Addwood – 3D Printing Wooden Furniture

Material-efficient and sustainable furniture production using residues from the wood industry 

Objective

The aim of the Addwood project is to ensure the most material and resource-friendly possible manufacture of complex workpieces using the renewable resource wood. In order to accomplish this, an additive manufacturing process for wood, also known as 3D printing, is currently being developed; it will not only use the resource wood more efficiently, but also set new design standards in furniture production.

Tasks

  • Material development: the development of a new, additively processable wood material, based on residues from the woodworking industry, which have previously only been used to a limited extent
  • Process development: transfer of the process to a pilot scale
  • Production of prototypes: manufacture of furniture and assessment of its marketability

Status Quo

The manufacture of wooden products traditionally uses subtractive processes in which components are cut or milled from a piece of wood. These processes result in wood residues and chips. Additive processes, on the other hand, build components from materials layer by layer. The fact that the used wood material remains completely within the finished workpiece or is available for the production of the next workpiece means that the additive process is characterized by better material efficiency.

The additive manufacturing of products has made major progress in recent years and is already being used in many branches of industry. However, it is mainly plastics that are used as the material for printing products and natural materials have so far hardly been used. The additive manufacturing of wooden products has also not yet been able to establish itself as there is no marketable material and process available.

Advantages

The additive manufacturing process is a future-oriented process that can fundamentally change the industry for manufacturing wooden products and thus open up new areas of business. It also has great potential when it comes to making production more sustainable: On the one hand, wooden products can be manufactured without any waste and, on the other hand, residual material from carpentry workshops in the form of chippings, which have so far essentially only been used to generate energy, can be used as the base material. Another advantage is that additive manufacturing allows for complex shapes to be produced. Free forming offer architects more design freedom, not only in the manufacture of furniture, but also for building components in the future.
