Application

  • Current manufacturing and processing of wood uses hazardous materials and traditional low-tech methods.  The existing methods require significant manpower, but more importantly, limits the versatility and personalization of the products.
  • Hazardous materials that are currently used as binders such as formaldehyde are under regulatory pressure to be phased out. Current “look-alike” digital wood products are simple plastics which do not obtain warmth and tactility properties
  • Furthermore, the amount of unused wood residues from industrial processes increases yearly without any viable market.
  • There is a need for materials and printing technologies for fabrication of whole wood 3D printed objects that are biodegradable and free from chemicals.

Our Innovation

The research group developed a natural binder that enables digital printing of wood-coated plastics. The composition comprises of wood and other materials, for use in a process of encapsulating or coating or covering a surface region of a plastic or a polymeric material.  The resulting printed structure has superior mechanical properties over MDF and HDF, while retaining the feeling and sense of wood. Our offering is a digital wood printer and inks that form the hard base layer via a digital process for different geometries and topographies. Decorative and protective thin layers are inkjet printed as top coatings to give the final high-end look.

The Advantages 

  • 100% natural biodegradable materials
  • Complete design freedom for wooden products
  • Wood renewable - Ink inputs are considered “waste products” from other industrial processes.
  • Multiple wood typed in one print job
  • Tailoring the properties of the printed wood (thermal conductivity, acoustic, sense etc)
  • Compatible with existing hardware
