3D Printing Technology

1. Development History

In today’s technological world, a highly regarded revolutionary technology is transforming the way manufacturing and innovation occur at an astonishing pace. This technology is 3D printing. As a digital manufacturing tool, it is sparking a global transformation and showcasing its limitless potential across multiple fields.

3D printing, also known as additive manufacturing technology, is a method of creating solid parts based on three-dimensional CAD data through layer-by-layer material accumulation. The historical development of 3D printing technology is a process of continuous advancement and expansion.

In the 1980s, early 3D printing technology began to emerge. This stage of technology was referred to as rapid prototyping, with the core idea being to print objects layer by layer based on digital models to achieve rapid prototype manufacturing. From the 1990s to the early 21st century, the technology gradually matured, being applied not only in industrial design, model making, and prototype manufacturing but also penetrating fields such as medical, aerospace, automotive, and construction. Entering the 21st century, 3D printing technology achieved even more significant breakthroughs, capable of printing complex structures and precision components, as well as multi-material and multi-color printing. This has made 3D printing applications more extensive and in-depth in manufacturing, medical, aerospace, and other fields.

2. Technology Classification

Various types of 3D printing technologies have been developed, each with different functions. According to ASTM standard F2792, ASTM classifies 3D printing technologies into seven categories, including binder jetting, directed energy deposition, material extrusion, material jetting, powder bed fusion, sheet lamination, and vat polymerization.
