ZBrush is one, if not the most powerful tools to create a High detailed 3D character. I enjoy 3D Printing and designing with ZBrush, my printer of choice is always SLA Form 2.
ZBrush + SLA 3D Printer = JOY
I want to share with you my process of how to optimize your ZBrush files with MakePrintable to get the best output for 3d printing.
- Export your Zbrush file as an OBJ/STL file format.
- Compress the file as a zip file to upload it faster
- Drag and drop the file in the upload area.
- Choose the “Advanced repair”
- Change the scale of the model to the scale you want to print it with.
- Use the High-quality option to preserve all the details of the model.
- If your model’s size is large. Use the polygon reduction slider to reduce the size. Start with a 50% reduction and increase it to reduce the size more.
- To make sure your model is watertight. (with zero holes) Increase the Clearance to close the gaps and the close holes to close the holes daaah 😉
- Hollowing can drastically decrease the price of your printing. We recommended starting with 2mm to 3mm shell thickness. This way your model will stay strong and you will save a good amount of material.
Last but not least tackle the wall thickness issues of your model which is one of the most common 3d printing problems. I found an awesome model on Thingiverse made with Zbrush by ozbruno. This model has many thickness issues in the hair.
The hair was made as thin lines that are impossible to print even on the best printers. I’ve decided to print it with and without adding wall thickness.
The original model has Non-manifold edges and a big hole on the bottom. As you can see the repaired model has zero non-manifold. The hole got closed and all the thin part have a good amount of thickness.
Printed without adding wall thickness.
Printed with wall thickness
After finishing repairing and optimizing your Zbrush file. You have two options.
Download the model as an STL and print it at home or print it with a printing service such as Shapeways or i.materialise.
That’s it for 3D Printing ZBrush files. If you enjoyed this article check out 11 reasons why to use MakePrintable.
