Dosing pumps & DIY options

The main reason I was considering a full-automatic tempering machine was to have a dosing pump. I then found Hilliard makes one that which costs significantly less, though still around USD$5,000.

Researching various pumps it seems that peristaltic pumps could be a very affordable way to hack it together. There are even a few people 3D printing pump heads through which you could put a food-grade hose.

Are there other cheap options I should be considering? Has anyone gone the DIY route and have advice to share?

Ah, thank you! For some reason this didn't show up in my search results.

What information did you find about peristaltic pumps? I was hoping to find/buy a cheap one but no luck. Is printing one the best way to go?

I found a model for about $350 at simplypumps - it's hard navigating the different models online and they seemed the most approachable for beginners. I've had a 3D printer but don't like the look of the material and I'd also need to buy a motor; I prefer having something that should be resellable.

Which one did you go with? Can you provide a link?

Sounds like a fun project!!!!  Let us know what system you come up with...

As soon as I build the other stuff, I intend to get the  PM600 .

Other stuff meaning: a heated container and a vibrating machine. Yesterday I realized putting chocolate in moulds isn't the actual bottleneck just yet. I spend a good chunk of time manually removing bubbles and feel the need to work faster because chocolate is starting to crystallize.
