Whenwe wrote about the SolidWorks World博览会 - 专门用于3D建模及其应用 - 上周，我提到“一家神秘的公司叫标记锻造”将在活动中首次亮相。这是神秘的，因为在文章发表时，商标伪造的网站上没有任何内容。那是因为该公司正在等待在Solidworks World推出其新的原始碳纤维3D打印机。
Mark One Carbon Fiber 3D打印机在活动中引起了巨大的飞溅，显示了一台几乎无缝打印的机器，通过称为连续细丝制造的过程，零件包含在尼龙中，并充满了碳纤维。观看下面的视频，您可以看到两个不同的丝从两个不同的线轴喂入两个挤出机头。据该公司称，通过放下长长的连续碳纤维填充，印刷品可以达到20倍的刚度，该刚度比ABS和5倍强。
Markforged由Gregory Mark创立，是Aeromotions的衍生产品，这是计算机控制的赛车机翼的制造商。尽管碳纤维强大且轻巧，但以前可以通过CNC铣削获得碳增强零件，这是一个昂贵且劳动力密集的过程。在3D打印市场中没有其他选择，Mark被导致了Mark One。这个新过程使他能够以比铝更高的强度比率打印零件，从而领先创造者to tell Popular Mechanics，“”我们说这就像常规的3D打印机做表格。雷电竞app下载我们确实形成和功能。“
It’s not extraordinary for 3D printers to attempt such a process.原始帕斯塔demonstrated that it has developed a carbon reinforced PLA and Nathan Armstrong, a composite specialist, is pursuinga 6-axis continuous carbon fiber reinforcement printer。据我所知，Markforged是为此目的执行设备的第一台桌面3D打印机，并具有连续的碳加固，而不是在整个塑料原料中部分混合的碳的一部分，如Proto-Pasta所示。
The company’s founder explains that his CFF process could serve the automobile industry and help build stronger prosthetics as well:
“有一群对假肢感兴趣的人。”他说。“有一个完整的组件。它必须适合您的身体。这比科学更具艺术作用，您想打印出一大堆不同的版本并进行测试，但是当您拥有最终版本时，您想完全做到这一点，但确实很强大。[带有]打印机，一旦您想使其结实，就可以用复合材料进行打印。
It’s a material that everybody knows, but probably most people haven’t used. So we made the price low and you can start using it. We wanted to make it really easy for people to start printing with it, so they can explore prosthetics, custom bones, tools and fixtures.”
因为打印机是一个dual-extruder机器,它can also print other materials, as well, such as the company’s own PLA, nylon, and, even, fiberglass filaments for fiberglass reinforced parts. The machine has a build volume of 305mm x 160mm x 160mm (12″ x 6.25″ x 6.25″), modelled after the long-axis CNC machines. It can achieve a layer resolution of 100 microns, when using the FFF process, and 200 microns, when using the company’s patented Carbon Filament Fabrication technique. The Mark One can also be connected to via WiFi, USB or SD card. Using kinematic coupling, the manufacturer claims that the bed is easy to level.
The Mark One is set to be released in February at a price of around $5,000, which Mark hopes is affordable enough for average consumers to afford.
