Professors 3D print first truly microfluidic “lab on a chip” device

  • Researchers at Brigham Young University have 3D printed a first of its kind viable microfluidic device small enough to be effective at a scale much less than 100 micrometers.
  • Greg Nordin, a BYU electrical engineering professor said the advantages of 3D printing for microfluidic device fabrication are already well-known and that their method, digital light processing stereolithography (DLP-SLA), is an especially promising lower-cost approach.

KNTU researchers make 3D printed decoder for the brain

  • The laboratory of Integrated Circuits and Systems (ICAS) at Khajeh Nasar Toosi University of Technology of Iran (KNTU) has developed a 3D printed device capable of recording activity in the brain.
  • When implanted, electrocorticography systems like the one from KNTU can be tuned to become a part of the brain itself. As a brain-machine interface (BMI) the devices can help restore damage to the senses and movement.

3D printing accident leads to ‘tissue paper’ with healing properties

  • A lab mishap led to what the Northwestern University team now refers to as “tissue paper” — thin, paperlike sheets that are made from a variety of organ and tissue types.
  • The ovarian tissue paper could potentially be implanted under the arm to restore normal hormone function to women with reduced fertility. Moreover, it could eventually be used to repair organs or muscles during surgery, or even as a bioactive Band-Aid that would facilitate the healing of a wound.

Defending 3D printers from hackers

  • Researchers at Rutgers University and the Georgia Institute of Technology have revealed a trio of techniques to monitor 3D printers from cyberattacks.
  • The researchers focused on three different ways to determine if a 3D printer was hacked.

IdiPAZ researchers work with MIT on 3D printed cornea replacements

  • The Instituto de Investigación Biomédica del Hospital La Paz (IdiPAZ) in Madrid, Spain, working toward the goal of 3D printing human corneas within the next five years.
  • In order to achieve their goal, the researchers propose a direct 3D printing method using native, autologous, stem cells to synthesize layers of collagen for transplant. The technique will likely require the development of a high-resolution 3D bioprinting process, that layers tissue cell by cell.

Cancer diseased spine replaced by 3D printed vertebrae at Shanghai Changzheng Hospital

  • In an operation believed to be the first of its kind in the world, surgeons at the Shanghai Changzheng Hospital have replaced a portion of a woman’s spine with metal 3D printed vertebrae.
  • Using the 3D printed plastic model as a frame, the team of chief physician Dr. Xiao Jianru designed a new implant to replace the six diseased vertebrae of the patient. The implant was 3D printed in titanium.
