Wood-based 3D printing: Potential and limitation to 3D print building elements with cellulose & lignin

Under urgent sustainability targets, the building industry craves for renewable and recyclable biomaterials as cellulose is a fiber; Lignin is a plant-derived low-cost polymer with remarkable properties, yet its valorization is in its infancy. Recent studies have shown potentials to combine cellulose and lignin into a renewable bio-based...

Multi-material additive manufacturing in architecture and construction: A review

Multi-Material Additive Manufacturing (MMAM) is an emerging manufacturing approach that is gaining interest in architecture and construction as an expansion of Additive Manufacturing. Hereby, different materials or material properties are combined in a single additive process in order to create objects that are composed of multiple materials....

Re-printing architectural heritage: Exploring current 3D printing and scanning technologies

Additive Manufacturing (commonly known as 3D printing) technology has become a global phenomenon. In the domain of heritage, 3D printing is seen as a time and cost efficient method for restoring vulnerable architectural structures. The technology can also provide an opportunity to reproduce missing or destroyed cultural heritage, in the cases...

Development and prototyping of an integrated 3D-printed façade for thermal regulation in complex geometries

Currently, several research projects investigate Additive Manufacturing (AM) technology as possible construction method for future buildings. AM methods have some advantages over other production processes, such as great freedom of form, shape complexity, scale and material use. These characteristics are relevant for façade applications, which...
