Metal binder jetting is a 3D printing technology used to produce complex metal parts with excellent mechanical properties.
Compared with other metal processing technologies, producing metal parts using binder jetting is significantly more cost-effective, with costs often only a fraction of traditional methods, and it places very few restrictions on design. Binder jetting equipment also features a large build volume and high production speed, making it well-suited for rapid delivery of small to medium batch parts. Its combination of speed and cost efficiency makes it an ideal choice for industries that require high-strength components, such as industrial manufacturing, automotive, consumer goods, and oil and gas.
| Features | Description |
|---|---|
| Build Size | 15 inches × 10 inches × 10 inches (400 mm × 250 mm × 250 mm) |
| General Tolerance | Depending on the size and geometry of the part, the part may have a shrinkage rate of 0.8%–2.5% during cooling. The shrinkage rate of internal geometries (such as slots and holes) can be as high as 5% |
| Layer Height | 0.004 inches (100 microns) |
| Surface Roughness | 30 to 200 microns Ra (arithmetic mean deviation), depending on the build direction, surface finishing method, and the material used for building |
| Density | Uniform material with a density of over 98% |
This table shows the general tolerance range of the metal binder jetting technology. Stresses generated during the building process and other geometric factors may cause deviations in tolerance and flatness. Parts with thicker geometries, flat or wide structures, and uneven wall thickness are more likely to have significant deviations or warpage. After the successful completion of prototype building, higher precision tolerances may be achieved through manual quotation review, but it needs to be approved on a case-by-case basis depending on specific circumstances. Unless otherwise specified, general tolerances apply to parts before secondary finishing or post-processing. For more information on process tolerances, please refer to EPTAHUB's manufacturing standards.

Metal binder jetting is an additive manufacturing metal printing technology that builds metal parts from CAD files through a multi-step process. First, the binder jetting equipment uses a binder to fuse the metal powder layers together. After the part is bonded, the formed shape is called a green part, which is then cured. The cured green part is placed in a furnace for sintering or bronze infiltration.
Since all sides of the binder jetted part are supported by unused powder, this reduces or even eliminates the need for post-processing. However, most binder jetted parts need to be processed in a furnace, so the parts are prone to shrinkage, slight porosity, and fine features may not be retained. Engineers should follow design-for-manufacturing principles when designing binder jetted parts.

The stainless steel 3D parts we print using metal binder jetting technology undergo a standard “zirconium sandblasting” surface treatment. This zirconia-based ceramic bead blasting process lightly peens the part surface without significantly altering fine features or dimensions. The treated part surface presents a uniform matte light gray color with a slight satin texture.
