3DWhat will the printed object look like after a long period of aging and erosion? Today, Magic Monkey is going to take a look at everyone.

want 3D There are other reasons why printed materials are kept longer than a few years, but our technology hasn’t been around long enough to really understand what happens to these items over time.
To find out, art conservation researchers at the Complutense University of Madrid in Spain examined two types of 3D The printed material undergoes accelerated artificial aging. As plastic ages, any damage to the material (such as loss of color or chemical changes) is usually caused by exposure to ultraviolet light or extreme temperature fluctuations. To simulate these extreme environments more quickly than natural aging, researchers will 3D The printed sample and the original filament are placed in two different chambers: one exposes the samples to UV light and the other subjects them to a range of high temperatures.
They tested two types of filaments 3D Popular materials for printing: Acrylonitrile Butadiene Styrene (ABS) and polylactic acid (PLA). For both, they tested a length of filament fed into the printer and a small rectangular piece of printing material. The study is titled “Using PLA and ABS 3D printing materials for fine art. Analysis of the composition and long-term behavior of raw filaments and printed parts“The article was published in”Cultural Heritage Journal“Newspaper.Links to related articles:
The test results show thatABS And PLA All showed chemical changes during rapid aging simulations. But among the two,PLA performance report IF Better. After UV radiation or temperature changes,IF The color is lost more and the structure of the material becomes more fragile and somewhat distorted. on the other hand,PLA Showing only very minor changes after UV irradiation, the material showed some bulges after being placed in the thermal chamber for some time.

It is to hope that 3D Useful for people who want to make their prints durable, it can also be useful if you want to develop more durable prints. 3D Printing equipment manufacturer. Still, there is much to investigate. There are others 3D The printed materials still need to be reviewed and further analysis needs to be completed. Of course, only time will tell how these materials will actually age.
