molds and models in dimensions of up to 8 cu.m. But the British model builders were pursuing a different approach. To ensure that the Aston Martin was as true to detail as possible, and for the purpose of integrating numerous func- tions into the film models, they decided on an assembly consisting of 18 individual components. Te entire body is based on a steel frame, almost identical to how vehicles were assembled in the past.” voxeljet started the printing process once the CAD data
for all components were available. Te models are produced with the layer-wise application of particle material that is glued together with a binding agent. Te plastic material PMMA is used for this purpose. Te individual components made of PMMA feature outstanding attention to detail but are also stable and resilient, which means they are well suited for mechanical post-processing. Following the unpacking process, which involves the
removal of unbound material from the finished components, voxeljet’s service center looked very much like a body shop. Fifty-four individual parts for the three vehicle models, including mudguards, doors, bonnets, roofs and more, had to be safely packaged and transported to Pinewood Studios near London.
Te model builders at Propshop then meticulously as- sembled and finished the components, painted them in the original color and added chrome applications, along with realistic-looking bullet holes. After the finishing process, it is impossible to distinguish the Aston Martin models made with the voxeljet printer from the original, even in the close-up shots. And, the priceless Aston Martin DB5, which was used in the first James Bond film 50 years ago, remains unscathed, while one of the elaborately and meticulously constructed models explodes in flames in the film. “In addition to the automotive industry, foundries, designers and artists, the film industry represents an entirely new customer base for voxeljet,” Ederer said. “3D printing is on the cusp of a great future in the film industry. Te tech- nology offers fantastic opportunities, since it is usually much faster, more precise and more economical than classic model
construction.” Visit

以及成片模型集成众多功能的目的，他们决定由18独 立部件组成的总装。整个车身的基础为钢架，车辆的 组装与过去几乎是相同的。“
一旦所有组件的CAD数据完成，voxeljet开始打印 过程。模型的产生是把与粘合剂结合在一起的颗粒材 料逐层打印。使用的是塑料材料PMMA。 PMMA制 成的各个组成部分，具有出色的细节特征，但也是稳 定的，有弹性的，这意味着它们非常适合于机械后处 理。
随着出货的过程，从成品部件上除去多余的材
料，voxeljet的服务中心看起来非常像一个车身车 间。总共有54个独立部件将组装3个车模，其中包括 挡泥板，车门，机器盖，车顶等，需要安全地包装和 运输到伦敦附近的松林制片厂。 Propshop的模型组装工，在这精心完成组装，把 他们涂上原来的颜色，镀铬，以及逼真的弹孔。经过 后处理过程，即使在近距离拍摄也无法分辨阿斯顿• 马丁原型与voxeljet打印机打印的模型。然而，无价 的阿斯顿•马丁DB5，50年前已经第一次出现在詹姆 斯•邦德电影中，历经爆炸，火焰仍然毫发未损。 “除了汽车行业，铸造厂，设计师和艺术家，电影
界代表voxeljet公司的一个全新的客户群，”埃德雷 尔说，“对未来的电影界，三维打印是一个创新。该 技术提供了梦幻般的机会，因为比传统模型的构建，
它通常更快，更精确，更经济。” 有关更多信息，请访问
