尽管MarkForged broke new ground借助能够制造复合材料的第一台3D打印机，用户可以用碳纤维加强尼龙零件，从而使用传统的碳纤维上色技术从未做出从未做出新的几何形状。然而，马萨诸塞州的初创公司并不是唯一希望彻底改变我们制作复合材料的人。不可能的对象has its own take on printing with materials like carbon fiber. We’ve covered the Chicago firm in the past,when they received $2.8 million in funding, but, now, the company has been more open about their composite-based additive manufacturing (CBAM) process, going into greater detail about how it works.
与Markforged的技术不同，该技术将连续的碳纤维链供应到可以与FFF尼龙一起放置的特种打印头，不可能的物体使用的技术几乎类似于MCOR和Inkjet 3D印刷的选择性沉积层压技术的组合。该工艺是添加剂和减法制造的结合，将塑料喷墨涂在织物片上，例如丝，聚酯，凯夫拉尔，棉花或碳纤维，融入所需的形状。然后将形状切出并互相堆叠在烤箱中并融合在一起之前。然后，打印是干净的，清除了多余的材料并揭示了最后一部分。
At the moment, Impossible Objects is at the prototyping stage. The process is not yet at the speed or scale that the company is aiming for. And, though extrusion processes may offer advantages in terms of possible geometries, theWall Street Journal指出，由于存在极大的喷墨打印机，因此可以将技术扩展以生产大量的车辆零件。当然，这将对汽车行业产生巨大影响，这在很大程度上依赖于碳纤维来产生强大的轻量级零件。
Both MakerForged and Impossible Objects offer a completely new take on 3D printing functional objects that meet the standards of critical industrial applications. With the benefits of 3D printing composite parts having the potential to replace injection molding, I wonder if those two firms won’t be the only ones attempting to do so.
