I love Dippin Dots ice cream but I can’t bring myself to pay $12 a pint for milk and sugar. I’d like to make them myself but I don’t usually have liquid nitrogen sitting around my house. Since I work with foundry equipment all day it wasn’t long before I asked myself ‘why not mold the ice cream’?
Unfortunately I haven’t yet gotten the dots out whole because I only have ABS right now. (The picture I took makes it looks worse that it is, it could be improved with a bit of tinkering.) I've tried hot water (which hurt), nonstick spray (which helped), and hitting it really hard and yelling at it (didn't help). I’ll be trying an acetone smoothing next but any new ideas are welcome!
This would definitely work much better if made out of a flexible material like silicone rubber. The funnel valve assembly does work well though, it holds water leak free!
In any case I included a tasty Ice cream recipe in the instructions tab!
These parts are not for beginners, I had to experiment to get it right. Here are my printing tips:
Don’t be cheap on print material because all these parts need to be strong and water tight.
The Cope and Drag parts are complex and may take a while to slice (slice time seems to depend on your computer’s processing speed).
No supports necessary for any part.
Cope: 30% infill minimum (Print with solid raft 1 interface layer, disable filament retraction)
Drag: 30% infill minimum (disable filament retraction)
Funnel: 30% infill minimum
Valve Parts: 60% infill
Get a water tight funnel by covering the valve with flavorless “Bert’s beeswax” chap stick before inserting into the funnel. Super glue the valve cap into the stem. Similarly, you will want to use the wax to seal the funnel into the cope, or just super glue the two together.
*ICE CREAM RECIPE: (be sure to clean printed parts before contact with food!)
1/8 teaspoon Vanilla Extract
1/4 cup Heavy Whipping Cream
1 tablespoon + 1 teaspoon Sugar
2 tablespoons Milk
1 tablespoon Cocoa Powder (optional)
Assemble the cope, drag, and funnel and place the whole setup on a plate (to prevent overflow mess). Then wisk all ingredients together in a bowl until thoroughly mixed. Close the funnel valve and dump the liquid delicious into the funnel up to the top. Open the valve to fill. Be sure to keep the plate level and place everything into the freezer for 3-5 hours.
