Convert Digital Elevation Model files into STL files for 3D printing

STEP 1: UPLOAD DEM & SELECT REGION

To get a DEM file of your area, go to https://apps.nationalmap.gov/downloader/ and download the DEM file (these can be 200-500 MB).

Drop DEM file here

GeoTIFF (.tif, .tiff) - max 500MB

Load DEM file to see map

Pan and zoom to select the area you want to process. The current map view defines your region of interest.

Warning: If you see a diagonal line through your image, try selecting a different/smaller area. This is a known bug without an easy fix.

Complete steps 1 and 2 first to enable 3D rendering

GeoTIFF (.tif, .tiff) format only. Maximum file size: 500MB.

Multiplies terrain height for dramatic effect. Higher values show more detail but may require supports.

Adjust base height for stable printing. Lower resolution processes faster but reduces detail.

Reduces noise in terrain data. Apply light smoothing for cleaner prints without losing detail.
