Additive Manufacturing Material ABS

Additive Manufacturing Material: ABS

ABS (acrylonitrile butadiene styrene) is a tough and strong material that has traditionally been difficult to 3D print but still has been used extensively in material extrusion. Used widely in desktop 3D printing and also on Stratasys systems ABS warps if the heated bed or heated chamber do not have enough temperature control. Printed at around 90 C bed temperature and 240 nozzle the material makes for tough parts. There has also been a worry in the 3D printing community specifically of ABS fumes and their possible effects. Good ventilation and an enclosed build chamber with a fume hood or similar is always suggested in 3D printing generally. With ABS in particular higher temperatures than 250 should be avoided as should fumes.

If dialed in and printed successfully, however, ABS significantly extends the functionality of desktop 3D printers when compared to PLA. Higher heat deflection and strength mean that this can be used for a wide application area. On Stratasys systems, ABS has made jigs, fixtures, industrial parts and many prototypes. The material is often considered when companies opt to manufacture using 3D printing. For outdoor and longer lifespan ASA is related but in many ways better performing material. If ABS is chosen it usually is because the company has extensively used the material before.

ABS has been in some decline as PETG, PP and PC have brought new functionalities to desktop printers but the material is still one of the most popular.
