Identity & Market
Base polymer / chemistryABS reinforced with chopped glass fibre — 3DXTech's grade is nominally 10 wt%[1][2]A carbon-filled compound conductive by volume rather than merely dissipative; Proto-pasta's is PLA-based, Recreus's and NinjaTek's are TPU, and add:north's Koltron G1 does not state its base polymer[3][4][5][6]
Densityg/cm³1.08 (Bambu Lab) and 1.15 (3DXTech), ISO 1183[2][1]Not documented
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 span 90–181 for the carbon-filled grades; add:north's Koltron G1 sits far above at 796 because it is sold only in 100 and 250 g coils[11][12][13]
Price range across brandsUSD/kg24–73 across brands; Siraya Tech 24, Bambu Lab 30, SUNLU 40, 3DXTech 73[7][8][9][10]90–796 across brands; Proto-pasta conductive PLA 90 at 1 kg, Recreus Conductive Filaflex 160 at 500 g, NinjaTek Eel 181 at 1 kg, add:north Koltron G1 796 at 250 g[11][4][12][13]
Market availability1–5Available from several mainstream brands[7][8]Niche, a handful of specialist brands[11][4]

Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[20]Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[20]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[20]Not documented

Biodegradability / compostabilityNot biodegradable[17]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[17]Not documented
Electrical & ESD propertiesNot documentedConductive rather than dissipative — Proto-pasta sells the grade as electrically conductive composite PLA[3]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[23][14]Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[23]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[23]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[23]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[23][14]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[23][14]Open a window / occasional ventilation[23]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[3]
Post-Processing
Sanding & machiningSands well and takes filler before painting[17]Not documented
Painting & finishingPaints readily after light abrasion[17]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[24][14]Not documented
Dimensional accuracy & detailBambu Lab describes a smooth matte finish with micro-spot gloss that blurs layer lines[2]Not documented
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[25][22]Chloroform dissolves PLA-based grades, leaving the carbon black; TPU-based grades need DMF, NMP or THF. Laboratory reagents.[26][27]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[25][28]Acetone and ethyl acetate plasticise a PLA-based grade; a TPU-based grade swells in toluene, esters and alcohols.[26][27]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[29][22]None — neither PLA nor TPU has a workshop-safe welding or smoothing solvent.[26][27]

Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ.
