普象-让好设计发光

What would a perfect hiking backpack system look like if it were to reduce the unpleasant sensations of warmth and friction? The team set out to redesign conventional backpack padding and put the first 3D-printed padding to the test. A fully integrated cushioning experience unlocks superior comfort thanks to freely designable lattice structures made possible only by Additive Manufacturing.

The open cell structure of the 3D-printed paddings greatly improves air ventilation, reduces heat accumulation, and thus significantly reduces temperature and relative humidity at the contact area with the back. The special Ultrasint® TPU01 material is a multi-purpose TPU that provides strong, flexible and ultra-durable part performance while maintaining excellent surface quality. In addition, the material is very easy to print, with high process stability and one of the highest throughputs for flexible material in the 3D-printing market.

Thanks to the design flexibility enabled by 3D-printing, the back pads and hip fins can be produced in a single piece out of one material. This significantly reduces assembly steps, time and cost. The printed part no longer requires gluing or sewing. Moreover, unprocessed powder gets fully reused in subsequent print jobs and printed parts are 100% recyclable at the end of their lifecycles.

Customised solutions are also available for printing backpack elements, including a full range of services from development to global production. In addition to comfort and performance, the backpack offers limitless design flexibility, simple and quick assembly, TPU that is fully recyclable and printed backpack elements that are completely sustainable.

远足背包的设计是为了在携带重物的同时保持舒适和时尚。设计团队着手重塑传统的背包衬垫，3D打印衬垫取代了传统的基于泡沫的背包垫，开孔结构极大地改善了空气通风，减少热量积累，从而大大降低了与背部接触区域的温度和相对湿度，为户外爱好者提供了其所需的舒适性。

此外，该背包还提供了自由的设计灵活性、简单快速的装配、可完全回收的TPU，以及完全可持续发展的印刷背包元件。特殊的Ultrasint TPU01材料是一种多用途的TPU，在保持优异的表面质量的同时，提供了强大的、灵活的和超耐用的零件性能。这种材料非常容易打印，具有很高的工艺稳定性，以及3D打印市场上柔性材料的最高吞吐量。

由于3D打印技术带来的设计灵活性，背垫和臀部鳍片可以用一种材料单件生产，大大减少了装配步骤、时间和成本，打印出来的部件不再需要胶合或缝合。此外，未加工的粉末可以在后续的打印工作中完全重复使用，打印的部件在其生命周期结束后可以100%回收。
