Fillamentum Extrafill ABS traffic red

Fillamentum ABS Extrafill is a material for the FFF (also known as FDM) 3D printing technology.

The advantage of this material is that it can be used in 3D printers easily, that it allows a high quality of printing even in tricky details and an excellent lamination of the printed object.

ABS filament is a polymer which is ideal for the production of the first functional samples before serial production for functional prototyping, manufacturing tools, but also for the production of goods for everyday use.

This material can be used for production of electrical and electronic equipment. It doesn’t contain the restricted substances. The use of the material in the food or medical industry is not recommended.

Fillamentum guarantees high precision of filament dimensions within the tolerance of +/- 0,05 mm, which is strictly controlled throughout the production.

Print settings suggested by manufacturer

• Printing temperature: 220 - 240 °C
• Heated bed temperature:  80-105 °C
• Speed: 30 - 50 mm/s 
• Part cooling fan: 0 - 20 % (5% is a good start)
• Heated bed surface: PEI, mirror/glass
• Adhesive: Dimafix, PVA glue, 3DLac, Magigoo
• Raft / skirt / brim: Brim 5-10 mm
• Heated chamber / enclosure: recommended

Cooling

It is not recommended to use more than 20 % of fan speed, as too much cooling could lead to improper layer bonding and warping. We recommend using no cooling for standard objects, which leads to stronger parts. For bridges and big overhangs, it is possible to go up to 30–40 % for the desired layer.

Adhesion

Brim 5 – 10 mm. The best adhesion was achieved with Dimafix on clean glass or mirror. On the PEI we recommend using wider brim for large objects.

Overhangs

For the overhangs higher than 45° we recommend using lower layer heights and also enough time to cool, otherwise, overhangs could slightly warp.

Printing speed

ABS is better to print little bit slower. Material has more time to bond properly preventing the layer separation and cracks between layers

Note Hotend:

The manufacturer gives very conservative values. Cooling recommended for chamber printing 30-40% depending on cooling capacity (except for first layers), for bridges and overhangs cooling can be increased up to 60%. The speed is realistically limited more by the flow rate of the hotend used. When printing and specially on glass with Dimafix, brim is not necessary even for large prints.
