A Cookie Recipe that is
Printable, Bake-able, Edible

The shortbread recipes has enough resolutions to print individual teeth on a Wades gears, Cookie is ~ 4″ or 100mm

1  cup of flour

½ cup of powdered sugar

Mix thouroughly

1  stick of butter

½ cup of honey

1  teaspoon of vanilla

¼ – ½ teaspoon of salt (optional)

Makes 10-15 50cc syringes print with Green luer lock.
Bake 7-12 minute @ 350 degrees F for Greg Wades 4″ cookie.

 

 

(Use  finely ground the ingredients to prevent clogging)

Out of the 10+ iterations of cookie recipes, a shortbread cookie is the closest to a good resolution cookie. Making a cookie recipe that frostrudes is easy. Keeping the print resolution after baking is tough.

The wetter the cookie dough the easier it frostrudes… and the less resolution you get after baking

 

 

Finding a balance between ease of printing and baking resolution while maintaining taste was the hardest part. By no means do I claim to understand all of the chemistry involved in a cookie recipe. I don’t think any organic chemist would claim an understanding of the cookie as a whole. What is apparent; is that any baking soda, or baking powder causes rapid expansion. And, any water in the recipe allows the cookie to slump down and spread out.

Trouble shooting colloidal suspensions (itty bitty particles floating in some sort of fluid).

Originally, back when I was printing with Crab gel. I thought bits of something, were clogging the frostruder. After working with the cookie dough recipes it became apparent that pulsing pressures are a great way to separate out a fluid from a colloid suspension. Which turns out to be a major hurdle in printing with composites like cookie dough. This property may come in handy later, for separating, oil from sand, nano particles from a polymer, or whatever. Regardless the separating is some sort of physical property, and others ran into this problem. The claystruders at unfold~fab have an article on their trial working with clay.

They worked under continuous pressure which largely by-passes this problem, this solution limits my designs, but the work they are doing at Unfold~fab is excellent.

Enjoy the recipe.

    Love it. A friend back in high school used to draw bizarre creatures that only lived in his (twisted, apparently) mind. He’d love this, as he could make his own custom box of animal crackers!

    Suggestion for a different material, since I don’t see right now where to put the suggestion:

    Synthetic Lunar Regolith. Perhaps you’ve tried it or thought about it, or even posted it and I haven’t seen it, but just in case you haven’t yet… There’s going to be a need to make things on the Moon with what’s there, and what’s there is a lot of powder. Recently we’ve learned that there’s also some water trapped in at least a few places. Aside from using binders, and after watching the Solar Silica Sand Sintering machine, I’m convinced that unfiltered sunlight is itself a usable energy source for sintering. Anyhow, food for thought while enjoying the (cookie) food for body.

    David, check out the UW Microgravity team. They have a design for “sifting” Regolith which is the first step necessary for 3D printing.

    Awww, this looks very delicious!

    Wow! 3D Printing Cookie Dough is so cool. Imagine branding your own cookie or cake with full customization. I’m so excited about 3D Printing.

    Moin,

    Eine spannende Thematik die ihr hier gerade erwähnt. Ich bin auf jeden Fall gespannt wohin die Reise geht!

    Es bieten sich hier ja unzählige Möglichkeiten. Auch für den Privatanwender sehr lohnend, gerade für

    kleinere Reperaturen im Haushalt. So muss man sich nicht immer eine komplett neue, sagen wir in diesem

    Beispiel, Lampe kaufen sondern druckt sich einfach den ggf. abgebrochnen Schalter aus :-)

    Schauen wir mal wohin die Reise im 3D Drucker Bereich geht. Wie ich letztens gelesen habe im Blog

    gibt es sogar die Möglichkeit 3D Drucker im Medizin Bereich zu nutzen!

    Das bietet wirklich tolle, sinnvolle und vor allem hilfreiche Möglichkeiten!

    Gruß
    Andre
