摘要： The present invention relates to a system and a method for optimizing printing parameters, such as slicing parameters and tool path instructions, for additive manufacturing. The present invention comprises a property analysis module that predicts and analyses properties of a filament object model, representing a constructed 3D object. The filament object model is generated based on the tool path instructions and user specified object properties. Analysis includes comparing the predicted filament object model properties with the user specified property requirements; and further modifying the printing parameters in order to meet the user specified property requirements.

摘要： A tool used to direct the pressure applied to features of a plastic laminate part layup during co-curing or co-bonding is manufactured using direct digital manufacturing techniques. A CAD drawing representing the tool is generated and converted into digital data file suitable for controlling the operation of a rapid prototyping machine. The tool is formed in the rapid prototyping machine by additive layering of material until the features and dimensions of the layered material correspond to the CAD drawing. The resulting tool exhibits geometries and dimensions virtually identical to the theoretical dimensions of the CAD model of the tool.

摘要： An automated computer-implemented method for generating commands for controlling a computer numerical control machine to fabricate an object from a workpiece. The method includes the steps of: (1) determining a first set of Z coordinates for machining a first set of Z level planar slices with a first tool; and (2) determining a second set of Z coordinates for machining a second set of Z level planar slices with the first tool. The second set of Z coordinates is partitioned into one or more subsets. Each subset corresponds to a pair of adjacent Z coordinates belonging to the first set of Z coordinates. A distance between the Z coordinates of each subset is a unit fraction of a distance between the Z coordinates of the pair of adjacent Z coordinates which corresponds to each subset.

摘要： A system is disclosed for cutting shapes from slabs of easily machinable material, such as plastic foam, under computer control. These shaped slabs can then be piled and glued together in order to build large complex volumes, to be used as models, molds or cores of fiber-reinforced objects. The slab of material is rotated around a fixed axis of rotation, while a cutting wire is driven in translation and tilted at various angles within a plane parallel to or containing said axis of rotation. The cutting action of the wire results from electrically induced heat and/or abrasive motions of the wire in its own direction. This cutting machine is used as a peripheral of a microcomputer, and receives from this microcomputer the signals necessary to control the electric motors driving the rotation of the slab of material and the motions of the cutting wire.
