从吉米·亨德里克斯（Jimi Hendrix）到库尔特·科本（Kurt Cobain） - 吉他粉碎是许多摇滚传奇人物分享的标志性动作。但是，这与添加剂制造有什么关系？在一个不寻常的案例研究中，瑞典工程小组Sandvik已经确定了这些破坏性的摇滚时刻，是展示其先进生产技术的机会。结果，该公司生产了“世界上第一款防撞3D印刷吉他”。
Featuring a 3D printed titanium body, and a neck supported by Sandvik’s hyper-duplex steel technology, this instrument has a super strength proven to have rock-legends beaten.Putting it to the test, Sandvik challenged acclaimed guitar player and smasherYngwie Malmsteen打破它（扰流板警报：即使以下这些卑鄙的技能，他也做不到）。
Indestructible guitar? No fret
Malmsteen, a heavy metal veteran and named as one of the greatest electric guitar players in the world byTIME magazine, has been smashing guitars onstage for over 30 years. In a video from Sandvik however, it appears he has finally met his match. Following a live performance, playing the guitar, Malmsteen was unable to leave even a dent in its case.“This guitar is a beast! Sandvik is obviously on top of their game. They put the work in, they do their hours, I can relate to that,” Malmsteen commented.
“The result is amazing. I gave everything I had, but it was impossible to smash.”
Sandvik employed the skills of renowned guitar designer Andy Holt, of德鲁曼吉他, to help design the instrument. Before building the guitar, Sandvik utilized the simulation processes that car makers use to digitally crash-test vehicles. This was done to determine potential impact forces for the guitar, in order to ensure the durability of the instrument.
A complex manufacturing challenge
The body of the guitar was additively manufactured with titanium powder using aDirect Metal Laser Sintering(DMLS) machine. This provided the body with a mechanically strong and complex structure, featuring microscopically thin layers of titanium powder fused together using lasers. The volume knobs and tailpiece of the guitar were also created using 3D printing. Sandvik’s metalworking divisionSandvik Coromanttook charge of manufacturing the neck and fretboard of the guitar, machining it from a single solid block of stainless steel.
Sandvik的增材制造工程师Amelie Norrby说：“增材制造业使我们能够在小型生产运行中构建高度复杂的设计。”
“It lets us create lighter, stronger and more flexible components with internal structures that would be impossible to mill traditionally. And it is more sustainable because you only use the material you need for the component, minimizing waste.”
桑德维克（Sandvik）的工程师确定了吉他的一部分，脖子将身体连接在一起是该团队必须克服的仪器的主要弱点，以便将其植入坚不可摧的特性。为了解决这个问题，Sandvik将脖子和身体铣削在一起，作为一块统一的作品。为了进一步加强这一点，Sandvik还使用了放置在脖子和指板之间的晶格支撑结构。该结构由Sandvik的“超双链”钢制成，该钢具有高水平的腐蚀耐药性和机械强度。根据该公司的说法，晶格部分是给定重量的世界上最强的结构。
克拉斯·福斯斯特斯, President of Sandvik Machining Solutions, stated, “We don’t make products for consumers, so people don’t realize how far in the forefront our methods are.”
“Creating a smash-proof guitar for a demanding musician like Malmsteen highlights the capabilities we bring to all complex manufacturing challenges.”
Sandvik的重金属添加剂投资
近年来，桑德维克（Sandvik）在其增材制造能力上进行了大量投资。2018年，该公司分配了$25 million在瑞典建立专业的添加剂金属生产厂。
Later in the same year, the company also inked a partnership with UK 3D printer OEM雷尼沙toexpand its additive manufacturingcapabilities.
