Multiobjective optimization of Nd:YAG direct laser writing of microchannels for microfluidic applications

摘要: After entering the twenty-first century, there has been an ongoing drift toward miniaturization of discrete products in several areas. One such application is microfluidic device used biomedical applications. The challenge with manufacturing devices/biochips that they often make use broad range materials within a single chip, making it difficult to manufacture these devices conventional photolithographic-based techniques. Laser processing proved be important tool for development because accuracy, flexibility, and most one material independence offers. In this work, laser direct writing technique fabrication microfeatures AISI 1045 steel basic purpose research work assess performance machining channels by investigating effects different process parameters using design experiments (DOE) regression modeling analysis. model developed Optimal Design IV Response surface methodology taking five input including scan strategy which mostly overlooked past research. Analysis variance (ANOVA) carried out measures namely width error rectangular section, semicircular taper degree, recast layer, removal rate. Multiobjective optimization variables out, shown optimized solutions are obtained at moderate frequencies, high speed, minimum layer thickness.
