V2_3D dataset of the X-ray Computed Tomography and plugin graph results
(2023) Chahid, Younes; Packer, Chris; Tawfik, Ahmed; Keen, Joel; Brewster, Nick; Beardsley, Mat; Morris, Katherine; Bills, Paul; Blunt, Liam; Atkins, Carolyn; Tammas-Williams, Samuel
V2: This dataset is an updated version of the previous Part 2/2 (http://dx.doi.org/10.5286/edata/901). This version includes updated Part 2.c graph outputs. Part 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".
Outgassing Measurements for "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing"
(2023-09-19) Wells, James; Westsik, Marcell; Chahid, Younes; Macleod, Alastair; Kotlewski, Richard; McPhee, Scott; Orr, Jonathan; Pimentel Espirindio e Silva, Misael; McKegney, Scott; Cochrane, William; Breen, Ciarán
Dataset contains raw text files from outgassing measurements of Wire-Arc Additive Manufactured (WAAM) samples presented in the conference paper "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing" (SPIE Optomechanical Engineering 2023) Files contain the pressure and temperature measurements used to calculate outgassing rates for the WAAM samples. For details of the analysis see the paper and the associated GitHub repository. README contains information on raw file format.
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, Ciarán
Files 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"
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, Carolyn
This 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".

Multi Threshold Comparator Avizo Plugin
(2022-12) Chahid, Younes; Packer, Chris; Tawfik, Ahmed; Keen, Joel; Beardsley, Mat; Morris, Katherine; Bills, Paul; Blunt, Liam; Atkins, Carolyn; Tammas-Williams, S
Part 1/2: The Multi Threshold Comparator is an Avizo software plugin that assist users in choosing the threshold value when using X-ray Computed Tomography data for porosity analysis. The objective of the developed Avizo plugin is to compare multiple threshold types (Otsu, global and local) across a range of values, based on a previously measured hole, to eventually assist the user in choosing the suitable threshold value. The plugin .zip file is composed of the .pyscro and .rc files to be placed in Avizo installation folder. The hole data to be analysed needs to have a minimum of 2 slice images, and the orientation of the stack needs to show the diameter as circles. Further information can be found in the readme file and detailed use of the plugin is in the study titled "Development of a modular system to provide confidence in porosity analysis of additively manufactured components using X-ray computed tomography". Part 2/2: This second half of the dataset is composed of sample data used in the study and their outputs which can be found in DOI: http://dx.doi.org/10.5286/edata/901
