Pennsylvania-based car restoration shop哈恩自动恢复正在利用3D扫描为其客户之一构建定制的菲亚尔猫汽车。
The client came to the company with the desire to build a new car, and the partners embarked upon creating the Fiat-Hellcat after being inspired by the Fiat Topolino drag racers of the 1950s and ‘60s, where drag racers would attach a Topolino body to their Rail Dragsters.
To create the Hot Rod, the company used 3D scanning to fit a Fiat 500 body to a Dodge Charger Hellcat chassis and determine where to precisely cut the cars in order to join them together.
Hahn Auto Restoration的创始人兼所有者William Hahn说：“菲亚特·赫尔猫（Fiat-Hellcat）的项目最初是因为大多数热棒，两个成年的成年人无人看管，通常会梦想着做事的事情，或者不那么好。”“但是，我们希望能够在街上驾驶它，在赛道上赛跑，自动摩擦，所有这些设施都采用空调和音频系统等现代设施。”
Leveraging AM for car restoration
Hahn has been restoring cars for close to 50 years, and established Hahn Auto Restoration in 2001 with Wes Woodward, originally under the name Hahn and Woodward. After Woodward sold his shares, Paul Vorbach came on board as a junior partner and the business was renamed to Hahn-Vorbach.
Hahn-Vorbach, as it was then known, became nationally recognized for its car restorations and custom builds, having displayed its work at some of the finest Concours shows in the US, such as Pebble Beach, Amelia Island, and The Elegance at Hershey.
Soon after, Hahn and Vorbach started a spin-off company,HV3D，它试图利用3D打印来帮助解决定位稀有且昂贵的组件以制造汽车的挑战。在2017年，两人决定全力以赴。Hahn保留了恢复公司，该公司成为Hahn Auto Restoration，Vorbach拥有HV3DWorks的全部所有权。
The two have remained close friends and business partners, referring custom to each other as appropriate. Hahn has also continued to leverage 3D printing and scanning technologies to complete his restorations and custom car builds.
“I think our first foray was to produce a 300SL emblem for a 1956 Mercedes-Benz Gullwing,” he said. “Some clients wanted custom emblems for their cars. In those cases, we were also able to produce down-sized versions of their custom emblem which they could install on their dashboard.
“最近我们生产1957奥斯汀的象征Healey. The original engine was a 6-cylinder and so it had an emblem with a ‘6’ as part of the emblem. The car now has a Corvette V-8 engine, so we changed the ‘6’ to an ‘8’ while keeping the same style and font.”
3D打印和扫描的好处
Hahn Auto Restoration利用3D打印主要是在不锈钢中生产最终用途的零件，这些钢往往需要进行后处理工作，例如打磨或归档，然后将其发送给抛光和镀铬。该公司已经利用3D打印和扫描已有六年了，并与充电器金属工程的杰里·马丁（Jerry Martin）合作，通过试用和错误找到用于打印的最佳金属。
According to Hahn, one of the most significant benefits of using 3D printing is the high cost savings, “otherwise many parts just couldn’t be justified.” He also acknowledges the technology makes it easy to downscale or upscale the size of a client’s design, as the firm demonstrated with their 3D printed emblems.
Aside from 3D printing parts, the company deploys 3D scanning for a variety of other reasons. For instance, scanning a part enables the shop to have a copy saved and able to be reproduced should it be destroyed during a vintage race.
Additionally, 3D scanning enables the shop to compare a wrecked car, or a vehicle that has experienced “less than perfect” repairs, to determine any defects.
哈恩说：“在恢复了梅赛德斯·奔驰300SL的鸥翼屋和Roadsters的尸体之后，我们的尸体在工厂绘画的几毫米范围内，我们3D扫描了每张图纸。”“现在，我们可以扫描新客户的300辆汽车，覆盖扫描，并确切确定面板的损坏。因此，没有留下窍门的空间。”
Building the Fiat-Hellcat
3D扫描还允许商店在切开汽车时找到最好的线路，以便通过商店的菲亚特 - 赫尔猫项目“将其结婚”到另一个身体或底盘。
“I located a Dodge Charger Hellcat that was rolled over and totaled by the insurance company,” said Hahn. “It had less than 3,000 miles and out of Texas. Then, we bought a high mileage but rust-free Fiat 500. We reinforced the chassis portion of the Charger, then cut the body off while leaving plenty left over. We then removed the driveline from the Fiat and reinforced the body.”
Once this stage had been completed, Hahn brought in the services of Chris Tomko, a former employee who founded ‘AMClad’ tooling manufacturerFreshmade 3Dwhich wasbought by binder jet 3D printer manufacturer ExOneearlier this year.
Tomko scanned both the Dodge and Fiat then overlaid the scans to determine precisely where Hahn would need to cut the cars in order to join them together. The Fiat-Hellcat was then married together with new panels fabricated from 4130 high-strength steel and welded together. Hahn and Tomko are now discussing potentially 3D printing new body panels for custom cars.
Restoring classic cars
3D打印和扫描技术之前已经利用了用于逆向工程和制造经典汽车的稀有或停产零件。
For instance, British restoration teamRedesign Sporthas previously deployed 3D scanning and CAD modeling toreverse engineer a classic Ferrari, while保时捷和Mercedes-Benz两者兼而有之leveraged 3D printingtomanufacture spare partsfor their classic models.
Meanwhile, in June,索伯工程announced plans to establish a 3D printing business to produce按需经典汽车备件to meet the demands of vintage automobile enthusiasts.
Recreating rare classic car parts using3D printing and scanning has even made it onto TV当流行的英国汽车电视节目时Car SOS部署了技术来恢复1970年代福特Cortina Mark III X的定制中央控制台。
