Thanks to MIT and Harvard brains can now be 3D printed by the pixel

A collaboration between MIT’s Mediated Matter Lab and the Wyss Institute for Biologically Inspired Engineering at Harvard University has yielded an image processing method that makes 3D printing patient-specific medical models a cinch. While accurate, and ready-sliced for 3D printing, manually processing MRI and CT scan data is a laborious process, typically done over the course […]

Harvard 3D prints robots embedded with sensors that react to objects like humans

Researchers from Harvard University have developed a method for creating soft robots with embedded sensors capable of sensing movement, pressure, touch, and temperature.  Inspired by the human “somatosensory system”, that gives us our physical abilities, the joint project between the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute for Biologically Inspired Engineering […]

Harvard’s hybrid 3D printing method creates electronic second skin

The future of wearable technology envisions smart devices worn as close to the human skin as possible. Activated by “soft”, flexible electronics, this kind of second skin will enable seamless interaction between wearers and their technology, enhancing the human ability to make decisions and perform tasks. Using a hybrid 3D printing method, researchers at Harvard […]

Harvard-MIT liver chip narrows gap between in vitro and in vivo drug tests

3D bioprinting, microfluidics and hydrogel scaffolding combine in the latest liver tissue research by a team of scientists attributable to seven institutions from across the globe. Centralized at Harvard Medical School and the Harvard-MIT Division of Health Sciences and Technology at Massachusetts Institute of Technology (MIT), the organ-on-a-chip device seeks to improve the way drugs are […]

3D printable nanocrystal ink from plant cellulose marks “important step” toward sustainable materials

A paper published in Advanced Functional Materials demonstrates a method for creating, and 3D printing, inks made from plant cellulose. 3D printed grids made from the …

Embedded 3D Printing for Soft Robotics Fabrication

(Nanowerk) A research team led by professors Jennifer A. Lewis and Robert Wood from Harvard University, have demonstrated a new method for creating highly stretchable sensors based on embedded 3D printing of a carbon-based resistive ink within an elastomeric matrix (for which they coined the term ‘e-3DP’). To enable e-3DP, the team developed a multi-component materials system composed of an ink, reservoir and filler fluid. These constituents are tailored to exhibit the desired rheological properties required to maintain high-fidelity geometries throughout the embedded printing and curing process. While attention has focused on 3D printing of rigid materials such as plastics and metals, this work demonstrates the printing of soft materials, which opens up myriad applications – including soft robots, actuators and wearable sensors.

Microscale 3D Printing Technique Created by Harvard Professor

(HarvardSEAS) A sophisticated microscale 3D printing technique developed by Jennifer A. Lewis, Hansjorg Wyss Professor of Biologically Inspired Engineering at the Harvard School of Engineering and Applied Sciences was on this year’s Technology Review‘s annual list of 10 Breakthrough Technologies. Those on the list “mark true milestones” and “solve thorny problems or create powerful new ways of using technology.” Lewis’s lab was praised for the range of materials and types of objects it can print. Lewis and her students showed they could print the microscopic electrodes and other components needed for tiny lithium-ion batteries.

Harvard Professor’s Step Toward the Bioprinting of Living Tissues

(Harvard) A new bioprinting method developed at the Wyss Institute for Biologically Inspired Engineering at The Harvard School of Engineering and Applied Sciences creates intricately patterned 3D tissue constructs with multiple types of cells and tiny blood vessels. The work represents a major step toward a longstanding goal of tissue engineers: creating human tissue constructs realistic enough to test drug safety and effectiveness. The method also represents an early but important step toward building fully functional replacements for injured or diseased tissue that can be designed from CAT scan data using computer-aided design, printed in 3D at the push of a button and used by surgeons to repair or replace damaged tissue.
