Ensuring Food Safety with 3Dponics
Many individuals have expressed concerns about the safety of 3D-printed parts used in our hydroponics systems. We understand these concerns and want to assure you that 3Dponics parts are safe for use around food.
The Material We Use: PLA
At 3Dponics, we utilize PLA (polylactide or polylactic acid), a non-toxic, plant-based material. The FDA has classified PLA as Generally Recognized as Safe (GRAS), making it an ideal choice for food-related applications.
Why Choose PLA?
- Non-toxic: Safe for food contact.
- Plant-based: Derived from renewable resources such as corn, wheat, tapioca, and sugarcane.
- FDA Approved: Recognized as safe for food packaging and contact.
The Risks of ABS
In contrast to PLA, ABS (acrylonitrile butadiene styrene) is a petroleum-based plastic that poses potential health risks.
Key Differences: PLA vs. ABS
- Source: PLA is plant-based; ABS is petroleum-based.
- Toxicity: ABS contains harmful ingredients like butadiene and styrene.
- Safety: PLA is food-safe; ABS is not recommended for food contact.
For 3Dponics applications, it is crucial to avoid ABS and opt for PLA or other non-toxic, non-GMO filaments.
Scientific Validation of PLA’s Safety
A significant study conducted in 1995 evaluated PLA’s safety as a food-contact material. The findings, adhering to FDA guidelines, concluded:
- Limited Migration: The small amount of lactic acid released during use poses no significant risk.
- Safe Conversion: Migrating substances are expected to convert to lactic acid, a common and safe food ingredient.
Key Findings
- PLA releases a minimal amount of lactic acid into food.
- The estimated consumption from PLA is about 700 times less than that of a breast-fed infant.
Conclusion: Choose Wisely for Safety
You can confidently use PLA in your 3Dponics systems without worrying about food safety. Remember to:
- Stick to PLA or other eco-friendly, food-safe filaments.
- Avoid using ABS for any food-related applications.
