A review of recent trends and challenges in 3D printing

The recent developments in 3D printing also known as “Additive Manufacturing” or AM have revolutionized the modern manufacturing process and the engineering design process. Emerging use of 3D printing technology is prevalent in automotive, manufacturing, aerospace, pharmaceutical industry & healthcare, fashion, retail and sports. In this paper, the author propose to review the recent trends and challenges in 3D printing technology. The technological advancements in extrusion materials, design & processes, equipment's capability have brought down the cost of manufacturing. The proposed paper will review latest developments in 3D printing material types, manufacturing techniques, equipment types, and the development of standards for selecting material, quality control, and 3D printing machinery. World demand for 3D printers and related materials and software is projected to rise 21 percent per year to $5.0 billion in 2017 per freedoniagroup. It is about time to educate the future designers, engineers and entrepreneurs on 3D printing. A typical course curriculum is also proposed to add an elective course in the mechanical engineering department in one of the Michigan regional universities.
