ASA-GF is a glass-fibre-filled acrylonitrile styrene acrylate. Makers sell it for end-use parts such as garden furniture and automotive interiors, and they report excellent resistance to outdoor exposure. Its HDT at 0.45 MPa is 88–98 °C, below its glass transition, and across the layers it keeps 67 % of its flat tensile strength. On the H2C most products need a hardened nozzle.
Partly documented Price rests on 1 product, tensile modulus (XY), tensile strength (Z) and HDT at 0.45 MPa on 2 products each, tensile strength (XY) on 3 products and notched Charpy impact is published only on test bars no document describes as printed. 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
Glass fibre adds little to ASA's heat resistance: ASA-GF's HDT at 0.45 MPa is 93 °C against 96 °C. Against ASA-CF, ASA-GF is 41 % less stiff and 11 % weaker across the layers, and its HDT at 0.45 MPa is 8 °C lower. Among the materials, ASA-GF has a low density: it is in the lowest quarter of the materials that publish it. The rest of its key properties sit in the middle half.
ASA-GF costs more than ASA, ASA-CF and ABS-CF and others but is less stiff than ASA-CF, ABS-CF and ABS-GF and others
How does it compare with what an engineer would buy instead?
- ASA-GF: its products' median and middle half
- an alternative
- lowest to highest
- each material's median (top row)
- set apart: test bar not described as printed, or no stated load
Each row is a material, each column a property: the bar is the middle half of a material's products, the tick their median, the hairline their lowest to highest; the ticks above the rows are every material's median.

The middle half of the products under each median. The share is each product's Z value as a part of its XY value, from one sheet and one state, and the median of those shares. 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
Its products put HDT at 88–98 °C under 0.45 MPa, against a glass transition of 103–104 °C. As published, Vicat softening is typically 101 °C.

Printing on the H2C
ASA-GF prints within the H2C's limits and softens near 93 °C, above its 65 °C chamber
What does printing it on the H2C take, and how hot can a part get?

- what most products accept

More from makers: printing advice, moisture sensitivity, adhesion between layers and supports and removal
Printing advice
After the printing process, it is recommended to dry the model in the oven at 80°C for 1-3 hours to increase the strength of the model.
Flashforge ASAGF10, data sheet, p. 3
Moisture sensitivity
As the ASAGF10 filament absorbs moisture easily due to the added glass fiber, it should be dried before being used.
Flashforge ASAGF10, data sheet, p. 3
Adhesion between layers
DuraPro ASA GF is optimized for good adhesion layer, thermal stability, improved flow properties, and low warping.

Chemicals and environment

| UV and outdoor | Described in words, with no rating, in all 5 statements |
Makers rarely give the concentration, temperature or duration: treat them as indications, not design data. Each product's statements are on its card.
Where no maker of these products speaks to an exposure, reference data for plain ASA resin is shown. Fillers, pigments and printing change it, so it does not stand for these products.
