Previously we mentioned that 3D printing can be divided into 7 categories, including material extrusion, binder jetting, powder bed fusion, material jetting, sheet lamination, directed energy deposition, and stereolithography. Below we will introduce these 7 categories in details.

In recent years, 3D printing technology has developed rapidly and has gradually become an indispensable part of modern manufacturing. According to the latest data from the "2024 3D Printing Trend Report" by Protolabs, the global 3D printing market size reached US$22.14 billion in 2023 and is expected to grow to US$57.1 billion by 2028.
