3D Printed Food: All You Need to Know

Food might be one of the last things on your mind when it comes to 3D printing. But since the availability of 3D printers for homes has increased, so has people's interest in three-dimensional printing, which gave the bright idea of printing food.

From Oreos to cheesecake, the 3D printed food is surely making a big impression on the food industry. However, how does it taste? Is 3D printing the new big thing in the food industry? How does 3D printing food work? What foods can be 3D printed today? Aside from these questions, we must also address the benefits and limitations of 3D-printed food. We'll also know what types of 3D printers are used today in food printing.

What is 3D Printed Food? The concept of 3D printing food is much the same as your typical 3D printer, but of course, the main difference is that it extrudes edible filament. Moreover, you get multiple extruders depending on what type of food instead of the typical two extruders, like just putting icing on a cake using a piping cone.

A 3D-printed food also utilizes the 3-axis system. Your typical printer uses two dimensions that include x and y. 3D printers can read the z-axis and create a three-dimensional object. Thus, the 3d model is translated, and the extruders can build the three-dimensional object in layers, sometimes with supports to keep the object upright as it prints to complete the other parts. Other 3D-printed objects even have moving parts that can be remote-controlled. You may want to check these controlled airplanes that were 3D printed.

Aside from your syringe-like extruders, your 3D printing food will usually have these parts:

Mixing Chambers – Where food is blended or temporarily placed before being drawn into the extruder.

Hoppers – These are containers usually near and before your extrusion tube so they can hold more edible filaments or mixtures for an extended period. Thus, less need for refilling of food filaments on your extruder for larger food creations.

Conveyor Track – Similar to your 3D printer, 3D food printers need a conveyor belt or moving platform.

Coolers or Temperature Control Zones – These are usually computer-aided to adjust the temperature of filaments or built-in hoppers of a 3D printing food machine. Coolers for the 3D-printed food allow food to have a certain texture or consistency.

Computer – Used to bridge communication between the user and software.

Is 3D Printed Food the Future in the Food Industry? In 2016, the first restaurant to serve 3D-printed food, called Food Ink , opened its doors to intrigue customers in London, which shows that there's a lot of potential in the hospitality sector. Also, thanks to the 3D printing technology, space explorers are able to enjoy pizza, steak, and milkshakes. The healthcare industry also sees potential in 3D printing food, such as people with dysphagia or those who have trouble swallowing. With food 3D printers, you can create food that is easily swallowed but, at the same time, nutritious and conditioned for a patient's specific needs.

Though food that is 3D printed today is still enjoyed by most as an accompaniment to full meals, this advanced technology has the potential to become mainstream as it opens up a lot of possibilities. In addition, 3D-printed food also addresses many problems today.

How Does 3D-printed Food Taste Like? According to a former Michelin chef, Tom Jacobs, when interviewed in Built-in , the taste of 3D-printed food is just similar to your typical food. "You won't detect any difference in taste," as stated by Jacobs. However, 3D-printed food can improve or change food texture or pattern. So, for instance, chocolate filling can be made soft or hard depending on your textural needs.

Different Types of 3D Printed Food? 3D printing for culinary purposes brings customization, but while still in the earliest stage, the following are typical 3D-printed foods.

Dressings and sauces Cakes and Pastries Purees Gel-like constancy Cheese Ice Cream Chocolate Sugar What Are the Types of 3D Printers Used in Food Printing According to Mechanism: Syringe-based Extrusion Food Printer – Considered an open source of 3D printing food, it uses a motor mechanism that plunges down when powered and passes through the syringe to push down the edible food filament. Screw-type Extrusion – It also uses a motor mechanism, but this time uses a screw that runs through the extrusion tube, allowing the edible filament to pass through the extrusion nozzle. Air-pressure Driven Extrusion Food Printer – This type of 3D foot printer has the simplest mechanism and doesn't need a motor to operate; instead, it uses compressed air to push the edible filament down the extrusion nozzle.

According to the Type of Edible Food Filament Paste Extrusion – The food printer is mainly designed to extrude pasty food materials, ensuring a continuous flow of food on the plate, which makes it best for making tomato paste or purees. Inkjet-based Printing – best for intricate food types that need superfine extrusions. This is great for creating artwork or message texts on cakes or pastries. Layered Gel Printing – Layered gel printing is a great option when you need gel-like consistency. You can create gummy bear look-alike creations. CNC-based Food Printers – Utilize CNC technology or Computer Numerical Control to create precise shapes or carve out edible food. What are the Benefits of 3D Printing Food? Wider Range of Food Types The food revolution comes with the potential of having a range of food types that cater to specific needs.

Customization of Food The potential of having every meal that's tailor-made for your specific nutritional needs is likely possible in the future. In fact, elderly people now benefit from these edible 3D-printed foods. Advancements in 3D printing technology have enabled greater customization and personalization of printed food items. Chefs and food designers can create unique shapes, textures, and designs to suit individual preferences.

Opportunity for Intricate Designs Aside from nutritional value and texture, food presentations are improved, and impossible designs can be made easily, even without a professional chef.
