Chow from a 3-D printer? Natick researchers are working on it
"We have a three-year shelf-life requirement for the MRE," Oleksyk said. "We're interested in maybe printing food that is tailored to a Soldier's nutritional needs and then applying another novel process to render it shelf stable, if needed."
Oleksyk said they are looking at ultrasonic agglomeration, which produces compact, small snack-type items. Combining 3-D printing with this process could yield a nutrient-dense, shelf-stable product.
