Three dimensional fiber deposition (3DFD) is a solid free forming technique for the manufacture of complex metallic and ceramic parts with controlled porosity, pore size and specific architectures.It is used for a wide range of applications, e.g.the construction of bone scaffolds, active ceramic composites, photonics.The technique is also ideally suited for structured catalyst manufacture, as it allows to determine and design the catalytic reactor internal, with a perfect control of the flow behaviour inside of the reactor.Periodic and highly reproducible support structures, with good mechanical properties and low pressure drop can be manufactured through the use of 3DFD [1,2].These support structures can then be coated with a catalyst.
