Turn a 3D Scan into a Printable Model
In this part of our tutorial, you will learn how to repair a file from a 3D scanner. This part is composed of two sections:
The first section will be focused on repairing a very badly scanned file. The second section is more centered on a
You can retrieve the Stanford Bunny models that we use in this part
This part of the tutorial is also available in
Section 1: Badly Scanned Stanford Bunny
In this section, we will study a
4.1. Thicken a Mesh
Thanks to the purple color of the mesh and the surface icon the structure tab, we immediately spot that this model is only a surface with zero volume which is not suitable for 3D printing.
4.2. Solve Intersection Issues
We can use the Thicken tool to directly thicken the mesh to the desired thickness
We can use a cutaway view to make sure that the Thicken tool worked properly.
4.3. Repair on Sculpteo.com
By uploading your file to Sculpteo.com, you can use the very powerful online repairing tools to repair your object.
A first automatic repair leaves some holes in the mesh.
We can use other repairing methods to solve this issue. Here, the visible reconstruction method is very efficient and we obtain a printable model in the end.
Section2: Well Scanned Stanford Bunny
In this section, we will study a Stanford Bunny that comes from a 3D scanner but that has been well modeled.
4.4. Solve Intersection Issues
As usual, we check the Mesh. It is
We use the Intersections tool in the Cleanup section to identify the intersecting areas.
We zoom in.
Then, we hit the green check sign to make SpaceClaim solve these problems.
This time, the check mesh tool indicates that there is no remaining issue.
4.5. Adjust Mesh
We can use the tools in the Adjust section to smooth, reduce or regularize the mesh.
As an example, here we reduce the number of triangles by 20% which will make a lighter file that will be faster to upload and easier to handle for the 3D Printer.
4.6. Online Hollowing
A cutaway view let us know that our design is full of useless material that we can safely remove.
The easiest way to do that is to upload your design to Sculpteo.com and use the hollowing tools that are
- 1.1. Create Parts that Match Material Minimal Thickness Guidelines
- 1.2. Associate One Solid with One Component
- 1.3. Avoid Creating Intersecting Objects
- 1.4. Avoid CreatingNon ManifoldComponents
- 1.5. Avoid Creating Cantilevered Objects
- 1.6. Shell Objects
- 1.7. Add Text
- 1.8. Create Interlocking parts (Only possible for plastic, resinandalumidematerials)
- 1.9. Combine Solids
