In this week’s video we present the second part of our awesome memories, from the 3d food printing workshop at Fabcon 3D.
We just arrived to Messe Erfurt. First we discovered that the kitchen was empty and they had yet to build the sink and bring in all the equipment. But we also discovered that the organizers work fast! While we wait for things to come together, we went to do some shopping and get something to eat.
After that we set up the whole kitchen with a central table for up to 10 students. After that we dedicated the rest of the day to rehearse the workshop and too test the recipes and play with lots and lots of dry ice!
Of course we also had our epic high five moment with 3 hands!!
Aram and Jason you rock!!!
By the way if you have not seen the previous video you can watch it here.
Let us know if you wanna have fun too in one of workshops. Thank you
With his contribution we have started walking through the generative design path for 3DFP. His work was focused on designing an interface that was intuitive and easy to use. Moreover capable of creating customized designs based on a simple date. All it takes to use it is to have a special date in mind, it then immediately creates a unique design for your special date. The design is unique for the date, this creates a intimate link between the designer (commensal) and the dish. A completely new personal dialogue with the dish we are about to eat.
From David Vilella about 3D Food for Special Dates:
My Experience in 3digitalcooks
Firstly i want to express my gratitude to Luis Rodríguez Alcalde and Jason Mosbrucker for introduce me the 3D food printing and to teach me the basic concepts in order to reach on my second App called “3D FOOD for special dates”. Also i want to remark how they had managed my learning process with very clear and simple examples. Moreover they left me the liberty to contribute with my own ideas to design and to build this App.
Since this, let me introduce the main reason for 3DFOODforspecialdates: Everyone remembers the date of something special: birthday, anniversary, the day you met that someone special, the first kiss… people want to celebrate them with special details.
Finally i want to say that i admire their enterprising initiative, and i wish them good luck on their lots of projects. All my work and learning process in 3digitalcooks is shared in my github repository and in a google drive file.
David thank you very very much for all the effort and endless nights working with us. Getting to understand the amazing world of 3DFP! 3DC will be always your home we wish you the greatest best with your new adventures!!!
Most 3d printers use the same approach to print food, building layer after layer. Does that make sense? Probably most of the time, but definitely is not the only approach.
An this is how Yogurt Up was born. Actually not. Yogurt up was born by looking at a food without caring about how to 3d print it. Everything started during my last visit to Korea, I was having dinner and my mother in law hand me a greek yogurt. Is funny how things that are so obvious some times are overlooked. After the first two spoons I realized that the texture of it was good to 3d print. And start playing with it. A week later when I was back to San Francisco and I bought 5 different types of yogurt and start experimenting with it.
Not all of them have the same consistency, obviously but I finally settle for Fage greek yogurt (we are not sponsored by them but would be cool 😉 ). The first test printing yogurt was free hand, without the printer just the extruder. That helped to try different deposition techniques. That was the instant when the non continuous dot technique started to take form.
The idea is to extrude big dots as building blocks elements.
By hand was easy to try but in order to test prints with the printer (DUH), a basic tool was mandatory to explore the parameters needed to control the technique. This was the moment the the Yogurt Up design tool was born.
What is it?
This is a test design tool that created dotted pyramids. The following video is a great visual aid to understand what the app does.
How to use it?
You are going to need a 3d printer with paste extruder. I am using Pinya3.
General pyramid parameters:
Height where the initial layer of dots will be be printed.
The distance between the bases of the previous layer of dots and the current one.
Printer head movement feedrate without printing.
Distance to retract the printer in the Z axis between travel from dot to dot.
Initial reservoir build up pressure to start printing with a paste extruder.
Release reservoir pressure to avoid oozing material.
This is the amount of rows and columns that the base pyramid layer will have. In previous video it was 3.
Distance between the center of each adjacent dot.
Distance between the dots layer base height and the starting dot printing height.
Final dot printing height refered to the current layer of dots.
Printing dot feedrate. Affects both the extrusion and Z axis.
Dot extrusion [mm]
Distance to be extruded per dot.
Extruder retraction after each printed dot to avoid oozing/dripping material.
This is a test application, by no means I guarantee will work with your printer, therefore use it AS IS.
The output GCode start at the position x=0 and y=0.
We have tried, several different material; yogurt, chocolate mousse, hummus,… So extruding feedrate will totally depend on the material and the extruder that you are using. Actually fast prints will depend on that.
Obviously this app is open source, here is the repository just in case you want to experiment and learn from it.
Collabos are great. Collabos with great people are DOUBLE great! This is the story behind the first day sharing printing and ceramics ideas with the folks from Bussoga.
Printed porcelain decoration
Disclaimer. IF you do not know who Bussoga is, they are the masterminds behind all the awesome tiles that we have been using as dishes for the pasts few months.
You might seen the pictures from the roadtrip, here is how our workspace look right before starting our day. Bussoga‘s HQ are awesome!!!
Our first goal was to set up the printer, after some minor issues (losing our end-effector at the train station) we were all set to start the tests.
During the day mainly we tested two types of materials. White clay and porcelain. Probably the coolest lesson learned during the day was how to start working to get the right consistency for each one of them (still lots to learn yet, but gotta start somewhere :)). Also how to link consistencies with the printing parameters (speeds, nozzle sizes, designs,…).
Here you can see Josep from Bussoga getting the porcelain mix right. It took us a couple of attempts to get the “right” consistency. Porcelain allowed to use small nozzle diameter (1.5mm) but without a hard consistency we could get tall prints.
Josep mixing porcelain
This design is from Irina from Bussoga and it is our favourite print of the day. Worth to say it was painfully designed with Curv3s (undo feature request, still pending to implement).
Printed girl face
During all day we jumped from porcelain to clay several times. Clay happened to be a harder horse to tame. Through each try (wetting it more) we tested lots of different configurations: speeds, pressures and nozzles. One of my favourite was the ultra big 12mm nozzle prints looks just cute.
Printing clay at big with big nozzle
Closer look the big nozzle prints.
Printed thick layer pots
After some trial and error we got a thinner clay that could be extruded with a 3 to 4mm nozzle. Was hard to get the right consistency. The day was arriving to the end but we managed to print a few attempts.
3d printed cup test
Overall it was a fantastic experience, that we are sure is going to drive into tons of ideas (it is already) and hopefully some more upcoming cool projects?
