Researchers Design Robot That Can 3D Print a Cake With Up To Seven Ingredients (science.org) 55

sciencehabit shares a report from Science Magazine: Researchers have designed a robot that can create and cook a cake with up to seven ingredients, more than any other printed food to date. The scientists built their programmable patisserie by retrofitting a 3D printer with nozzles designed to squeeze out selected ingredients. They then programmed it to dispense those into layered cakes. Initial trials resulted in triangular gobs of sweet goo, so the researchers came up with a winning recipe that could hold its own. They nested softer ingredients, such as jelly and banana puree, inside of stiffer ingredients, such as peanut butter and Nutella, then reinforced those with hefty doses of graham cracker crust. Then, they broiled the crust with a laser and topped the cake with frosting and cherry glaze. The result? A cheesecake, of sorts.

Despite its novelty, the computer-guided cook may not be able to battle it out under the stern eye of a guest judge any time soon -- each slice took about 30 minutes to print. Further in the future, however, better printers could make some cooking automatic, freeing people from kitchen tasks they may find tiring or repetitive -- assuming you don't enjoy those things. A food printer could also be programmed to dispense meals with precision-controlled nutrient and calorie content, helping prepare food for those on strict diets.
The study has been published in the journal npj Science of Food.

      Speaking of time, I wonder if we'll actually call it an "improvement" when tens of thousands of professional bakers and cake decorators are made unemployable because the 1Click Instant Gratifi-Generation ain't got time for that, and doesn't care what made it as long as it's here by same-day delivery.

Even if we change it to "get training in a new, actually marketable, skill" and presume that there are trade schools available that can do a sufficient job of this without any political indoctrination thrown in, I am willing to speculate that this answer will only be sufficient temporarily at best.

                Given the sheer unrelenting demand to support WFH, I tend to doubt that. Workers seem to have no problem whatsoever working in their homes and not being SEEN.

              100% correct. We will eventually all become unemployable. I see the only way humans might sustain any semblance of "work" is through an avatar that can perform the same as the machines taking jobs. And quite frankly, labeling the need to work and contribute to society with a job is far from an outdated moral argument. It's ingrained in our very psyche. Has been for our entire existence. It's why even millionaires can get depressed when they quit working.

              Automation could mean freedom, you're correct.

              • What I am really interested in knowing is what actions you think we should be taking right now in response to the ongoing successes in automating labor?

                Are you advocating that we should halt these efforts in order to prevent people from becoming unemployable?
                Or are you (like me) advocating that we should continue such efforts because labor-automation is ultimately liberating?
                Or are you advocating for something else entirely?
                Or are you simply complaining about the problem without suggesting any practical sol

                • I've already provided an answer. I see the only way humans might sustain any semblance of "work" is through an avatar that can perform the same as the machines taking jobs. That's it in a nutshell. While you speak of automation being liberating, it's going to take quite a bit more than that in order to convince the non-working generation. We humans struggle enough to understand our very existence without that additional pressure of feeling basically pointless in the world.

      Unlike cooking, baking is a rather exact science. As in something a machine would be ideal at creating. You don't just wing a souffle. Critics soon won't be able to tell the difference, which will eventually lead to them not caring what made it, as long as it's delicious. Which it will be.

      "Typical" isn't the reason we're here talking about robots baking cakes. It's called The Future, and it's coming faster than ever before.

      I am not so sure. If you look at food preparation as a hobby or profession its actually always been pretty quick to embrace technology.

      Examples - Baking was pretty much revolutionized with refrigeration becoming available. While things like pastry pre-existed, they were largely out of reach for the home cook, not having ice delivered etc. Once everyone had a freezer, lots more pastry recipes came on the scene, and chilled doughs became common and absolutely transformed the presentation and textures for al

Think about all the different baking techniques that are used to create different mouthfeels and distributions of flavor. This machine could, if properly advanced, not just replicate some of them but exceed them in areas. Think a thin pastry dome with a perfect latticework interior and a single drop of a

    • A robot is much too mundane for your typical pedantic food critic.

      I don't know if you ever watch Iron Chef America, but I do. Some of the judges are well-known food critics, and it's not uncommon for one of them to say, "I never would have thought that a combination of X and Y could possibly be palatable, but it actually works! You've made a believer out of me. That's because it's their job to be objective and judge the dishes on how they taste, not how the judges expected them to taste.

    Is the resulting cake worth eating? Any 3D printer that can handle seven ingredients, should be able to do this. The issue is not whether you can make something with 3D printing, but whether the resulting item is useful or better than what you can make by other means.
    • you pour batter into a pan, the batter is best made by a chemist (seriously, I saw a video about cake mixes and the best bakers in the world can't make from scratch what Duncan Hines & Betty Crocker's chemists can) so I'm guessing it tastes fine.

      • You're both right and wrong. It's not that you need to be a chemist to bake the best cake, but that you have to measure everything as accurately as a chemist would, because to a large extent, baking is a form of chemistry. Unlike the average home baker, a professional baker (and I spent several years working in bakeries) measures all dry ingredients by weight, not volume. Among other things, it means that you almost never need to sift flour because sifting doesn't change the weight/mass. This is even mo

        Was the video produced by Duncan Hines or Betty Crocker?

        Today's boxed cake mixes are reasonably good (I use them more often than not when I want to make a cake), but all you have to do is eat a cake made by a professional baker vs. one from a boxed mix to realize that the boxed mix certainly doesn't have the advantage.

  • The novelty here is twofold:
    1. Printing more solid materials around more liquid ones to contain them.
    2. Using lasers to "cook" at the specific location being printed as it prints (in this case the outer crust).

    The # of ingredients is also of note.

    The article also talks about being able to "layer taste", dropping certain ingredients in specific locations.

    But I can't help but think such a device will end up in the same realm as all of the "bread makers" out there? A lot of people bought one and used it, but ultimately? It didn't really contribute to any big change in the idea of buying fresh baked bread from a local bakery.

    • by Reziac ( 43301 ) *

      A 3D cake printer won't bet aimed at consumers. It'll be aimed at catering companies who land the contract by providing a uniquely interesting (to some marketing department) edible product. Same market as that $1200 3D-chocolate printer.

      Breadmakers don't have near enough market penetration to compete with commercial bakeries, and don't properly "proof" the dough to get that real bread flavor and texture; even so mine is right handy when I'm snowed in and run out of bread.

  • I'd try this just for the geek factor. It's a little like Dippin' Dots or cosmopolitan balls. Try it to say that you've tried it and then go back to the real thing.
    But while we're on the subject of cake, what the hell happened to cake? Everybody and their mother is making cake as an art piece but whatever happened to making them taste really good? I mean, seriously, a traditional yellow cake with a real butter cream filling and frosting and buttercream flowers made by hand can't be beat.

    • If you watch the various baking/decorating contests on TV, most of the judges give little more than lip service to the idea that a cake should taste good. Unless there's something drastically wrong, such as having the cake burnt, or raw in the middle, they don't seem to care much as long as the decorations look good. This is very much not true for any competition where Duff Goldman is a judge because he cares how the baked goods taste, and will mark down anything that isn't properly baked.
