| Property | Glass-fibre PA12 (PA12-GF)PA | Matte PLAPLA |
|---|---|---|
| Market snapshot | ||
| Listing priceUSD/kg; dated snapshots | $130.67/kg median; $46.00–$140.18/kg across 3 dated product listings | $19.09/kg median; $10.99–$32.16/kg across 10 dated product listings |
| Identity & Market | ||
| Base polymer / chemistry | PA12 reinforced with chopped glass fibre — 3DXTech's grade is nominally 30 wt%[1] | PLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[2][3] |
| Densityg/cm³ | 1.23 (ISO 1183)[1] | 1.31 (Bambu Lab, ISO 1183) to 1.38 (Fiberlogy PLA Mineral, method not stated) — above plain PLA from the filler[3][2] |
| Typical priceUSD/kg | 1 kg-equivalent spools span 46–140; the middle of the market is about 88[4][5][6] | Mainstream 1 kg spools cluster near 21[7][8][9] |
| Price range across brandsUSD/kg | 46–140 across brands; IEMAI 3D 46, 3DXTech 131 at 750 g and 130 at 2 kg, PrimaCreator NylonPower Glass Fiber 140 at 500 g[4][5][6] | 11–32 across brands; budget house brands 11–19, Fiberlogy PLA Mineral 32[10][8][11] |
| Market availability1–5 | Available from several mainstream brands[4][5] | Stocked by most mainstream brands[10][9][7] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.5, 0.75 and 2 kg spools[4][6] | 1.75 mm; 1 kg spools plus spool-less refills[7][12] |
| Typical applications | Stiff, humidity-stable structural parts — the glass gives the modulus, the PA12 matrix limits the moisture drift[1][13] | Display models and visible parts where a matte, non-reflective finish matters[3] |
| Diameter tolerance± mm | Not documented | ±0.03 (Bambu Lab)[14] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[3][2] |
| Bed temperature°C | Not documented | 35–45 (Bambu Lab); 60 (Fiberlogy)[3][2] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive)[15] | Open frame is fine[3][2] |
| Part cooling fan | Not documented | Fan on; Fiberlogy specifies 75–100 %[3][2] |
| Bed surface & adhesion aid | PEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[16][15] | Cool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[3][2] |
| Warping tendency1–5 | Not documented | None[3] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[16] | Sticks to anything[17] |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed[15] | Not documented |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning[15] | Beginner — prints on any machine out of the box[3][2] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required — no nozzle-life figure is published for a PA12-GF30 grade; Polymaker measures about 9 h of brass nozzle life on its comparable fibre-filled nylons[18] | Brass fine indefinitely[19][3][2] |
| Abrasiveness1–5 | Highly abrasive — standard GF composite[18] | Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[2][3][20] |
| Nozzle clog risk1–5 | High — jams from moisture, heat creep or particles[21] | Very low[19] |
| Heat-creep / jam sensitivity1–5 | Moderate — good heatbreak cooling needed[16] | Moderate — good heatbreak cooling needed; PLA softens below 60 °C[22] |
| Hotend requirement | May require an all-metal hot end (Simplify3D)[16] | No special hot-end required[17] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | High (0.8–2 %) — the PA12 matrix takes up far less than PA6, on the evidence of Polymaker's 1.5 % for PA12-CF10 against 3.33 % for PA6-GF25[23][24] | Moderate — 0.40 % saturated at 25 °C / 55 % RH[3] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[3] |
| Drying temperature & time | Not documented | 50 °C for 8 h in a forced-air dryer, or 60–70 °C for 12 h on an X1 heatbed; Fiberlogy specifies 50 °C for 6 h[3][2][25] |
| Symptoms when wet | Not documented | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[21] |
| Effect of moisture on strength | Polymaker's PA12 grades change little between wet and dry, unlike PA6; the CoPA dry-to-wet blocks show the PA6-type response[13][26] | Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[21] |
| Storage requirement | Sealed below 20 % RH with desiccant[21] | Sealed with desiccant below 20 % RH; shelf life at ambient is long[20][17] |
| Hydrolysis at melt temperature | Polymaker specifies an 80–100 °C dry and storage below 20 % RH; no molecular-weight loss figure is published, and the wet data it does publish is conditioning rather than melt hydrolysis[18][26] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 82 at break (printed XY, ISO 527)[1] | 30 (printed XY, ISO 527, Bambu Lab); 35.1 on My Tech Fun bars for PolyTerra PLA[3][27] |
| Young's modulusMPa | 7800 (printed XY, ISO 527)[1] | 1960 (Bambu Lab, printed XY, ISO 527); Fiberlogy PLA Mineral quotes 3500 (ISO 527, specimen type not stated)[3][2] |
| Elongation at break% | 4.5 at break (printed XY, ISO 527) — nearly double the 2.4 % of Polymaker's PA6-GF25[1][24] | 14.8 (printed XY, ISO 527)[3] |
| Flexural strengthMPa | 94 (printed XY, ISO 178)[1] | 53 (printed XY, ISO 178) — 30 % below PLA Basic at 76[3][20] |
