Recently, I have been using the Shopbot at Techshop a lot.
I made wooden sphere, canoe, boat and balance board.
When I found Michael's 3D scanning work of the Terracota Warriors,
I knew that I have to do it on Shopbot.
Since 2"x4" wood are abundant at the scrap box, I use them to test out the Shopbot.
For now, I used 0.25" dia ball nose but I could use 0.125" diameter for finer detail.
I was told by the TechShop DC, that they would let me mill it on clay.
My good friend at TechShop also offered to help me put the finished sculptered work in a kiln oven.
So keep watching this work in progress.
Step 1: Acknowledgment to Michael Molitch-Hou's Work.
Free 3D Printable(s) of the Week: The Terracotta Warriors of Qin Shi Huang

I used similar title "The 3D Terracota Warriors of Qin Shi Huang" as the Original Author in hope that they come up in the same google search. Note need to add 3D for better search result.
I made in at TechShop in Allen Park, Michigan. Work in progress.
Step 2: .stl to Cut3D to ShopBot .sbp
For preliminary testing, I used 2"x4" pine wood. Actual dimension 1-3/8" x 3-3/8"
I imported the stl file into Cut3D software and scale the CAD to my desired dimension.
I rotated the object so that the front is facing up or in +Z direction.
Next step in Cut3D, I define my wood stock size.
I would be using 0.25" diameter ball nose cutter.
I intend to cut the front and rear separately and glue them together.
For the front, I am cutting to 1.25" depth. For the rear, I am cutting to 0.75" depth.
Since the ball radius is 0.125", it should cover 1.75" depth for which I scaled my object to be.
I will then use a table saw to trim each of the parts to their right thicknesses.
Step 3: Shopbot Parts and Finished Works
Attached photos shown are from my first try. The discontinuity occured at the top hat and below the arm.
They would be remedied if I cut them on the same piece of wood instead of separate wood and gluing them.
In this case, I would have to use thicker wood or make the figurines smaller to fit the 2"x4" woods.
I could use these for painting practice.
Stay tune for more updates.
Thank you for viewing.
