Moulding and Casting

  • group project

review the safety data sheets for each of your molding and casting materials, then make and compare test casts with each of them

  • individual project

Design a 3D mould around the stock and tooling that you'll be using, machine it, and use it to cast parts.

Learning outcomes:

  • Design appropriate objects within the limitations of 3 axis machining

  • Demonstrate workflows used in mould design, construction and casting

Have you:

  • Explained how you designed your 3D mould and created your rough and finish toolpaths for machining

  • Shown how you made your mould and cast the parts

  • Described problems and how you fixed them

  • Included your design files and ‘hero shot’ photos of the mould and the final object


Should I read the MSDS and TDS this week?


  1. It is always a good idea to read these documents.

I want to only make a wax mould, and cast something in it - is that acceptable?


  1. Learn and go through the 3 step process first . To break the rules you have to master the rules.

Can I 3D print the mold? Can I do a lasercut?


  1. No, for this assignment you must mill the mould using a CNC milling machine.
