Printing Parameters
Nozzle temperature°C240–270 (Spectrum); 240–280 (ZYLtech)[1][2]190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][4]
Bed temperature°C80–100 (Spectrum); 90–110 on PEI (ZYLtech)[1][2]35–45 (Bambu Lab); 50–70 (Fiberlogy)[5][6]
Enclosure / chamber requirement1–5Enclosure recommended[16]Open frame is fine[5]
Part cooling fan0–20 % (Spectrum)[1]Fan on[5]
Bed surface & adhesion aidPEI sheet, BuildTak or an adhesion aid such as Magigoo (Polymaker); Simplify3D also lists Kapton tape and ASA slurry[17][18]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s2.4–5.6 at Spectrum's 30–70 mm/s on a 0.4 mm nozzle at 0.2 mm layer; ZYLtech allows up to 200 mm/s[1][2][19]Not documented
Warping tendency1–5Moderate — needs adhesion aid or draught shield[16]None[5]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[17]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[17]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; ZYLtech requires a hardened nozzle of 0.6 mm or larger[2][1]Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[20][5]
Extruder requirementZYLtech specifies a hardened nozzle 0.6 mm or larger; Spectrum bases its settings on a 0.5 mm nozzle[2][1]Nozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[20]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — Spectrum recommends ruby or hardened, ZYLtech requires hardened[1][2]Brass acceptable; hardened steel for volume work — Bambu Lab's PLA compatibility table lists no hardened-nozzle requirement, but its nozzle guide names wood among the abrasive filaments hardened steel exists for[20][21]
Abrasiveness1–5Highly abrasive — standard GF composite[1][2]Moderately abrasive — wood fill[20]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[22]Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[20]
Heat-creep / jam sensitivity1–5Slightly sensitive[18]Not documented
Hotend requirementNo special hotend required[18]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — the ASA matrix takes up 0.40–0.45 % saturated at 25 °C / 55 % RH; no glass-filled grade publishes its own figure[23][24][25]High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5]
Equilibrium moisture content at ~50 % RH%Not documented1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[5]
Drying temperature & timeNot documented55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][20]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[26]Bambu Lab flags pre-drying and ventilation as specific requirements for this grade[20]
Effect of moisture on strengthNo dry-versus-conditioned figures are published; Polymaker groups the styrenics as moderate-sensitivity and absorbed water shows as bubbling and poor layer adhesion[26]No dry-versus-conditioned figures are published. At 1.25 % saturated uptake the practical loss shows as poor layer adhesion, rough surface and weak layers[26][5]
Storage requirementSealed with desiccant; Polymaker rates the styrenics moderate-sensitivity[26]Not documented
Mechanical Properties
Tensile strength (XY)MPa33–36 at break, ISO 527 (ZYLtech; specimen type not stated); Spectrum quotes 55 at break on injection-moulded specimens[2][1]26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[5][4][6]
Young's modulusMPa2540–2890 (ZYLtech; specimen type not stated) and 2550 (Spectrum, injection-moulded), ISO 527[2][1]2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[5][4][6]
Elongation at break%3.4 at break (ZYLtech; specimen type not stated); Spectrum quotes 2.80 at yield on injection-moulded specimens[2][1]4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[5][4][6]
Flexural strengthMPaNot documented55 ± 4 printed XY, ISO 178 (Bambu Lab)[5]
Flexural modulusMPa2130–2480 flexural modulus, ISO 178 (ZYLtech; specimen type not stated)[2]2780 ± 120 printed XY, ISO 178 (Bambu Lab)[5]
Charpy impact, notchedkJ/m²8.3 notched Charpy at 23 °C on injection-moulded specimens (Spectrum, ISO 179-1eA); ZYLtech publishes notched Izod 6.9 by ISO 180 instead[1][2]3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[5][4]
Other impact dataCharpy unnotched 25 kJ/m² at 23 °C on injection-moulded specimens (Spectrum, ISO 179-1eU); ZYLtech notched Izod 6.9 kJ/m² (ISO 180)[1][2]Charpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[5][4]
Layer adhesion / Z tensileMPaNot documented15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[5]
Brittleness1–5Brittle — snaps with little warning; elongation at break 3.4 %[2]Brittle — snaps with little warning[5]
Creep resistance / sustained load1–5Good — no creep test found; chopped glass fibre lifts modulus to 2540–2890 against 2379–2450 for unfilled ASA[2][24][23]Poor — no wood-filled creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[27][28][29]
Fatigue / repeated-flex resistance1–5Below average — no GF-grade S-N curve; elongation at break falls to 3.4 % against 6.7–9.2 % for unfilled ASA[2][24][23]Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and the wood filler cuts elongation and the parts snap without warning[30][5]
Elasticity / flexibility1–5Rigid[2]Rigid[5]
Z strength as % of XY%Not documented58 by tensile, 51 by flexural (printed, Bambu Lab)[5]
Thermal Properties
HDT at 0.45 MPa°C100 (Spectrum, injection-moulded, ISO 75 at 0.45 MPa)[1]60 (ISO 75, 0.45 MPa)[5]

Continuous service temperature°C93 — Prusa publishes this as the temperature resistance of Prusament ASA[31]Not documented
Flammability / UL 94Flammable; no UL 94 rating published[23]Not documented
Environment & Chemical
UV resistance1–5Excellent — designed for permanent outdoor use; Spectrum states the parts resist prolonged UV and moisture exposure[1][32]Degrades within weeks outdoors[33]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[24]Not documented
Food contactNot food safe[17]Not documented
Biodegradability / compostabilityNot biodegradable[17]Not documented
RecyclabilityNot accepted in household plastic collection[17]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[34][16]Low hazard — minimal VOC and particle emission[34]
Hazardous species emittedStyrene. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea. Azimi et al. measured styrene from every styrenic filament tested but did not test ASA itself[16][34]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration[34][16]None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[20]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[17]Sands and stains like timber — the usual reason for choosing it[4]
Painting & finishingPaints readily; ASA holds colour outdoors so many parts are left unpainted[17]Not documented
Gluing & solvent weldingSolvent-welds with acetone[24]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works[24]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a Support for ABS that also serves ASA[16]Support for PLA (Bambu Lab)[5]
Dimensional accuracy & detailNot documentedWood grain hides layer lines; colour darkens with nozzle temperature[5][4]
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre; MEK, THF, ethyl acetate and chlorinated solvents attack the styrenic backbone.[35][24]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[36]
Softened or crazed byLimonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[37]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[36][38]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[38][24]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[39][38]
