3D food printing
Introduction
3D food printers can print food, usually through one more syringes. Food 3D printers actually were invented around the same time as low cost filament printers, but did not have much success. The first known open source printers capable of printing food were probably developed at Cornell University around 2005 under the name of fablab@home by Hod Lipson [1] and collaborators.
As of 2017 however, there is renewed interest. 3D food printing can server two purposes according to 3D Food Printing: It can be healthy and good for the environment because it can help to convert alternative ingredients such as proteins from algae, beet leaves, or insects into tasty products. It also opens the door to food customization and therefore tune up with individual needs and preferences.
According to Sun et al (2015),[2] “Three-dimensional (3D) Food Printing, also known as Food Layered Manufacture (Wegrzyn et al. 2012), can be one of the potential ways to bridge this gap. It is a digitally controlled, robotic construction process which can build up complex 3D food products layer by layer (Huang et al. 2013). It has started a revolution in cooking by precisely mixing, depositing, and cooking layers of ingredients, so that users can easily and rapidly experiment with different material combinations. With this technology, food can be designed and fabricated to meet individual needs on health condition and physical activities through controlling the amount of printing material and nutrition content.”

Technology
Most 3D food printers adopt some kind of additive filament deposition technology, e.g. they work like most 3D hobby printers, except that the plastic filament is replaced by syringue that are filled with some paste.
According to 2007 - 2017: 10 years of 3D chocolate printing (retrieved Feb 2017), ChocALM (2007) from Exeter University was maybe the The World's First 3-D Chocolate Printer. The first model was commercialized in 2012 as Choc Creator V.1. As of 2017 Choc Creator V.20 plus is sold by Choc Edge.
Technical specifications of the Choc Creator V2.0:
- The printer uses STL files for Additive Layer Manufactoring. The chocolate must be tempered first and then loaded into a specially designed syringe.
- Build envelope: 180x180x50mm
- Printhead: Refillable 30ml metal syringe with detachable nozzle for easy cleaning
- Layer height: 0.4 – 1.5mm
- Nozzle size: either 0.4 or 0.8 mm (the later is better for extended print time)
- Substrate: Stainless steel platform
- Material: Dark Belgian chocolate (Callebaut 811)
- Weight: 18kg
- Display interface: LCD touchscreen
- Software: Choc Art Studio
- Easy to use software: Android apps
- Price: about 2800 Euros + about 500 Euros for a tempering machine (but one also could use a micro oven)
Materials
Most popular materials seem to be chocolate or dough for cookies.
However, according to [2], “Alternative ingredients extracted from algae, fungi, seaweed, lupine, and insects are novel sources for protein and fiber. In the “Insects Au Gratin” project, insect powders mixed with extrudable icing and soft cheese were used as printing materials to shape food structures and make tasty pieces (Walters et al. 2011). Residues from the current agricultural and food processing can be transformed to biologically active metabolites, enzymes, and food flavor compounds (Silva et al. 2007; Nikitina et al. 2007), as sustainable and eco-friendly printing material sources.”. In other words, this technology does have potential to develop healthier food, improve environmental impact and help feed an ever growing population.
3D food printers in education
In general education there may be some potential for food 3D printing, e.g. for teaching design (and related soft skills), plus some technical skills.
