About the Special Issue

The 3D printing of biometals using commercial technologies like powder bed fusion, direct metal laser sintering, direct energy deposition, selective laser melting, etc. has been widely reported in the past decade for clinical and biomedical applications. However, these biometals have serious problems related to stress shielding when being used for implant or prosthetic applications. This special issue has been planned to address stress-shielding-related issues through innovative, novel implant/ prosthetic designs/meta-structures covering orthopedic and dental applications. This special issue invites experimental, analysis, and review articles focussing on solutions related to metal 3D printing of biometals with tunable stress shielding capabilities. Along with the design/ topographic optimization use of novel, hybrid materials is of interest in this special issue (covering both human and veterinary applications). The multi-material 3D printing covering more than one metallic alloy for reducing the stress shielding, digital twinning of developed 3D printed implants is also of interest in this special issue.

Keywords: metal 3D printing; digital twinning; meta-structures; multi-material; stress shielding; dental applications; orthopedic implants; prosthesis

Bio-materials for intramedullary pin application in canine femur: a comparative analysis

Aim:

In this study, the finite elements analysis (FEA) was performed on an intramedullary (IM) pin to be used in the canine femur. The 03 different biomaterials [17-4-precipitated hardened (PH)-stainless steel (SS), nickel alloys (Ni)-625, titanium alloys (Ti)-6Al-4V] were selected for comparative FEA. In-vitro analysis was also performed in simulated body fluid (SBF) on selected biomaterials for possible application in the canine femur.

Methods:

FEA was performed on 03 different biomaterials (17-4-PH-SS, Ni-625, and Ti-6Al-4V) based on Von-Mises criteria (at an applied load of 1,500 N, cell type: tetrahedron, grit size: 0.15 mm, number of nodes: 213,989 and elements: 145,012). The distal end of the IM pin was fixed, and the load was applied to the proximal end. In-vitro analysis was performed (on a potentiostat setup) to establish the corrosion rate of various biomaterials (17-4-PH-SS, Ni-625, and Ti-6Al-4V).

Results:

The results of FEA show Ni-625 absorbed the maximum Von-Mises stress in the case of tensile and compression loading (104.12 MPa). In the case of torsion loading, the maximum Von-Mises stress was absorbed by 17-4-PH-SS (63.331 MPa). The maximum Von-Mises elastic strain (0.00093473) was observed for Ti-6Al-4V while tensile and compression and minimum deformation (0.013869 mm) in tensile loading.

Conclusions:

Based on this study, the maximum safety factor against failure (N) [ratio of 0.2% of yield strength (σ_y) to the Von-Mises stress (σ_v)] was observed as 10.75, 11.38, and 15.89, respectively, for tensile, compression, and torsional loading in the case of Ti-6Al-4V. Also, the better biocompatible material for the orthopaedic implant application based on the corrosion result is Ti-6Al-4V due to a lower corrosion rate (2.63211 × 10^–10 mm/year) in comparison to 17-4-PH-SS and Ni-625. Overall, the Ti-6Al-4V is a better material than 17-4-PH-SS and Ni-625 for the intended application.
