However, parts tend to have only moderate mechanical properties and a high porosity, meaning that they may not be suitable for all requirements. Binder jetting offers unique material options compared to high-energy deposition alternatives. This agent acts as an adhesive to bind the powders together before more powder is added on top and bound to build up a part layer-by-layer. For example, a metal part might need to be sintered with a low-melting-temperature metal like bronze. In addition, coloured binders can be used to create full colour parts or prototypes. WebBinder Jetting Advantages and Disadvantages As mentioned above, Binder Jetting is faster and more cost-effective than many 3D printing technologies. WebThe Metal Binder Jetting is an emerging technology with distinct advantages that make it a process for the future. These green parts do not possess final part strength and are Parts that have just been created using binder jetting are in a green state and typically have high porosity and poor mechanical properties. Some binder jetting printers have secondary nozzles for pigments/dyes, allowing for a full range of color printing like traditional 2D inkjet printers. Binder Jetting is usually cost effective because its both low energy and uses affordable materials. To create functional, strong metal parts, a secondary process is recommended. When expanded it provides a list of search options that will switch the search inputs to match the current selection. It uses less energy as a laser is not required, and produces parts quickly, resulting in a lower operating cost per part. This reduces the sintering time and can now be achieved using modern, sustainable debinding fluids. XJets Nano Particle Jetting (NPJ) 3D printing is similar, but is not considered Binder Jetting. During the binder jetting process, a binding agent is selectively deposited onto a powder bed, bonding the areas together to form a solid part, one layer at a time. Thomas Register and Outside of industrial applications, binder jetting type processes have even found their way into baking, with businesses like The Sugar Lab using 3D printing with granules of sugar and water to create complex culinary structures.
