16.Molding and Casting¶
group assignment page¶
SAFETY DATA SHEET¶
I used this (PDF) file to follow the safety steps and be careful in using the materials that I will use
Datasheets¶
Design¶
1.I started with simple text sketch in fusion360
2.Then I extruded the text
3.Then I sketcked and extruded a plate
4.I added some fillets
File preparation¶
5.i opened srp player and imported the design
- srp player
6.I chose type of milling
7.i set the toolpath and added 2mm margen in all the sides for safety
9.The first toolpath will be roughing
10.Then we chose the mill bit
11.then the model origin is in the middel
12.Then the finishing toolpath
14.I set the operation for our roland SRM-20
15.we zeroed the axiss
16.A warning showed up and we skipped it
17.the we started milling … of course before that we sticked the wax block in the machine using double sided tape
Milling¶
18.i measured the center of the block
19.we sticked the wax block in the machine using double sided tape
22.milling has startted
23.a small pice of the block got off so i had to glue a piece to hold the structure and stop leaking
MATERIAL SAFETY DATA SHEET¶
silicon casting¶
28.I used for the negative mold silicone with a ratio of 50/50 so i needed 26g so each will be 13g
30. I started with 13g of product A
31.Then with 13g of product B
33.i mixed them together
36. after that I poured mixture to my positive wax mold and knocked the walls so any bubble can go out easily
37.I left it to cure for 24hours
Epoxy casting¶
38.For my cast These are the tools I need
39.I took off the cured mixture
40. for the cast I used epoxy 1/3 ratio where i poured 75% of resin and 25% hardner
42.I mixed them together
43.I had an idea to color my mixture so i used a marker to get the green color and mixed it with them
46.I poured the epoxy in the negative mold and i also had an idea to put some LEDs
49.i used heatgun to get out the bubbles
51.After 24 hours i took out the cast out
54.
