3D Data Portal

Contact person for this topic is Dr. Tim Koddenberg.

Wood is a very heterogeneous material with a complex and three-dimensional (3D) structure at the microscopic level. With use of micro-computed tomography, this structural complexity of softwoods and hardwoods can be visualized non-destructively and three-dimensionally. The digital data enable new perspectives and approaches for research with and on wood due to the various visual and quantitative possibilities of examination which comes with this technique. Such data of wood benefit not only the wood research but also wood-based training professions and academic teaching. Using a 3D printer, digital 3D models (*.STL file format) can be printed enabling students, for instance, to experience the wood structure not only visually but also haptically. In addition to anatomical features of wood, the 3D models on this website also show selected research objects from other projects of the department of Wood Biology and Wood Products.

On this website, some examples of 3D models are available. To view and explore the models in 3D, press the "Play" button. You can easily manipulate the model (e.g., rotate, zoom) with your computer mouse. Many models provide descriptions/annotations and additional images (e.g., scanning electron microscopy images). These additions are intended to simplify the understanding/recognition of features in 3D. A click on the small numbers/annotations in the 3D models make additional information visible. You can also display the model in full screen by clicking the expanding arrow in right corner.

More 3D models and information are constantly added to this website.
