Stronger, lighter 3D-printed plastics with impressive strength and energy absorption abilities

"studied: fused filament 3D printing using polyetherimide across 4 different lattice designs built at 3 different relative wall thicknesses... surprisingly, energy absorption attribute worst when >2 plastic strand layers laid next to each other... best-performing lattices had cell walls no more than twice as thick as that of polyetherimide strand... more crash-resistant cars, where plastic lattice helps absorb impact, aerospace design, where lightness could enable more fuel-efficient aircraft"
