# video | You can print jewelry made from beautiful bacteria on a 3D printer

In one of our previous articles, wetalked about a project called Bacterial Art. Its authors create drawings from microbes and try to prove that the bacterial world is not so vile as it seems. Another proof of the beauty of microscopic creatures can be considered a scientific work conducted by scientists from the US state of Massachusetts. They developed a technology in which a gel layer with various bacteria is applied to objects printed using a 3D printer. Over time, figures glowing in the dark begin to form on the surface of three-dimensional figures. But how is this possible?

Items that glow due to the reaction of bacteria and chemicals

About new technology that can be usedwhen creating jewelry, it was told in the edition of New Atlas. By experimenting with various substances, scientists were able to create the so-called "hybrid living material." It is a mixture of two types of resins and gel actively used in 3D printing, consisting of bacteria grown in laboratory conditions of E. coli. Interactions with chemicals of one of the varieties of resins, microbes begin to glow in beautiful shades.

By printing on a 3D printer several items froma mixture of standard plastic and a chemical-impregnated resin, the researchers coated them with gel from pre-prepared bacteria. After some time, chemicals caused the reaction expected by scientists in bacteria and luminous patterns began to form on the outer shell of a product printed on a 3D printer. According to researchers, using other types of chemicals and bacteria, they can achieve an even greater variety of patterns.

Do you know how to detect defects in printed parts on a 3D printer?

In the future, this technology can be used.not only to create jewelry, but also for medical purposes. For example, 3D printers will be able to print medical instruments to detect dangerous bacteria. Just imagine - people will have the opportunity to see places contaminated with microbes in their house, walking through the rooms with a piece of plastic soaked with chemicals. If you bring such an object closer to a dirty place, the bacteria reacting to chemicals will immediately light up with bright colors.

In general, in the future we will see a lotdevices created using 3D printing. For example, recently, scientists from Singapore have developed real chocolate "ink" from which you can print delicious cakes and other sweets. You can read more about this in our special material.
