Ultra-high resolution Earth topography

prusaprinters

<p>This extremely high resolution topographic globe of the earth prints in two halves, using around 350g PLA filament.</p> <p>It was created using blender, and adds small step at the coastline to aid with recognition of coastlines.</p> <p>The complete globe has nearly 8 million triangles, and so is provided hollowed and cut into two for easier printing. Nevertheless, the detail means it's challenging to slice, so I have included the GCode for Prusa mk3S in PLA.</p> <p>This globe is excellent for teaching about the earth - it is possible to see / feel every seamount, mid ocean ridge, fracture zone and trench in the oceans, as well as identify clear mountain belts land features.</p> <p>The print takes about 20-21h per half.</p> <h3>Print instructions</h3><p>Tips for printing:</p> <p>Use PLA. Silk or metallic filaments look fantastic with this and help bring out the extreme detail.</p> <p>Calibrate your elephant foot compensation before printing - this will give a much nicer seam.</p> <p>Print without support material - the inside top will be a bit messy, but it saves a lot of material and will end up inside anyway.</p> <p>Print the outside perimeters nice and slow (&lt;25mm/s) as there are a lot of direction changes and this will minimise ghosting.</p> <p>Glue the two halves together with a bit of superglue.</p>
