THE CHALLENGE
3D printing has transformed industries by enabling the use of Additive Manufacturing (AM) techniques. Unfortunately, most 3D printing is done by sequentially printing two dimensional layers; this means that classic 3D printers are unable to fabricate parts with complex load paths. The weaknesses introduced at layer interfaces significantly limit the application of 3D printed parts in multiple industries that could benefit.
OUR SOLUTION
Drs. Williams and Kubalak have designed a generalized algorithm for generating multi-axis toolpaths to fabricate layer-less (unconstrained) 3D objects. While existing multi-axis material extrusion techniques are restricted to planar or curved surfaces, this algorithm uses multi axis deposition to freely align material to 3D non planar load paths. This process adds strength and added complexity to the structures fabricated using AM.
