Zebrafish embryos that were exposed to 3-D printed discs (above) -- from FDM and STL devices -- suffered developmental problems. Those exposed to STL-printed discs treated with UV light showed fewer defects.
3-D printed parts from some commercial devices toxic to zebrafish embryos
The recent boom in 3-D printing has driven innovations in fields as disparate as haute couture and medical implants. But little is known about the safety of the materials used. In a new study in ACS' journal Environmental Science & Technology Letters, scientists showed that some 3-D printed parts are highly toxic to zebrafish embryos. Their findings could have implications not only for aquatic life but also for hobbyists, manufacturers and patients.
