Scientist develop ingestible 3D-printed snake-like robot

Scientists have developed a tiny, ingestible 3D-printed snake-like robot called SAW (single actuator wave-like robot), that can navigate through the small intestines.

The snake-like tiny robot was made from a set of interlocking 3D-printed “plastic” pieces that look like vertebrae.

Key Facts
  • The robot moves in a wave-like motion and can travel through the extremely squishy environment of the small intestine.
  • The external shape of the robot is a 2D projection of a rotating helix, that result in a continuously moving wave. Its direction can be reversed simply by reversing the direction of rotation of the motor.
  • In tests, the robot was able to move incredibly fast and cross a wide array of terrains, from water to rough, rocky soil.
  • Potential application: It can be used to visualise the digestive system in real time, especially for colonoscopies.

Scientists develop artificial human lung model using 3D printing

Scientists from Czech Republic have developed a model of a functioning human lung using 3D printing and other technologies. It has received three patents for its modeling.

The model was developed by the research group from the Brno University of Technology. It can be used to simulate problems like asthma or other chronic diseases and their treatments.

Key Facts

  • It is mechanical- and computer-based model of the lung developed by utilizing an array of modern technologies including 3D printing.
  • It can help devise treatment methods with more precision than past testing and tailor it to individual patients.
  • It can also be used as a reference model for developing inhaled drugs. It can show whether an inhaled drug will settle in the concrete areas where we need it to.

Scientists develop new bio-ink for 3D bio-printing with stem cells

Scientists have developed a new stem cell-containing bio-ink that allows 3D printing of complex living tissues that may be used for surgical implants.

The medical breakthrough was achieved by scientists from the University of Bristol, England. The study in this regard was published in the journal Advanced Healthcare Materials.

Key Facts

  • The new bio ink containing stem cells allows scientists to 3D print of living tissue which is also known as bio-printing.
  • The ink contains two different polymer components: a natural polymer and a sacrificial synthetic polymer.
  • The natural polymer was extracted from seaweed. It provides structural support when the cell nutrients are introduced.
  • The synthetic polymer used in the medical industry helps the bio-ink to change its state from liquid to solid when the temperature is raised.
  • The special bio-ink formulation has helped scientists to construct complex living 3D architectures after it was extruded from a retrofitted benchtop 3D printer, as a liquid that later transformed to a gel at 37°C.

What is stem cell?

  • Stem cell is an undifferentiated cell of a multicellular organism which is capable of giving rise to indefinitely more cells (through mitosis) of the same type and from which certain other kinds of cell may be formed by the cellular differentiation.
  • In the stem cell treatments new adult cells are introduced into the damaged tissue through the intervention strategy to treat the disease.
  • These treatments have potential to change the face of curing human diseases and alleviate suffering.
