What is 3D Printing?
- Developed in the 1980s, 3D printing gained widespread attention in the 2010s, with many predicting it would revolutionize manufacturing. Initially, the technology was costly, slow, and prone to errors, limiting its application.
- Recent advancements have addressed many of these limitations, making 3D printing more accessible and widely used.
- 3D printing is also called additive manufacturing and it builds three-dimensional objects from digital models by layering materials.
- Unlike traditional methods that remove material to shape an object, this process adds material, such as plastic, composites, or bio-materials, layer by layer.
- This method allows for efficient, customized production with varied shapes, sizes, and colors.
Applications and Examples of 3D Printing
- Healthcare: During the COVID-19 pandemic, 3D printers were used to produce critical medical supplies like swabs, masks, face shields, and ventilator components.
- Automobile and Aerospace: In May 2023, Relativity Space, an aerospace company, launched a 100-foot-tall test rocket made entirely from 3D-printed parts.
- Although the launch was innovative, the rocket experienced a failure shortly after liftoff.
