Additive Manufacturing: Technology Metals and Manufacturing Processes

H.C. Starck is a leading premium supplier of the technology metals tungsten, molybdenum, tantalum, niobium, and rhenium, high-performance ceramics, and thermal spray powders with a long-established metallurgical and process-technical expertise.

Additive manufacturing, also known as 3D printing, is being seen as the technology of the future for manufacturing low-weight components with complex geometric structures and high stability.

It allows freedom of design to create objects in three dimensions, leading to entirely new ways of producing custom-made components and structural elements that are impossible to produce with conventional technologies.

H.C. Starck provides high-alloyed metal powder solutions under the brand name AMPERSINT® for the specific requirements of additive manufacturing processes like:

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

Spherical Powders Optimized for Additive Manufacturing

Using state-of-the-art processing capabilities, H.C. Starck now offers spheroidized refractory metal powders with tailored chemistry and particle size distribution. The company‘s core competencies – molybdenum, tantalum, niobium, and tungsten in pure and alloyed powder forms, will take advantage of this innovative process. (press release)
Spherical Powder Additive Manufacturing

Molybdenum and tungsten spherical powders optimized for additive manufacturing are engineered for enhanced processability and product performace 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. As a result, 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.
