An Introduction To Metal 3D Printing

An Introduction To Metal 3D Printing

3D printing is a technique that creates objects layer by layer, giving shape to complex designs weren’t possible before. Also known as additive manufacturing, metal 3D printing uses powdered metals and lasers. In this introduction to metal 3D printing, you’ll find that metal 3D printing on a large scale is a method that can:

  • Make parts and systems lighter
  • Use more varied materials
  • Increase strength
  • Be customized with complex details that weren’t possible before
  • Speed up production
  • Produce lower quantities and large orders with equal ease
  • Do it all cheaper

So yes, 3D printing is kind of a big deal, and it’s still only getting started! Miller Plastics is at the forefront of metal 3D printing for prototypes, parts, and products, with a fleet of printers that can handle different projects with endless variations.

Industrial Uses

Below are some of the industries that use metal 3D printing today, but every day the list gets longer.

  • Aerospace (rocket parts and intricate mechanisms)
  • Automotive (race car prototypes)
  • Robotics (robotic arms)
  • Education (tools for complicated concepts and models for research projects)
  • Health care (custom prosthetics)
  • Dental (implants and appliances)
  • Medical (specialized surgical tools)
  • Jewelry (intricate casting)


While the potential applications are limitless, these are some of the most common materials used in 3D metal printing today.

  • Titanium, for its high strength-to-density ratio and resistance to corrosion
  • Aluminum, for its light weight and durability
  • Copper, for its high thermal and electrical conductivity
  • Stainless steel, for its strength, finish, and temperature resistance

Improving Technology

3D printing is still in its infancy, but it has already revolutionized many industries. 3D printing can make products with plastics and even food, but its future in metal is particularly promising. Future 3D metal printing technology will:

  • Reduce costs
  • Reduce the number of parts needed
  • Reduce the number of steps in the manufacturing process
  • Reduce waste
  • Increase production capacity
  • Increase customization
  • Increase quality
  • Increase speed to on-demand status
  • Increase options for materials

Miller Plastic Products has 50 years of experience in manufacturing, as well as the knowledge to capitalize on current technology and the ability to envision its future potential. We can create prototypes from sketches and drawings and see them through to production in the most efficient ways possible.
