3D printed heart made from porous material holds promise for prosthetics, robots

Cornell researchers have developed a new lightweight and stretchable material with the consistency of memory foam that has potential for use in prosthetic body parts, artificial organs and soft robotics. The foam is unique because it can be formed and has connected pores that allow fluids to be pumped through it.

New Antimicrobial Composite Resins Make Possible 3D-Printed Teeth that Kill 99% of Bacteria

Researchers at the University of Groningen in the Netherlands have created a process that can manufacture 3D-printed teeth and braces which are actually good for your other teeth, and dental health in general.

3D-Printable Antimicrobial Composite Resins [paid PDF access] outlines the development of the new plastic resin used in the process, which involves embedding antimicrobial quaternary ammonium salts inside extant dental resin polymers. Because the salts are positively charged, these disrupt negatively charged bacterial membranes, resulting in them bursting and dying. The mixture was then hardened with ultraviolet light.

Discov3ry Extruder Launches Kickstarter Campaign to 3D Print in Silicone, Wood Filler, Conductive Paint & More

3D printing has been around for years, but just recently has the consumer market really begun to take off. Like all new technologies, there are many limitations. One of the biggest limiting factors of consumer level 3D printing today, would probably be the restrictions we face in terms of printable materials.
