pressing and sintering of powder, rolling, machining and assembly of components are eliminated, making it easier and faster to seamlessly deliver products to customers using additive manufacturing technology.

3D printed components can be made as a single, three-dimensional piece from a 3D model. For example by selectively depositing a liquid bonding agent to join the powder, one or more metal parts can be printed at once from various materials. Thus, H.C. Starck’s product portfolio can be expanded to include 3D lead-free products for collimators and anti-scatter grids for CT scanners, SPECT and gamma cameras.
