“…We used SEM, a confocal laser scanner (TopScan 3D) and an atomic force microscope (AFM) to characterize the different ceramic surfaces. TopScan 3D has previously been described [36], and proven to be an appropriate method for topographical characterization of biomaterials [37]. The best possible resolution in horizontal axes (X and Y) is 0.5 mm and in height (Z) axis is 6 nm.…”

“…The 3D parameter [8] values for two of the surfaces an original in vivo and a replica measurement are given in Figure 3 shows "large area measurements" taken on both the "real" and replica surfaces. Specific features were then zoomed for higher scale analysis of the two data sets, figure 3(c) and (d).…”

On in-vivo skin topography metrology and replication techniques. Abstract. Human skin metrology is an area of growing interest for many disciplines both in research and for commercial purposes. Changes in the skin topography are an early stage diagnosis tool not only for diseases but also give indication of the response to medical and cosmetic treatment. This paper focuses on the evaluation of in vivo and in vitro methodologies for accurate measurements of skin and outlines the quantitative characterisation of the skin topography. The study shows the applicability of in-vivo skin topography characterisation and also the advantages and limitations compared to conventional replication techniques. Finally, aspects of stripe projection methodology and 3D characterisation are discussed as a background to the proposed methodology in this paper. Journal of Physics

A Novel Manufacturing Route for Fabrication of Topologically‐Ordered Porous Magnesium Scaffolds

The use of porous metal foams as biomaterial scaffolds has been widely adopted; however, many of these porous structures are manufactured with pore architectures that are inherently random. This makes structural optimization for a specific purpose challenging. Scaffolds containing ordered pore architectures can be fabricated to meet design criteria, such as porosity, stiffness, and volume fraction. Mg and its alloys offer potential as a new class of degradable metallic orthopedic biomaterials. In comparison with current metallic orthopedic implant materials, Mg offers advantages such as, closer‐to‐bone stiffness and biodegradability, thereby eliminating the need for a second surgery to remove hardware. Currently there are few methods described in literature to manufacture ordered porous Mg. The aim of this study was to determine the resolution of a novel indirect solid free‐form fabrication (SFF) process for producing topologically ordered Mg (TOPM) structures. The multi‐step method involved the printing of an SFF mould, NaCl infiltration, and liquid Mg casting techniques. Using a range of characterization methods, we demonstrated that the selected structures were manufactured with a high level of accuracy. Differences in dimensions from CAD models to Mg scaffolds ranged from 2.5% to a maximum of 8.33%. Similarly, there was a maximum of 6.1% reduction in porosity in Mg scaffolds compared with initial design. Meanwhile, with surface roughness of 10.17 ± 1.75 µm, there was an average of 70% increase in surface area. This study demonstrates a simple, reliable, and safe route to manufacture TOPM scaffolds for potential application in medical device design.
