A 3D printing process that uses a wood-based ink to produce components with the unique ‘ultrastructure’ of wood has been demonstrated by a group of researchers from Sweden’s Chalmers University.  It is claimed that the technology could ultimately enable wood products to be “grown” to order.  The breakthrough builds on earlier research carried out by the team in which a 3D printing ink was produced by converting wood pulp into a nanocellulose gel.  By also interpreting and digitising wood’s genetic code the technique is able precisely control the arrangement of key ...
