Since our original post about Within Technologies the use of their software which models 3D Printable objects in ways that mimic nature (complex internal and external optimized structures) has expanded.
In this video, EOS explain how they are working with Within Technologies to 3D Print parts with extreme degrees of structural complexity. Here, a heat ex-changer is shown designed for Formula 1 racing cars. The strength/weight ratio is significantly increased.
A hip 'cup' for human implant is also shown. It was grown in titanium by the Within Medical team. It's structure includes zones of randomized porosity. This allows for bone and tissue growth into the artificial joint.
Such geometries are impossible to achieve using any other manufacturing process.
Within Technologies is a UK engineering consultancy and software development firm who have dramatically advanced 3D design software in ways that enable the modelling of latticed micro-structures and variable density surface skins combined with "Bio-inspired" shapes.
At the core of the software lies an optimization engine which takes input parameters such as desired weight requirements, maximum displacement and stiffness. It is then able to create an optimized component design with a variable density lattice structure and surface skin which meets your exact specification. The optimized component can then be manufactured using one of many additive manufacturing machines (plastics or metals) to create products.
