Summary
Mechanical adaptation and stability of implants are dependent on strain energy density algorithms of their surfaces. These applications are in their early stage, but theoretical predictions show us that we can manufacture very strong, flexible biomaterial surface which has a shock absorbing ability. Laser micro-machining is a clean tool for biomedical industry. The purpose of this manuscript is to consolidate a laser micro-machining method for imitating lotus effect on commercially pure titanium specimen surfaces and to develop a novel strain energy density algorithm. Novel 3D nelumbo leafs were prepared using a fiber laser (lambda=1060 nm) with 200-250 ns pulse durations and optimum operation parameters were suggested. (C) 2015 Elsevier Ltd. All rights reserved.
