Study Notes
Additive Manufacturing
- Also known as 3D printing, another term for additive manufacturing is direct digital manufacturing.
Comparison to Subtractive Manufacturing
- Additive manufacturing differs from subtractive manufacturing in that it creates objects by adding material incrementally.
Industry Impact
- The manufacturing industry considers additive manufacturing as the beginning of a potential third industrial revolution.
File Formats
- STL is a file format commonly used to define the surface geometry of the solid model in additive manufacturing.
Drawbacks
- A drawback of additive manufacturing is higher costs for large production runs.
Direct Energy Deposition
- The primary energy source used in direct energy deposition technologies for metallic materials is laser or electron beam.
Process Flow Protocol
- The process flow protocol that involves cutting the model into many horizontal layers is called slicing.
Industry Applications
- Architecture has seen the application of 3D printing in creating scale models of buildings.
- Bioprinting is the term used for the growth of organs by 3D printing of human tissue.
- Fashion envisions the possibility of wearing 3D-printed, custom-made clothing in the future.
