PC-GF is glass-fibre-filled polycarbonate. Makers sell it for technical applications that need stiffness and heat resistance. Its glass transition is 142 °C, and makers warn that polycarbonate is highly hygroscopic, prone to stress cracking and notch sensitive. On the H2C it prints at 290–320 °C, and makers recommend a hardened steel nozzle against the abrasive glass and drying before printing.
Thinly documented Three products, with values from three makers' documents: SIDDAMENT's, BASF Forward AM's and Fabru's. Read each figure as a few sheets' word.

Among the materials
Against PC, PC-GF is 55 % weaker across the layers and 37 % weaker flat. Against PC-ABS, PC-GF is 22 % weaker across the layers and 9 % weaker flat. Among the materials, PC-GF has a low tensile strength (Z) and price: both are in the lowest quarter of the materials that publish them. The rest of its key properties sit in the middle half.
Against its alternatives, PC-GF has the lowest tensile strength and tensile strength (Z)
How does it compare with what an engineer would buy instead?
- PC-GF: its products' median and middle half
- an alternative
- lowest to highest
- each material's median (top row)
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.

Printing on the H2C
PC-GF softens near 134 °C, above the H2C's 65 °C chamber; 1 product asks for more than the H2C gives
What does printing it on the H2C take, and how hot can a part get?

Nozzle wear
Printing with Ultrafuse® PC GF30 may reduce brass nozzles and extruder driving wheels’ lifetime.

Uses, limitations and chemicals
What it is sold for
Combines PC's high-temperature performance with the rigidity and dimensional stability of glass fibre.
SIDDAMENT V2 PC-GF, data sheet, p. 1The extreme stiffness makes this material highly suitable for demanding applications.
BASF Forward AM Ultrafuse PC GF30, data sheet, p. 1In addition to the high print quality, the high mechanical strength and the heat resistance, the glass fiber reinforced PC offers excellent impact strength and fracture toughness and is therefore the ideal choice for technical applications.

Where no maker of these products speaks to an exposure, reference data for plain PC resin is shown. Fillers, pigments and printing change it, so it does not stand for these products.
