20140197576 | DEVICE AND METHOD FOR THE PRODUCTION OF A THREE-DIMENSIONAL OBJECT - The device and the method serve for the production of a three-dimensional object from a solidifiable by a sequential discharge of drops onto an object carrier for the object to be produced, the device including discharge unit with an outlet orifice discharges drops along an axis (s) in a direction to the object carrier, and control means configured to control the motion of the object carrier and the object on the one hand and the outlet orifice on the other hand relative to each other in space, where due to the fact that means are provided for a mutual alignment of the object carrier or the object on the one hand and the outlet orifice on the other hand and that can be controlled by control means, with the axis (s) in a mutually aligned state intersecting a surface of the object carrier or the already produced object, such that a method and a device are provided for the production of a three-dimensional object with geometric overhangs and/or undercuts using solidifiable materials. | 07-17-2014 |
20140191433 | Method for discharging a volume flow - In a method for discharging a volume flow consisting of successive drops to produce a three-dimensional object of solidifiable material present in a fluid phase, the fluid phase of the material is introduced into a material storage means. A pressure (p) is applied to the fluid phase, in order to discharge the material in drops out of a cyclable outlet opening to build up the three-dimensional object in a construction chamber. A method is provided for achieving a constant, discontinuous volume flow by the pressure (p) being regulated via a closed-loop control in the event of a change in the viscosity of the fluid phase of the material, while maintaining the other process parameters, to achieve a predetermined drop size. The pressure is applied by a conveying element, the average displacement velocity of the conveying element per discharged drop being converted as a measured variable into the control variable for the closed-loop control. | 07-10-2014 |
20140113017 | DEVICE FOR THE PRODUCTION OF A THREE-DIMENSIONAL OBJECT - A device for producing a three-dimensional object from hardenable material has a construction space ( | 04-24-2014 |
20140070462 | CONTROL METHOD FOR MAPPING - A method for producing a three-dimensional object from solidifiable material, which is either present in the starting state in a fluid phase or can be liquefied, by the sequential discharge of drops from at least one pressurisable material storage device for the fluid phase by means of at least one discharge unit through an outlet provided with a pulsable closure element, the closure element is actuated by means of an actuator and its initial stressing is measured at the operating point by means of the actuator, where the initial stressing is controlled by means of an adjusting element, and a mapping for the elastic deformation of the closure element is determined by means of the actuator actuated by the adjusting element, such that an elastic working range of the closure element is adjusted by means of the adjusting element within the mapping. | 03-13-2014 |
20130224329 | INJECTION-MOLDING MACHINE HAVING AT LEAST TWO TOGGLE LEVER MECHANISMS - An injection-moulding machine for processing plastics has, on a mould-closing unit (F), at least one injection mould ( | 08-29-2013 |
20130071599 | METHOD FOR PRODUCING A THREE-DIMENSIONAL OBJECT FROM SOLIDIFIABLE MATERIAL AS WELL AS AN OBJECT PRODUCED THEREWITH - A method serves to produce a three-dimensional object by additive construction in direct construction sequence from solidifiable material, which is either present in the starting state in a fluid phase or can be liquefied, where multiple material components are discharged alternately in a programmable manner by means of multiple discharge units and configure different parts of the object joined to one another as a result of the discharge, where the geometric proportions obtained during discharge already correspond to the object, and because the material components form between them either edge regions merging into one another without boundaries or boundary regions of the different material components abutting one another without joining, a method and an object produced therewith can be provided, in which boundary and edge regions are formed “as if from one piece” between different material components even in the case of complex geometries. | 03-21-2013 |
