Promoting Technology-Enhanced Project-Based Learning through Application of 3D Printing Technology for Mechanical Engineering Education

Abstract

3D printing is a progressively developing technology under umbrella of industrial revolution 4.0 for rapid prototyping and end-use applications. 3D printing technology is nowadays used in all sectors including automotive, civil, agriculture, medical, aerospace, art and jewelry, and education too. In this work, 3D printing technology is employed as a technology-enhanced tool in engineering education in combination with project-based learning for third-year undergraduates. The combined technology-enhanced project-based learning strategy was used to 3D print components of internal combustion engines to enhance students' comprehension of the fundamentals of internal combustion engines. The activity resulted in improvement in the performance of students in the examination (5.15% improvement in CO attainment and more than 10% improvement in all modes of written examination) as well as professional skill development promoting multidisciplinary learning opportunities and lifelong learning. Keywords—3D printing; engineering education; IR4.0; project-based learning; technology-enhanced active learning. JEET Category—Choose one: Research, Practice, or Op-Ed.

Fused filament fabrication in CAD education: A closed-loop approach

“…3D printing is essential in Mechanical Engineering Education, as it enables students to prototype and manufacture complex components, fostering practical skills, design optimization, and innovation in the field. The work by Powar and Patil explores the integration of 3D printing technology and projectbased learning in engineering education to enhance students' understanding of internal combustion engines, resulting in improved examination performance and the development of professional skills, fostering multidisciplinary learning opportunities and lifelong learning [21]. The study by Solikin et al focuses on developing portable and lightweight learning media using 3D printing technology with Polylactic Acid as the base material, specifically targeting Light Vehicle Engineering Vocational School students to support online learning during the Covid-19 pandemic to explain the competency of a 2-stroke engine in a distance learning setting [22].…”
