Occupational Safety Training for 3D Printer Operation

1. Overview of 3D Printers

a. What is a 3D Printer?

A 3D printer is a type of computer-controlled device used to create three-dimensional (3D) objects by building them layer by layer from consecutive materials. This process is commonly called “3D printing” or “additive manufacturing” and differs from traditional methods of machining or subtractive manufacturing, where items are typically made by cutting and shaping large blocks of material.

A 3D printer works by reading a 3D model from a digitized design file (usually created with CAD software) and then constructing the item by placing and solidifying layers of material, often plastic, metal, wood, or other materials. 3D printing technologies can vary, including Fused Deposition Modeling (FDM), Stereolithography (SLA), and Selective Laser Sintering (SLS).

The applications of 3D printing are diverse and have rapidly evolved from creating product prototypes to manufacturing components for aircraft and medical devices.
