- 3D dataset of the X-ray Computed Tomography and plugin graph results(2022-12) Chahid, Younes; Packer, Chris; Tawfik, Ahmed; Keen, Joel; Beardsley, Mat; Morris, Katherine; Bills, Paul; Blunt, Liam; Atkins, Carolyn; Tammas-Williams, SPart 1/2: The first half of the dataset is composed of the Avizo plugin, which can be found in the DOI http://dx.doi.org/10.5286/edata/900 Part 2/2: This second half of the dataset is composed of the X-ray computed tomography data used in the study and their outputs. 2.a is composed of the XCT region of interest (ROI) showing the individual micro drilled holes, previously measured in the SEM. 2.b contains the isolated cube ROI used in the porosity analysis. 2.c contains the plugin graph outputs for each hole, when using the Avizo plugin. The XCT data in 2.a and 2.b is a subvolume of the full scan of an additive manufactured flexure containing a reference pin with micro drilled holes, measured in the scanning electron microscope (SEM). The scan settings included a voltage of 145 kV, filament current of 41 µA, number of projections of 1650 and a voxel size of 8.5 µm × 8.5 µm × 8.5 µm. After reconstruction, the scan was converted from 32 bit to 8-bit, aligned to the CAD and resampled, resulting in a voxel size change to 9.4 µm × 9.4 µm × 8.8 µm. Detailed use of the XCT scan dataset and resulting plugin graphs can be found in the study titled "Development of a modular system to provide confidence in porosity analysis of additively manufactured components using X-ray computed tomography".
- CAD file dataset of the ISAAC AM petal re-design project(2023) Westsik, Marcell; Wells, James T.; Chahid, Younes; Morris, Katherine; Milanova, Maria; Beardsley, Mat; Harris, Michael; Ward, Lucas; Alcock, Simon G.; Nistea, Ioana-Theodora; Atkins, CarolynThis dataset contains the .STL files of the Graph and TPMS Additively Manufactured petals. For both designs, an "As Printed" and an "As Postprocessed" version is included. These designs are detailed in the paper submitted to SPIE titled "From design to evaluation of an additively manufactured, lightweight, deployable mirror for Earth observation".
- CAD files from "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing"(2023-07-06) Atkins, Carolyn; Wells, James T.; Westsik, Marcell; Chahid, Younes; Mcleod, Alastair; Bissell, Lawrence; Kotlewski, Richard; McPhee, Scott; Orr, Jonathan; Pimentel, Misael; Cochrane, William; Breen, CiaránFiles contain .step files for the topology-optimised design and the varied wall thickness design. These designs are detailed in the paper submitted to SPIE Optomechanical Engineering 2023 titled "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing"
