| Abstract Scope |
Metal binder jet 3D printing can produce complex geometries with high resolution. However, design limitations in binder jetted structures can make it necessary to split assemblies into multiple parts that will later be joined through sintering or infiltration. This creates a need for precise alignment when joining small parts or parts with fine features, as misalignment can compromise the functionality of the final structure. This study evaluates the alignment accuracy of two stacked plates, the top part measuring 30 mm by 40 mm, supported by four printed alignment features. The alignment features are 1.7 mm diameter cylindrical posts that fit into erodible star-shaped holes. Four samples were printed to assess alignment accuracy and repeatability, providing a basis for evaluating the feasibility of binder jet printing for mechanically joined or assembled small parts. Results showed that alignment was within 0.1 mm of the target position for all measured dimensions. |
