What is Additive Manufacturing?
Additive manufacturing, commonly known as 3D printing, is a process of creating three-dimensional objects by building them layer by layer from a digital model. This technique allows for the fabrication of complex and intricate structures that would be challenging to produce using traditional manufacturing methods.
How Does Additive Manufacturing Apply to Nanotechnology?
In the context of
nanotechnology, additive manufacturing can operate at the nanoscale to create highly precise and functional materials and devices. This involves manipulating materials on an atomic or molecular scale to achieve desired properties and functionalities. The integration of additive manufacturing and nanotechnology opens up new possibilities for
advanced materials, electronics, and biomedical applications.
