3D-printed padding for outdoor backpack series
Lattice structure sets new standards in comfort, weight reduction & ventilation
Description of the component:
The new "3D Aerorise 40" model and the entire "Aerorise" backpack series from German outdoor market leader Jack Wolfskin will in future be equipped with 3D-printed back pads from OECHSLER. These will be produced with the help of Carbon's "Idea-to-Production" platform. The pads are optimized for the adjacent body zones and offer outdoor enthusiasts the comfort they need.
The challenge:
Every outdoor enthusiast knows the problem. After long hikes, heat, moisture and pressure points develop where the T-shirt and rucksack meet. To increase ventilation and improve comfort in the shoulder and lumbar area, Jack Wolfskin's new "Aerorise" series uses additively manufactured back pads from OECHSLER.
A more open grid structure (called "Lattice"), which can only be produced using the 3D printing process, increases air circulation in the carrying area compared to conventional foam padding.
Solution:
Together with OECHSLER and Carbon, four corresponding pads were developed, which are used as a comfort element in the brand new "3D Aerorise 40" model. Thanks to its open geometry, Lattice not only reduces the overall weight of the padding, but also the temperature in stress zones by up to five degrees Celsius thanks to improved ventilation.
Another advantage is that the grid, consisting of thousands of rod-shaped, elastic connections with different vertical and horizontal strengths, can be individually adapted to each application. The hardness levels of the backpack pads have thus been optimized with regard to the adjacent body structures: Soft where comfort is crucial and firmer where stability is required. This increases comfort, especially under high loads.
Conclusion:
Additive manufacturing is one of the fastest-growing production technologies that has already impressed and innovated many industries thanks to its flexibility. Almost any upholstery can be replaced by a grid structure. OECHSLER has already confirmed this with the series production of American football helmets, bicycle saddles and car seats.
