Manufacturing Process

Mixing Phase

  1. Weigh all metal powders accurately as per the formulation.
  2. Blend the powders in a high-shear mixer to ensure homogeneity.
  3. Incorporate magnesium aluminate, silicon carbide, and graphite powders gradually while mixing.

Drying and Screening Phase

  1. Dry the mixed powder batch in a controlled oven at a temperature of 80°C for 2 hours.
  2. Sieve the dried powder through a mesh size 150 to ensure controlled particle size distribution.

Deoxidation Phase

  1. Place the sieved powder in a vacuum furnace at 150°C for 1 hour to reduce oxygen content.
  2. Cool the powder gradually to room temperature under an inert gas environment to prevent oxidation.

Final Blending Phase

  1. Blend the deoxidized powder with an anti-caking agent for 30 minutes.
  2. Conduct a final screening through a mesh size 200 to ensure optimum flowability.

Usage Instructions

Use this powder with compatible 3D printing equipment, ensuring proper temperature settings for effective melting and layering. Store any unused powder in a dry, cool place to maintain quality.
