摘要： The present invention provides an RP system which can directly use hot melt polymers for fabricating porous 3D construct for cell culture and other biomedical applications based on a CAD design. To realize the direct use of polymer hot melt, the RP system uses a hot melt chamber which is mounted on a robotic dispensing ann or a XYZ motion control system. The hot melt chamber is equipped with a delivery mechanism to force the molten polymer passing through a nozzle. The extruded polymer thin filament deposits onto the positions according to the computer generated model, in a layer-by-layer fashion, similar to FDM. The present invention can use any type of thennal plastic polymer pellets, beads, particles, which are suitable for extrusion and injection molding, as well as composites of two or more different thermal plastic polymer blends, inorganic particle/thennal plastic composites.

摘要： A processing installation for devolatilization of polymer melts comprises a first extruder and a second extruder arranged downstream thereof in a direction of conveyance. The first extruder comprises several rotatably drivable first shafts which are provided with first treatment members and several devolatilization zones with associated devolatilization ports. Correspondingly, the second extruder comprises several rotatably drivable second shafts which are provided with second treatment members and several second devolatilization zones with associated devolatilization ports. The first treatment members have an external diameter which is smaller than or equal to that of the second treatment members. A devolatilization unit is arranged in a transfer zone which interconnects the extruders. The devolatilization unit comprises a perforated plate and a clearance arranged downstream in the direction of conveyance. A control unit is configured in such a way that when the processing installation is operated, the speed of the second shafts is lower than the speed of the first shafts. The processing installation allows a high devolatilization performance and a high polymer throughput to be achieved at the same time. A throttle is arranged in the transfer zone upstream of the devolatilization unit when seen in the direction of conveyance, with the position of the throttle being adjustable by means of the control unit.

摘要： In a two-shaft extruder, a pair of rotor shafts (1) is rotatably arranged such that the closer to the head end of the pair, the smaller the distance between the pair. The pair of rotor shafts (1) is respectively provided with screw blades (2) mounted on the head end side of the pair. The rotor shafts (1) are adapted such that one screw blade (2a) enters gaps of the other screw blade (2b). Drive devices (M) for rotationally driving the pair of rotor shafts (1) are mounted on the respective base ends of the pair. The extruder has a screw blade contact prevention mechanism (SS) which, when the pair of rotor shafts (1) is driven, prevents the pair from having a phase difference greater than a predetermined level.
