3D Printing News
3D printed ovaries lead to successful births in mice. 3D bio printing has a bright future, although many of the much talked about implementations are decades away from being implemented in humans, this is a high potential new technology area.
A research team at the University of Minnesota made a 3D printer that uses silicone and four nozzles to 3D print a stretchable skin which could have robotics and wearables applications.
Yet another advance in soft robotics, this soft robot can walk on sand. Soft robotics uses soft materials for motion by making flexible pneumatic muscles for example. The combination of soft robotics and 3D printing is leading to a lot of new research in new kinds of robots currently.

3D Printing Research and Patents
Fused Deposition Modeling is currently being considered for a lot of manufacturing applications, this paper where the team looks at optimizing the dimensional accuracy of FDM prints is therefore surely welcome.
Directed Energy Deposition has been around for a long time through its precursor welding technologies. This paper looks at how post processing affects tensile strength in titanium DED 3D printed parts. Since this technology is being increasingly used for structural components in aircraft this paper will find some curious readers.
Functionally graded materials (or gradient materials) are materials whereby the structure of the material is altered across a gradient to give the material or final part different properties in different areas. One area could be more flexible for example while another is more brittle. In this paper Optomec’s LENS technology is used to make a functionally graded internal fracture plate. The fracture plate was printed so it was less flexible at its center and more flexible at its ends so that it could better fit with the surrounding bone. Gradient materials will have big impacts on engineering because you can now essentially design a material for a particular application or custom design the material of one part to improve its functionality.
This paper looks at three different methods for 3D printing bone and tendons.
