Chapter 1: Techniques

How Polyjet 3D Printing Works

Polyjet 3D printing, also known as Polyjet technology, employs a technique called stereolithography (SLA). In this process, a liquid photopolymer resin is cured layer by layer using ultraviolet (UV) light. The UV light selectively solidifies the resin, creating a solid, three-dimensional object.

Key Features of Polyjet Technology:

• Layer-by-Layer Construction: The process involves depositing thin layers of resin, which then solidify upon exposure to UV light. This allows for the creation of complex geometries and intricate details.
• Multiple Material Support: Polyjet technology can handle a wide range of photopolymer materials, including rigid, flexible, and transparent options. This enables the fabrication of objects with diverse properties and functionalities.
• High Resolution and Accuracy: The use of UV light for curing results in excellent surface finish and dimensional accuracy.
• Rapid Prototyping: The technology allows for quick design iterations and production of prototypes, significantly accelerating development cycles.
