Is 3D Printing Food Safe? Everything You Need to Know About Our Coffee Accessories

Ensuring the Safety of Our 3D-Printed Coffee Accessories at Cafistiq

At Cafistiq, we prioritize the quality and safety of our products, especially those that come into contact with your coffee beans. We understand the concerns surrounding the food safety of 3D-printed items, and we aim to address them with full transparency.

Understanding Food Safety in 3D Printing

3D printing opens up incredible possibilities for creating unique and functional accessories. However, when it comes to products that interact with food, several considerations are essential:

  1. Microplastics in 3D-Printed Products: The layer-by-layer construction of 3D printing may result in microscopic particles loosening over time. While the risk is low, it is a factor to consider.

  2. Bacterial Growth in Layer Lines: Even with high-quality printing, fine crevices between layers can trap moisture, creating an environment for bacteria if the product is not thoroughly dried after washing.

  3. Lead Contamination from Brass Nozzles: Traditional brass nozzles used in 3D printers can release trace amounts of lead. While the risk is negligible, it is something we have proactively addressed.

Our Commitment to Safety

At Cafistiq, we have taken several steps to address these concerns and ensure the safety and quality of our 3D-printed products:

  1. Use of Stainless Steel Nozzles: All our printers are equipped with stainless steel nozzles, entirely eliminating any chance of lead contamination.

  2. Top-Quality Printing Equipment: We use industry-leading Bambu Lab printers, which are thoroughly cleaned and maintained to provide a pristine production environment.

  3. Food-Grade Filaments: We only use food-grade PLA and PETG materials, carefully selected to be free from harmful additives and colorants.

  4. Advanced Printing Techniques: We employ high-quality printing methods, including an ironing feature, which smooths the surface of each layer to minimize potential crevices.

  5. Post-Printing Heat Treatment: Each product undergoes a controlled heat treatment to remove any residual microplastic strands, ensuring a clean and smooth finish.

Cleaning and Intended Use

Our products are fully washable and can be cleaned using water and mild detergent. However, to maintain their quality and safety, please follow these guidelines:

  1. Dry Products Only: Our accessories are specifically designed for use with dry products such as whole coffee beans. They are not suitable for use with liquids like milk, oils, or other wet food products.

  2. After Washing: If you wash the parts, ensure they are thoroughly dried before use. Any residual moisture can increase the risk of bacterial growth in the natural layer lines of the 3D-printed product.

  3. Avoid Prolonged Liquid Contact: While the materials are safe for cleaning, prolonged exposure to liquids (e.g., using the product directly with milk or water) is not recommended as it may compromise the longevity and integrity of the product.

 

Why We Recommend Against Liquid Use

Even with our careful selection of food-grade materials and high-quality manufacturing processes, the layered structure of 3D-printed items makes them inherently less suited for extended contact with liquids. Using our accessories with liquids like milk or oils may lead to moisture getting trapped in micro crevices, which is difficult to eliminate entirely, even with careful cleaning.

For this reason, we highly recommend using our products exclusively with dry items, such as whole coffee beans. This ensures both the safety of the product and its longevity.

Conclusion

At Cafistiq, we are deeply committed to providing safe, reliable, and high-quality coffee accessories. While our products are washable and made from food-grade materials, they are best suited for use with dry products like whole coffee beans. Washing and drying them thoroughly after each use ensures they remain safe and hygienic.

If you are concerned about the potential risks of 3D-printed products or require accessories explicitly designed for wet products, we recommend exploring alternative options for your peace of mind.

Thank you for trusting Cafistiq. Your satisfaction drives our dedication to excellence, and we are here to answer any further questions you may have.
