Hello everyone,


Lou DiBerardinis, my EHS Director, forwarded this thread to me

since I am responsible for the TSCA program at MIT.


No doubt we are going to see more on the risk science surrounding

3D printers.  From a TSCA perspective, coatings/inks/polymers/resin

are not  considered articles.  Whatever resin is used to produce an object

from a 3D printer is regulated under TSCA. 


A more interesting scenario would be if a naturally occurring resin

was somehow found to have applications in 3D printing and if that

naturally occurring resin turned out to have adverse human or environmental

health effects.  As I understand it, EPA provides some exclusions under

the TSCA inventory for a naturally occurring compound.


Also, under TSCA, “article” is defined in a very particular way.

It is implicit the object will not change form in its end use (and in theory

not release any material to the environment).   A metal pan would be

considered an article and not TSCA-regulated.  A metal pan coated with

Teflon would be TSCA-regulated the Teflon is a coating, is in and of

itself not an article and is not inextricably bound to the metal pan.


On another note… how do I go about subscribing to this listserv?


Thank you,

Here is an interesting TSCA issue - the product of the printer is an object and therefore wouldn't be a TSCA applicable item.  However, there was a similar issue with carbonless paper when it first came out and that was determined to be a chemical under TSCA.   So - let the discussion begin.
