Nylon-GF, maker-undisclosed polyamide is glass-fibre-filled nylon whose makers do not name the polyamide. A maker sells it for industrial tooling and end-use parts, and its HDT at 0.45 MPa is 152 °C. A maker notes that its mechanical properties may change with absorbed moisture. On the H2C a maker's sheet asks for a hardened nozzle and for drying the filament before it prints.

Among the materials

Against Nylon, maker-undisclosed polyamide, Nylon-GF, maker-undisclosed polyamide is 14 % stiffer and 5 % stronger flat. Against Nylon-CF, maker-undisclosed polyamide, Nylon-GF, maker-undisclosed polyamide is 46 % stronger flat. Among the materials, Nylon-GF, maker-undisclosed polyamide sits in the middle half on every property it publishes comparably.

Nylon-GF, maker-undisclosed polyamide softens 21⁠–⁠92 °C higher than Nylon, maker-undisclosed polyamide, PA12-CF and PC-CF but is less stiff than PA12-CF, PC-CF and PA6-CF

Printing on the H2C

Nylon-GF, maker-undisclosed polyamide prints within the H2C's limits and softens near 152 °C, above its 65 °C chamber

What makers say about printing it

From makers: moisture sensitivity and adhesion between layers

Moisture sensitivity

  • The mechanical properties of Onyx GF may change based on the moisture absorbed from its ambient environment. Markforged Onyx GF, data sheet, p. 2
  • Increased moisture content will result in a more durable part, behavior that is typical of nylon-based materials. Markforged Onyx GF, data sheet, p. 2

Adhesion between layers

  • In tension, most parts are strongest when the print orientation and loading direction are parallel, and weakest when the print orientation and loading direction are perpendicular. Markforged Onyx GF, data sheet, p. 2

Products

Three products from three makers: Eumakers, Filamatrix and Markforged.
