There seems to be no end to the advancements being made in 3D printing materials, and one type of material that has expanded and diversified recently has been 3D printed foam. Whether it's made from graphene or ceramic, 3D printed foam material imparts several desirable characteristics, such as strength, light weight, and insulating capabilities, that surpass those of other types of material. Those characteristics are especially attractive to those working in the aerospace industry, and 3D printed foam has drawn the attention of NASA, which recently offered $100,000 to West Virginia University to research the material. In addition, WVU received a three-year, $750,000 grant to develop ways to increase the onboard autonomy of planetary rovers.
