How to Use OpenVDB to Help Prepare or Fix Files for 3D Printing

3D Printing OpenVDB Tip

Sometimes you find an old file in your folders and think, "I'll trying printing that" but your heart sinks when you look at how a 3D printer might just make spaghetti out of it, or it'll cost a fortune if you don't hollow it out. Thankfully I've discovered a helpful use for the new OpenVDB in Cinema 4D R20.


I've always been a big fan of 3D printing. The ability to take something that was a digital file and then hold it in your hands a few hours later has been an awesome experience for me as a 3D modeller.

When playing with the new R20 features, being able to skin or remesh an object with the new OpenVDB lit a light bulb above my head. Then when I realised you could use the Dilate/Erode tool to hollow out objects, the bulb exploded! But it's ok, I figured out how to print a new one!

In this video, I look at how the new OpenVDB workflow can help people prepare files and sort out issues ready for 3D printing.

First, I look at how the Volume Builder can help build seams and merge 3D models to create a single surface.

Then I look at how you can use other shapes to help underpin areas that might have hollows.

Finally, I show you how to use the Dilate/Erode functions to create a hollow version of your model to help save on material printing costs.
