A group of students known as the MIT Rocket Team has successfully fired a fully 3D printed rocket.
In a post written by the group’s Charlie Garcia，团队解释了塑料火箭电机“达到超音速流并产生推力.” The MIT Rocket Team is an “独立学生团体专注于火箭相关的项目，已建立了14年以上。
3D印刷火箭s
为了创建只有两个部分的火箭，该团队使用了标记两个3D打印机和Onyx尼龙材料。由Markforged开发，将尼龙材料与微碳纤维结合使用，以增加强度和耐热性。
Heat resistance was definitely necessary in this case as the team explained the rocket survived initial testing with only slight erosion of the rockets’s throat. So much so, the team were able to fire the rocket again, although without quite the same effect. US researchers have最近探索了像这样的复合塑料丝的导热率.
使用标记标记两个展示了与工业金属3D打印机相比，低价3D打印机的潜力large-scale rocket companies like Aerojet Rocketdyne. For this reason, the Markforged Mark Two has been由我们的读者提名为3D印刷行业奖.
进入金属？
In terms of future plans, the MIT Rocket Team hope “探索较大的电动机，更具弹性的电动机，甚至有可能飞行硬件！”这意味着最近有关桌面金属和Markforged的新闻可能会鼓励该小组。这两家公司今年都以比目前的工业金属打印机低得多的价格发行了金属FDM 3D打印机。
桌面金属本周终于revealed the 3D printer it has been working on, while Markforged has detailed plans to build a3D打印机农场和即将推出的金属X 3D打印机.
