<p>I'm looking for a way to slice up a 3D model and then get the profiles of each individual layer. I need to 2D print the different layers (with the layer height that I define) for a Styrofoam craft.</p>
<p>Thank you very much!</p>

With OpenSCAD, you can
```
import
```
the STL file and apply
```
projection
```
with
```
cut=true
```
at successive Z-axis
```
translate
```
operations, and write out the result as SVG. This can all be automated from the command line to product a series of SVG files for your layers to "2D print".
