法国轮胎制造商米其林has reached a new milestone in the development of its airless Uptis (Unique Puncture-proof Tire System) tire, having carried out successful road tests.
As part of Michelin’s VISION concept, if Uptis goes to market in 2024 as planned, drivers would be able to 3D print the tread and adapt the tires according to their driving, seasonal weather conditions, and to self-maintain the general health of the tire.
3D打印已经被用来创建轮胎的原型，但是有关涉及的添加剂制造技术以及将来它们将在未来使用的程度的进一步详细信息仍有待观察。
无空，可生物降解的概念
米其林首先提出了UPTIS概念轮胎at its International Mobility Summit,Movin’on, in 2017. The tire was designed to be airless in order to eliminate punctures while being biodegradable and equipped with sensors for real-time monitoring.
轮胎的无气内部设计基于肺泡结构，例如在肺中发现的肺泡结构，该结构具有适用于3D打印的复杂内部几何形状。为了创建该节目的原型，米其林与汽车制造商合作通用汽车to 3D print the concept tire.
Ultimately, Michelin is seeking to reduce the number of tires thrown away due to punctures, which, according to an in-house “scrapyard survey”,大约有200万吨，或埃菲尔铁塔的重量200倍。该公司认为，由于其无空的性质和“可充电”的潜力，其Uptis Tire可以完全避免这种浪费。
从增材制造的角度来看，轮胎的“可充电”概念是设计中最有趣的元素，并且可以看到驾驶员在路边重印其轮胎胎面。
Uptis的可充电胎面
Through its VISION concept, Michelin is aiming to make mobility safer, cleaner, more efficient, and universally accessible. The concept demonstrates how the company’s sustainable development model hopes to transform tire manufacturing between now and 2050, the date by which the欧盟的目标是气候中立。
视力的四个支柱是无空气，可充电，连接和100％可持续的。为了实现其无空目标，米其林正在开发技术，以消除公寓的风险和快速的压力损失以提高安全性和舒适性，同时减少轮胎浪费的环境影响。
这Connected element of VISION sees the Uptis equipped with numerous sensors to usher in a “new era” of service, comfort, and safety for motorists, while its Sustainable pillar sees Uptis manufactured by biosourced and recycled materials in order to ensure the environmental footprint of the tire’s lifecycle is minimal.
最后，被米其林称为其视野概念的“最革命性”方面之一，是可充电的承诺。根据该公司的说法，拥有3D打印胎面的轮胎使得可以将适量的橡胶化合物存放，从而减少原材料的使用。
随后，可以使用3D打印机“充电”轮胎，该打印机根据驾驶者的需求重印轮胎胎面。例如，驾驶员可能想适应轮胎适应冬季或夏季的状况，或者只是由于磨损而保留轮胎的总体健康状况。
With 3D printing, Michelin says these adjustments could be made quickly and easily via an on-demand service that could see drivers 3D print new treads for their tires by the roadside. While further details are still to come regarding which 3D printing technologies would be used, and in what capacity, it seems 3D printed roadside repairs could become reality when the tire comes to the market in 2024.
米其林already uses metal 3D printing to design and create multiple products, including thecomponents of tire molds。展望未来，该公司将进一步利用这种专业知识来探索橡胶3D打印，以提供其用于轮胎胎面的充电概念。
Test driving the Uptis
这latest development in Michelin’s VISION has seen the Uptis transfer from concept to the road. Automotive YouTubers Mr. JWW and Gercollector were brought in to test the prototype Uptis in real-life conditions on public roads.
米其林集团技术和科学传播总监Cyrille Roget说：“我们最大的满足感是在示威结束时，当我们的乘客说与传统轮胎没有差异时，我们两人都为轮胎表示了极大的赞誉。”
