Fillamentum Fillamentum Natural NonOilen Biodegradable Filament - 1.75mm (.75kg)

I have been delving into recycled, biodegradable, and compostable 3D printing filaments. From my viewpoint is it still is the typical conditions of industrial composting that PLA is certified for. So, under those conditions 3 times faster. But not home compost, etc...

Looking at the official site, it is compostable at home with an elecric composter (note they say you will have better luck with breaking it into smaller parts) or you can send it to nonoilen to recycle/compost it.

everything has pores. From a study that has been done in the eu on printed parts and safety.
Bacterial Growth and Cleaning: Bacteria associated with food poisoning typically measure between 2-5 microns in length and 0.5-1.5 microns in diameter. While 3D-printed parts have tiny imperfections averaging 1 micron, warm soapy water was found to reduce bacterial colonies by 90%. This level of sanitation is considered sufficient for general food safety, though not necessarily meeting surgical cleanliness standards.

Lead Contamination in Nozzles: Standard 0.4 mm brass nozzles contain about 1.5% lead by weight, equating to 0.045 grams of lead for a 3-gram nozzle, with approximately 0.007 grams potentially contacting the filament. Before reaching 1,000 hours of operation, the amount of lead transferred is so minimal it cannot be measured, indicating a negligible level of contamination. Moreover, when the nozzle is not in use, an insignificant amount of lead leaches out, further minimizing potential exposure. By comparison, the average consumer is exposed to 19 times more lead from handling brass keys, highlighting how minimal the lead transfer from 3D printing nozzles truly is.

FDA Cleaning Standards: To achieve food-safe conditions, the FDA mandates a bleach solution of 200 ppm for at least one minute. This can be prepared by mixing 1 tablespoon of bleach with one gallon of water. Room temperature is recommended as warm water can deactivate bleach, while a two-minute soak maximizes sanitization.

Comparison with Household Items: Similar to 3D-printed parts, common kitchen items also have micron-sized pits and imperfections that can harbor bacteria. The study compared 3D-printed parts sanitized with soapy water to kitchen items, finding reductions in CFU ranging from 80% for plastic cutting boards to 99% for glass plates. This shows that 3D-printed parts, once cleaned, can be as safe as or safer than household items, which also contain pits and grooves capable of bacterial growth.
