MOLDING AND CASTING

WEEK 12

Task:

Design a 3D mold, machine it, and cast parts from it

3D MOLD

Materials

  • Wax 80 % and %20 plastic
  • Cement
  • PMC 121/30

 

Machine: Roland modela

 

Software:

  • Fab Modules
  • Rhinoceros
  •  

3D mold + cast

First steps

First steps: Make 3D model a measure the correct distance

Make a mold of the 3D model and export it in .stl

Milling

Open terminal in ubuntu

  • Type sudo fab
  • upload the .stl model
  • Put the wax piece in the modela

 Select milling cutter size, material and process: "mm, 1/8, wax, rough",

The milling take more than 2 hours.

Casting

Make a mix equal of PMC 121/30

Put the mix in the wax 3d models

Wait 24 hours for dry

Remove the support

Look great but not

The mix was not consistent

So I need to make it again

Casting part two

This time look great with the same process

Comparative of the models

Hydro-sone Super X is instant cement

The mix consist 5 of cement and 1 of water

I let it dry and less than an hour is ready

outcomes

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 made your files for machining
  • Shown how you made your mould and cast the parts
  • Been surprised today
  • Described problems and how you fixed them
  • Included your design files and "hero shot" photos of the mould and the final object
