Material Jetting 3D printers provide many advantages like delivering objects with smooth surfaces and excellent resolution up to 0.016 mm. The technology allows users to print with a wide range of materials and colors at a relatively low cost and faster print time.
Material Jetting 3D Printing
Like every other 3D printing technology, the process of material jetting too begins by creating desired object’s design on CAD software. The final design is then cut into several digital images, each one representing a layer of the object with the help of a slicer. Lastly, the STL file is sent to the 3D printer for printing.
The Material Jetting process starts by heating a liquid resin to 30 to 60 degrees Celsius temperature for obtaining an appropriate viscosity for printing.
A print head, like that of an inkjet 3D printer, projects hundreds of micro-droplets of UV light-sensitive photopolymer resin. Later, the resin solidifies to create the first layer of the part. The process is repeated until the printing completes.
Similar to the stereolithography process, material jetting too allows for multi-material and polychrome printing. This is because the printhead hosts multiple nozzles capable of simultaneously jetting different materials and soluble.
- Material jetting 3D printers permit multi-material and multi-color objects.
- The technology is known to produce smooth parts with surfaces comparable to injection molding.
- Objects manufactured by material jetting have homogeneous mechanical and thermal properties.
- Users can easily adjust the properties of the material depending on the outcome they desire.
- Material jetting materials are photosensitive.
- The cost of producing parts with material jetting technology is usually higher.
- Large volumes of parts cannot be printed using this technology.
