Turbomachinery plays a vital role in the national economy, especially within the heavy industry sector. The complex geometry and intricate manufacturing process of closed impellers make it challenging for traditional methods to meet design requirements. As a result, reducing production time has become a critical issue for many enterprises. Fortunately, 3D printing technology offers an effective solution. Not only does it allow for rapid and accurate prototyping of impeller samples, but it also helps control manufacturing costs. This article explores how to use 3D CAD software to create and print a closed impeller model, helping save both time and materials.
In traditional manufacturing, ensuring the geometric accuracy and surface quality of blades is essential. The tight spaces between blades and the wheel cover can lead to interference issues, making production difficult. If the 3D modeling data is precise, combined with rapid prototyping via 3D printing, it becomes easier to evaluate the design during quality inspection. This approach ensures that any potential issues are identified early on, leading to better outcomes.
The process starts with 3D modeling using Zhongwang 3D software. The main steps include creating the impeller base and blade structure, followed by combining all features using the summation command. For those interested, detailed tutorials and free 3D CAD drawings are available at http://10868-1-1.html.
After completing the 3D model, the next step is to convert it into an STL file, which is the standard format for 3D printing. Zhongwang 3D provides seamless integration with 3D printing software, automatically switching to the dedicated interface without requiring manual conversion. This streamlines the workflow and reduces errors.
Once the STL file is ready, it's imported into the 3D printing software. For example, when using an Objet 3D printer, the software used is Objet Studio. Adjustments such as scaling, positioning, and material selection are made based on the printer’s capabilities. The product size is reduced by 50%, placed on the print bed, and the appropriate material is selected. The software then calculates the weight of the printed part and supporting structures, along with the estimated print time.
The final print takes approximately 10 hours and 49 minutes, producing a 590g impeller with 284g of support material. The total material required is 874g. After confirming the settings, the 3D printing process begins, resulting in a high-quality prototype.
Compared to traditional manufacturing, which can take weeks, 3D printing allows for a complete sample to be produced in just one day. Zhongwang 3D’s hybrid modeling technology, developed through collaboration between its U.S. and Chinese R&D centers, continues to enhance compatibility with 3D printing solutions. This ensures that enterprises have access to the latest, cost-effective 3D CAD/CAM tools.
