    摘要： A method for enabling an extrusion-based AM 3D printing system to handle individual 3D parts of a print job having at least two 3D parts. The method includes slicing the print job to generate a set of slices for the digital 3D representations of the 3D parts. Each slice having geometrical data defining boundaries of a layer of AM feedstock material for printing each 3D part taking into account said boundaries. Generating for each 3D part an individual set of geometrical data taking into account said geometrical data, wherein each individual set of geometrical data includes geometrical data defining the boundaries of the layers of AM feedstock material that are to be taken into account for printing the respective 3D part. An AM 3D printing system that is adapted to perform said method.

    摘要： Method and system arranged for obtaining an electronic 3D model of a 3D object to be fabricated. The method further including generating control instructions based on the electronic 3D model and process parameters of the fabrication process, determining a mesh model representing the electronic 3D model, the mesh model including elements each having at least one property that is affectable by at least one of the process parameters, and performing simulation of the fabrication process in time using the control instructions, the mesh model and the process parameters. The simulation includes establishing a deviation of the at least one property relative to a reference thereof for each element of the mesh model, wherein the deviation is induced by at least one of the process parameters, and establishing an adaptation for the at least one property of each element of the mesh model to compensate for the deviation. The adaptation is applied to the process of generating control instructions to obtain at least one adapted control instruction.

    摘要： A three-dimensional modeling system for creating an object having a three-dimensional modeling printhead, wherein the printhead is attached to positioning means spatially moving at least one of the printhead and the object being printed relative to one another. The printhead having a tubular feed member and a nozzle arranged at one end of the tubular feed member, the nozzle having a nozzle outlet for dispensing modeling material modeling material, and a nozzle tip, for interfacing previously deposited tracks of modeling material on the object to be created. The tubular feed member having a feed channel for feeding the modeling material to the nozzle outlet. The system further having modeling material feeding means arranged at an end of the tubular feed member opposite of the nozzle, wherein the modeling material feeding means are arranged for exerting a pressure on the modeling material within the feed channel towards the nozzle. The system further having a pressure determining means for determining a first parameter indicative for a pressure exerted on the modeling material. The system further having a control system arranged for controlling the modeling material feeding means based on the determined first parameter indicative for a pressure exerted on the modeling material. A method of three-dimensional modeling using the system.
