This is a very easy vaccum forming machiine to make if you have access to a laser cutter.
It uses a regular vacuum cleaner for the vacuum.

The goal is to use plastic pic-nic plates, mold them and pour chocolate in so that you have custom shaped chocolate pieces!

Watch the video for instruction on how to use it:

It was made at RealizeBxl by Laurent Stevens (Gnou) and Gilles Pinault.


So you will need:

  • 3 to 6mm material to cut. It can be wood or acrylic.
  • M4 bolts
  • Optionnal : a little piece of metal mesh to spread the vaccum more evenly
  • a vacuum cleaner
  • thin picnic plates
  • a way to heat the plates. We use a heat gun some people are using an oven

The assembly is pretty straight forward once the pieces are cut.

Things to improve for the next revision:

  • vacuum hole centered for a better vacuum repartition
  • maybe an hinge mechanism and a clip for the frame
  • maybe a round section in order to use a bigger part of the plate (but hten it will be slightly tricker to the plate).

Absolutely BRILLIANT! Thank you for sharing :)

Totally making me some new retainers, I have a mold of my teeth and my goal was to (potentially) bring open source orthodontics to people that couldn't afford it by 3D printing them, but I'm thinking I should just stick to vaccu-form for smoothness and lack of rigidity. I also haven't worked out how to code a program to move teeth into ideal arrangements and then build a mesh to be printed and molded.

Hi, i have a little question, how big is the diameter of the little holes in the plate?
Can you massure them? 2mm or smaller?

Hi Synchron,
the holes are 1.91mm ... + laser kerf so probably slightly larger than 2mm.

thank you very much.
I want to cut a little shield thats fit in the holes like this ([])
So i will try it with 2mm height and 2,2mm width.
