• The focus of the present work was the investigation of dimensional stability in 3D printing with mycelium-based materials. This material composite is made of wood fibers that are bound by mycelium growth. Hemp and coconut fibers were examined as materials for 3D-printing in order to evaluate their suitability for this purpose. In order for the material to be used for 3D-printing, binders and waterThe focus of the present work was the investigation of dimensional stability in 3D printing with mycelium-based materials. This material composite is made of wood fibers that are bound by mycelium growth. Hemp and coconut fibers were examined as materials for 3D-printing in order to evaluate their suitability for this purpose. In order for the material to be used for 3D-printing, binders and water must be added to make the ink extrudable. Different compositions of the printing paste were produced and the loss of shape after 3D-printing and after heat inactivation was compared. The results of the study showed that, compared to hemp fibers, coconut fibers effectively regulate moisture during cultivation. However, increased shrinkage was observed during heat inactivation due to the higher water content.…
