Selecting Patterns

3D Printing provides the quickest process for crating a pattern for duplication in one or multiple quantities.

Benefits:
  • Quick lead time.
  • Economical for small lots
  • Can be used for investment, sand or plaster casting.
  • No large tooling costs.
  • Can be used for small and large parts.
Applications:
  • Urethane Castings
  • Investment Castings
  • Sand Castings
  • Plaster Castings
  • Blow mold patterns
  • Epoxy mold patterns

Using a pattern

Steps in the Pattern use:

  1. A 3-D printed  object is created for the pattern.
  2. The pattern is finished to the texure or other finish as required.
  3. The pattern is in-cased in the mold material, which could be rubber, epoxy or ceramic.
  4. The pattern is removed from the mold by cutting the mold open or burning or melting the pattern to form the mold cavity.
  5. This cavity is filled with the final part material and allowed to solidify.
  6. The part is removed from the mold for final finishing if required.

Pattern Materials
