约翰教授哈特和Jamison马萨诸塞州理工学院（MIT）机械合成小组的Go发表了一篇文章，展示了改进的FFF 3D打印过程，将基准3D打印机留在灰尘中。
Named ‘FastFFF’, (Fast Fused Filament Fabrication) the method is powered by a souped-up printhead and a faster gantry system, producing objects at a rate around seven times faster than your average desktop 3D printer. Don’t believe us? Check out the video below.
从小时到几分钟
意识到当前台式FFF 3D打印机的局限性，许多项目正在寻找加快过程并在几分钟内生成复杂对象的方法。最近，密歇根大学的一个团队分享了他们的算法capable of cutting print times in half。新的3D打印方法也引入了higher production speeds，但他们通常缺乏平均FFF的低成本经济学。
通过将高速与具有成本效益的材料结合起来，Hart和Go的FastFFF流程有可能使3D打印机用户两全其美。

In place of pinch wheel gears, filament is fed through the FastFFF extruder using a screw-based system. A laser heated polymer liquefier is added to the print head, and this is moved by a servo-driven parallel gantry system, achieving “high extrusion force, rapid filament heating, and fast gantry motion.”
通过这些修改，FastFFF 3D打印机能够达到每小时127厘米立方体的体积构建速率，这是根据作者“以可比分辨率大约比商业台式FFF系统大7倍”。以最大速度，挤压率最多比记录的基准率高14倍a previous study来自机械合成组。
商业可用性
Of course, the true potential of FastFFF process will only be fully realised if the system can be made commercially available. The researchers have said that they are considering options to bring the 3D printer market, looking to potentially set up a spin off company for the machines, or link with an existing manufacturer. In further development, the team also hope to be able adapt the process to work withhigh-temperature thermoplastics，像窥视和复合材料。
