Identity & Market
Base polymer / chemistryPolyether block amide: rigid polyamide and flexible polyether blocks.[1]PLA filled with chopped glass fibre — 12 wt% (Polymaker HT-PLA-GF), 15–20 wt% (eSUN PLA-GF). Bambu Lab PLA Galaxy uses glass microspheres, not fibre, and is not equivalent[2][3][4]
Densityg/cm³1.01 g/cm³ (GB/T 1033; eSUN manufacturer data)[1]1.31 (eSUN) to 1.337 (Polymaker), ISO 1183 / GB/T 1033[2][3]
Typical priceUSD/kgNot documented1 kg spools cluster near 30[5][6]
Price range across brandsUSD/kgNot documented30–60 across brands; Polymaker 30, Proto-pasta 60[5][6]
Market availability1–5Not documentedNiche, a handful of specialist brands[5][6][3]
Spool sizes & diameters1.75 mm diameter, 1 kg spool.[7]1.75 mm; 0.5 and 1 kg spools[6][8]
Typical applicationsManufacturer applications include footwear, sports equipment and cushioning.[1]Stiff brackets and fixtures; the Polymaker grade is aimed at parts annealed for heat resistance[2]
Printing Parameters
Nozzle temperature°C230–260 °C; 240 °C recommended.[1]210–230 (Polymaker HT-PLA-GF)[2]
Bed temperature°C60–90 °C[1]25–60 (Polymaker HT-PLA-GF)[2]
Enclosure / chamber requirement1–5Not documentedOpen frame is fine[2]
Part cooling fan10–50% fan recommended; mechanical-test specimens used 50–100%.[1]Fan on — eSUN specifies 100 %[3]
Bed surface & adhesion aidPEI build plate[1]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s9 mm³/s maximum in eSUN spiral-vase test; mechanical specimens used 2 mm³/s. Linear recommendation 25–110 mm/s is a separate quantity.[1]28 at Polymaker's stated 350 mm/s on a 0.4 mm nozzle at 0.2 mm layer; eSUN prints its specimens at 60 mm/s[2][3][9]
Shrinkage%Not documented0.05 in X-Y and Z, 0.10 diagonal (Polymaker HT-PLA-GF)[2]
Overall printing difficulty1–5Not documentedIntermediate — dry filament and a tuned profile; hardened nozzle mandatory[2]
Hardware Wear & Reliability
Nozzle hardness required1–4Not documentedHardened steel required[2]
Abrasiveness1–5Not documentedHighly abrasive — standard GF composite[2]
Nozzle clog risk1–5Not documentedModerate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[10]
Hotend requirementNot documentedHardened steel or ruby nozzle; Polymaker's own slicer preset sets a minimum nozzle hardness of 40 HRC[2]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Not documentedModerate — the PLA matrix takes up 0.40–0.51 % saturated; no glass-filled grade publishes its own figure[11][12]
Drying temperature & time70–75 °C for 6–8 h; re-dry after receiving or extended exposure.[1]60 °C for 6 h (Polymaker HT-PLA-GF)[2]
Effect of moisture on strengthNot documentedPolymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for this grade; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[13]
Mechanical Properties
Tensile strength (XY)MPa>16.5 MPa printed XY, GB/T 1040; manufacturer lower bound, not an exact measurement.[1]50.1 as printed and 50.2 annealed, printed XY, ISO 527 (Polymaker); eSUN quotes 59.3 by GB/T 1040[2][3]
Young's modulusMPaNot documented3794 as printed, 4207 annealed, printed XY, ISO 527 (Polymaker)[2]
Elongation at break%>520% printed XY, GB/T 1040; manufacturer lower bound.[1]2.77 as printed, 2.3 annealed, printed XY, ISO 527 (Polymaker); eSUN quotes 7.99[2][3]
Flexural strengthMPaNot documented86.4 printed XY, ISO 178 (Polymaker)[2]
Flexural modulusMPaNot documented3685 printed XY, ISO 178 (Polymaker); eSUN quotes 4415 flexural modulus by GB/T 9341[2][3]
Charpy impact, notchedkJ/m²Not documented5.31 ± 0.46 as printed and 4.92 ± 0.50 annealed (printed XY, ISO 179, notched); Z 4.28 ± 0.18[2]
Other impact dataNot documentedIzod 10.16 kJ/m² (eSUN, GB/T 1843)[3]
Layer adhesion / Z tensileMPa7.5 MPa printed Z, GB/T 1040 (manufacturer test)[1]23.7 as printed, 22.5 annealed, printed Z, ISO 527 (Polymaker)[2]
Brittleness1–5Not documentedVery brittle — elongation at break 2.77 % in XY and 0.85 % in Z[2]
Hardness (scale-specific)Shore A / Shore D / Rockwell90 Shore A nominal grade designation; do not compare numerically with Shore D or Rockwell.[7]Not documented
Creep resistance / sustained load1–5Not documentedPoor — no GF-grade creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[14][15][16]
Fatigue / repeated-flex resistance1–5Not documentedPoor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and elongation at break falls to 2.77 % in XY and 0.85 % in Z[17][2]
Elasticity / flexibility1–5Not documentedRigid[2]
Z strength as % of XY%Not documented47 as printed (23.7 Z against 50.1 XY), printed[2]

Thermal Properties
HDT at 0.45 MPa°CNot documented75.5 as printed, 114.7 after annealing (ISO 75, 0.45 MPa) — the point of the material[2]
HDT at 1.8 MPa°CNot documented59.7 as printed, 84 after annealing (ISO 75, 1.8 MPa)[2]
Glass transition (Tg)°CNot documented59.8 (DSC)[2]
Melting point / Vicat°C110 °C Vicat softening (GB/T 1633, 120 °C/h, 10 N); not HDT or a continuous-use rating.[1]174.9 peak melt (DSC); Vicat 148.9 as printed, 148.3 annealed[2]
Annealing responseNot documentedAnnealing lifts HDT at 0.45 MPa from 75.5 to 114.7 °C and modulus from 3794 to 4207 MPa[2]
Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors[18]
Health & Safety
Fume toxicity1–5Not documentedLow hazard — minimal VOC and particle emission[19]
Ventilation / filtration requirement1–5Not documentedNone needed in a normal room[19]
Dust & fibre handling hazardNot documentedGlass fibre is bound in the matrix; avoid inhaling sanding dust[20]
Post-Processing
Dimensional accuracy & detailNot documentedNear-zero shrinkage — 0.05 % in X-Y and Z (Polymaker)[2]
Solvents & Solubility
Soluble inNot documentedChloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[21]
Softened or crazed byNot documentedAcetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[21][22]
Solvent welding & smoothing agentNot documentedChloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[23][22]

Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
