Fixing Your 3D files
What is Meshlab?
Limitations of Files for 3D Printing
You're likely getting your 3D Models from all sorts of places. Fusion, ZBrush, Thingiverse. There are even people 3D Printing Chocolate Brains from their own MRI Brain Scan Data.
Your models may have a few issues.
- Huge File Size: Sculpting tools like Zbrush generate meshes that run north of a million polygons. This is a lot of data for a program to manage.
- Reduce Errors in Mesh: Remove topological errors, duplicated vertices, degenerated faces. Remove unwanted areas.
- Incorrect Resolution: Your 3D Model might not need a very high resolution in the 3D Model if you're printing it at a very small size.
- Incomplete Mesh Data:
- Nature of Mesh Data: These include meshes that by the nature of their existence could have issues in the mesh. Some programs generate data from brain scan MRI's for example. We also may experience issues with generated 3D models, 3D Scans, Photogrammetry Meshes, Point Clouds and the like.
What Can You Do With Meshlab?
1. Clean & Reconstruct 3D Laser Scan Data
From the menu, select
Remeshing, simplification and construction
Quadratic Edge Collapse Detection.
If your model is textured, there is also an option (with texture) that will do a good job at keeping your textures positioned properly.
2. Generate Mesh from Point Clouds
3. Use Meshlab in a workflow to make an edible chocolate brain from your own MRI Scan?
1. Convert sliced DICOM data into STL file format with InVesalius3
2. Cleaning up the model in Meshlab
- Remove Unwanted Data
- Perform a Poission Reconstruction which files any holes in the scan data so that it's now waterproof.
3. 3D Printing a solid model
4. Produce a Latex Mold
5. Cast the Chocolate and Eate
Other Things It Can Do
3D Acquisition (From Scan to Mesh)
- Color Mapping & Texturing
Scaling, Positioning & Orienting
Converting Between Different Formats
Preparation for 3D Printing
Using Meshlab to Clean and Assemble Laser Scan Data
Using Meshlab to Clean and Assemble Laser Scan Data: Meshlab is an open source software program used to manipulate and edit mesh data. This tutorial will specifically show how to assemble, clean and reconstruct data from a 3D laser scanner. The techniques used with the scanner used here should ap...
Polygon reduction with MeshLab
The maximum amount of polygons our printers can work with is 1 million. Some tools like ZBrush can quickly create a high polycount, so it's easy to run into this limit. Fortunately there's a solution known as polygon reduction (also known as mesh decimation).
How to fix your 3D files with Meshlab Software
Posted By Marianna Papageorgiou on Oct 10, 2017 | At Sculpteo we tend to think that formation is the greatest tool for self-improvement. Since 3D modeling is totally connected to 3D Printing, we constantly try to provide you useful tutorials about how to prepare your model for 3D Printing using your favorite CAD software.
Edible Chocolate Brain From MRI Scan
Edible Chocolate Brain From MRI Scan: Overview This instructable will show you how to create an edible chocolate brain from sliced data sourced from an MRI scan. Our colleague at Inition, Andy Millns had his brain MRI scanned as part of a research project (he didn't say what into!) and...
Generate mesh from point cloud in MeshLab
Simple video guide to create 3d mesh from 3d point cloud using MeshLab software. You can get more info from the following posts: - https://clintbrown.co.uk/...
MeshLab: Point Cloud to Mesh
Availability / usability: This is free, open source software available from www.meshlab.net MeshLab does have the function to convert a point cloud into a mesh but be warned - it can take a long time, it will often crash and the results may not be as good as you would like.
