摘要： A three-dimensional object model is divided into slices that are targeted for an additive manufacturing process operable to deposit material at a variable deposition size ranging between minimum and maximum printable feature sizes. For each of the slices, a thinning algorithm is applied to contours of the slice to form a meso-skeleton. Topological features of the thinned slice are reduced over a number of passes such that a portion of the meso-skeleton is reduced to a single pixel wide line. Based on the number of passes, a slice-specific printable feature size within the range of the minimum and maximum printable feature sizes is determined. An adjusted slice is formed by sweeping the meso-skeleton with the slice-specific printable feature size. The adjusted slices are assembled into an object model which is used to create a manufactured object.

摘要： The invention relates to a plausibility checking method for rapid prototyping devices, in particular for stereolithography devices. In this connection, input data (14) is checked which is present particularly in the form of graphics data and of which every file renders a layer. Every layer comprises a plurality of pixels. The component to be printed in the respective layer is produced based on output data by the rapid prototyping device.
The input data of two consecutive layers is checked and the sum of all pixels to be exposed is determined for every layer. A signal (22) is output in particular as a warning signal (26) when the pixel sum of a following layer is larger than in the previous layer by a predetermined factor.

摘要： Systems, methods, and media for additive manufacturing are provided. In some embodiments, an additive manufacturing system comprises: a hardware processor that is configured to: receive a captured image; apply a trained failure classifier to a low-resolution version of the captured image; determine that a non-recoverable failure is not present in the printed layer of the object; generate a cropped version of the low-resolution version of the captured image; apply a trained binary error classifier to the cropped version of the low-resolution version of the captured image; determine that an error is present in the printed layer of the object; apply a trained extrusion classifier to the captured image, wherein the trained extrusion classifier generates an extrusion quality score; and adjust a value of a parameter of the print head based on the extrusion quality score to print a subsequent layer of the printed object.

摘要： In a method for additive manufacturing of at least one metallic or ceramic component, before at least one green part is built up layer by layer in a printing device, a support layer is applied to a surface of a printing support having recesses, so that the green part is built up layer by layer on the support layer, whereupon the green part lying on the printing support is removed from the printing device and unpolymerized material is removed from the green part, wherein removed material is collected in the recesses of the printing support or is drained off through the recesses, and wherein the cleaned green part is debinded and sintered.
