Researchers at New York’s Columbia University have unveiled a method of vibrantly replicating the external and internal structure of materials such as wood using a 3D printer and specialist scanning ...

Why it matters: Infill affects compressive strength, top surface quality, and material use. Overbuilding wastes filament without always improving durability. Pattern power: Patterns like gyroid, cubic ...

The technology continues to evolve, but 3D printing is still mostly used for creating prototypes or parts that won’t have to endure tremendous stresses or rigorous wear and tear. That might not always ...
