The US company Impossible Objects presents a new technology to produce parts of carbon fibre or other fibre materials like Kevlar.
The technology is called Composite Based Additive Manufacturing (CBAM) and utilises the principles of Layer Laminated Manufacturing (LLM). Sheets of materials are processed with some chemicals which sketch the layers of the 3D designs onto the sheets. After this process the sheets will be stacked in the right order and put into a squeezing machine. Then, the stack of sheets is put into a oven where the the layers are bind together by heat. After the heating process the rest of the materials is removed and a solid object emerges.
As the chemicals are printed onto the sheet by inkjet, common in normal printers, the process could be scaled up and archieve a cost effective way of producing carbon parts.
