ABS Filament

A durable, machinable engineering material

Among 3D printing filaments, ABS is suited to applications beyond the range of PLA and PETG: parts exposed to heat, parts that are drilled and tapped, and parts subject to repeated mechanical stress. It prints on any enclosed 3D printer. It is the material used in many power tool housings, and it accepts sanding, acetone welding and finishing to a gloss surface.

Print settings and warping

Print at 235–250 °C with a 90–110 °C bed.

ABS contracts as it cools, and contraction combined with air movement can cause corners to lift from the plate. An enclosure, a draught-free environment and minimal part cooling are necessary for reliable results. Without an enclosure, ABS is difficult to print reliably on parts larger than a small footprint. This is inherent to the material rather than a fault of any particular brand.

Heat resistance

ABS remains rigid to approximately 95 °C, compared with roughly 60 °C for PLA. This margin is the primary reason to accept the additional handling requirements: parts near heat sources or in high-temperature environments perform where PLA would not.

Ventilation

ABS emits styrene and ultrafine particles during printing, accompanied by a noticeable odour. It is not acutely hazardous, but prolonged printing in an unventilated room is not advisable. Use an enclosure, vent or filter the exhaust, and ventilate the space. Where this is not possible, PETG or ASA is a practical alternative with minimal compromise.

Drying

ABS absorbs less moisture than Nylon but enough to cause bubbling and weak layers when stored open. Dry at 65–70 °C for 4 to 6 hours.

Colours and spools

16 colours: Black, White, Gray, Silver, Natural, Red, Maroon, Orange, Yellow, Green, Lime Green, Blue, Light Blue, Purple, Pink and Brown. Spools of 250 g / 100 m, 750 g / 300 m and 1 kg / 400 m.
