A New Algorithm Found to Print the Impossible Objects by Using 3D Printers

The method that discovered; create a mathematical process before the 3D printing, it automatically calculates the object’s structure on desired data input. The team in Department of Computer Graphics and Algorithms led by Przemyslaw Musialski. They printed the object in the photo. To create the necessary geometrical needs for the object, the algorithm software calculates every aspect of the object such as; exact structure, hollow spaces and wall thickness. For the Turtle in the photo, the rotation axis of the turtle had to be precisely balanced to use as a spinning top, but for the fish, software has to adjust the exact structure and size to be floating in the position like the original one.

“Our method has a whole range of advantages,” Musialski explains. “It is fast, as the calculation is completed within seconds, it is resilient to errors, and as we proved, it can be used for many different optimisation processes compared to other methods.”

If you watched the video above, you saw the Cola bottle that oddly printed, and if you put water in the bottle it tips over but if it filled with alcohol it stayed in place. This result in the video happens because of the lower density of alcohol compared to the water. To achieve this result, the algorithm not only calculated the out shape, it also shapes the hollow space in the bottle. With this new algorithm, 3D printer users would be able to print technical spare parts or ornamental parts for their project. The algorithm software will ensure the object that user want to print will also feature the necessary physical properties.
