What are the flavors of 3D printing?
Additive manufacturing – specifically, 3D printing – has been around for a long time and has taken on many forms. The picture below illustrates the range of 3D printing technologies currently available.
The options with a green background are categorized as personal printers, and those with a pink background are classified as commercial printers. Besides the obvious and significant cost differences, commercial printers require highly trained operators and can produce objects made of metal and other exotic materials. The personal printers create objects using thermoplastics and photoresins. That’s not to imply that these plastic and resin-based objects are fragile. They’re not, but they do have a more limited range of applications.
Personal printers come in two forms: FDM (short for Fused Deposition Modeling) and SLA/DLP (short for Stereolithography Apparatus or Digital Light Processing). FDM printers use rolls of thermoplastic filaments, while SLA/DLP printers use bottles of photosensitive resins.
While SLA/DLP printers can produce objects with very high resolution, the objects are typically small, and the resins are expensive and toxic.
For the purpose of designing and creating assistive technology devices, FDM printers are the best choice.
