133.10.3 - Fixturing & Workflows

Advanced Process Fixturing

With Additive Manufacturing ("AM", aka "3D-Printing") the need for fixturing might initially seem less critical because objects are built layer by layer, but fixturing still plays a crucial role in many AM processes.
The importance of Fixturing for AM can be summarize by the following considerations:
- Support for Complex Structures: AM allows for the creation of complex, intricate designs that might not be self-supporting during the printing process. Fixtures can provide the necessary support to these structures.
- Accuracy and Precision: Proper fixturing ensures that the build material is deposited precisely, maintaining the dimensional accuracy of the printed object.
- Reduction of Material Deformation: During the printing process, materials can warp or distort due to thermal stresses. Fixtures help in minimizing these deformations.
- Post-Processing Support: Many AM processes require post-processing steps like heat treatment or surface finishing. Fixtures are important for holding the part securely during these processes.
- Repeatability and Mass Production: For additive manufacturing to be viable for mass production, repeatability and consistency are key. Fixturing helps in maintaining these standards across multiple print cycles.

Hybrid Manufacturing is the combination of two or more different manufactuing processes. Most commonly this is contextualize with Additive-Subtractive Hybrid Manufacturing (+/-), but other processes can be included as well.
Fixturing for hybrid manufacturing is a critical component in the efficient and effective integration of additive and subtractive manufacturing (or other) processes. While it offers significant advantages in terms of flexibility and efficiency, it also presents unique challenges in terms of fixture design, process integration, and operational expertise. As manufacturing technology evolves, the development of more sophisticated and integrated fixturing solutions is likely to continue, further enhancing the capabilities and applications of hybrid manufacturing processes.
