The AccuForm® technologie allow to generate three-dimensional objects starting from CAD-generated solid or surface models A temperature-controlled head extrudes thermoplastic material layer by layer. The designed object emerges as a solid three-dimensional part without the need for tooling. The process begins with the design of a conceptual geometric model at a CAD workstation. The design is imported by a proprietary software, which mathematically slices the conceptual model into horizontal layers. Then it automatically generates supports if needed and creates the toolpaths. The data is now sent to the generation system system. The system operates in X, Y and Z axes building the model one layer at a time. Thermoplastic modeling material, feeds into the temperature-controlled FDM extrusion head, where it is heated to a semi-liquid state. With high precision, the head extrudes and deposits the material in ultra-thin layers onto a fixtureless base. Each layer then bonds to the previous one and solidifies. The AccuForm® technology uses soluble supports structures that are remove using an ultrasonic cleaner.
