Styrene is a monomer made of carbon and hydrogen atoms.
Styrene is a monomer made of carbon and hydrogen atoms.
Styrene is itself made of multiple parts. The hexagon ring (6 carbon) is known as "benzene." The 2 carbon chain is known as "ethylene". Styrene synonyms include "Ethenylbenzene".

Styrofoam is the official name of DuPont's polystyrene blend. When smaller beads of styrene are exposed to steam, they expand, polymerize, and trap gasses in the "foam." This creates the cushioned material we know as Styrofoam.

When Styrene is polymerized with Acrylonitrile and 1,3-butadiene, it forms Acrylonitrile Butadiene Styrene (ABS). ABS is used in lots of materials, including Lego bricks.
While ABS is a great material for building small plastics, toxic fumes that include styrene can come from 3D printers using ABS.

"Styrene and the primary metabolite styrene-7,8-oxide are genotoxic and carcinogenic. Long-term chemical carcinogenesis bioassays showed that styrene caused lung cancers in several strains of mice and mammary cancers in rats and styrene-7,8-oxide caused tumours of the forestomach in rats and mice and of the liver in mice" (Huff, 2011).

3D Printing of ABS products (like these Legos) can release substantial amounts of styrene.
Styrene is metabolized into Styrene oxide in the body, which can lead to DNA damage and cancer
While some specially marked polystyrene can be microwaved (polystyrene #6) most styrofoam will leech dangerous styrene into your food at high temps.
DO NOT MICROWAVE YOUR CUP OF NOODLES!
While ABS is an excellent 3D printing material, we are forced to use alternatives in the classroom because of the dangers of styrene

Polylactic Acid (PLA) is the most common 3D printing filament. Lactic acid is produced in our muscles, so it has minimal biological dangers.

Almost all spools of filament can be purchased online for a modest cost. Each filament has unique properties in tensile strength, resistance to oxidation and water, and melting temperature that make each useful for different applications.

PET
Polyethylene terephthalate (PET) is one of the most common thermo-plastics. The C-O-C bond between monomers of PET is known as an "ester", so it is also a "polyester".

Nylon
Nylon
Nylon is strong and impact resistant, but does not polymerize well in the presence of water. Humidity prevents effective Nylon 3D printing in many environments.
