Some common materials used in DED include titanium, aluminum, steel, and nickel alloys. The choice of material depends on the specific application and the desired material properties of the final part.
Binder jetting
Binder jetting is a 3D printing process that involves the use of a powder bed and a liquid binder. The process is also known as powder bed and inkjet 3D printing or drop-on-powder 3D printing.
In binder jetting, a thin layer of powder material, such as metal, ceramic or plastic, is spread over a build platform. A liquid binder is then selectively deposited onto the powder layer using an inkjet printhead. The binder acts as an adhesive, binding the particles together where it is applied.
After a layer has been printed, the build platform is lowered, and a new layer of powder is spread over the previous layer. The process is repeated, layer by layer, until the object is complete. Once the printing is finished, the part is then cured, sintered, or infiltrated to strengthen the bonds between the particles.
Binder jetting is commonly used for rapid prototyping, small-batch production, and in the manufacturing of complex geometries, such as lattice structures. It offers several advantages over other 3D printing techniques, including high-speed printing, low cost, and the ability to print a wide range of materials.

- Machining: In some cases, additional machining may be required to achieve the desired shape or dimensions of the object. This can be done using traditional machining methods such as milling or turning.
- Surface finishing: Depending on the intended use of the object, additional surface finishing may be required. This can include painting, plating, or coating the object with a protective layer.
It’s important to note that the specific post-processing requirements for a 3D printed metal object will depend on the material used, the design of the object, and the intended use. While post-processing can add time and cost to the production process, it’s often necessary to achieve the desired finish or properties for the object.
Limited size of printed parts
One of the main factors that limits the size of parts that can be 3D printed in metal is the size of the 3D printer itself. Metal 3D printers can be quite large, but they still have limits on the size of the objects they can print. For example, some printers may only be able to print objects that are a few inches in size, while others may be able to print objects that are several feet in size.
Another factor that can limit the size of 3D printed metal parts is the cost of the printer and materials. As the size of the part increases, so does the amount of material and time required to print it. This can make the process more expensive and time-consuming, which can be a limiting factor for some users.
Finally, the design of the part can also be a limiting factor for the size of 3D printed metal parts. Some designs may require intricate internal structures or complex shapes that are difficult or impossible to print at a large scale.
Despite these limitations, 3D printing metal still offers many benefits for creating metal parts with precision and accuracy. As the technology continues to evolve and improve, it’s likely that the size limitations will become less of a barrier for those interested in using 3D printing metal to create larger parts.
