| Abstract | Recent developments in microfluidics have opened up new interest in rapid prototyping with features on the microscale. Microfluidic devices are traditionally fabricated using photolithography, however this process can be time consuming and challenging. Laser ablation has emerged as the preferred solution for rapid prototyping of these devices. This paper explores the state of rapid prototyping for microfluidic devices by comparing laser ablation to micromilling and 3D printing. A microfluidic sample part was fabricated using these three methods. Accuracy of the features and surface roughness were measured using a surface profilometer, scanning electron microscope, and optical microscope. Micromilling was found to produce the most accurate features and best surface finish down to ∼100 μm, however it did not achieve the small feature sizes produced by laser ablation. 3D printed parts, though easily manufactured, were inadequate for most microfluidics applications. While laser ablation created somewhat rough and erratic channels, the process was within typical dimensions for microfluidic channels and should remain the default for microfluidic rapid prototyping. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
