Technology
Digital Light Processing (DLP) is a 3D printing process that uses a vat of liquid photopolymer resin that is cured by a light projector layer by layer to create a 3D object. The light projector displays an image of each layer onto the surface of the resin, causing it to solidify and bond to the previous layer. DLP is known for its high resolution and speed, making it a popular choice for creating detailed parts quickly.
Applications
Prototyping: rapid prototyping of small, detailed parts
Engineering: creation of functional prototypes for mechanical and electrical engineering applications
Jewelry: creation of high-detail and intricate jewelry designs
Dental: production of dental models, molds, and aligners
Medical: production of custom prosthetics, surgical guides, and anatomical models
Education: creation of detailed models and teaching aids for use in schools and universities.
Advantages
High accuracy and resolution, enabling the creation of intricate and detailed parts
Faster printing speeds compared to some other 3D printing technologies
Wide range of materials to choose from, including biocompatible and flexible resins
Smooth surface finish, reducing the need for post-processing
Capable of producing parts with fine details and smooth curves
Disadvantages
Limited build size, restricting the size of parts that can be produced
Higher cost compared to a few other 3D printing technologies
Resins used can be expensive and require proper handling and storage
Parts may require additional curing or post-processing before they are ready for use
The resin used in DLP printing can be toxic and require careful handling and disposal.