| Flexural modulusMPa | 7550 (printed XY, ISO 178)[1] | 2360 (printed XY, ISO 178)[3] |
| Charpy impact, notchedkJ/m² | Not documented | 6.3 (printed XY, ISO 179, notched); unnotched 19.2[3] |
| Other impact data | Not documented | Izod 6.1 kJ/m² on My Tech Fun printed bars for PolyTerra PLA[27] |
| Layer adhesion / Z tensileMPa | Not documented | 22 (printed Z, ISO 527); flexural Z falls to 29 against 53 in XY; 12.9 on My Tech Fun layer-adhesion bars[3][27] |
| Brittleness1–5 | Moderate[1] | Brittle — snaps with little warning[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Rockwell M88 / R117 on extruded PA66-GF30 stock (ASTM D785); no figure is published for a glass-fibre PA12 filament[28] | Not documented |
| Creep resistance / sustained load1–5 | Good. Ensinger lists high creep resistance for extruded PA66-GF30 stock, and the PA12 matrix absorbs far less water than PA6, so a PA12-GF part holds load better in a humid environment[28][15] | Poor — 12 mm bar sagged to 18.7 mm over 5 days at 1.25 kg[27] |
| Fatigue / repeated-flex resistance1–5 | Good. Ensinger lists high fatigue strength as a headline property of extruded PA66-GF30 stock[28] | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[29][22] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[3] |
| Z strength as % of XY% | Not documented | 73 by tensile, 55 by flexural (printed, Bambu Lab)[3] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 58 (Bambu Lab) and 48 (Fiberlogy PLA Mineral), ISO 75 at 0.45 MPa[3][2] |
| HDT at 1.8 MPa°C | Not documented | 52 (ISO 75, 1.8 MPa)[3] |
| Glass transition (Tg)°C | Not documented | 61 (DSC)[3] |
| Melting point / Vicat°C | Not documented | 163 peak melt (DSC); Vicat 63 °C[3] |
| Continuous service temperature°C | Not documented | 54 — loaded bars begin to move at this temperature[27] |
| Annealing response | Not documented | 50–60 °C for 6–12 h; some prints deform or warp, and a forced-air oven is required[3] |
| Thermal expansion (CTE)µm/m·K | 48.6 on extruded PA66-GF30 stock (ASTM D696; source states 2.7e-5 in/in/°F) — no figure is published for a glass-fibre PA12 filament[28] | Not documented |
| Flammability / UL 94 | Flammable; no UL 94 rating published for the grades surveyed[18] | Flammable; no UL 94 rating published by the major brands[20][30] |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement — unstabilised polyamide yellows under UV[15] | Degrades within weeks outdoors[22][31] |
| Chemical resistance | Withstands oils, fuels and alkalis[15] | Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[30][22] |
| Water / humidity resistance in service1–5 | Good — minor absorption relative to PA6-based composites[13] | Good — insoluble in water[20] |
| Food contact | Not food-contact certified as filament[15] | Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[22] |
| Biodegradability / compostability | Not biodegradable[15] | Industrially compostable only — needs sustained 55 °C; not home compostable[32][22] |
| Recyclability | Not accepted in household plastic collection[15] | Mechanically recyclable; not accepted in household plastic collection[32] |
| Electrical & ESD properties | Surface resistance above 10¹³ ohm/sq — insulating (ASTM D257)[1] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[33] | Low hazard — minimal VOC and particle emission[33] |
| VOC emission rateµg/min | Up to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[33] | Not documented |
| Ultrafine-particle emission rateparticles/min | ≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[33] | Not documented |
| Hazardous species emitted | Caprolactam, at up to 180 µg/min from nylon filament[33] | Not documented |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[33] | None needed in a normal room[33] |
| Dust & fibre handling hazard | Glass fibre is bound in the matrix; avoid inhaling sanding dust[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands poorly — gums rather than powders[16] | Wet sanding — dry sanding heats the surface by friction and smears it[31][22] |
| Gluing & solvent welding | Cyanoacrylate; no common solvent welds polyamide[16] | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[22][34] |
| Vapour / chemical smoothing | No practical vapour smoothing[16] | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[22] |
| Support material pairing | Not documented | Support for PLA (Bambu Lab)[3] |
| Dimensional accuracy & detail | Not documented | Matte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[3] |
| Solvents & Solubility | ||
| Soluble in | Formic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[35] | Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[36] |
| Softened or crazed by | Zinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[35] | Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[36][37] |
| Solvent welding & smoothing agent | None — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[35] | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[38][37] |
