APA™ powders are particularly well adapted for additive manufacturing (AM) as they offer exceptional flowability, purity and batch to batch consistency.
- Superior flowability comes from the APA™ powders being highly spherical with minimal satellites. It allows for optimal spreading of the powder during the AM process. Highly spherical powders also improve packing in order to decrease voids.
- The APA™ process adds minimal oxygen. Impurities are also kept to the minimum as the wire is being atomized without any contact to hot surfaces. Starting with high purity low oxygen powders facilitates the production of parts that meet the desired chemistry and physical properties while allowing the recycling of the powder in order to maintain a low waste factor.
- The AP&C process is a very stable process that can meet narrow specifications and deliver the same powder properties from one batch to another. This is critical as the manufacture of parts using AM is sensitive to deviations in particle size distribution, chemistry, internal porosities, satellite presence and particle shape.
AP&C powders are being used on the majority of additive manufacturing technologies and meet the most stringent requirements in the market.
Laser Sintering and Selective Laser Melting Technologies
There are many laser-based additive manufacturing technologies with hundreds of systems installed worldwide.
AP&C powders can be used on most of these technologies. Laser sintering and melting technologies normally use fine particle size distribution powders (10-45 μm, 15-45 μm, 25-45 μm) that offer good flowability and purity. AP&C indeed offers these tailored particle size distributions. Technical data on these powders are available in the product section. Please contact us if you need more information.
Electron Beam Melting (EBM) Technology
EBM has been commercialized by Arcam AB since 1997. It is a high productivity solution that is used in aerospace and biomedical applications. There are more than 125 EBM systems in use over the world. EBM technology requires coarser powders (45-106 μm) with exceptional flowability and purity. AP&C has been supplying powders to Arcam AB EBM systems since 2007. Technical data on these powders are available in the product section. Please contact us if you need more information.
