Comparison with Other Additive Manufacturing Technologies

When it comes to additive manufacturing, there are several different technologies available, each with its own strengths and weaknesses. This section compares Material Jetting with other main additive manufacturing technologies. These technologies include Fused Deposition Modeling (FDM), Selective Laser Melting (SLM), and Digital Light Processing (DLP).

The deposition of melted thermoplastic filaments extruded through a heated nozzle involves FDM technology. Compared to Material Jetting, FDM is generally faster and more cost-effective, but it has lower resolution and accuracy. Additionally, FDM parts are often less smooth and require more post-processing to achieve a finished look.

SLM technology uses a laser to melt and fuse metallic powders layer by layer to create parts. Industries commonly use this technology in aerospace and medical applications where high strength and precision are critical. However, Material Jetting is faster and less expensive than SLM, and it can work with a wider range of materials beyond just metallic materials.

DLP technology uses a light projector to cure liquid resin layer by layer, creating parts with high resolution and accuracy. Like Material Jetting, DLP is capable of producing intricate geometries with exceptional detail. However, DLP parts can be brittle and have lower mechanical strength compared to Material Jetting parts. Each additive manufacturing technology has its own advantages and disadvantages. The best choice depends on the project’s specific requirements. Material Jetting is ideal for complex geometries with high accuracy and resolution. It’s useful in industries like dentistry, jewelry, and art.

Working Principle of Material Jetting

Material Jetting is an additive manufacturing process that uses drop-on-demand (DOD) technology to create parts layer by layer. The working principle of Material Jetting involves the deposition of tiny droplets of photopolymer material from an inkjet printhead. This printhead moves back and forth over the build area, selectively depositing droplets of material onto the build platform.

The inkjet printhead is a critical component of the Material Jetting process. It contains an array of nozzles, each of which can be independently controlled to eject droplets of material. The printhead is capable of depositing material with a resolution as fine as 16 microns, making it ideal for creating highly detailed parts with complex geometries.

The DOD technology used in Material Jetting allows for precise control over the size and placement of each droplet of material. The material droplets are deposited in a highly controlled manner, which ensures that each layer is accurate and uniform. This level of precision allows Material Jetting to produce parts with exceptional surface quality and dimensional accuracy.

Material Jetting is an additive manufacturing technology. It can create complex geometries with accuracy. DOD technology and inkjet printhead make it precise. Material Jetting is popular in many industries. It can create functional prototypes and custom parts.

Drop on Demand (DOD) Technology

DOD technology uses precise droplet ejection to create 3D prints. It creates pressure pulses to force liquid material out of the nozzle. The DOD technology deposits the droplets layer by layer to create the object. A wider range of materials can be used with DOD technology. It can handle viscous or solid materials that it can melt and extrude. DOD technology has a reputation for its high precision and accuracy. It’s ideal for producing intricate and complex geometries with fine details.

Inkjet Printhead

Inkjet Printhead technology uses droplets of liquid material to create 3D objects. The printhead dispenses small droplets of material onto a build platform. The material is then solidified to create the final object. This process is precise and allows for high-resolution prints.

Materials Used in Material Jetting

Material jetting technology can use a wide range of materials, including photopolymers, thermoplastics, and metals. Material jetting uses photopolymers that cure when exposed to light. Commonly used thermoplastics include ABS and nylon. Although expensive, metals like silver, gold, and platinum can also be used. Researchers are exploring ceramics and composites as potential material jetting materials. Material jetting technology’s versatility enables the use of various materials for different applications.

Photopolymers

Photopolymers are a common material used in material jetting. They are liquid polymers that solidify when exposed to UV light. They can produce high-resolution parts with fine details and smooth surfaces. Photopolymers come in various colors and can also be translucent or transparent. Some common applications include prototyping, product design, and jewelry making. The material has its drawbacks as well, such as being brittle and susceptible to UV degradation over time.

Thermoplastics

When heated, thermoplastics liquefy, and when cooled, they solidify. Material jetting technology frequently uses them because they can be melted and reformed repeatedly without undergoing any chemical changes. The thermoplastics ABS, PET, nylon, and polycarbonate are a few examples of those utilized in material jetting. These materials are ideal for a variety of applications, including prototyping, product design, and even medical and dental applications because of their great strength, durability, and chemical resistance. The tendency for thermoplastics to distort during the printing process and their relatively low heat tolerance in comparison to other materials are some drawbacks of thermoplastics in material jetting.

Other Materials

Material jetting can use not only photopolymers and thermoplastics, but also metals, ceramics, and composites. The binder mixes with these materials to make them printable and transforms them into a paste-like substance that the printhead can jet. This process allows for the creation of complex parts with different material properties. However, processing these materials can be costlier and more complex compared to photopolymers and thermoplastics.
