Guidelines for CNC Landscape Models
CNC Milling of Landscape and City Models
Use the .stp file format if possible. If your software can’t export .stp, a .stl file also works, though it can sometimes cause issues. Your 3D model must be a closed solid – not just a surface. It needs side walls, a bottom, and closed curves, like in the example below.
The maximum material thickness is 40 mm, so keep your model under that. If you need more height, you can stack two pieces for a total of 80 mm on the large CNC.
We sell pre-glued pine sheets up to 1500 × 1000 × 40 mm. The price is 0.067 DKK per cm² – for example, a 50 × 40 cm piece costs about 135 DKK.
Machining cost:
10 DKK/hour on the Roland CNC
20 DKK/hour on the VHF CNC
A typical landscape model takes 3–6 hours, depending on detail level.
When you’re ready, model the stock (your material block) around the landscape. Make it about 30 mm larger on all sides – this gives space for screws to hold the material in place. It should look like the example below.
When your file is ready, send your project request to Emil at ejas@kglakademi.dk.
