Columbia University Creates 3D-Printed Timber Lookalike with Internal Grain Pattern
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 techniques. While conveying the external profile and patterns of natural objects is tried and tested, a major challenge in the 3D printing industry has been replicating an object?s internal texture.

While conveying the external profile and patterns of natural objects is tried and tested, a major challenge in the 3D printing industry has been replicating an object?s internal texture.In their recent study ?Digital Wood: 3D Internal Color Texture Mapping? the research team describes how a system of ?color and voxel mapping ?led to the production of a 3D printed closely resembling the texture of olive wood, including a cut-through section.

To scan the original wood specimen, researchers used a destructive imaging technique where the wood was sliced at intervals of 27 micrometers (.027mm) on a computer numerical control (CNC) mill. The resulting set of 230 stacked images was prepared for manufacturing using a 3D printable code and a polyjet printer supplied by research partners Stratasys.
