-
I used tinkercad to design the model here I used the text to write the first two litters of my name
-
To make a hole I used the basic shapes cylinder as a hole creator
-
to create the base I used the box and then rounded the edges
-
to finish and combine all parts together I used the combine tool
-
then click on export as .stl
Milling software¶
-
I uploaded my model from file >> open ,we made sure that the orientation is correct and the dimensions too
-
To start we added the tools for milling the wax from Options >> my tools
-
-
After that we chose the type of milling
-
click on create toolpath ,then edit it and set the material to mill so that the software would generate the feeds ,speeds settings. Moreover, I chose the milling bit
-
for roughing and finishing we will use the same milling bit which is 1/32 ball nose
-
To make sure that the milling in the edges will happen I added a slope of 30 degree
-
For the finishing I used the same milling bit 1/32 ball nose
-
Then to preview the final result I clicked on show model this will indicate if I will have to adjust or change the milling bits
-
I zeroed the x,y axis to the middle of the wax and z on the top of the wax
-
Finally I clicked on start cutting
Milling¶
-
I draw a X to find the center of the wax
-
I changed the milling bit to 1/32 ballnose
-
this vid shows the start of the milling
4.This was the materials and tools I needed
5.for this material I had to mix 18.3g “1-1 ratio” to make the negative mold
- for the cast I used jepsum with 1-1 ratio with water
