Mabe

The consumer goods industry is fast paced and highly competitive, with designs becoming increasingly complex while the timeline for production shrinks.

This project addresses the tedious and time consuming task of modeling the foam within the product door that helps maintain the internal temperature and also absorbs shock in a drop situation. Modeling the foam effectively is complex and difficult due to the complicated nature of the doors and other cavities, so the step was often skipped, causing inefficiencies with the product.

An Interview with Ben Farmer of Robot Bike Co. Discussing the Development of their R160 Bike with Altair

Robot Bike Company (RBC) is a new startup established in the UK by aerospace engineers and mountain biking enthusiasts who identified the potential of combining additive manufacturing technologies with carbon fiber to, in their own words, “create the best bike frames possible”. To deliver a customizable, lightweight, high strength bike, RBC’s frame was intended to be created from carbon fiber, a material very common in the industry. The carbon fiber tubes, as well as the bike’s other components and systems were to be joined by additively manufactured titanium ‘nodes’, manufactured based on the specification of individual riders. Altair ProductDesign’s engineering team was tasked with optimizing these joints, which included the head tube, seat post and chain stay lugs, to ensure they were as lightweight as possible and still able to withstand the forces of downhill mountain bike riding, all while being fit for the AM process.
