After an intense day one of printing cookies. The baking Day #2 had arrived.
Spoiler alert EPIC DELICIOUS FAIL EXPERIMENTS.
After whole day in the freezer it was time for some baking experiments.
The set up was easy. A small oven with a thermometer inside and a rough starting baking time for about 10 minutes. It is important to notice that all the cookies where headed directly from the freezer to the oven.
First try – 175ºC
We had different quality printed cookies. Our first go was with an uneven one.
We placed the cookie on a sheet of baking paper on top of a oven rack on middle height.
It completely collapsed after 3 minutes. First fail, that was showing that the day was not going to be a success day.
Cooking for 10 minutes.
Second try – 200ºC
This one was a better print with better structural shape. It hold its shape until minute 4. Oven rack middle height.
Cooking for 10 minutes.
Third try – 200ºC
Not sure why we decided to use a oven rack, from this test on moving to a flat surface oven tray. Middle height.
This cookie had a good shape, some flaws but not that bad. In between minute 4 and 5 start collapsing 🙁
Cooking for 12 minutes. Base looks overcooks, we guess is due to the higher heat transfer properties of the metal tray vs rack and air.
Fourth try – 200ºC
Running out of Ideas. Lets try printing on top of a ceramic plate, to see having a harder to head element helps preventing the cooking from collapsing (not lots of hope on this).
The shape of this cookie is good.
Middle height on top of a cold tile (freezed for 30minutes). After six minutes collapsed again.
Conclusions
We are getting the feeling we are going to need to tune the recipe ;). Still for our next cookie printing day we have a cool experiment pending first.
As usual, the good thing about 3d food printing is that even if the result does not look as expected, still is edible and delicious 🙂 Also this infinite cookies once collapsed weirdly look like the gmail logo to us.
