Turbomachinery plays a crucial 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 modern design demands. As a result, reducing production cycles has become a pressing issue for many enterprises. Fortunately, 3D printing technology offers an effective solution—enabling rapid and accurate prototyping while keeping manufacturing costs under control.
This article explores how 3D CAD software can be used to create detailed models of closed impellers, followed by a step-by-step guide on how to 3D print these designs, ultimately saving both time and material costs. Traditional manufacturing processes not only require precise geometric accuracy but also ensure high-quality surface finishes on blades. The tight spacing between blades and the wheel cover makes interference a common issue, making mass production difficult. However, with more accurate 3D modeling data combined with rapid prototyping via 3D printing, design validation becomes much more efficient during quality inspection.
In the early stages of 3D CAD design, Zhongwang 3D software was used to model the impeller. The process involved creating the base of the impeller and the blade structure, then combining all features using the summation command. For those interested, you can download free 3D CAD drawings and detailed tutorials from the official website: http://10868-1-1.html.
After completing the 3D model, the next step is to convert the file into STL format, which is compatible with most 3D printers. Zhongwang 3D provides seamless integration with 3D printing software, automatically switching to the dedicated interface without manual conversion. This streamlines the workflow and reduces potential errors.
The first step is to click the "3D Print" button in the File menu. Once selected, the STL file is automatically imported into the 3D printing software, allowing for quick setup and printing. Users can adjust the scale, position, and orientation of the model based on the printer's maximum build size. For example, when using an Objet 3D printer, the Objet Studio software is used to manage the print settings.
Users can reduce the model size by 50%, place it within the print area, and choose the appropriate printing material. The software then displays the estimated print time, product weight, and support material usage. In one example, the print time was 10 hours and 49 minutes, with a total material weight of 874 grams.
From design to final production, traditional methods would take days, but with the right 3D modeling software and 3D printing technology, a prototype can be completed in just one day. Zhongwang 3D’s hybrid modeling capabilities closely align with real-world enterprise needs. Through collaboration between its R&D centers in the U.S. and China, Zhongwang continues to enhance compatibility with 3D printing technologies, offering cost-effective and advanced 3D CAD/CAM solutions.
