Infra; Pedal

The Infra pedal shows the power of algorithmic design for the generation of internal structures for product design. By varying the density of the structure of the pedal, the textured top and bottom solid surface blend smoothly into the lightweight porous mid-section. With algorithmic control over each point of the 3d model it becomes possible to blur the boundary between structure and surface in an organic and controllable way.

Although there is a benefit in making products lighter whilst retaining structural properties, abnormal focuses on integrating the engineering requirements with design decisions. Through our process, design and engineering are fully integrated and receptive to creative / art direction. Products are much more than their functional requirements. In our algorithms affordances and other qualities directly interact and inform structural requirements enabling a hybrid of design and engineering that pushes the boundaries of what is possible.

Algorithmically generating the internal structure also enables us to design for manufacturing. This becomes especially relevant when executing a design like the Infra Pedal through additive manufacturing processes. The angle of each beam can, for example, be adjusted to make the pedal manufacturable without support on a variety of printers. The current version of the Infra Pedal is printed in laser-sintered nylon.

The capacity to design for manufacturing becomes even more apparent when it comes to mould making. Adding air channels and interlocking mould segments can all be done algorithmically enabling highly complex forms to be cast from many more materials.
