Polyjet printing is a 3D printing process that uses a liquid photopolymer resin that is cured by a UV light to create a 3D object. The resin is jetted onto a build platform in layers, and each layer is cured by the UV light as it is deposited. The process can produce parts with high accuracy and resolution, and can also produce multi-material parts by jetting different materials simultaneously. Polyjet printing is often used for creating prototypes, molds, and functional parts with a high level of detail and realism.

Applications

1. Product design: creation of highly detailed and realistic prototypes for product design and development
2. Medical: production of surgical guides, anatomical models, and prosthetics
3. Architecture: creation of architectural models and scaled models
4. Jewelry: creation of intricate and detailed jewelry designs
5. Consumer goods: production of custom phone cases and accessories, toys, and household items
6. Art and design: creation of 3D art pieces, sculptures, and installations.

Advantages

1. High accuracy and resolution, enabling the creation of intricate and detailed parts
2. Capable of producing multi-material parts with different colors, textures, and hardness levels
3. Wide range of materials to choose from, including flexible, rigid, and transparent resins
4. Smooth surface finish, reducing the need for post-processing
5. Fast printing speeds compared to some other 3D printing technologies

Disadvantages

1. Limited build volume
2. Higher cost compared to some other 3D printing technologies
3. Resins used can be expensive and require proper handling and storage
4. Parts may require additional curing or post-processing before they are ready for use
5. Multi-material parts can be difficult to design and optimize, and can increase the complexity of the printing process.
