Microgravity environments improve the success of 3D bioprinting

Gravity can cause gaps, such as those in the chambers of a 3D-printed heart, to collapse before stem cells, hydrogels, and biochemicals bind together during the bioprinting process. Rather than Earth's surface, some bioprinting is done on the International Space Station, where defective organs are also printed to test treatment methods.

The benefits of 3D printing batteries, from safety to sustainability

Rather than using the liquid electrolyte commonly found in lithium-ion batteries, 3D-printed batteries would use a solid layer, which can be custom-built into different shapes, deliver higher energy density by building thinner layers, and be fabricated with fewer raw materials compared to injection molding.
