Material Jetting 3D printing is a groundbreaking technology based on the fundamentals of 3D printing. This process utilizes inkjet technology to produce highly accurate three-dimensional models with much higher precision results than those generated by traditional 3D printing machines. In this process, layers of material are deposited drop by drop in areas determined beforehand, allowing for high resolution. The use of droplets also allows for complex geometrical features to be built, such as parts and tools, which can be used across various industries ranging from automotive design to medical applications.
Process of Material Jetting
- The process begins with preparing the build chamber, which is usually enclosed to maintain a controlled environment.
- The material used in the process, such as thermoplastic or photopolymer resin, is loaded into a reservoir or cartridge and heated to its melting or curing point.
- The material is then jetted through an array of nozzles or a single nozzle, similar to an inkjet printer, and deposited onto the build platform. The nozzles move back and forth, depositing the material layer by layer.
- For photopolymer resins, a UV light source is used to cure the material layer by layer. The curing process is carefully controlled to ensure the correct amount of curing occurs.
- Once each layer is deposited and cured, it cools and solidifies, bonding with the layer below it.
- The process repeats until the entire part is complete. Multiple materials and colours can be jetted simultaneously, allowing for the creation of complex parts.
Benefits of Material Jetting
The key benefit of material jetting 3D printing is the high precision achieved during the production process. Compared to conventional 3D printing techniques, it offers much higher and more reliable accuracy. By using droplets instead of extrusion, complex geometrical features can be built with much greater detail.
Another advantage of material jetting 3D printing is its cost effectiveness compared to traditional methods. This process requires less time and fewer materials than conventional manufacturing techniques, making it a cost-effective option for many applications.
The versatility of this technology means that the same machine can produce various objects in different geometric shapes and sizes with a high degree of accuracy. This makes it ideal for use across various industries, such as automotive design, medical applications, Mining, railway and industrial product prototyping.
Yet another benefit associated with material jetting 3D printing is its ability to save time in the production process compared to traditional methods. By using a single machine for multiple processes, projects can be completed in a much shorter time than if each step was done separately by hand or other machines.
Finally, one great advantage of this type of 3D printing is its environmental friendliness due to the minimal waste produced during the production process. By using recyclable materials and producing products without excess metal or plastic parts that would otherwise need to be disposed of, this technology works towards creating an eco-friendly manufacturing environment.
