Purpose: The purpose of the paper is to describe exploring laser-guided metal deposition through a microbe metabolite. Design/methodology/approach: A maskless micro-fabrication of laser-guided deposition process through the metabolite of Acidophilic bacteria Thiobacillus ferrooxidans (T.f.) is explored. Findings: The authors have conducted an analysis of the metal deposition process using the point thermal-source of the Nd:YAG laser through the metabolite of Acidophilic bacteria Thiobacillus. An analytical model adopting the moving point heat source on the substrate and heat transfer conditions is presented. The thermal field generated by the laser input energy is investigated. Practical implications: Though the mechanism of the laser-assisted deposition process is not fully revealed by biologist yet, the current model provides a means of control of the line deposition of metals. Originality/value: Based on the fundamental knowledge of how the line width varies with laser power and scanning speed, more investigation of the mini-scale heat convection and the threshold temperature of chemical reaction is expected in the future for further understanding of this novel metal deposition method triggered and written by laser.
