There are so many people around the world who are in dire need of prosthetic limbs. Developing countries are the most affected regions where amputations are caused by anything from traffic accidents, land mines, diseases like diabetes, tumors, and infections. More
In some cases, a person may have been born with a missing leg or arm, leaving behind a void that can only be filled by a prosthetic limb. Unfortunately, there is a stack shortage of experts, materials, and prosthetic centers that can produce enough of these limbs to meet the overwhelming demand.
Using a 3D printer to print construction structures layer-by-layer. To demonstrate the technology, researchers and entrepreneurs have off-site printed bridges in metal, concrete or polymer, and entire buildings in concrete or clay on-site. More
Construction 3D printing is a method for manufacturing construction elements or entire buildings by means of a 3D printer printing concrete, polymer, metal, or other materials, layer-by-layer. The most common type of printer is based on a robotic arm that moves back and forth while extruding concrete. Other methods for 3D printing include powder binding and additive welding. Powder binding is 3D printing within a basin of powder, solidifying powder layer-by-layer to create the desired object. Additive welding has been demonstrated by printing a full-scale, functioning metal bridge in Amsterdam.
With the help of veterinarians, 3D designers, and a local artist, Freddy the tortoise was able to receive a hand-painted, 3D-printed hull after losing most of her shell in a devastating forest fire. Freddy was found after the fire left him with burned forelegs and a damaged hull. Freddy had lost 85 percent of her shell, and over the next months, it continued falling off. Cicero Moraes told Inside Edition that his team decided to create the world's first 3D printed hull for the animal.
