DESIGN TIP: Metal 3D Printing Redefines Part Design

Metal 3D printing is helping to redefine part design, with capabilities to build ever-increasingly complex parts in less time and with little human intervention. Welcome to the industrial-grade 3D printing process of direct metal laser sintering (DMLS), which is the focus of our monthly design tip.

Med device developers are turning to industrial-grade metal 3D printing to produce a variety of prototype and end-use parts, including these components used for surgical instruments.

Through additive manufacturing technology, DMLS produces fully function metal prototypes and end-use parts, simplifies assembly by reducing component counts, offers virtually unlimited complexity with no additional cost, and works for a variety of industries, including the med device space (see part photo).

This month’s tip discusses:

  • A short overview of DMLS
  • Ways to avoid warping and curling with certain part features
  • Part orientation
  • Wall thickness considerations
