design a 3D mold, machine it, and cast parts from it academy.cba.mit.edu
For this assignment I used the 3D scanned robot (scanned for the 3d scanning assignment) to be able to create a mold to make robot chocolates! The original robot scans can be downloaded here. Imported the .stl file into Rhino & realized the 3D scan had an open area that needed to be fixed.
To fix the broken mesh I used Autodesk MeshMixer which can be downloaded here.
Added a box around the model to create the mold and send it to the modela milling machine. Download the robot files here.
From Rhino I saved the model into an stl binary file to be able to send it to the modela machine and mill the mold.
Milling the mold by stages: Surfacing, Roughing, Finishing & Drilling.
From the milled wax mold we will create the food safe silicon mold.
From the food safe silicon mold we will create the robot from melted chocolate!
