Purpose and goal
The overall goal of the project has been achieved. Materials and function specifications for the demonstrators (building elements and details for truck interiors) have been developed. The material combinations have been developed to be compatible with the chosen additive manufacturing method (AM). The digital design and information systems are ready for large-scale AM. Demonstrators are produced from the wood fiber-based composites developed. A technology for spatial printing with continuous fibre has been developed. A Stage3 application will be prepared.
Expected results and effects
Wouldwood aims to create an integrated industrial design, materials and production value chain for advanced additive manufacturing of wood-based components for the construction and transport industries. Wouldwood2 developed a material concept with 50 percent wood fibre in a bio-based binder together with a complete digital chain from design to additive manufacturing of large-scale components. LCA shows that the solution can be part of the bio-based circular economy. A technology for real spatial 3D printing has been developed and offers new possibilities.
Planned approach and implementation
The partner organizations contributed to the production of the demonstrators. Technology concepts were verified on both lab scale and pilot scale. Four demonstrators were produced. Developed workflows and codes for the software were tested in the development of the demonstrators. The material development of wood fibre reinforced polypropene was done in several iterative steps and four material combinations were developed. Mechanical testing of the printed elements, evaluation via the developed evaluation protocol and fire tests showed the potential of Wouldwood.
