PPA-GF is glass-fibre-filled polyphthalamide. Makers sell it for end-use automotive, aerospace and electronics parts. Semicrystalline, it carries light load well above its glass transition, and its HDT at 0.45 MPa is 196 °C. On the H2C every product needs a hardened nozzle, makers advise drying at 80–140 °C, 4–12 h, and some ask for more chamber heat than the H2C gives.
Partly documented Price rests on 1 product, tensile strength (Z) on 2 products, tensile modulus (XY), tensile strength (XY) and HDT at 0.45 MPa on 3 products each and notched Charpy impact is not published. 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
Against PPA-CF, PPA-GF is 14 % less stiff and 7 % weaker flat, and its HDT at 0.45 MPa is 24 °C lower. Against PA6-CF, PPA-GF is 50 % stiffer, 43 % stronger flat and 20 % stronger across the layers. Among the materials, PPA-GF has a high tensile modulus (XY), tensile strength (XY), tensile strength (Z) and HDT at 0.45 MPa, and a low elongation at break (XY): each is in the top or bottom quarter of the materials that publish it. Its density and price sit in the middle half.
PPA-GF is stronger across the layers than PA6-CF, PPS-CF and PAHT-CF but costs less than PPA-CF, PA6-CF and PPS-CF and others

Thermal properties
Its products put HDT at 84–220 °C under 0.45 MPa and 80–118 °C under 1.8 MPa, against a glass transition of 80 °C. Semicrystalline, it carries light load well above its glass transition. As published, Vicat softening is typically 233 °C and melting typically 244 °C.

After printing
Three products publish values measured after annealing, at 100 °C for 8 h.
After the printing, it is recommended to anneal the model in the oven at 80-100°C for 4 to 8 hours and cool the room temperature naturally.

What makers say about printing it
Nozzle wear
Using abrasion resistance nozzle, as hardened steel and above grade nozzle is highly recommended.
Raise3D Industrial PPA GF, data sheet, p. 2
Printing advice
An all-metal hotend capable of reaching and maintaining 320°C is required.
Siraya Tech Fibreheart PPA-GF, data sheet, p. 4
More from makers: warping and shrinkage, supports and removal, moisture sensitivity, adhesion between layers and odour and emissions
Warping and shrinkage
After annealing, max. 0.5% dimensional shrinkage could be observed in Z-axis depending on infill and layer height, no obvious dimensional shrinkage in XY-axis.
Raise3D Industrial PPA GF, data sheet, p. 2
Supports and removal
If PPA GF is used as the support material for itself, please remove the support structure after annealing.
Raise3D Industrial PPA GF, data sheet, p. 2
Moisture sensitivity
After drying, we recommend to store PPA GF filament into Raise3D Filament Dry Box during the printing.
Raise3D Industrial PPA GF, data sheet, p. 2
Adhesion between layers
As a result, Hyper Core PPA GF25 offers not only higher Z-direction strength, smoother surface quality, but also, and above all, higher performance-cost ratio and a wide range of color options.

What makers warn about
However, high-speed printing using fiber-reinforced filament brings many challenges, such as lower flowability and poorer interlayer bonding quality, and quicker wearing out of the nozzle.

On food contact, disposal and safety, as makers state them:
Handle in accordance with good industrial hygiene and safety practice. Do not eat, drink or smoke at the workplace. Avoid dust formation by cutting or grinding. During printing, ensure good ventilation and local exhaust.

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 PPA resin is shown. Fillers, pigments and printing change it, so it does not stand for these products.
