ABS in 3D printing

New page

== Introduction ==

ABS (here) stands for '''Acrylonitrile butadiene styrene'''. It is a kind of plastic. For example, car parts and Legos are made from ABS. This article describes its use as [[3D printer filament]]

See also:
* [[PLA]], the other popular polymer for 3D printing
* [[3D printing]] and other articles in the [[:Category:3D printing|3D printing]] category

== ABS in 3D printing ==

ABS comes in variants. It {{quotation|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.}} ([http://en.wikipedia.org/wiki/Acrylonitrile_butadiene_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).

=== Tips ===

ABS doesn't stick well to common platforms (glass, kapton tape, plastics) and more importantly, larger and high objects will warp.

When I print ABS with my printer that is rather designed for PLA printing (a FelixPrinter):
* A use a raft. If you also use glue, then make sure that the raft not 100% dense, or you won't be able to remove the part.
* Pritt Power stick glue.

To remove a print that sticks to well (e.g. something with a flat bottom), there a several strategies, for example:
* soak the bed in warm water (if you can easily remove the bed)
* Heat the platform to at least 65 degrees and pour water over it (only works if there is space within the raft)
* Use dental floss (tie it around)
* Use some thin scraper (And extreme solution is http://www.thingiverse.com/thing:19029).

Using pliers is dangerous, it may damage the print, the surface of the platform, platform alignment etc.

I rather print ABS in a corner of the platform, so that the remining glue won't inhibit me from getting PLA prints of the platform. It probably would be best to add a plate on top of the platform, but that requires recalibrating :(

=== 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.
