Abstract: The application of structured light (SL) techniques has achieved remarkable success in three-dimensional (3D) measurements. Traditional methods generally calculate SL information pixel by ...

According to the National Institute of Standards and Technology (NIST), researchers have found special atomic patterns called quasicrystals in 3D printed aluminum alloys ... is made of a few identical ...

The quasicrystals found in this study form the corners of 20-sided shape called an icosahedron ... The alloy formed under the extreme conditions of metal 3D printing, a new way to make metal parts.

Abstract: Point cloud classification, crucial for discriminative 3D shape analysis, has witnessed significant progress through the application of deep learning. A significant research focus has been ...

One layer at a time, the laser melts the powder into a solid shape. 3D printing creates shapes that would be impossible with any other method. For example, in 2015 GE designed fuel nozzles for ...

One layer at a time, the laser melts the powder into a solid shape. This 3D printer builds objects by melting a fine metal powder with a laser. First, the surface is coated with metal powder. Then, a ...

The film explores different geometric shapes, focusing on cylinders, rectangular prisms, and pyramids. It describes the properties of each shape, such as the curved surface of a cylinder ...

It details the formulas used to calculate their volumes, emphasizing the relationships between these shapes. For example, the volume of a pyramid is one-third that of a prism with the same base ...
