Innovation in 3D printing - Fraunhofer IGD develops new process for the avoidance of stair-step artifacts
Scientists at Fraunhofer IGD have devised a purely geometric and algorithmic method for the elimination of stair-step artifacts in multi-material 3D printing. To avoid quantization errors, the surface of the object is modulated with a high-frequency signal. This results in geometrically accurate and color-true surfaces. The research team have set down their findings in a paper – Shape Dithering for 3D Printing – which will be published to coincide with SIGGRAPH, the premier conference and exhibition on computer graphics and interactive techniques.
