Abstract

Scientists have created a way to 3D print glass, which opens up the door to more precise medical and nano technology.

Concept

• Makes glassware more accessible by enabling people to print their own items
• Allows for more precise production of small parts (i.e. medical equipment)
• 3D printed glassware has the potential to be cheaper to produce
• 3D printed glass is biodegradable, strong, and ecologically friendly

How does it work?

• "Nanoparticles of quartz glass are mixed with a tiny amount of liquid polymer.
• The mixture is cured at certain points by ultraviolet light using stereolithography.
• This makes those locations harden while the rest of the material remains liquid, essentially building up the shape of the object one layer at a time.
• The object is then washed in a solvent bath and heated to form a fully fused and strong structure" - Megan Treacy

Why does this matter?

This technology advances the fields of optics, data transmission, and biotechnology through highly customizable and accessible glass parts as well as being able to print things that currently don't exist or can't be made by hand.

As the ability to 3D print glass becomes more accessible it may decrease the use of plastics which is better for the environment.
