Material jetting can be described as a 3-D printing technique that creates layers of components by jetting material droplets onto a building platform. The droplets are usually around the size of human hair and are then deposited on the platform using several print heads.
The materials are then cured or solidified by a variety of methods, including the use of UV light or heat according to the type of material that is used. Material Jetting is an incredibly versatile technology that produces parts that have a high level of precision and accuracy which makes it perfect for prototyping as well as smaller production runs.
What is the meaning of Material jetting?
Material jetting is a 3D printing technique that involves the jetting and curing of small droplets of photopolymer material layer by layer to make 3D objects. The process involves printing heads with tiny nozzles that jet the materials onto a building platform. After that, the droplets are then cured by UV light. Material jetting is extremely precise and can create intricate geometries with fine detail which makes it extremely popular in industries like jewelry, dentistry, and the design of products.
However, the costs of the materials and equipment could be more expensive than other 3D printing methods, and the process could be slow. Despite its limitations, it offers the capability to print using various types of materials, such as resins, acrylics, and epoxies and it can print multiple materials simultaneously and allow for the making of multiple-material items.
How Material Jetting Works
Here are the steps that are involved in material jetting:
» Create digital 3D models: The initial step of material jetting is to make an electronic 3D image of your object that you intend to print using computer-aided design (CAD) software. This model acts as a guideline for the material jetting procedure.
» Cut models into layers: After you have the 3D model is constructed then it is cut into thin cross-sectional layers with special software. Each layer acts as a reference to the process of material jetting and serves to create the final model.
» Inject the photopolymer material: Next step involves loading the material into a printing head that has tiny nozzles. The material is usually in liquid form and stored in a reservoir or cartridge which is attached to the printer.
» Jet the material: Once the material is loaded with the 3D model is cut into layers and then printed, the process of printing can begin. The printer jets tiny droplets of material on the build foundation, using the layer-by-layer instructions given in the model.
» Cure the material: after each layer has been dropped onto the platform for building and the material is then cured to make it more solid and allow it to grow layer by layer. This is usually accomplished using UV light that is directed at the platform for the purpose of curing the material and forming a solid layer.
» Repeat the process: until the layer has been cured then the platform for the building is slightly lowered to allow room to accommodate the subsequent layer and the process repeats. The printer jets additional material onto the platform, then the radiation cures it by building the object layer.
» Finish the object: After all layers have been printed and dried the final object is finished. The object might require some final touches including the removal of the supports, or roughing out edges. however, it’s in good condition for use.
In general, material jetting is a very precise 3D printing process that can create precise objects with intricate geometries. But, it could also be a lengthy and costly procedure when compared with other 3D printing methods.
Materials Used in Material Jetting
Material Jetting is able to use various materials, including photopolymers thermoplastics, and metals. Photopolymers are the most widely used materials for Material Jetting. It is a type of liquid resin which are made to cure with UV light. Thermoplastics are solid substances that are then melted and jetted onto the building platform. Metals are also utilized for Material Jetting, but the process requires a laser with high power in order to heat the particles of metal before transferring them onto the building platform.
