| Identity & Market | ||
| Base polymer / chemistry | ABS reinforced with chopped carbon fibre[1] | Break-away support compounded to survive high-temperature print chambers; 3DXTech sells separate grades for PC/ABS and for the PAEK and PEI class[2][3] |
| Densityg/cm³ | 1.11 (ISO 1183)[1] | 1.37 (3DXTech THERMAX HTS1, ISO 1183)[2] |
| Typical priceUSD/kg | 1 kg-equivalent spools span 22–125; the middle of the market is about 36[4][5][6][7][8] | 1 kg-equivalent spools cluster near 168[4] |
| Price range across brandsUSD/kg | 22–125 across brands; IEMAI 22, Siraya Tech 28 and 36 for the core-shell grade, YXPOLYER 35, Push Plastic 50 at 2 kg, 3DXTech 64 at 750 g; Stratasys-compatible cartridges run far higher[4][5][6][7][9][8] | 100–290 across grades; 3DXTech THERMAX MTS1 100 at 2 kg, HTS2 168 at 250 g, HTS1 250 at 500 g, IEMAI 3D HT-SP 290 at 1 kg[4][10] |

| Typical applications | Stiff tooling and fixtures that must survive above 100 °C[1] | Support for PEEK, PEI and PC-class prints, where PVA and PLA-based supports would decompose[2][3] |
| Printing Parameters | ||
| Enclosure / chamber requirement1–5 | Enclosure recommended[11] | Actively heated chamber required — it is used inside high-temperature builds[2] |
| Bed surface & adhesion aid | Clean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[11][12] | Not documented |
| Warping tendency1–5 | Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ABS[11] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[11] | Not documented |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[13] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[11] | Expert / industrial hardware only[2] |
| Extruder requirement | Not documented | A dual-extruder machine rated for high-temperature materials; 3DXTech states the grade is intended for dual-extruder printers designed to print high-temp materials[14] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[11] | Brass fine indefinitely[2] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[11] | Non-abrasive[2] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened nozzle of 0.4 mm minimum and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[15][16][17] | Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry for HTS1 and 80 °C for MTS1[14][18] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[12] | Not documented |
| Hotend requirement | No special hot-end required[12] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — the ABS matrix takes up 0.51–0.65 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 80 °C, 4 h pre-dry[19][20][15] | Not documented |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[21] | Not documented |
| Effect of moisture on strength | Polymaker 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[21] | No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry for HTS1 and 80 °C for MTS1 because trapped water flashes to steam at these nozzle temperatures[14][18] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity[21] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 46 at break (printed XY, ISO 527)[1] | Not documented |
| Young's modulusMPa | 5210 (printed XY, ISO 527) — more than double unfilled ABS[1] | Not documented |
| Elongation at break% | 2 at break (printed XY, ISO 527)[1] | Not documented |
| Flexural strengthMPa | 76 (printed XY, ISO 178)[1] | Not documented |
| Flexural modulusMPa | 5260 (printed XY, ISO 178)[1] | Not documented |
| Brittleness1–5 | Brittle — snaps with little warning; elongation at break 2 %[1] | Not documented |
| Creep resistance / sustained load1–5 | Good — no creep test found; chopped carbon fibre restrains matrix flow and modulus rises to 5210 MPa against 2200–2330 for unfilled ABS[1][19][20] | Not documented |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve found; elongation at break falls to 2 % against 10.5 % for unfilled ABS[1][19] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Not documented |
| Wear resistance & friction | Not documented | 3DXTech marks tensile strength, modulus and elongation as not applicable for its support grades — they are not characterised as structural materials[2] |
| Thermal Properties | ||
| HDT at 1.8 MPa°C | Not documented | 205 (THERMAX HTS1, printed XY, ISO 75 at 1.8 MPa)[2] |
| Glass transition (Tg)°C | 105 (DSC)[1] | 225 (3DXTech THERMAX HTS1, DSC) — high enough to stay solid inside a PEI or PEEK build[2] |
| Thermal expansion (CTE)µm/m·K | 19–25 along the print bead and 80–84 in the build direction at 30 °C (20 wt% CF, large-format printed, TMA)[22] | Not documented |
| Environment & Chemical | ||
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[23] | Not documented |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[13] | Not documented |
| Biodegradability / compostability | Not biodegradable[13] | Not documented |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[13] | Not documented |
| Electrical & ESD properties | Surface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1] | Surface resistance above 10^13 ohm/sq on all three THERMAX support grades (ASTM D257) — insulating[2][24][3] |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[25][11] | Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[25] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[25] | Not documented |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[25] | Not documented |
| Hazardous species emitted | Styrene 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[25][11] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[25][11] | Open a window / occasional ventilation[25] |
| Dust & fibre handling hazard | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[13] | Not documented |
| Painting & finishing | Paints readily after light abrasion[13] | Not documented |
| Vapour / chemical smoothing | Acetone smoothing is blunted by the fibre — only the resin fraction dissolves[23] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[26][11] | This is the support material. MTS1 is matched to PC/ABS and PC; HTS1 and HTS2 to the higher-temperature classes[3][2] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[27][23] | Aqueous alkali, not water: IEMAI specifies an alkaline bath in an ultrasonic cleaner until the support dissolves.[10] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[27][28] | Not documented |
| Solvent welding & smoothing agent | Acetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[29][23] | None — the alkaline bath dissolves the support rather than welding anything.[10] |
