By incorporating much of the technology which has been proven by GE in the healthcare sector over four decades, the new CT system is up to 200 times faster than conventional 3D CT inspection and offers important additional quality control features, including exact 3D defect location and classification, wall thickness analysis to allow dimensional control and actual - CAD data comparison.
Fast atlineCT with GE’s new speed|scan CT System allows up to 100% 3D inspection of castings and composite samples
The scanned samples are automatically analysed with GE’s newly developed high-speed 3D evaluation algorithms
GE’s speed|scan atlineCT is suitable for any production line where there is a constant requirement for stringent quality control of light metal castings or composite structures but is particularly targeted at the automotive and aerospace sectors.
“The new inspection system can reduce typical scan times for an engine cylinder head from several hours with conventional fan beam CT to less than two minutes,” says Oliver Brunke, Lead CT Product Manager for the Inspection Technologies business, “This means that all of the benefits of 3D compared with 2D inspection can now be realized at the production line. These include benefits such as reduction in reject rate by analyzing position and form of defects which may be machined out by subsequent processes to prevent unnecessary failure sentencing and by accurately checking work piece geometry and dimensions, so that form and size deviations can be easily identified and corrected at an early stage of the production process. Finally, depending on their size and absorption behaviour even foreign materials like inclusions or sand core remains may be detected, located and classified according to its density and position.”
The modified GE medical scanner in speed|scan atlineCT system uses Helix multi-line technology, where a gantry with an X-ray tube and corresponding multi-line X-ray detector rotates around the work piece, which is being passed through the gantry on a conveyor belt. The work pieces are scanned at speeds of up to several millimeters per second, and are automatically assessed with the aid of GE’s own speed-optimized 3D Automatic Defect Recognition (ADR) algorithms. Inspection is carried out using a new workflow concept, where the work piece is loaded onto the conveyor belt of the system which is located adjacent to the production line. The continuous CT scan takes place and the software begins volume reconstruction and optimization. The work piece is unloaded and a new work piece placed on the belt for scanning. At the same time, 3D ADR is taking place on the first work piece volume to allow rapid sentencing. The second and subsequent work pieces then follow the same procedure.
The new speed|scan atlineCT inspection system can handle work pieces up 300x400x800mm in size and up to 50kg in weight and its robust design allows 24/7 operation. Its containing cabinet is suitable for industrial environments with dust protection and thermal isolation and the radiation safety cabinet offers full protective installation according to the German RÖV standard and the US 21 CFR 1020.40 standard.http://ge-mcs.com/speedscan

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
