基于新西兰的3D金属印刷服务提供商RAM3D最近与Somerset定制自行车生产商合作Sturdy Cycles到3D打印钛合金组件的公路自行车。
Having previouslyworked with bicycle brands in the past，Ram3D的3D打印专业知识由坚固的周期老板Tom Sturdy召集，为他的三种公路自行车型号生产零件，以创建无法使用传统方法制造的设计和结构。该公司还为他的定制自行车就新设计提供了建议，并让他参与了3D打印过程。
Sturdy希望在2021年推出一辆计时赛专家自行车，以与他现有的3D印刷型号并排排队，并可能考虑在将来的3D打印中设计和生产定制的电子自行车。
Sturdy and RAM3D’s partnership
Sturdy’s design process begins with a bike fitting to ensure the bike will be fully customized to that specific customer, from which data is used to develop both the geometry and structural design of the bike. RAM3D then deploys its 3D printing technology, using an SLM Solutions 280HL 3D printer, to produce the bike frame and some components.
除了优化零件的延展性，可加工性以及尺寸和结构稳定性外，RAM3D的所有钛3D印刷零件都进行了热处理，以减少制造过程中产生的残余应力。
根据Sturdy的说法，添加剂制造允许传统雷电竞充值技术无法生产框架的几何形状和结构。能够通过3D打印来利用钛的强大力量和节省重量的好处一直是Gamechanger。
“There is the purist element with titanium, it doesn’t need to be painted or finished and for a lot of people, that is quite a big appeal,” he said. The increased customization made possible by RAM3D’s 3D printing technology is now an integral part of Sturdy’s bespoke bike frame business.
RAM3D在其总部还设有7台Renishaw AM250 SLM机器，运行15-5ph不锈钢，不锈钢316L，Inconel 718和Aluminum Alsi10mg。
3D printing in the bike sector
自行车行业长期以来拥护马添加剂nufacturing technologies, with several manufacturers opting for 3D printing technologies over traditional methods for the production of bike frames and components. With its excellent strength to weight ratio, titanium is a desirable manufacturing material for bicycles, and is being increasingly employed hand in hand with 3D printing within the cycle sector.
Earlier this year, global engineering group桑德维克announced a collaboration with e-bike engineering and design consultancy GSD Global to3D print titanium motor nodes用于几家原始设备制造商（OEM）的电子自行车。在其他地方，澳大利亚自行车制造商Bastion Cyclespurchased anAM250 3D printer来自英国的添加剂制造专家雷电竞充值Renishaw，为了带来以前的外源内部3D打印操作。
More recently, a modern titanium mountain bike from胡恩周期, which offers the same lightness and stiffness as those manufactured from carbon,took first placein this year’s FormnextPurmundus Challenge。Titanium offers sustainability benefits over carbon fiber frames as they can be recycled over and over again. But despite its短生命周期，许多制造商仍然热衷于探索碳的3D打印自行车框架和组件的潜力。
One of these includes Silicon Valley firmarevo正在与新的加利福尼亚的初创企业合作Superstrata到3D打印fully-unified carbon composite frames因为它即将到来的电子自行车。该框架是使用Arevo的连续碳纤维3D打印技术在单个零件中生产的，从而消除了对胶合或焊接组件将组件固定在一起的需求。碳3D打印零件也已使用Urwahn自行车’Schmolke Edition自行车, developed at lightweight bike component specialistSchmolke Carbon。
