Why Mammoth Will Become our Default Mesh Repair Tech

Our team initially launched Mammoth under our lab section to not only give you a sneak peek of our upcoming new Mesh Repair Tech, but also to receive and incorporate your valuable input before we launched it as part of MakePrintable.

Feedback has been amazing as everyone prefers Mammoth to our previous standard mesh repair tech. As a result, we are planning to set Mammoth as the default mesh repair tech for MakePrintable much sooner than expected.

In case you missed the recent announcement, Mammoth is a new reconstruction algorithm that uses voxel technology and GPU cloud computing to rebuild meshes for 3D Printing. One of the main advantages of using Mammoth is it can repair large models with an extensive amount of detail. That’s why we named it Mammoth, as mammoths are a large species with a lot of hair. If you’re into 3D printing, you know hair is one of the hardest things to print since it can be very thin in certain areas.

The first model below was uploaded to Thingiverse by Dylan Hirsh. As you can see, it has a lot of intersection geometries. You can see what happens to it on the slicer after we fixed it with Mammoth, through our before and after pictures.


Before Repairing and After Repairing with Mammoth:


In the before version, you can see how the image is not filling up properly. The slicer simulation emulates how the 3D Printer will print this model. If this model were to be printed without repair, it will likely lead to weak structures that could collapse. The after version shows how Mammoth repaired and optimized the model and the structure is now uniformly built with a fully integral mesh.

The second model below was uploaded to Thingiverse by Carlos Stone. The model is packed with some flipped faces and boundary edges. If you attempted to print this model without repair, it would likely lead to a “spaghetti looking” print due to the missing layers in parts of the mesh. The after version shows how Mammoth repaired and optimized the model and now it’s finally integral and ready for print.

We’ve tested a model to see how mammoth can fix some of the troublesome 3D files. As we like a good challenge, the model we selected had many non-manifolds and intersecting geometries. Check out the after picture to see the amazing results after the Mammoth repair!

Finally and like most people, we love monkeys and came across this cool model on Thingiverse thanks to Lin Chio. Although the model was challenging, it was easy to repair with Mammoth. After repairing, I decided to 3D Print it because it would look cool on my desk 😉
