Method for error detection and for local limitation of a cause of the error in an installation for machining a workpiece which is preferably formed at least in sections from wood, a wood material, and/or a synthetic material, with the installation having several segments. The method comprises the steps: Detecting a status information which relates to a workpiece throughflow in at least two segments of the installation; determining whether there is an error on the basis of the status information; if there is an error, identifying in which of the at least two segments of the installation the error is present for local limitation of the cause of the error; and outputting a signal containing the information regarding which segment the error is in.

Method for error detection and for local limitation of a cause of the error in an installation for machining a workpiece which is preferably formed at least in sections from wood, a wood material, and/or a synthetic material, the installation having several segments, comprising the steps: Detecting a workpiece parameter in at least two segments of the installation; determining whether there is an error on the basis of the detected workpiece parameter; if there is an error, identifying in which of the at least two segments of the installation the error is present for local limitation of the cause of the error; and outputting a signal containing the information regarding which segment the error is in.

According to one embodiment, a manufacturing control system includes a reference data creating unit, first, second and third data storing units, first, second and third data extracting units. The reference data creating unit creates reference data including a reference time related to a product. The first data storing unit stores data related to parts acceptance inspection and related to assembly of the product. The second data storing unit stores data related to inspection in manufacturing. The third data storing unit stores data related to quality assurance inspection and of acceptance inspection at a customer site. The first data extracting unit extracts data related to latest parts acceptance inspection and related to latest assembly of the product. The second data extracting unit extracts data related to inspection in latest manufacturing. The third data extracting unit extracts data related to latest quality assurance inspection and of latest acceptance inspection.

A powder quality control system includes a powder container, a piston, and at least one sensor. The powder container is configured to contain a powder sample. The piston is configured to compact the powder sample in the powder container. The at least one sensor is configured to measure at least one parameter when the piston compacts the powder sample to facilitate determining a powder quality measurement for the powder sample.

Techniques are described to gather information from an end user relating to fabrication process failures in a standardized manner. This information may be provided to an additive fabrication device manufacturer and analyzed by the manufacturer. Analysis may include identifying patterns in the data to identity problems relating to an additive fabrication device, software used to operate the device and/or user operations. Identification of such patterns may aid in selecting and/or generating support solutions to be provided the end user, or to improve the additive fabrication device and/or software.

A method and an apparatus for collecting a powdered material after a print job in powder bed fusion additive manufacturing may involve a build platform supporting a powder bed capable of tilting, inverting, and shaking to separate the powder bed substantially from the build platform in a hopper. The powdered material may be collected in a hopper for reuse in later print jobs. The powder collecting process may be automated to increase efficiency of powder bed fusion additive manufacturing.

A method of additive manufacture suitable for large and high resolution structures is disclosed. The method may include sequentially advancing each portion of a continuous part in the longitudinal direction from a first zone to a second zone. In the first zone, selected granules of a granular material may be amalgamated. In the second zone, unamalgamated granules of the granular material may be removed. The method may further include advancing a first portion of the continuous part from the second zone to a third zone while (1) a last portion of the continuous part is formed within the first zone and (2) the first portion is maintained in the same position in the lateral and transverse directions that the first portion occupied within the first zone and the second zone.

A method and an apparatus pertaining to recycling and reuse of unwanted light in additive manufacturing can multiplex multiple beams of light including at least one or more beams of light from one or more light sources. The multiple beams of light may be reshaped and blended to provide a first beam of light. A spatial polarization pattern may be applied on the first beam of light to provide a second beam of light. Polarization states of the second beam of light may be split to reflect a third beam of light, which may be reshaped into a fourth beam of light. The fourth beam of light may be introduced as one of the multiple beams of light to result in a fifth beam of light.

A system and method for monitoring manufacturing machines that includes a sensor system that monitors a plurality of machines, wherein the sensor system is comprised of a set of current transformers, and wherein the set of current transformers transform electric currents to the plurality of machines into electric signals; an activity processing engine, wherein the activity processing engine generates diagnostic metrics from the electric signals for each machine from the plurality of machines; and a management platform configured to provide access to diagnostic metrics of the plurality of machines.

An article is provided with a web of polymer fibers forming a scrim with openings between the polymer fiber elements. A particulate is distributed in, or on the polymer fiber in a quantity to make the scrim detectable by X-ray detection or magnetic detection. One or more layers are laminated to the scrim. A process for detecting a multi-layered laminated scrim-containing article with magnetic or X-ray detection equipment in a production setting is also provided. With process implementation article loss in a product can be detected thereby reducing precautionary product discard.
