DIY cookies

Perhaps you read the post “Prodlenki” about acquaintance of children with the profession of a programmer - As we explained to children who a programmer is (I remind you, Prodlenka makes interesting free events for children with the best Russian and foreign experts. And they broadcast freely throughout the country).

The next lecture (February 22) was about confectioners . The idea came - is it possible to make a “link” between programmers (IT specialties) and confectionery? I talked to the organizers - it turned out that there are enough intersections: there are 3D printers that print sugar, 3D modeling can be made for pouring chocolate, there are delta 3D printers for baking, there are chocolate 3D printers.

But we stopped at the simplest - this is the creation of 3D molds for cookies.

It was necessary:

• create a 3D form model
• print on a 3d printer,
• make cookies
• to treat the guys at the event

Before the event, there were a few days left, about how everything was - from the idea to the realization and there will be a story.

Find / come up with a cookie shape

Forms for cookies are not something new, I remember about them was a post on the Habré, and we were in the hackspace printed a mold, and the participants baked , and this is what happened:
.

But I wanted to make cookies thematic - by February 23 (the event about pastry chefs was on February 22). Immediately I thought to make a star, but this is somehow not original, so I decided to make a mold for the plane.

After a short search, I stopped at this — meet the T-50, the 5th generation fighter:


Here is his model:


On the basis of this model, using the free and open graphic editor GIMP , a mask was made:



The mask for the form is ready, now you need to make a 3D model.

Make a 3d model cookie cutters

The question of where to do was solved simply - the cookiecaster.com service. This is a free specialized service for creating cookies for cookies:



The principle of the service is simple - with the help of the mouse, we press on the working area, and lines are created between the points where we clicked, after the figure is completed (pressing the starting point) - the figure is displayed in the upper right corner - a preview.

For example, let's make a simple figure, a triangle:


We see on the right a display of the form created by the program (in addition to the contour, the program creates a small frame at the initial level - this increases the strength of the model). It is also possible to edit the “nodes” of the model, and we can click on the “edges” and make convex / convex outlines.

Below the preview screen are the settings for the size of the 3D model being created:

- the maximum size of the form (Large 4 ") - (4 inches = 10 cm)
- height (0.65 ") about 1.5 cm
- wall thickness - 2mm

You can change these settings to get molds of different sizes.

And below the button to download the form for cookies - Download 3D File . Click and get cooke.stl file (3d model in STL format).

The service has the ability to download images - Trace . In this case, you can "trace" the contour of the picture.

Download our template. And we can "click" on the contour.

But to automate the outline of the contour, the service provides the function “Magic trace” - this function allows you to find the outline of the object. Click on it, and after that - click on the "body" of our contour plane, and the system itself creates a contour. Here's what happened:



3D models were made - for different sizes of cookies. STL files can be downloaded from here .

Here is what STL models look like in the Cura 3D printing software:


You can read more about the estimated print time in the Cura program here (the presence of a 3D printer is not necessary).

Print a 3D model on a 3D printer

The guys from the Moscow hackspace Neuron agreed to help in the printing of the molds ( Laboratory of the three-dimensional printing , thanks to Ivan).

Here's what it looked like:


Printing process:


And ready mold:

Make cookies

In the manufacture of cookies helped Julia (Project Manager Prodlenka).

Here are her photos of the manufacturing process, based on the recipe :


The dough is made, rolled out, and on it using cookies we make cookies:


And after that we bake in the oven:

Result

Here is the story about 3D cookies at the event:


And Julia demonstrates the result:

Bonuses

If you want to make a 3D form using the cookiecaster service, then a bonus for you.

I talked with Ivan (Moscow) from the three-dimensional printing laboratory , and they offer a 15% discount on all March for the printing of 3D molds for cookies (the average price is 150 rubles / form).

We also, in Yekaterinburg in MakeItLab hackspace , provide the entire March with a 15% discount for printing molds for cookies.

Can someone make cookies by March 8th :)

You can find a lot of ideas for 3D models on the Thingiverse service, for example, a cookie cutter request - returns more than 1000 options.

Let me remind you that you can search for 3D printing in your own cities - in hackspaces, in fab labs, in TsMITs, and simply in companies providing 3D printing services. It is recommended to print cookie cutters from PLA plastic.
