I've been printing with PLA because it's 'plant based' and 'compostable'. However I read research that found PLA released the most of chemicals with EA (estrogenic activity) of all plastics tested!
On the other hand, another study found that PETG did not release any EA chemicals:


"Ten unstressed or stressed glycol-modified polyethylene terephthalate (PETG), cyclic olefin polymer (COP) or copolymer (COC) thermoplastic resins did not release chemicals with detectable EA under any test condition."

PETG not releasing EA chemicals is a big plus for me when printing gadgets for kids, however I wonder if I'm missing any information about PETG like I did with PLA?
