Systems and Materials Research Corporation (SMRC) 3D Printing Food for Space Missions

Image Posted on Updated on

According to the Systems and Materials Research Corporation (SMRC),” is developing technology for 3D printing food for space missions.  Astronauts typically do not get the type of food that we take for granted here on earth every day.  They get food in pouches that has very different flavor and texture compared to the food we eat daily on earth.  Also storing the food in the pouches for long term causes degradation in its nutrients.

SMRC is using 3D printing technology to provide astronauts in space with food similar to what we eat here on earth.  Also, their technology introduces nutrition supplements to compensate for any degradation due to long storage.  Also, if someone fell sick in space, their technology will be able to 3D print therapeutic food.

SMRC has demonstrated the technology by 3D printing pizza.  The 3D printer first dispenses pizza dough on a hot plate.  The dough is cooked and then pizza sauce and cheese is dispensed.  This technology could be critical if we had long term space missions in future, for example, a mission to Mars”.

Carnegie Mellon University 3D Prints Hair

Image Posted on Updated on

According to the Researchers and Carnegie Mellon University,” have developed a technique for 3D printing hair, fibers or bristles.  The researchers used a fused deposition modeling (FDM) printer.   The technique is similar forming thin strands by extruding glue from a hot glue thing and suddenly moving the hot glue away. Similarly, the technique extrudes molten plastic from the nozzle of the 3D printer and then moves the nozzle away rapidly.  The researchers call the technique fabrication.

3D printers typically can not move the nozzle up rapidly.  However, they can move the the nozzle sideways with respect to the print bed rapidly.  Therefore, instead of moving the nozzle up, the researchers moved the nozzle sideways.  The amount of molten plastic extruded and the speed with which the nozzle is moved away can be varied to control the thickness of hair generated.  These parameters are programmed into the 3D printer.

The technique presently creates hairs strands by strands. Therefore, the process is slow and takes 20-25 minutes to generate hair on 10 square mm2. Different types of material can be extruded from the 3D printer to create hair having different properties.The technique can be used to add hair to 3D printed objects, for example, hair on a head, whiskers, or hairy tails”.
