“…Also around this time, the first uses of XCT for inspection of AM parts were taking place. In the paper by Wang et al [35], the authors performed XCT measurements of FDM scaffolds, proving the concept of XCT as a method of non-destructive evaluation (NDE) to measure internal morphology and porosity. Similarly, Williams et al [36] performed XCT on polycaprolactone SLS scaffolds to create finite element analysis (FEA) models and to measure porosity, as well as to inspect scaffolds post-implantation (see Fig.…”

Abstract. The use of X-ray computed tomography (XCT) with additive manufacture (AM) within a medical context is examined in this review. The seven AM process families and various XCT scanning techniques are explained in brief, and the use of these technologies together is detailed over time. The transition of these technologies from a simple method of medical modelling to a robust method of customised implant manufacture is described, and the state-of-the-art for XCT and AM is examined in detail. XCT and AM are identified as having the potential to improve gold standards in both modelling and implant production, and in the conclusions of this review, primary barriers to the increased adoption of AM and XCT technologies are identified in reference to the main applications of XCT and AM technologies. The primary prohibitive factors generally relate to the cost of production across all of the examined applications, as well as the need for further clinical trials in surgical guidance and applications involving implantation.

Such methods have improved the efficiency and reproducibility of manufacturing scaffolds with better biocompatibility for bone tissue engineering.…”

Bone defects arising from a variety of reasons cannot be treated effectively without bone tissue reconstruction. Autografts and allografts have been used in clinical application for some time, but they have disadvantages. With the inherent drawback in the precision and reproducibility of conventional scaffold fabrication techniques, the results of bone surgery may not be ideal. This is despite the introduction of bone tissue engineering which provides a powerful approach for bone repair. Rapid prototyping technologies have emerged as an alternative and have been widely used in bone tissue engineering, enhancing bone tissue regeneration in terms of mechanical strength, pore geometry, and bioactive factors, and overcoming some of the disadvantages of conventional technologies. This review focuses on the basic principles and characteristics of various fabrication technologies, such as stereolithography, selective laser sintering, and fused deposition modeling, and reviews the application of rapid prototyping techniques to scaffolds for bone tissue engineering. In the near future, the use of scaffolds for bone tissue engineering prepared by rapid prototyping technology might be an effective therapeutic strategy for bone defects.

“…Now-a-days CAD is being extensively used in biomedical engineering. [8,[10][11] This development is due to advances in imaging technologies including computed tomography (CT), magnetic resonance imaging (MRI), micro CT and optical microscopy. Data derived from these technologies, computer models have been reported in published literature [8,[12][13] for simulation of human bone joints, designing implants & scaffolds etc.…”

Scaffolds designed with intricate and controlled interior architecture represent a challenging problem for tissue engineering. Various scaffold-fabricating techniques allow the creation of complex micro-structure but with irregular pore characteristics, resulting in inappropriate & asymmetrical structures not suitable for tissue engineering applications. Computer-Aided Tissue Engineering (CATE) integrates advanced technologies from Biology, Information Science and Engineering for Tissue Engineering applications. In particulars, computer-aided design (CAD), medical image processing, computer-aided manufacturing (CAM), and solid freeform fabrication (SFF) are employed for simulation, design and manufacturing of tissue scaffolds with controlled and regular pore architecture. CATE application to the design and fabrication of scaffolds can guide to improve the biomimetic and biological features of the scaffolds. This paper aims to understand the principles behind various computer aided approaches being utilized for tissue engineering applications particularly cell-scaffold implant modeling, designing and manufacturing.
