What is Material Jetting 3D Printing?
Material jetting is a 3D Printing process that involves jetting photosensitive resin from an inkjet head, then curing it upon deposition with UV light. An outstanding process for high-accuracy prints, especially those requiring parts with multiple materials or variable material characteristics across a part.
What are the Different Types of Material Jetting?
- Material Jetting (Resin, Cartridge)
- Vat Photopolymerization (Resin, UV Laser)
- Material Jetting (Ink)
- Material Jetting (Wax, Cartridge)
- Material Jetting (Metal, Cartridge)
What are the Advantages of Material Jetting?
- Multi-Material Parts. Multiple materials can be used in a single part allowing for different properties within the part.
- Material Selection. Choose from more than 30 distinct, different materials to meet the needs of your part. In some cases, you blend materials to mix properties and color.
- Short Lead Times. Get your parts quickly and shorten the gap from concept to finished part.
- Highly Accurate. MJP and Polyjet can print in layer thicknesses as low as 16 microns and typically resolve detailed features as small as 0.001″ (0.025 mm).
- Smooth Stock Finish. High-detail accuracy allows for surface finish down to 80 µin Ra with little to no post-processing.
What are the Limitations of Material Jetting?
- Low Durability. To successfully be jetted from an ink head, fairly low viscosity—and thus, typically less durable—materials are also required. Further, as a general rule, photopolymers weaken over time, especially when exposed to light.
- Downward-facing surfaces. Support structures required, the removal of which can impact surface finish and post-processing speed connex, polyjet, multi-material printing, multi-material 3D Printing.
