Metal 3D Printing

3D printing or additive manufacturing is a method of manufacturing parts directly from a digital model using a layered material construction approach. These materials take the form of powders, and the laser works one layer at a time through the powder to form an object. Metal, plastic, and glass are some of the most important materials used to create a powder. The selected material passes through a super powerful crusher until it is a form of powder. This tool-free manufacturing method can produce fully dense metal parts in a short time, with great accuracy as shown in Figure 1. 

Using 3D modeling to create prototypes has become standard across manufacturing industries i.e., for aviation, oil and gas, marine and automotive applications. This method is also very useful for making small, complex, low-volume metal parts such as medical, jewellery and dental parts.

The main benefits of 3D printing are:

  • Ability to design geometrically complicated pieces.
  • Lower manufacturing costs.
  • Ability to fabricate parts without tools.
  • Get products on the market quicker.
  • Replacement of inefficient manufacturing workflow.
