Project Demo Week!

That's what happens when it falls on the ground


This was one of the most interesting weeks. We needed to create a wax template of whatever we wanted, mold silicon to it (we used OOMOO) and cast with either DryStone or HydroStone.

Since next week is also the Media Lab's demo week I had very little time to work on my mold.
I decided to create something simple that at least will give me enough experience to create something far better next time i'll have a chance to play with this.

I had no real difficulties creating my mold, it was all pretty much straight forward since I didn't do anything complex. Simple is really simple apparently :)
Machining was almost the same process as in our make something big" week.

Pouring the silicon required following precise steps, but there's no reason for me to write them down since they exist in our tutorial page. I followed them and it just worked perfect. The reason i'm not putting links is because they're not yet online (by the time you're reading this they probably are).

The little I can say is that I used the hot-glue gun to glue the blue wax box onto the wooden platform. The platform was there in order to fixture my material to the machine's (Desktop ShopBot) platform.

- When you pour the silicon / casting material, use the flat wooden stick to guide the fluid into the cup / mold
- Be careful when you take photos of the ShopBot working - I accidentally moved it and ruined a part of my mold :(
- Make sure everything is ready for the molding / casting material before mixing the liquids. I forgot to wrap the mold with tape before I mixed both substances and ended up rushing everything (which I probably didn't have to but did anyways..)
- If you're making parts that should have an exact shape or are made of several parts, make room for the casting material to enter and have one hole for the air to get out
- It took the silicon about 3 hours to be ready for casting
