Cellulose and Lignin in Additive Manufacturing: Potential and challenges in the fabrication of structural nodes for free-form building envelope structures

The building stock and the construction industry combined are responsible for a large share of greenhouse gases emissions. At the same time, every year tons of wood, paper and agricultural residues are wasted instead of recycled and upcycled into the production chain. In the fabrication field, the relevance of additive manufacturing processes is...

Wood-based 3D printing: Potential & limitation to 3D print a window frame with pure cellulose & lignin

With a building industry that is responsible for a large amount of our carbon emissions, a rising population, and the over-extraction of resources, architects and engineers have the responsibility to use environmentally friendly products. Lignin and cellulose are the most abundant biopolymers on earth and produce a lot of waste by ending up...

3D printed fiber reinforced lignin: Exploring the options to use wood in an additive manufacturing process

Problem definition and objective - Additive manufacturing has already been developed to use various sorts of plastics, metals, composites and concrete. Until now, the most used composite in building materials, natural wood, has not been used in an additive manufacturing process. The potential of using wood in<br/>an additive manufacturing...
