On my quest to print more types of food, I wanted to learn as many as possible different extruding mechanisms. At the same time, being a newbie at Pier9 I will be using this instructable as a soft start to use the 3d printers we have here (connex 500).

The goal is to print and test two different designs of progressive cavity pumps and hopefully get to learn some along the way.


Step 1: 3d Printing First Test

First tested pump is designed by emmett and is available on thingiverse. Printing with the Objet Connex 500, was easier than I could expect. Specially following the pier 9 basic user manual. First it felt weird not having control about the slicing process, the same way you do with FDM-RepRap printers (Slic3r, Cura, ...). But could not be happier with the result.

Cleaning the support is tedious but fun. I love the splashing machine.

<p>Thanks that was informative!!!</p>
<p>So, you're working on a printer for food?</p><p>What other mechanisms have you tried (or are you going to try)?</p><p>Contact with food is obviously an issue - it seems like a good excuse to persuade Pier 9 to invest in other printer technologies, maybe laser sintering so that you can make your parts in food-safe metals!</p>
hi! Thanks for you comment, so far I have been playing with peristaltic pumps, air extruders, some powder extruders and syringe extruders too. Definitely I am going to use my time at Pier 9 to explore as many options as I can.<br>You are totally right, metals would be the easiest way to get a 3d printer to print food-safe parts.
