13-Molding and Casting¶
Assignments¶
Group assignment:¶
- Review the safety data sheets for each of your molding and casting materials
- Make and compare test casts with each of them
- Compare printing vs milling molds
Individual assignment:¶
- Design a mold around the process you’ll be using, produce it with a smooth surface finish that does not show the production process, and use it to cast parts.
Learning outcomes¶
- Design appropriate objects within the limitations of your process
- Demonstrate workflows used in mold design, construction and casting
Have you answered these questions?¶
- Linked to the group assignment page and reflected on your individual page what you have learned
- Reviewed the safety data sheets for each of your molding and casting materials, then made and compared test casts with each of them
- Documented how you designed and created your 3D mold, including machine settings
- Ensured your mold has smooth surface finish, that does not show the production process (by postprocessing if necessary)
- Shown how you safely made your mold and cast the parts
- Described problems and how you fixed them
- Included your design files and ‘hero shot’ of the mold and the final object

Individual Assignment¶
This week we were tasked with making a mold with the design of a 3d tool path.
Difference
2.5D toolpath- Straight z extrusion from a design
3D toolpath - Has to have different levels of printing.
Errors¶
1- First of all, I did not know about the whole 2.5d design requirement, so I made 2 of those designs
2- Then, I thought we needed to print the box, or needed the box with the design(not sure why, it was a dumb thought) so my designs have the box around them as well.
3- Then another mistake I made was trying it out on tinkerCad. It was easy to use, but I was more familar with fusion so the design for this didn’t go too well either, so in the end it was a waste of time.
I loged into TinkerCad here
Actual design¶
With the whole 3d toolpath required, in the end, I made a spear. I cut it from halfway so it can be cut.
Then my local instructor told me its a bit too plain, so I added a few extra designs. They were slopy, but I was running out of time so I just went with it.
