In the human body, magnesium is an essential mineral that actually helps maintain the structural integrity of bones. It also degrades quickly when exposed to oxygen, water, and salts, all of which are abundant in the body.

According to assistant professor at the University of Nebraska-Lincoln, mechanical and materials engineering Michael Sealy, “Instead of having these permanent metal implants, let’s have one that degrades over time. Let’s eliminate this whole idea of a second surgery to have these implants removed. Instead of peening as a surface treatment, where I just hammer my outer surface, I’m going to print so many layers, and then hammer it, and then print a few more layers, and then hammer that,”

The 3D Printing Kinematics Dress Design

Posted on Updated on

The 3D Printing Kinematics Dress Design.
We can boost our knowledge with 3D printing technology.
According to Cooper Hewitt, “New technology for kinematics dress design and 3D-Printing Process.
The Kinematics dress represents a new approach to manufacturing in which design, engineering, customization, and simulation are part of one seamless system, so that the object, once fabricated, is fully finished and complete”.

3D Printing with plants

Posted on Updated on

3D Printing with plants. According to Oak Ridge National Laboratory Scientists team and ORNL’s Amit Naskar,” They created a new material with excellent printability and performance by tapping into lignin—a key component of plant cell walls that provides sturdiness. Lignin is a current byproduct of the biofuels process that could become a valuable coproduct with this new use. The method combines lignin, rubber, carbon fibre and acrylonitrile butadiene styrene, or ABS—commonly used in plastic toys—to 3D print structures with 100 per cent improved weld strength between the layers over ABS alone. To achieve this, we are building on our experience with lignin during the last five years. We will continue fine-tuning the material’s composition to make it even stronger.”
