New Sources uses leftover materials from wood industry through an interconnection of 3d-scanning, computational design and robotic manufacturing. Raw birch branches are first 3D-scanned and then virtually processed by algorithms to constantly recalculate the production data for each individual part of an object. Due to the irregularity of the material every object becomes a unique piece, even if it is serially produced. The precisely milled surfaces and edges of the object stand in contrast to the raw branch texture and display the intersection between nature and technology. Birch bark partly remains and becomes a natural ornament to keep the original character of the material alive.
