From digital code to physical matter: the mechanics of additive manufacturing

How 3D Printing Actually Works · 8:25 · Video: History of Simple Things · Watch at the source

In short: Explore how 3D printing transforms abstract designs into physical objects. This video breaks down the entire production pipeline, from the initial software models to the diverse materials used in modern manufacturing.

The process begins with a digital design, typically a CAD (Computer-Aided Design) model. This model is processed through slicing software, which translates the 3D shape into a series of instructions for the printer to build the object layer by layer.

The technology is versatile, utilizing various methods such as molten filament, lasers, and resins. These techniques allow for a wide range of applications, including the creation of prosthetics, tools, art, and even 3D-printed homes. It also holds significant potential for future space exploration, such as preparing for life on Mars.
