HP Multi Jet Fusion is a 3D printing technology developed by HP (Hewlett-Packard) that combines thermal energy and binding agents to fuse material layers together to create a three-dimensional object. A dual carriage system separates the functions of writing and coating.   Therefore each function is separately optimized for performance and productivity.  The Hp technology can transform the properties of each volumetric pixel (voxel).  For example, the HP Multi Jet Fusion 3D printers can print each voxel in a different color.  HP expects to make millions of colors available for 3D printing.  Other than color, HP expects to be able to control other properties, for example, opacity, conductivity, surface roughness, strength, and elasticity, to name a few.

The process involves spreading a thin layer of material powder, typically nylon, over a build platform. The printer then applies thermal energy to the powder bed, causing the particles to fuse together in the desired pattern. The printer then applies a binding agent to the fused layer, allowing subsequent layers of powder to adhere to it. This process is repeated layer by layer until the final object is complete.

The technology is known for its ability to produce parts with high precision and detail, as well as for its ability to print multiple parts at once. It is commonly used to produce small- to medium-sized parts, such as mechanical components, medical devices, and consumer goods. Additionally, the technology can print in various colors and finishes, making it a popular choice for prototyping and small-batch production.

3D Printed Aircraft

——————————

Engineers at University of Southampton in the UK have designed and 3D printed the world’s first 3D printed aircraft called SULSA (Southampton University Laser Sintered Aircraft).  All parts of the aircraft except an electric motor are 3D printed.  In July 2015, HMS Mersey, a vessel of the British Royal Navy launched the 3D printed aircraft as an exercise.  The 3D printed aircraft weighs 3 kgs and has a wingspan of 1.5 meters.  The aircraft is printed in four parts and can be assembled easily.  The aircraft carried a video camera to record its flight.  SULSA can be 3D printed for a cost of few thousand dollars.  SULSA demonstrates the ability to quickly 3D print aircrafts on and use them for short missions.
