Chinese researchers investigate lemon juice gel as food material for 3D printing

The aim of this paper is to develop a new 3D printing food constructs based on lemon juice gel system. We investigated the effect of potato starch (10, 12.5, 15, 17.5 and 20 g/100 g) on the rheological properties and mechanical properties of lemon juice gels. Besides, the influence of printing parameters (nozzle height, nozzle diameter, extrusion rate and nozzle movement speed) on the quality of printed products were also studied. The results show that it is suitable to make the size of the nozzle height the same with that of the nozzle diameter, which could not be regarded as a key factor that affects print quality. An equation is proposed to explain the relationship between extrusion rate, nozzle diameter and nozzle movement speed. In this printing system, the 1 mm nozzle diameter, 24 mm3/s extrusion rate and 30 mm/s nozzle movement speed were found to be the optimal parameters to print 3D constructs matching the target geometry with fine resolution, more smooth surface texture, and fewer point defects with no compressed deformation.

3D bioprinting to be tested in agricultural research

3D bioprinting to be tested in agricultural research

Imitating nature in laboratories and manufacturing leaves, seeds, and even more complex structures of plants, animals or microorganisms could soon become a reality at Embrapa Genetic Resources and Biotechnology’s Laboratory of Nanobiotechnology (LNANO), in Brasília, DF, Brazil. The recent approval of a project, as well as other related activities, will enable researchers to test biological activities in three-dimensional environments, that is, closer to reality.

The project leader, the Embrapa researcher Luciano Paolino da Silva explains that the  technique used is called 3D bioprinting, a variant of 3D printing, a method to manufacture solid objects from a digital file containing spatial information and dimensional coordinates. The team intends to use the 3D bioprinting technology to create valid models and to test nanomaterials produced from biomolecules obtained from agricultural and forestry industry waste.  Continue reading “3D bioprinting to be tested in agricultural research”

Customised snacks through 3D food printing, developed by Finnish VTT

Customised snacks through 3D food printing, developed by Finnish VTT

VTT Technical Research Centre of Finland Ltd aims to develop advanced food manufacturing technologies by combining expertise in food, material science and 3D printing technology. Healthy snacks with great textures are in increasing demand among consumers. Researchers have the long-term vision of developing high-tech vending machines that provide customised purchases.

Today’s consumer expects healthy, nutritious food with added elements such as design, pleasure and even playfulness. Self-production would enable customisation in addition to these. 3D printing technology offers new opportunities to realise such expectations.

Recipe design & software to be grocer’s new secret sauce?

Recipe design

Recipe design & software to be grocer’s new secret sauce? 3D printing might bring tech world business model elements to grocery stores, such as software-as-a-service or SaaS. SaaS sells or licenses and delivers software to the user on demand rather than as a product in a box. In the future, grocery stores might compete on how their chefs, or store’s ‘food designers’, produce the best meal programs available only on that store’s website for single downloads and only using that store’s supplies.  Continue reading “Recipe design & software to be grocer’s new secret sauce?”

3D Food Printing Will Bring Complete Realignment of the Supply Chain

Numerous sectors are experimenting with 3D printing, which has the potential to disrupt many markets. One that’s already making progress is the food industry.

The U.S. Army hopes to use 3D printers to customize food for each soldier. NASA is exploring 3D printing of food in space. The technology could eventually even end hunger around the world.

What does that have to do with your supply chain? Quite a bit — because 3D printing does more than just revolutionize the production process. It also requires a complete realignment of the supply chain. Continue reading “3D Food Printing Will Bring Complete Realignment of the Supply Chain”

3D Model Printing for Pizza, Presented by Asian Company

The 3D printing revolution is taking about as long to happen as the process of 3D printing itself. The evolution from firing ink onto paper to printing three dimensional shapes is a slow-burn development as technology gradually gets better and prices creep down, but it will eventually change the world: consumerism, architecture, medicine… 3D printing will shake up many industries. Should China, the world’s biggest manufacturing country, be concerned? Maybe. Should Pizza Hut be scared? Absolutely. Continue reading “3D Model Printing for Pizza, Presented by Asian Company”

Carbon3D introduces CLIP, breakthrough technology for layerless 3D printing

Carbon3D today emerged from stealth on the main stage of the TED conference with an innovative approach to polymer-based 3D printing that promises to advance the industry beyond basic prototyping to 3D manufacturing. The new Continuous Liquid Interface Production technology (CLIP) harnesses light and oxygen to continuously grow objects… Continue reading “Carbon3D introduces CLIP, breakthrough technology for layerless 3D printing”
