What Is 3D Printing Powder?

3D printing, or additive manufacturing (AM), is a popular manufacturing approach. This method generates three-dimensional objects layer-by-layer under computer control and possesses wide applications in healthcare, automotive, aerospace, etc.

3D printing powders are of great significance in the whole manufacturing process. You can find the trace of powders in binder jetting, powder bed fusion, sheet lamination, and directed energy deposition, all of which are essential divisions of 3D printing.

To ensure high-quality and repeatable AM powder production at large scales, powders have to meet the following requirements.

  • Particle Size Distribution (PSD): Smaller particles are preferred because they can form thinner and more delicate layers compared with those produced by larger particle powders.
  • Morphology: Regular-shaped powder particles with smooth surfaces are preferred because they can get well-packed particles and tougher components.
  • Flowability: Powder with better flow performance is preferable since flowability plays a key role in the formation of homogenous powder layers.

What Are the Benefits of Spherical Tantalum Powder?

Spherical tantalum powder is produced by atomizing molten tantalum using gas or liquid. This process creates a powder with a spherical shape, which has a uniform particle size distribution.

Spherical tantalum powder shares the following benefits with tantalum metal.

  • Impressive Thermal Performance: Tantalum has a high melting point of 2996°C, and it is highly conductive to heat, which makes it ideal for high-temperature applications.
  • Remarkable Chemical Stability: Tantalum is highly resistant to corrosion and can withstand harsh chemicals and environments. It can only be dissolved with hydrofluoric acid.
  • High Density: Tantalum has a high density of 16.6g/cm3, making it popular for applications that require a high mass-to-volume ratio.

In addition, spherical tantalum powder has several features that render it useful for 3D printing, including excellent flowability and uniform particle size distribution.

Advanced Refractory Metal (ARM) is a leading supplier of high-purity spherical tantalum powder for 3d printing tech because these particles have a uniform particle size, easy dispersion, high surface area, and great handling and flow properties.
