A Comprehensive Guide of Food Safe 3D Printer Filament

The world of 3D printing has witnessed transformative advancements, becoming a staple in various industries. From sculpting intricate designs to streamlining manufacturing processes, the sky’s the limit. Among its diverse applications, food safe 3D printer filament stands out as particularly intriguing. 

This article endeavors to shine a spotlight on these special filaments, ensuring that both newcomers and 3D printing veterans can create items safe for food interaction. With increasing interest in at home printing, understanding these materials has never been more crucial.

Why is Food Safe 3D Printer Filament Important?

As 3D printing integrates into our kitchens and dining experiences, concerns over material safety are paramount. When 3D printed items are used as utensils or containers, there’s a potential risk of chemical leaching. This is why the filament used becomes a matter of utmost importance. Ensuring that these materials are food safe prevents unwanted chemical transfer, preserving not only the flavor but also the well being of users. As consumers become more health conscious, businesses and hobbyists must prioritize safety in their 3D printed creations.

Key Characteristics of Food Safe 3D Printer Filaments

To the untrained eye, all 3D printing materials might seem alike. However, certain attributes distinguish a food safe filament from its counterparts:

FDA Compliance: The mark of true food safety for many is FDA compliance. Filaments that adhere to these regulations have undergone meticulous testing and have met stringent safety criteria. This means they have been deemed suitable and secure for food contact. The FDA seal is a reassuring indication for many consumers and professionals.

No Harmful Additives: While many filaments are designed for durability or flexibility, food safe 3D filament has a specific emphasis on health. It is typically devoid of harmful additives or toxins that might migrate into food. This purity ensures that users can enjoy their food without underlying concerns about contamination.

Smooth Surfaces: Surfaces that are porous or rough can become breeding grounds for bacteria. Therefore, 3D printed objects intended for food must have smooth finishes. This not only aids in cleaning but also significantly reduces the risk of foodborne illnesses.

Given the growing interest in food-safe printing, numerous filaments have emerged as favorites among the printing community:

PET (Polyethylene Terephthalate): PET, beyond its clarity and strength, is revered for its safety profile. Often seen in the food packaging sector, its transition into the 3D printing space has been welcomed by many. As a food grade 3D filament, it is a reliable choice for those prioritizing both aesthetics and safety.

PLA (Polylactic Acid): PLA’s eco-friendly origin, derived from resources like corn starch or sugarcane, makes it a popular choice. Additionally, its biodegradable nature and potential as a food safe filament have contributed to its growing fan base in the 3D printing community.

PP (Polypropylene): PP is renowned for its resilience. Its high flexibility and fatigue resistance make it a go-to for many applications, including the production of reusable food containers. As a filament, its safety and durability harmoniously blend, making it an optimal choice.

Best Brands Offering Food Safe Filament

As the demand grows, several brands have risen to the challenge by ensuring top-notch food safe 3D printer filament offerings:

Polymaker: Polymaker, an industry leader, offers more than just filament. Their commitment to quality is evident in their PolyLite and PolyMax series, which meld safety with unparalleled durability.

ColorFabb: A trusted name in the industry, ColorFabb ensures its offerings like XT and nGen are not only top-quality but also FDA compliant. This dual focus has made them a favorite among professionals and hobbyists.

Formlabs: While Formlabs might be recognized for its broader 3D printing solutions, its dedication to safety is commendable. Their Dental SG and Dental LT Resins, despite being primarily for dental applications, align with biocompatibility standards apt for food contact.

Safety Precautions for Using Food Safe 3D Printer Filament

While the filament is essential, the 3D printing process itself can introduce a myriad of safety concerns:

Maintain a Clean Printer: A printer’s cleanliness can often be overlooked, yet it’s crucial. Regular cleaning can fend off potential bacterial growth and prevent contaminants from sullying the final product. A well-maintained printer is the first line of defense against contamination.

Post-process Prints: The post-printing phase is equally pivotal. Processes such as sanding or coating can refine the 3D printed object, ensuring a smooth and safe surface. These additional steps, though time-consuming, are vital in achieving optimal safety.

Avoid Cross-contamination: The versatility of 3D printers is a double-edged sword. If a printer oscillates between food grade filament and non-food-safe materials, contamination risks soar. A dedicated printer for food-related items, while an investment, can mitigate these concerns.


The convergence of 3D printing and culinary worlds is an exciting frontier, promising innovation and creativity. However, with great potential comes great responsibility. As brands, hobbyists, and industries explore food safe 3D filament, vigilance and knowledge become paramount. With the right materials and best practices, the future of food safe 3D printing looks not only promising but also appetizing. Safe printing practices today lay the foundation for a healthier, more innovative tomorrow.
