<pre>The world's first carbon-bicycle printed on a 3D printer interested the CIA

Last month, Arevo, a young company from the Silicon Valley, presented a prototype of a bicycle, completely printed from carbon on a 3D printer. And in this already received a generous investment in the development of technology, and the interest of the daughter structures of the CIA. So far, no one in the world knows how to create solid, finished structures from carbon fiber – this direction has great prospects.

In the traditional view, sheets or individual fibers from carbon are superimposed or wound on a framework layer by layer, then they are fastened with thermosetting resins, all of which solidifies and so a detail is born. Then components need to be put together, and some high-quality frames for bikes made of carbon can have up to 500 parts. Long, expensive and we need extreme accuracy, strict quality control, which makes serial production difficult.

 Bicycle

The company Arevo has developed a robot for 3D printing, which draws a continuous carbon fiber and stacks it layer by layer along the entire profile of the bicycle frame. To this end, engineers designed a special swiveling “sewing” head and replaced the binder resin with PEEK industrial thermoplastics (polyether ketone). In theory, there is no problem to use a carbon-Kevlar pair instead of carbon fiber, but the main advantage of the novelty is special software for modeling and printing three-dimensional structures.

It was PO that interested government intelligence officers, because a bicycle is just a simple and understandable example. The technology is scalable and with its help it is possible to create the wings of convertoplanes, hypersonic missile shells, shells for combat drones and much more. The transition to 3D printing from carbon fiber promises, as a minimum, a reduction in the production of complex parts from months to weeks or even days.
