How to Design a Simple Temple and Lord Ganesh Model in 3D Using AutoCAD and 3D Printing

By By Er. Neelakantheswar Biswal

With the advancement of 3D design and printing technology, it has become possible to create simple yet elegant models of temples and idols like Lord Ganesh. Using AutoCAD, we can design these models with precision and then bring them to life using a 3D printer. In this blog, I will walk you through the complete procedure to design and print a basic temple along with a Lord Ganesh model.

Step 1: Conceptualizing the Design

Before starting with AutoCAD, it’s essential to plan the design. Decide on:

• The basic dimensions of the temple and the Ganesh idol.
• A simple architectural style with minimal details.
• Key features like a baseWith the advancement of 3D design and printing technology, it has become possible to create simple yet elegant models of temples and idols like Lord Ganesh. Using AutoCAD, we can design these models with precision and then bring them to life using a 3D printer. In this blog, I will walk you through the complete procedure to design and print a basic temple along with a Lord Ganesh model., pillars, and a dome.

Step 2: Setting Up AutoCAD for 3D Modeling

1. Open AutoCAD and switch to the 3D Modeling workspace.
2. Set the correct units (millimeters or inches, depending on the 3D printer’s compatibility).
3. Use layers to differentiate between different parts of the model (e.g., base, pillars, idol).

Step 3: Designing the Simple Temple Structure

1. Base Structure: Use the BOX command to create the foundation of the temple.
2. Pillars: Use the CYLINDER tool to create four pillars at each corner.
3. Roof/Dome: Use a PYRAMID or HEMISPHERE to make a simple dome.
4. Entrance: Use the SUBTRACT tool to create a doorway.

Step 4: Designing Lord Ganesh’s Idol

1. Basic Shape: Use SPHERE, CYLINDER, and TORUS commands to form the body parts.
2. Refining Details: Utilize the FILLET and CHAMFER tools to smoothen edges.
3. Pose & Features: Use the MOVE and ROTATE tools to adjust the positioning of hands and trunk.
4. Minimal Ornaments: Use EXTRUDE for basic jewelry or decorations.

Step 5: Preparing the Model for 3D Printing

1. Convert the model into STL format (Stereo Lithography) using EXPORT or SAVE AS STL.
2. Check for Mesh Errors using software like Meshmixer or Cura.
3. Scale the model to fit within the 3D printer’s build volume.
4. Ensure Watertight Geometry, meaning no gaps or unconnected surfaces exist.

Step 6: 3D Printing the Model

1. Choose the Right Material: PLA or ABS for a simple and sturdy structure.
2. Select Layer Height & Print Speed: Medium settings for a balanced finish and print time.
3. Use Supports & Rafts: Enable supports for overhanging elements.
4. Print the Model: Send the file to the 3D printer and begin the printing process.

Step 7: Post-Processing & Finishing

1. Remove support structures carefully.
2. Sand the surface to smoothen rough edges.
3. Apply primer and paint (if required) for a polished look.
4. Assemble different parts if printed separately.

Final Thoughts

Designing a simple temple and Lord Ganesh’s idol in AutoCAD and bringing it to life using 3D printing is a straightforward process. By following these steps, you can create a basic yet beautiful model for decorative or religious purposes.

Happy Designing and Printing!
