Many metal 3D printed parts require traditional machining processes such as milling and EDM to generate accurate surfaces. However, metal 3D printing technology often produces parts that are difficult to achieve with traditional technology. They have unconventional and complex shapes, which will pose challenges for subsequent connections with other processing technologies.

In the subsequent processing, the clamping of the workpiece is an element that needs to be considered in the metal material additive manufacturing process. Because the size, shape and material of 3D printing will be related to the fixture solution in processing.

According to the German fixture manufacturer Xiongke, when using a five-axis machine tool as a post-processing method for 3D printed parts, at least 1×8 inches of material should be clamped, or a tuxedo fixture should be used, or a positioning pin should be placed directly on the workpiece , So that the entire processing process can be completed at the same time.

Therefore, in the early stages of the design of 3D printed parts, it is necessary to plan in advance the clamping scheme of the parts in the subsequent processing. A reasonable part design can keep the parts simpler and more reliable in the subsequent processing. For example, positioning hole fastening features can be retained in 3D printed parts, while large 3D printed parts can also retain compressed pieces or concave areas of fixtures or bolts.

If the 3D printed part contains some non-critical hole structures, it is sometimes best to drill holes after printing. The reason is that although the characteristics of the holes can be directly realized in the 3D printing process, in order to consider the size and accuracy of the holes, it often brings challenges to the manufacturing design of additional materials. In addition, if the position of the printed hole is not accurate, it may be necessary to manually modify the subsequent trimming of the three-dimensional printed hole structure, thereby affecting the processing efficiency. Therefore, it is a better method to realize this non-critical conventional pore structure through processing.

The increase of metal materials has greatly released the design freedom and brought space for product design optimization. However, when metal materials are used as a final part production technology, how to effectively combine with subsequent processing technology is that metal 3D printing technology has become A normal production technology needs to cross the threshold.

The GF machining solution integrates the 3RDelphin fixture system into the DMPFactory500 equipment, enabling the operator to seamlessly place the building substrate on the fixture, and transfer the metal material from the added manufacturing equipment to the wire-cut EDM equipment or in the subsequent process Milling machine. This not only saves the clamping time required after the parts are separated from the building substrate, but also saves the manufacturing time of the special fixture. For example, in the manufacture of orthopedic implants, manufacturers can directly 3D print the implants on the tool plate for milling in the post-processing process, which helps fixtures and fixtures in the conversion process of different equipment accurate locating.
