Comparative Analysis of 3D Printers, Designing a Custom Printer, and Developing Service Engineering Skills in India

The upsurge in 3D printing has without a doubt redefined manufacturing, prototyping, and designing at a crazy scale in the world, and India cannot be spared from the gains of this technology. The present paper makes a detailed break down of the available 3D printers suitable for commercial and industrial purposes and compares them on the basis of various parameters namely print quality, build volume, speed, material compatibility, and cost. Based on the merits and demerits of some of the well known examples like; Creality Ender 3, Prusa i3 MK3S +, Bamboo Lab X1, ultmacker s5, raise3D pro2, the research seeks to help businesses and individuals as to what printer best suits them. Alongside the comparison of the existing models of 3D printers, this paper looks into the design and construction of a 3D printer that would be designed specifically to suit certain applications. The discourse reviews the criteria for choosing the various components, on structural design, motion systems, extruders, control boards and also the expected costs on building a functional prototype. Given the nature of projects which a custom built 3D printer can deal with, it can be economical as well as efficient. In addition, with the increasing use of 3D printing by various sectors within India, the need for service engineers who can install, maintain and fix these machines has increased tremendously. This paper describes a training program designed for service engineers in India. It includes details on general engineering principles, practical and field training, trouble shooting, and client interactions. The goal of this effort is to prepare a workforce which will be able to sustain the burgeoning 3D printing ecosystem in India and achieve the desired productivity and reliability
