6. Moulding and casting¶

This week I worked in Moulding and casting 2.5d design.

Group assignment¶

in the group assignment we researched about four materials in this link

Design 3D¶

So first I decided to make an eagle badge, so I searched for a good design for an eagle and I found this one

Now I started to make this design useable in molding and casting and make it 2D so I used to software for that inkscape and tinkercad.
In inkscape I removed first the background and removed the text under the eagle.
After that I divided the eagle Into to part so we can in tinkercad extrude each part differently .
Now I export the design to tinkercad and extrude one part 6mm and the other one 3mm Here you can download the Eagle design

molding and casting process¶

In molding we used a software called srp player

First I uploded the design to the software.
Second is the type of milling I used.
Third is creating the tool path.
Fourth step is preview the results and the time it will take to finish (depend on the bit size our 1/16 inch ).
Now start cutting the design.
Choosing the right z for the bit.
The machine we will used is roland monofab srm-20 .
Here while adjusting the Z height of the bit.
And now are ready to go.

now after the cut is finished now it’s time for molding the eagle. Safety and manual - I used a silicon cube and cut it into small one. - Now I melt them here in 220 degree - after that I pour it in the eagle to make a mold of it - and last step after the silicon hardened and ready to use I poured the resin inside it to make the last shape the eagle

and this is the final result a beautiful eagle
