3D Print Mold Material Processing

          3D Print (3D Printing) , also known as additive manufacturing (Additive Manufacturing , abbreviated as AM) , which emerged in the 1990s. Unlike traditional “material-removal” machining methods, 3D 3D printing is a computer-aided manufacturing process that creates three-dimensional models through design, scanning, and other methods, then builds them layer by layer by sequentially stacking discrete materials. ( Powders, wires ) A manufacturing and forming technique. 3D Most printing processes use spherical powder as the feedstock, which is selectively melted by a focused heat source and then solidified during subsequent cooling to form the printed part. 。

At present In the 3D printing industry, metal 3D printing accounts for a substantial share. For instance, in the aerospace sector, metal 3D printing has advanced from producing test prototypes to full-scale batch production; in dentistry, 3D-printed metal crowns have become a standard practice in dental laboratories; in orthopedics, 3D-printed metal implants are now being deployed on a large scale; and in industries such as tooling and heat sinks, it is increasingly replacing traditional manufacturing processes. 。

  3D printing Commonly used in China Powder metallurgy superalloys are high-temperature alloys prepared by powder metallurgical techniques. Compared with conventional cast and forged superalloys, they exhibit a more uniform microstructure, absence of macrosegregation, and superior yield strength and fatigue performance, thereby overcoming the segregation issues inherent in conventional processing methods. (Non-uniformity is minimized.) Each particle of the pre-alloyed powder used functions as a “microscopic steel ingot,” allowing alloy segregation to occur only within the fine-scale structure of individual powder particles. This approach enhances the overall performance of the alloy, reduces the amount of machining required, and improves alloy utilization.

However, due to the 3D printing materials Macroscopic structural inhomogeneities and defects are regarded as inherent imperfections of the selected additive manufacturing process, typically manifesting as non-nominal features in the designed build geometry, such as surface texture (roughness and waviness) or residual powder (e.g., channels, pores, cavities, etc.). Thread machining, product accuracy, and so on. Especially the surface waviness and Surface finish. Therefore Advanced manufacturing methods such as AFS-D friction stir additive manufacturing or AW-DED arc wire-based directed energy deposition 3D printing may require more post-processing, such as CNC machining.

Metal 3D Printing is more precise than traditional machining techniques.   

         Precautions for 3D Printing Manufacturing ： 

1. It is recommended to tap threads rather than print them directly (including both internal and external threads).

2. Wall thickness, groove width, and font size below 0.5 mm cannot be guaranteed to print successfully;

3. For assembled parts, please be sure to request the assembly drawing; we will complete the assembly before shipment. If no such request is made, we shall not be responsible for assembly.

4. For assembled products, a 0.15 mm gap must be maintained on each side.

5. For parts with stringent local assembly requirements (such as bearing bores, diameters, and planar mating surfaces), machining allowances shall be provided in advance, followed by secondary finishing to achieve the required fit.

6. After high-temperature sintering in metal 3D printing, certain slender, thin-walled components and shell-like structures may deform. The advantage of metal 3D printing lies in its ability to produce complex geometries; however, its dimensional accuracy and surface finish are inferior to those achieved through machining.

7. Natural-colored surface with pitting (Ra approximately 7);

8. Post-processing of metal 3D-printed materials: Like conventional materials, they can undergo secondary machining and finishing processes.

9. For parts with dimensions within 50 mm, the printing tolerance is ±0.1 mm; for larger parts, the printing tolerance shall be determined on a case-by-case basis according to the engineering drawings.

10. For large components that require part-by-part printing, the parting lines must be carefully determined to avoid hole locations, account for deformation, and provide sufficient clearance for alignment during welding.
