ABS

Introduction

ABS (here) stands for Acrylonitrile butadiene styrene. It is a kind of plastic. For example, car parts and Legos are made from ABS

ABS in 3D printing

ABS comes in variants. It “is a copolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15 to 35% acrylonitrile, 5 to 30% butadiene and 40 to 60% styrene.” (Wikipedia)

Proportions + color pigments added will modify melting temperature and other behavior !

This implies that recommendations for your 3D printer only apply to the kind of ABS that was sold by the company (official recommendations) or that was bought by users (blogs, forums, wikis).

Health risks

• ABS fumes can be harmful. E.g. read Brent Stephens, Parham Azimi, Zeineb El Orch, Tiffanie Ramos, Ultrafine Particle Emissions from Desktop 3D Printers, Atmospheric Environment, Available online 6 July 2013, ISSN 1352-2310, http://dx.doi.org/10.1016/j.atmosenv.2013.06.050. (http://www.sciencedirect.com/science/article/pii/S1352231013005086)
• If you print in a small office, consider at least opening windows, even if that will lower print quality. Else, go for PLA which is much less harmful.
