How to Create a 3D Model of a Person for 3D Printing: 1 Minute to Mastering Human Models for 3D Printing

Creating a 3D model of a person for 3D printing is a rewarding process that involves several key steps, from capturing the subject to preparing the digital model for printing. Whether you’re an artist, hobbyist, or interior designer looking to personalize a space, knowing the right workflow can ensure professional results. Let me guide you through this process as both a designer and a tech enthusiast.

1. Capture the Person
2. The most accurate way to model a real person is with 3D scanning. Options include hand-held 3D scanners, photogrammetry (using a series of photographs from multiple angles), or scanning booths. For photogrammetry, take overlapping photos around the person, ensuring good lighting and neutral background.
3. Process the Scan or Photos
4. Use photogrammetry software (like Meshroom or Agisoft Metashape) to convert photographs into a detailed 3D mesh. If you used a 3D scanner, import the scan into your chosen software. Clean and refine the scan, removing any extraneous geometry.
5. 3D Model Cleanup & Sculpting
6. Bring your model into sculpting software, such as Blender, ZBrush, or Meshmixer, to repair holes, smooth rough surfaces, and enhance details. At this stage, you may retopologize the model for better printability and optimize polygon count as needed.
7. Prepare for 3D Printing
8. Make the model “watertight” (no holes or non-manifold edges), orient it properly, and consider separating it into printable parts if necessary. Export the model in .STL or .OBJ format, common for 3D printers.
9. Slice & Print
10. Import your model into slicing software (e.g., Cura, PrusaSlicer) to generate G-code for your specific 3D printer. Adjust print resolution, supports, and infill according to the level of detail you want. Start printing!

As a designer, I always advise planning how the resulting figure will be used or displayed within your space. For instance, a personalized 3D figure could be displayed in a modern showcase or serve as a unique accessory on a bookshelf. Before you finalize your model, consider utilizing [3D Render Home](https://www.coohom.com/case/3d-render-home) to visualize how your printed piece will look in different interior settings—this step helps ensure the model’s scale and design complement your overall aesthetic.

Tips 1:

Pay special attention to the subject’s clothing and pose—subtle details greatly enhance realism. If you intend to paint your 3D print, model and print in a slightly larger scale for easier handling and finishing.

FAQ

Q: What’s the easiest way for beginners to create a 3D model of a person?

A: Photogrammetry with a smartphone camera is cost-effective and beginner-friendly. Many free apps and software can stitch together the images automatically.

Q: What file format should I use for 3D printing?

A: STL is the most common format for 3D printing due to its compatibility with most slicers and printers.

Q: Can I create a 3D model without a scanner?

A: Yes—photogrammetry uses regular photos, or you can model from scratch using sculpting software, though this is more time consuming and less accurate.

Q: How can I ensure my model is printable?

A: Make sure the model is watertight, has no non-manifold edges, is correctly oriented, and doesn’t have overly thin features.

Q: How long does a 3D figure take to print?

A: Depending on size, print quality, and printer speed, small models can print in 2–4 hours, while larger/high-detail figures may take 8 hours or more.
