In this article, we will describe the main elements that enable the use of food safe 3d printed parts in most application and how we can support you in this :
Picture this: a food production line that seamlessly integrates customized, food-safe components meticulously crafted through 3D printing. In a world where precision and safety are paramount, food-safe 3D printing is revolutionizing the food industry. This advanced technology offers unparalleled versatility, enabling food companies to create bespoke solutions while adhering to stringent health and safety standards.
In this article, we will explore the essentials of food-safe 3D printing, providing food industry professionals with comprehensive insights into its applications, benefits, and critical considerations. You will learn about the key aspects of ensuring food safety, the materials and processes involved, and practical tips for successful implementation. Join us on this informative journey to discover how food-safe 3D printing can elevate your operations to new heights of excellence and innovation.
The advent of 3D printing technology has had a profound impact on various industries, and the food sector is no exception. Food-safe 3D printing enables the creation of customized tools, molds, endless screws, and even food products with incredible precision. This technology offers a level of flexibility that traditional manufacturing methods simply cannot match.
The ability to produce intricate designs and unique shapes opens up a world of possibilities for food companies looking to innovate and stand out in the competitive market. Additionally, 3D printing allows for rapid prototyping and reduces lead times, enabling faster product development and market entry.
However, as with any emerging technology, there are important considerations to keep in mind, particularly when it comes to food safety. Ensuring that 3D-printed components are safe for food contact is paramount, and this requires a thorough understanding of the materials, processes, and regulations involved.
Food-safe 3D printing involves the use of materials and processes that are specifically designed to be safe for contact with food. This means that the printed objects must not leach harmful chemicals or substances into the food, and they must be able to withstand the rigors of food processing environments. One specificity of 3d printing is that primarily due to the layer-by-layer construction method inherent to the process, this technique often results in tiny crevices and cavities between layers, which can become prime breeding grounds for microbes and bacteria. Consequently, to ensure food safety in your application, several key factors must be considered:
Materials used in food-safe 3D printing need to be approved by relevant regulatory bodies such as the Food and Drug Administration (FDA) in the United States or the European Food Safety Authority (EFSA) in Europe. (article 3 of Regulation (EC) No 1935/2004). These materials must be free from harmful chemicals and additives that could pose a risk to consumers.
If a given material could be a good fit for use in a food safe environment, not all of them would be systematically available depending on the technology that you would be planning to use. If in the metal range, stainless steel stands as the almost inevitable choice, here are some of the commonly used plastic materials for food-safe 3D printing :
You might consider using a non-food safe material with a food-safe coating; however, this approach comes with its own set of limitations.When using food-safe coatings on plastic, two significant drawbacks need careful consideration: the imperfect application of the coating and potential scratches during use. An uneven or flawed application can leave areas of the plastic exposed, undermining the intended safety by allowing chemical leaking into food. Additionally, daily use can cause scratches that penetrate the coating, further exposing the underlying plastic and compromising its food-safe properties. These vulnerabilities highlight the importance of selecting materials that maintain their safety and integrity over time.
It is essential to verify that the chosen materials comply with the relevant food safety regulations in your region. This may involve obtaining certification from regulatory authorities and conducting thorough testing to ensure that the materials meet the required standards.
In addition to selecting the right materials, the processing of the 3D-printed components plays a crucial role in ensuring food safety. Proper processing techniques are necessary to prevent contamination and ensure that the printed objects are free from defects.
To produce food-safe 3D-printed components, the manufacturer must follow strict processing guidelines that address factors such as temperature control, cleanliness, and contamination prevention. This includes maintaining a clean production environment and using food-grade equipment. In practice, in the context of european users, it means that the part manufacturer should comply with Commission Regulation (EC) No 2023/2006 of 22 December 2006 on good manufacturing practice for materials and articles intended to come into contact with food.
Post-processing is a vital step in ensuring the safety and quality of 3D-printed components. This may involve cleaning, smoothing, and finishing the printed objects to remove any residual contaminants and achieve a smooth surface that is easy to clean.
Regular maintenance and inspection of each 3D printer is essential to ensure consistent quality and prevent any potential issues that could compromise food safety. This includes routine cleaning, calibration, and monitoring of the printing process.

The adoption of food-safe 3D printing offers several benefits for food companies, including increased efficiency, reduced costs, and enhanced product quality.
3D printing simplifies the production process, reducing the need for complex tooling and machinery. This leads to faster production times and increased efficiency, allowing food companies to meet demand more effectively.
By eliminating the need for expensive molds and tooling, 3D printing reduces production costs. This is particularly beneficial for small and medium-sized food companies that may have limited resources.
The precision and accuracy of 3D printing ensure that the final product meets high-quality standards. This results in consistent and reliable products that enhance customer satisfaction and brand reputation.
A great variety of food can actually be 3D printed, from pizza made by 3D printers from NASA, to chocolate, pasta and meat. With an adapted food 3D printer, any kind of food could be made with 3D printing.
Yes 3D printed food can be eaten. If the food used for the 3D printing process is edible, then the 3D printed product can totally be eaten.
