ABS/CF print parameters — temperature, bed, cooling and drying

ABS/CF combines every requirement of ABS with the very high abrasiveness of carbon fibre. A declared temperature resistance of 110 °C, a closed 50 °C chamber, 6–12 h of drying and a hardened nozzle — all at once. It is the most demanding composite in Porima's table.

In return you get a material that is stiff and dimensionally more stable than pure ABS. The manufacturer does, however, rate layer bonding as medium (with ABS it is good) and impact resistance as low — the fibre stiffens the part at the cost of toughness. Plain ABS is covered here: ABS print parameters.

Source: the official Porima FDM technical data table (FDM Technical Data). The descriptive ratings (none / low / medium / high) are the manufacturer's own labels, not the result of testing to any standard. Temperature resistance is the manufacturer's own declared figure — it is not HDT, nor any other normed test. The ±0.03 mm diameter tolerance comes from the manufacturer's data, not from the FDM table. See also the print temperature table and the filament drying guide.

How to print ABS/CF

A hardened nozzle and a 50 °C chamber at the same time

This is the only material in the table that requires both at once: a closed printer with a 50 °C chamber like ABS, and a wear-resistant nozzle like PLA/CF. Abrasiveness: very high. Brass is out.

Temperature 260–280 °C and an 80–110 °C bed

The lower nozzle limit is 10 °C higher than for plain ABS. Warping tendency: high. On large parts a brim is effectively mandatory, and it is better to avoid opening the door mid-print: warping.

Cooling 0–40%

Off by default. With layer bonding rated medium — the lowest in the whole ABS family — every extra percent of fan increases the risk of delamination.

Drying 6–12 h at 40–60 °C

The same as ABS. Moisture resistance: low.

Detail resolution: 0.4 mm and above

As with PLA/CF. The material is not suited to fine detail and thin walls — it is a choice for stiff, structural parts.

Bambu AMS: No

The manufacturer marks ABS/CF as incompatible with the AMS and requires a printer with an enclosure. The odour is rated strong, so ventilating the room is essential. Post-processing: easy with acetone; it dissolves in acetone just like plain ABS.

The most common problems with ABS/CF

• Clogged nozzle — carbon fibre combined with high temperature is the most common cause of a blocked flow
• Warping — a high tendency, as with ABS and PC/ABS — without a 50 °C chamber large parts will not succeed
• Layer delamination — layer bonding is rated medium, the lowest in the ABS family
• Odour and fumes — the odour is classified as strong; print with ventilation
• Dimensional accuracy — the fibre limits shrinkage, but a worn nozzle changes the line width and ruins fits
• Brittle filament — composites crack on a tight bend in the guide more often than unfilled materials
