This paper reviews key ideas and performances of the enhanced roll powder sintering (RPS) by inkjet technology. A modification of the RPS technology aims to improve precision, reliability and lower-priced hardware, and power consumption is proposed. RPS allows accomplishing designs, which are impossible, very expensive and difficult to create using other methods. A new version has increased reliability, higher perforation precision (up to 9600 dpi), lower cost and power consumption. It is based on the commercially available inexpensive components. Various specifications of laser and inkjet perforation of one-layer, compressible ribbon are reviewed. An enhanced RPS technology could make a significant contribution to the micromanufacturing, micro-forming, jewellery, stomatology and many other industries where there are needs of processing plastic, ceramic, metal and other objects. The RPS technology offers a new way to produce more accurate micro-scale products with better smooth surfaces. It has the potential to create parts about 1-1.5 l (or more) in volume with layer thickness about 3-5 μm and print width of 0.297 m directly from a 3D CAD model with processing time about an hour. The advantages of the inkjet perforation are compared to the RPS prototype based on laser systems.

“…It appears feasible to modify commercially available printing machine similar to "COMEXI FI-2108 CNC" (COMEXI GROUP Company, print width 1670 mm and maximum printing speed 600 m/min) for RPS with help of laser or inkjet [27] perforation, powder and compression systems and thus to achieve object's roll forming performance ~1.5 m 3 in volume per hour with layer thickness ~25 µm. As a result, similar modification could exceed volume build rate of the modern generation of SLS printers "ProX™ SLS 500" (3D Systems Corporation) hundred fold.…”

Abstract:The article considering the problem of quick transformation of solids of revolution into raster layer for Roll Powder Sintering (RPS) additive manufacturing technology. The author describes the algorithm for solving this problem. This work is devoted to the development and the validation of the impetuous algorithm for converting the 3D coordinates of a solid of revolution to spiral coordinates. It is based on the assumption that one point on the figure of revolution is predetermined multitude of points in the spiral coordinate system and these can be defined without calculations because of symmetry properties. Such method provides to accelerate the performance of the coordinate conversion thousand fold and real time forming objects 1.5 m 3 in volume with layer thickness ~25 µm by non-powerful computers per hour. The proposed algorithm has been extensively tested and proven by numerical examples of several parts of computer aided design models. It is faster than other coordinates transformations and can be extended to the acceleration converting and processing geometry of 3D objects.
