<h2 id="settlers-catan-casting">Casting Aluminium Settlers of Catan Board</h2>
<p>A couple years ago now I started casting Settlers of Catan game tiles in aluminium. I have only gotten as far as casting the mountain(ore) tiles but I plan on eventually casting the rest.</p>
<p>To start I model a tile using Blender. Modeling the base is faily straight forward. Create a hexagon, scale it to the size you want, extrude it upwards, and then use a difference modifier to create cutouts for towns and roads. The mountains are created using an image as a height map on a seperate plain and then combined with the base using a union modifier.</p>
<p>After modeling the tile in blender I export the file then print it on a 3D printer. The print will be the form for the mold that I will cast into. The smaller the layers in the print the better as the sand tends to cling to the ridges.</P>
<p>Now that I have the form I can place it in the mold and pack sand around it. There are techniques to this but its all rather boring.</p>
<p>My furnace setup is very low tech. It consists of a pile of rocks stacked to resemble a furnace, a bag of charcole, and a small fan. A small trench is dug under the rocks to allow for airflow while skinny rocks are placed accross the trench to prevent the charcole from falling into it.</p>
<p>The furnace is started with wood and the crucible is placed into it to heat it up gradually. Once the furnace is started charcole is added, then small ingots are placed in thecrucible. It usually takes 40 minutes from lighting the "furnace" to pouring with this "setup".</p>
<p>And here is the results. They still need to be cleaned up a bit.</p>
