The Department of Mechanical Engineering, of Srinivas Institute o Technology, ASMA in association with Entrepreneurship Development Programme Cell (EDP) organized a workshop called"Layer by Layer" to introduce students to the emerging field of additive manufacturing and its industrial applications. Mr. Chetan, a sixth-semester Mechanical Engineering student was the resource person for this event, whose practical knowledge and enthusiasm made the session highly engaging and informative. The event aimed to provide participants with a comprehensive understanding of 3D printing technology, its working principles, and its growing significance in modern manufacturing.

The workshop commenced with an introductory session highlighting the evolution of manufacturing processes, from conventional subtractive methods to advanced additive manufacturing techniques. The resource person explained the fundamental concept of 3D printing, emphasizing how three-dimensional objects are created by depositing material layer by layer based on digital design files. Participants were introduced to the history, development, and various applications of 3D printing across industries such as healthcare, aerospace, automotive, construction, and consumer products.

During the technical session, Mr. Chetan elaborated on the complete workflow involved in 3D printing. He explained the process of creating computer-aided design (CAD) models, converting them into STL files, slicing the models using specialized software, and generating machine instructions for the printer. The participants gained insights into different 3D printing technologies, including Fused Deposition Modeling (FDM), Stereolithography (SLA), and Selective Laser Sintering (SLS). The discussion also covered commonly used printing materials such as PLA, ABS, resin, and nylon, along with their characteristics and applications.

A live demonstration formed the highlight of the workshop. Participants observed the operation of a 3D printer in real time and learned about machine components such as the extruder, print bed, nozzle, filament spool, and control interface. The resource person explained essential printing parameters, including layer height, print speed, infill density, and support structures, illustrating how these factors influence print quality and production time.

The workshop was successfully conducted under the guidance of Prof. Sathyaprakash, EDP Cell department coordinator, Dr. Shankar K.S., Head of the Department of Mechanical Engineering, and Dr. Shrinivasa Mayya D, Principal, encouraged and motivated the students to actively participate and make the most of this learning opportunity.
