![]() We don’t have a single, ‘one-size-fits-all’ wall thickness to recommend for each and every 3D printing material. Material that is not used for building your 3D print can then be removed.Īre the walls thick enough for a hollow model?Ĭreating a hollow model means that you need to design your object with ‘walls.’ A printer needs to know how thick the walls of your objects (the ‘outer shell’ if you will) are supposed to be. If you would like to avoid this, you can add ‘escape holes’ to your design. ![]() However, since our printers print layer by layer, 3D printing material can get trapped in the interior of your model as you can see in the image in the middle below. With a hollow model the interior of your print will be empty. Solid designs are not necessarily a problem - depending on the material they will be stronger and harder to break, but they will also be more expensive as more 3D printing material will be used. Reduce costs: create a hollow 3D model & 3D print.Ī hollow model means that the interior of your object will not be solid. So let’s take a look at these things a step at a time. However, creating a 3D model with an empty interior can be a bit tricky: you need to know how to hollow your model in the 3D modeling software you’re using, you need to define a wall thickness that is strong enough for your model not to break, and it probably makes sense to add so-called ‘escape holes’ to your model. ![]() Save money using less 3D printing material
