Harvard researchers 4D print the face of a new class of shape-shifting materials

4D printed, shape-shifting structures hold significant potential for the future of engineering. Be it self-assembling trusses, or medical devices that help inform cell regeneration, the field still has many challenges to overcome before its possibilities become practical. Up to now, one of the greatest challenges to 4D printing has been the ability to create complex, smoothly-curved shapes. […]

Harvard researchers develop SWIFT method to 3D print organ building blocks

Researchers from Harvard University’s Wyss Institute have developed a novel sacrificial ink-writing technique called SWIFT (sacrificial writing into functional tissue) to 3D print large, vascularized human organ building blocks (OBBs). Demonstrating its method, the team has created cardiac tissue that fuses and beats synchronously over a 7-day period. This enables the rapid assembly of perfusable […]
