When 3-D printers were first announced, I questioned how toxic the materials might be that are used to make the 3-D objects.
Now a new study shows that the materials are toxic to fish embryos and may be toxic to other animals [that would include humans]
This was discovered when a graduate student used a a 3-D printed, custom-shaped disk to help analyze zebra fish embryos in her lab. But there was no analysis because the material killed the baby fish very quickly.
The student and her advisor decided to text the toxicity of products made from two of the most popular 3-D printers currently available. One uses an unspecified melted plastic and the other an unspecified liquid resin that hardens when an ultraviolet light shines on it.
They found that both materials were “pretty acutely toxic,’ meaning that the fish embryos died soon after coming in contact with the material.
