Metal Printing

Make metal parts without tooling and for less cost than DMLS

  • Create cost-effective metal parts by eliminating tooling costs.
  • Stainless steel and bronze alloy provides strength and weight.
  • Ideal for small batch fabrication of metal parts for a fraction of the cost of DMLS/SLM.
  • Fits demanding aestetic and mechanical applications.
  • Available range of diverse finishes from polishes to plating.
  • Typical products include replacement parts for any industry, building and auto restoration, jewelry, and promotional products.
