Economic Dashboard

Explore the financial landscape of metal AM, from raw material costs to the critical break-even analysis against traditional manufacturing methods like molding.

Cost Per Part: 3D Printing vs. Molding

This chart illustrates the fundamental economic trade-off. 3D printing has no tooling cost, making it ideal for low volumes. Molding (MIM) has high upfront tooling costs, but becomes far cheaper per part at high volumes. The "break-even point" is where the lines cross.

Grand Challenges of In-Space Manufacturing

Printing in space is not as simple as launching a terrestrial printer. The entire process must be re-engineered to overcome fundamental physics challenges.

  • Microgravity: Surface tension dominates, causing molten metal to "ball up" instead of spreading evenly.
  • Vacuum: Creates a pure environment but causes material outgassing, which can contaminate sensitive equipment.
  • Radiation: High-energy particles can degrade material properties and alter crystalline structures over time.
  • Residual Stress: Locked-in stresses from printing can lower fatigue life and lead to premature failure under launch vibrations.
  • Qualification: Parts require extremely rigorous testing to prove the process is repeatable and reliable for mission-critical use.
