A Roll Powder Sintering Additive Manufacturing Technology

Abstract

This paper describes the roll powder sintering (RPS) technology providing breakthrough advantages for dominant rapid prototyping and manufacturing (RP&M) processes that are currently on the market. The RPS based on ribbon perforation where a powder needs to be poured, while it is being rewound. When the whole component roll is rewound, it is ready for a sintering plant. This technology has increased reliability, higher precision up to 77000 dpi, lower cost and power consumption. Processing time of plastic, ceramic, metal and other objects 1 m3 (or more) in volume directly from a 3D CAD model with a layer thickness of 30 μm is about 1 hour.
