Researchers use 3D printing technology to create an ivory substitute

Now, a group of researchers have invented a new synthetic ivory that can be used to repair or restore historical objects - from lost chess pieces to 17th century coffins. It is reported that this synthetic ivory called Digory is made of synthetic resin and calcium phosphate particles.iqiTextile Testing Instruments, Testing Equipment Manufacturer

The Vienna Institute of Technology stated in a statement on Tuesday, quot;It is processed in a hot liquid state, then cured with ultraviolet light in a 3D printer, and fully forms the desired shape. Then, it can be polished and color matched to create a seemingly realistic ivory substitute.quot;iqiTextile Testing Instruments, Testing Equipment Manufacturer

Repair experts have started using plastic, bones, and other substitutes to replace ivory, but finding materials that look, feel, and behave like ivory has always been a challenge. quot;This material should not only look like ivory, but its strength and stiffness must also be correct. Additionally, this material should be machinable,quot; said Thaddaa Rath of the Vienna Institute of Technology. It is reported that he is the main author of the paper that published this study.iqiTextile Testing Instruments, Testing Equipment Manufacturer

It is understood that the research team came up with the idea of developing Digory to help repair a 17th century coffin that lacked exquisite decorative ivory fragments. The 3D printing method allows them to replicate the complex design of the original.iqiTextile Testing Instruments, Testing Equipment Manufacturer

In order to find the correct formula for synthesizing ivory, researchers conducted a series of experiments. It is reported that this synthetic ivory has semi transparent properties that mimic natural materials. In addition, it also has similar density and color. Researchers are fortunate to have found that staining Digory with black tea can match older ivory.iqiTextile Testing Instruments, Testing Equipment Manufacturer

Researchers hope that Digory can help restore historical art and religious artifacts in a fast, convenient, and ethical way.iqiTextile Testing Instruments, Testing Equipment Manufacturer
