Subject Matter Experts

From our core business of providing scientific solutions to our clients, we have developed innovative products. Some are produced internally, and some have arisen from partnerships with other research organizations. 

For example, we build lab software solutions to help manage and streamline your labs data, and environmental testing products for a variety of applications. 

  • IntelliSEM is a powerful automated particle analysis system.
  • ParticleID is  a customizable cloud hosted web application used to identify foreign particulate matter and  assist with root cause investigations. 

Other products we create count particles and help keep the air and environment safe.

RJ Lee Group is a materials analysis laboratory and consulting company which serves many different industries. We offer scientific solutions such as industrial forensics services, laboratory and testing services, litigation support, and laboratory software to many industries:

Powdered Metals in Additive Manufacturing (AM) and Powder Metallurgy (PM)

Metal additive manufacturing and powder metallurgy, rely on the quality of powdered metals, feedstock material and the optimization of equipment and process parameters to yield the highest quality parts. Demanding applications such as aerospace, power generation, medical/dental and military, are particularly exacting, as defects or discontinuities could result in unpredictable or even catastrophic failure. For example, ceramic contaminants in metal powder feedstock can become incorporated into parts built using the AM powder bed fusion method, creating internal discontinuities that may concentrate stresses and contribute to fatigue crack initiation when the product is in service.
Feedstock quality assessment

RJ Lee Group offers an extensive array of analytical methods and techniques appropriate to each powdered metals sample, whether virgin and recycled feedstock material is used.

  • Powdered Metals (Laser or Electron Beam Powder Bed Fusion, or Directed Energy Deposition)
    • Composition
      • Bulk chemistry
      • Particle by Particle (PxP) using computer-controlled SEM
    • Dimensions
      • Particle size distribution (PSD)
      • Shape factors (aspect ratio, roundness, roughness) per ASTM F1877
      • Surface detail captured in PxP images
    • Contaminants
      • Cross-Contamination (particles of undesired alloy present in subject alloy)
