Identity & Market
Base polymer / chemistryABS reinforced with chopped glass fibre — 3DXTech's grade is nominally 10 wt%[1][2]PLA with a blowing agent. Two distinct types: active-foaming grades that expand at the nozzle (Bambu Lab PLA Aero, colorFabb LW-PLA) and pre-foamed grades that do not (Polymaker PolyLite LW-PLA, PolyWood)[3][4][5][6]
Densityg/cm³1.08 (Bambu Lab) and 1.15 (3DXTech), ISO 1183[2][1]Filament 1.21 (Bambu Lab) and 1.24 (colorFabb); pre-foamed filament 0.8 (PolyWood, at 21.5 °C) and 0.9 (Polymaker LW-PLA); foamed prints reach 0.40[3][4][5][6]
Typical priceUSD/kg1 kg-equivalent spools span 24–73; the middle of the market is about 35[7][8][9][10]1 kg-equivalent spools cluster near 45[11][4][12]
Price range across brandsUSD/kg24–73 across brands; Siraya Tech 24, Bambu Lab 30, SUNLU 40, 3DXTech 73[7][8][9][10]37–50 across brands; Polymaker LW-PLA 37, Bambu Lab Aero 45, colorFabb 50, PolyWood 50[12][11][4]
Market availability1–5Available from several mainstream brands[7][8]Available from several mainstream brands[11][12][4]
Spool sizes & diameters1.75 and 2.85 mm; 750 g and 1 kg spools[8][7]1.75 and 2.85 mm; 0.6, 0.75, 0.8 and 1 kg spools[12][4]
Typical applicationsStiff, dimensionally stable enclosure and tooling parts; Bambu Lab notes the fibre blurs layer lines into a matte finish[2]RC aircraft, drone airframes and large props where mass matters more than strength[3][4]

Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[16]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[13]Intermediate — dry filament and a tuned profile; flow has to be cut to match the expansion[4]

Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors[26]

Food contactNot food safe — Polymaker cites potential chemical leaching[16]Not documented
Biodegradability / compostabilityNot biodegradable[16]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[16]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[28][13]Low hazard — minimal VOC and particle emission[28]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[28]Not documented
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[28]Not documented
Hazardous species emittedStyrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[28][13]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[28][13]None needed in a normal room[28]
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[16]Not documented
Painting & finishingPaints readily after light abrasion[16]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[29][13]Not documented
Dimensional accuracy & detailBambu Lab describes a smooth matte finish with micro-spot gloss that blurs layer lines[2]Foamed surfaces are rough and matte; dimensional accuracy depends on holding the foaming temperature steady[3][4]
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[30][27]Chloroform dissolves the PLA matrix; the foamed wall wicks solvent right through instead of only skinning over.[31]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[30][32]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[31][33]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[33][27]Chloroform vapour reaches only the resin skin; no workshop-safe smoothing agent exists for PLA of any kind.[34][33]
