WEEK 12. Molding and casting

group assignment:

  review the safety data sheets for each of your molding and casting materials,
     then make and compare test casts with each of them
  extra credit: try other molding and casting processes

## individual assignment: design a mold around the stock and tooling that you’ll be using, mill it (rough cut + three-axis finish cut), and use it to cast parts extra credit: use more then two mold parts

Objectives

my objtive this week is to make a node

1. the realsaion of the mold

a The design

For the realization of my mold I used the solidWorks to model it and generate an STL file

b preparation on vcarve

explaining steps :

 1 open V carve and create a new file

 2 import the the STL file usi,g the modelind tool on vVcarve

 3 put your piece in center of your space put your prt size

 3 then import the model

 4 choose your tool and calculate the toolpath

 5 then choose the processor and generate the the machine file (rml...)

  • Cutting parameters

  • fabrication tool

  • fabrication fist Open the roland software

  • choose the gcode file from your folder by clic on “add” then out put

  • After fabication

### 2 chemical preparation for the mole

2.1 choice of material

i choose tHE LIQUID SILICONE RUBBER before begin to us it i try to surch somme knowledges about.

what it is ?

2.2 what i learned and use such as instructions

i link this instruction to use the product and the mold building with Liquid Silicone rubber

  • prduct datasheet

here is how the model was made

## Creation of the piece

I followed the instructions from the SMOOTH-CAST 300 product website

### mixed and cast

summary

what learned:

i didn’t put the guide to fixe the mold part toget easely so it was verry difficult to build the mold before casting.

i recommand to to make it for all mold.
