How to Get Started in 3D Printing: Career Paths and Industry Insights

Did you know the first 3D printer was invented in the 1980s? It’s true – but recent innovations have made it more mainstream, which is why many people had no knowledge of 3D printing prior to the last few years. 

So, what exactly is 3D printing, how does it work, and how can you get started in this expansive field? Let’s explore, starting with the basics.

How do 3D printers work?

3D printing is an additive manufacturing process that builds objects layer by layer, creating items by adding materials rather than removing them. 

This is in contrast to subtractive manufacturing techniques, such as CNC machining, laser cutting, drilling, or sawing, where objects are created by removing material in order to create the desired product. 

3D printers use plastic, resin, stainless steel, nylon, silver, or polycarbonate to create tangible parts and products based on digital instructions.

What can 3D printers make?

The versatility of 3D printing means that it is used in a wide variety of industries, including automotive, aerospace, construction, consumer products, dental, engineering, healthcare, and more.

3D printers have been used to make:

  • Eyeglasses
  • Furniture
  • Aerospace prototypes and parts
  • Dental prosthetics
  • Orthotics
  • Car parts
  • Medical devices
  • Footwear
  • Custom toys and home decor

Research and development is one of the most popular areas of application for 3D printers, so the variety of industries using 3D printing and the parts and products they produce will continue to grow as innovations are made.

What 3D printing is used in manufacturing?

Various types of 3D printing are used in the manufacturing process, including:

  • Fused deposition modeling, which uses melted filaments to create an object
  • Selective laser sintering, where a laser is used to fuse powdered materials
  • Direct metal laser sintering, which uses a laser to melt and fuse metal powder
  • Stereolithography, which uses a liquid polymer
  • Digital light processing, where photosensitive liquid resins are used
  • Polyjet, which uses liquid photopolymers

The process chosen depends on the material being used, as well as the desired outcome. Regardless of the process, 3D printing is optimal for prototyping or creating replacement parts when only a few are needed. It’s also an excellent option for manufacturing complex parts that are more difficult to create with other methods.

For high quantities, traditional manufacturing methods are usually still preferable.
