ASA-CF is carbon-fibre-filled acrylonitrile styrene acrylate. Makers sell it for durable large models and outdoor parts, citing UV stability. Its HDT at 0.45 MPa is 101 °C, and across the layers it keeps 56 % of its flat stiffness. On the H2C it needs a hardened nozzle, and makers advise drying it before printing.

Partly documented Notched Charpy impact rests on 3 products and tensile strength (Z) on 4 products. Each figure is the median of the products that publish it comparably, and beside it the middle half of them; a value on a test bar no document describes as printed, or with no stated test load, is set apart, except a heat deflection of a plastic that cannot crystallise, which its glass transition sets, unless its document points to a moulded or resin bar.

Among the materials

Carbon fibre raises ASA's HDT at 0.45 MPa by 6 °C: ASA-CF's HDT at 0.45 MPa is 101 °C against 96 °C. Against ASA-GF, ASA-CF is 69 % stiffer and 12 % stronger across the layers, and its HDT at 0.45 MPa is 8 °C higher. Among the materials, ASA-CF has a high tensile modulus (XY) and a low density: both are in the top or bottom quarter of the materials that publish them. The rest of its key properties sit in the middle half.

Against its alternatives, ASA-CF has the lowest notched Charpy impact

Mechanical properties

Printed flat (XY), ASA-CF typically reaches a tensile strength of 39.1 MPa at a modulus of 3.91 GPa, and breaks at 6.3 % elongation. In bending, its flexural strength is typically 78 MPa at a flexural modulus of 3.74 GPa.

ASA-CF's products spread most in elongation at break: the middle half runs 2.1⁠–⁠14 %

Where it counts fewer products than the Z median, the others publish no flat value of the same test from the same sheet; the figure's table names them. How XY and Z differ.

Thermal properties

ASA-CF's HDT is typically 101 °C under 0.45 MPa and 96 °C under 1.8 MPa, against a glass transition of 105⁠–⁠107 °C. As published, Vicat softening is typically 102 °C.

What makers say about printing it

Nozzle wear

Printing advice

  • Additionally, a nozzle diameter of at least 0.6 mm should be used to prevent clogging and ensure smooth extrusion. Extrudr DURAPRO ASA CF, data sheet, p. 1
More from makers: moisture sensitivity, supports and removal, warping and shrinkage, adhesion between layers and odour and emissions

Moisture sensitivity

  • As the ASACF10 filament absorbs moisture easily due to the added carbon fiber, it should be dried before being used. Flashforge ASACF10, data sheet, p. 3

Supports and removal

  • High heatbed temperatures and glue stick can cause strong adhesion between the print and the build plate. Please allow the print to cool down to room temperature naturally for easier removal and to avoid damage to the model. For more details, please refer to: Work After Printing Finished on WIKI. Bambu Lab ASA-CF, maker's product page or guide, p. 1

Warping and shrinkage

  • At the same time, it also reduces the impact of curled edges during the printing process, greatly improving the dimensional accuracy and stability of the model. Eryone ASA-CF, data sheet, p. 1

Adhesion between layers

  • DuraPro ASA CF is optimised for good layer adhesion, thermal stability, better flow properties and lower warping. Extrudr DURAPRO ASA CF, data sheet, p. 1

Uses, limitations and chemicals

What it is sold for

What makers warn about

Finish and accuracy
  • when the printing speed is too high, the melt flow state will become unstable, and the filaments extruded from the nozzle will no longer have the skin-core structure anymore, which can cause the rough surface of the printed part. QIDI ASA-CF20 Core, data sheet, p. 5
  • All of this, combined with a carbon matt surface that effectively masks the layers. Spectrum ASA-X CF10, data sheet, p. 1
  • A state-of-the-art manufacturing process achieves very low manufacturing tolerances, which leads to impressive printing results for all FDM 3D printers. Fabru ASA CF10, maker's product page or guide, p. 1
