“…Upon successful printing of the samples, they were scanned (0.2° rotation angle) using a skyscan‐1273 (Brucker, Germany) micro‐X‐Ray computed tomography setup for porosity analysis. μXCT is a well‐established nondestructive testing method that is extensively used for porosity characterization, [ 34 ] in operation the X‐rays passed through a mounted rotating sample and the image projections were taken at different angles. These projected images were then further reconstructed in 3D with the help of software for analyzing the internal details of the samples such as porosity, pores visualization, and pores characterization.…”

Owing to geometrical degrees of freedom, low cost, and ease of realizing complex structures polymer additive manufacturing has emerged exceptionally well. Even with rapid evolutionary growth additive manufacturing lacks sound quality mainly including inherent porosity and surface roughness compared to their counterparts (conventional manufacturing processes) due to the involvement of several printing parameters in AM processes. This quality‐based comparative assessment presents the influence of build /layer height on the porosity (using Micro‐X ray Computed Tomography) and surface roughness (in build direction) of additively manufactured Thermoplastic Polyurethane (TPU) (due to its versatile properties in applications like wearable electronics and biomedical) using three different polymer additive manufacturing processes namely SLS (Selective Laser Sintering), FDM (Fused Deposition Modeling), and SLA (Stereolithography). Along with porosity, an in‐depth pores characterization is also performed to understand the geometrical feature and severity of pores present in each sample of the AM process. Results were compared at last to make concluding remarks.This article is protected by copyright. All rights reserved.

“…IBSim has great potential for reducing material waste due to part rejection. A review was made of CT-based measurement techniques used for assessment of quality of bioengineering components [ 201 ]. Due to the critical nature of medical applications, FEA is often used [ 202 , 203 ], especially in the design phase for new device development [ 204 ].…”

Image-Based Simulation (IBSim) is the process by which a digital representation of a real geometry is generated from image data for the purpose of performing a simulation with greater accuracy than with idealised Computer Aided Design (CAD) based simulations. Whilst IBSim originates in the biomedical field, the wider adoption of imaging for non-destructive testing and evaluation (NDT/NDE) within the High-Value Manufacturing (HVM) sector has allowed wider use of IBSim in recent years. IBSim is invaluable in scenarios where there exists a non-negligible variation between the ‘as designed’ and ‘as manufactured’ state of parts. It has also been used for characterisation of geometries too complex to accurately draw with CAD. IBSim simulations are unique to the geometry being imaged, therefore it is possible to perform part-specific virtual testing within batches of manufactured parts. This novel review presents the applications of IBSim within HVM, whereby HVM is the value provided by a manufactured part (or conversely the potential cost should the part fail) rather than the actual cost of manufacturing the part itself. Examples include fibre and aggregate composite materials, additive manufacturing, foams, and interface bonding such as welding. This review is divided into the following sections: Material Characterisation; Characterisation of Manufacturing Techniques; Impact of Deviations from Idealised Design Geometry on Product Design and Performance; Customisation and Personalisation of Products; IBSim in Biomimicry. Finally, conclusions are drawn, and observations made on future trends based on the current state of the literature.
