3D Printing and Food Safety - PLA vs. ABS

The truth about 3D printing and food safety: PLA vs. ABS. 3Dponics is made with PLA, a non-toxic, plant-based material, so it is safe for use around food!

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.
