Table 1 shows these techniques, the 3D printing process, materials, advantages, and disadvantages. For example, with a simple sandblasting step it is possible to achieve a surface finish of 2 m Ra. The binder acts as an adhesive between powder layers. At this point, the part is approximately 60% porous. Since binder jetting 3D printing machines often have secondary printheads that add color as the primary printhead adds the binding agent, its easy to create full-color models using sandstone or polymethyl methacrylate (PMMA) powders. However, material jetting involves the depositing of droplets of photosensitive resin that are then hardened with an ultraviolet light, while binder jetting deposits layers of powdered materials that are bound together with a binding agent. These large machines are generally used to produce sand casting molds. and machining can be an optimal solution. Limited material use of photo-resins. Full colour models typically use a 100 micron layer height while metal parts use a layer height of just 50 microns. Infiltration produces slightly less dense parts than sintering, but sintering can cause unwanted and unpredictable part shrinkage. There are two main types of materials used with Binder Jetting, sandstone and metals. Sintering: After printing is complete, the parts are placed in a high temperature furnace, where the binder is burnt out and the remaining metal particles are sintered (bonded) together, resulting in parts with very low porosity. Other questions about EWIs AM capabilities and services? However, every solution has its pros and cons. To create functional, strong metal parts, a secondary process is recommended.
