3D打印和3D扫描专家破解了海洋8钻石项链抢劫

海洋8,最新的明星云集的Hollywood heist movies, recently made its UK debut yesterday with a 3D printer in a starring role.

坐在帮派车间后面的台式机上Makerbot复制器Z18seamlessly creates a Cartier diamond necklace that convinces an unwitting Anne Hathaway (Daphne Kluger in the film) that it’s the real thing.

Now, where many tech enthusiasts might grimace at the idea of desktop 3D printer achieving such a remarkable feat, I decided to put together my own crack team of 3D experts and prove how exactly, you could 3D print your own diamond necklace.

3D scanning glasses

在电影中,海伦·邦纳姆·卡特(Helen Bonham Carter)(玩玫瑰魏尔(Rose Weil))使用一双常规玻璃眼镜完成了原始卡地亚项链的3D扫描。数据是无瑕疵的CAD文件,然后将无线传输到准备3D打印的团队的其余部分。

尽管Bonham Carter在影片中采用了更经典的Wayfairer风格,但3D扫描眼镜确实使我想起了一些东西……

The Leo is a handheld 3D scanner made byartec3d。According to Andrei Vakulenko, Artec’s Chief Business Development Officer, the solution is simple: “All that is left to do is to reduce our Artec Leo handheld 3D scanner to the size of a pair of glasses and develop a way of sending the file over WiFi at a speed of hundreds of gigabytes per minute,” he explains. “At the moment this takes several hours. But all is coming soon.”

Florian Bommier,应用程序工程师SHINING 3D,建议设计眼镜的计划;“ 2个相机将位于眼镜的侧面,也就是说,隐藏在Wayfarer眼镜的任何一侧,“和投影仪在中心”。然而,他指出:“我们需要更改投影仪与红外线合作,以使人们的眼睛看不见预测的模式。”

等一下,光芒呢?

固有的sparkle钻石肯定确实对我们的3D扫描仪制造商构成了巨大的挑战。鲍米尔(Bommier)缺少用细粉来使粉红色的项链和细粉末变钝,也建议摄影测量法as a suitable approach.

“This process is commonly used in art and for large scans,” Bommier explains, “Google uses this process [to produce] 3D data of cities.”

CAD雕塑家和珠宝设计师摩根·莫里(Morgan Morey), winner of the2017 3D印刷行业奖奖杯设计竞争,也支持这个想法。根据莫雷(Morey),制作钻石项链的CAD型号,“需要几个小时,只需要半个体面的图片或图表。”

3D印刷钻石

Though detonation nanodiamonds (produced from an explosive mix of TNT and RDX) may have proved to bea 3D printer’s best friend when added to medical implants, achieving an optically clear and shiny由于材料的层和可塑性,在FFF/FDM 3D打印机上的石头在技术上是不可行的。

莫里解释说;

“即使您挫败了石头,3D打印的石头也不会反射 /折射。”

至少对未经训练的眼睛复制钻石的最有效方法是使用立方锆 - 这是通过在电影中使用锆的事实。Morey指出,可以在网上挑选Cubic锆石。

Making the necklace settings

借助CAD数据,照片,图表和钻石,在此要做的就是为石头制作设置。在CAD珠宝制造商经常执行的过程中,设置将被打印为确切的规格,即cast和镀镀 - 一项可以服用训练有素的技术员/珠宝商的工作Mindy Kaling/Amitain the film, just a few days to complete.

Et voila! Your 3D printed Cartier diamond necklace is complete.
