The SDG label(s) above have been assigned by OSDG.aiAbstract: The material in laser additive manufacturing is traditionally supplied in the form of powder or sometimes wire. A technique called CYCLAM was recently presented which is a fast and direct recycling technique which lowers the number of steps that need to be taken in typical recycling, allowing for a more circular economy. The CYCLAM technique proposes that waste metal is directly recycled through laser cutting or laser ablation of one sheet and the molten droplet is directly deposited onto a new product and can be used for additive manufacturing or cladding. The technique also can also use materials that otherwise are not available as powder or wires. Because of the novelty of the technique, it is still scarcely studied, and many aspects still needs to be understood. This paper focusses on high-speed imaging of the technique to understand the droplet behaviour. The material removal of the feeding sheet was done with Remote Fusion Cutting. Different power levels lead to different drop geometry and flight pattern of the drops where the drops at higher power are pushed further forward. The influence of the laser power on the shape of the deposited track can be seen from cross sections of the cladded track where higher power means that more power is transmitted through the feeding sheet and onto the substrate which creates a smoother surface
