| Identity & Market | ||
| Base polymer / chemistry | PLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[1][2] | Soft thermoplastic polyurethane at 82–85 Shore A[3][4][5] |
| Densityg/cm³ | 1.31 (Bambu Lab, ISO 1183) to 1.38 (Fiberlogy PLA Mineral, method not stated) — above plain PLA from the filler[2][1] | 1.11 (BASF Ultrafuse 85A) to 1.19 (NinjaFlex 85A), ISO 1183 / ASTM D792[5][3] |
| Typical priceUSD/kg | Mainstream 1 kg spools cluster near 21[6][7][8] | 1 kg-equivalent spools span 32–106; the middle of the market is about 90[9][10][3] |
| Price range across brandsUSD/kg | 11–32 across brands; budget house brands 11–19, Fiberlogy PLA Mineral 32[11][7][12] | 32–106 across brands; Siraya Tech Flex TPU 85A 32 at 1 kg, add:north TPU Pro Matte 85A 72, Recreus Filaflex 82A 90 at 500 g, Proto-pasta Clear Flexible TPU 90, 3DXTech 3DXFLEX 85A 96, NinjaTek NinjaFlex 106[13][9][10][14][3] |
| Market availability1–5 | Stocked by most mainstream brands[11][8][6] | Available from several mainstream brands[9][13] |
| Spool sizes & diameters | 1.75 mm; 1 kg spools plus spool-less refills[6][15] | 1.75, 2.85 and 3 mm; 0.5, 1 and 2 kg spools[9][13][3] |
| Typical applications | Display models and visible parts where a matte, non-reflective finish matters[2] | Soft-touch grips, seals, wearables and anything that must compress and rebound[3][4] |
| Diameter tolerance± mm | ±0.03 (Bambu Lab)[16] | Not documented |
| Printing Parameters | ||
| Nozzle temperature°C | 190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[2][1] | 200–220 (BASF Ultrafuse 85A, 210 typical)[5] |
| Bed temperature°C | 35–45 (Bambu Lab); 60 (Fiberlogy)[2][1] | 40 (BASF Ultrafuse 85A)[5] |
| Enclosure / chamber requirement1–5 | Open frame is fine[2][1] | Open frame is fine[5] |
| Part cooling fan | Fan on; Fiberlogy specifies 75–100 %[2][1] | Not documented |
| Bed surface & adhesion aid | Cool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[2][1] | PEI sheet or painter's tape; Polymaker warns TPU can over-stick and advises a glue stick as a release agent[17][18] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | 1.2–3.2 at the 15–40 mm/s BASF specifies on a 0.4 mm nozzle at 0.2 mm layer[5] |
| Warping tendency1–5 | None[2] | None[5] |
| Bed-adhesion difficulty1–5 | Sticks to anything[19] | Sticks to anything — Recreus states its 82A grade has excellent bed adhesion without a heated bed or additives[4] |
| Stringing / oozing tendency1–5 | Not documented | High — drying plus tuning needed[20][18] |
| Overall printing difficulty1–5 | Beginner — prints on any machine out of the box[2][1] | Advanced — enclosure, hardware upgrades, tuning; at this hardness the filament will not push through a Bowden tube[3][4] |
| Extruder requirement | Not documented | Direct drive only. NinjaTek calls its 85A grade ideal for direct-drive extruders and Recreus specifies direct-drive printers for 82A; BASF caps print speed at 15–40 mm/s with a nozzle of 0.4 mm or larger[3][4][5] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[21][2][1] | Brass fine indefinitely[22] |
| Abrasiveness1–5 | Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[1][2][23] | Non-abrasive[22] |
| Nozzle clog risk1–5 | Very low[21] | High — jams from moisture, heat creep or particles[20][18] |
| Heat-creep / jam sensitivity1–5 | Moderate — good heatbreak cooling needed; PLA softens below 60 °C[24] | Very high — softens in the cold zone readily; soft filament buckles between the drive gear and the melt zone[18][3] |
| Hotend requirement | No special hot-end required[19] | No special hot-end required, but a direct-drive extruder is (Simplify3D)[17] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 0.40 % saturated at 25 °C / 55 % RH[2] | Moderate — NinjaTek measures 0.22 % in 24 h (ASTM D570) and BASF specifies a 70 °C dry for at least 5 h[3][5] |
| Equilibrium moisture content at ~50 % RH% | 0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[2] | 0.22 after 24 h water immersion (NinjaFlex 85A, ASTM D570) — an immersion figure, not an equilibrium moisture content at 50 % RH[3] |
| Drying temperature & time | 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[2][1][25] | 70 °C for at least 5 h in a hot-air dryer or vacuum oven (BASF)[5] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[20] | Bubbling and popping at the nozzle, stringing and a rough surface[20] |
| Effect of moisture on strength | Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[20] | Polymaker groups TPU with the highly hygroscopic materials; wet TPU prints with poor layer adhesion and weak, brittle layers[20] |
| Storage requirement | Sealed with desiccant below 20 % RH; shelf life at ambient is long[23][19] | Sealed with desiccant; often kept in a dryer during the print[20] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 30 (printed XY, ISO 527, Bambu Lab); 35.1 on My Tech Fun bars for PolyTerra PLA[2][26] | 26 ultimate (NinjaFlex 85A, ASTM D638)[3] |
| Young's modulusMPa | 1960 (Bambu Lab, printed XY, ISO 527); Fiberlogy PLA Mineral quotes 3500 (ISO 527, specimen type not stated)[2][1] | 12 (NinjaFlex 85A, ASTM D638) — two orders of magnitude below any rigid filament; NinjaTek's 95A Cheetah reaches 26 by the same method[3][27] |
| Elongation at break% | 14.8 (printed XY, ISO 527)[2] | 650 at break (Filaflex 82A) and 660 (NinjaFlex 85A); BASF measures 600 in XY and 320 in ZX[4][3][5] |
| Flexural strengthMPa | 53 (printed XY, ISO 178) — 30 % below PLA Basic at 76[2][23] | Not documented |
| Flexural modulusMPa | 2360 (printed XY, ISO 178)[2] | Not documented |
| Charpy impact, notchedkJ/m² | 6.3 (printed XY, ISO 179, notched); unnotched 19.2[2] | Not documented |
| Other impact data | Izod 6.1 kJ/m² on My Tech Fun printed bars for PolyTerra PLA[26] | Not documented |
| Layer adhesion / Z tensileMPa | 22 (printed Z, ISO 527); flexural Z falls to 29 against 53 in XY; 12.9 on My Tech Fun layer-adhesion bars[2][26] | Not documented |
| Brittleness1–5 | Brittle — snaps with little warning[2] | Very ductile — bends far before failing[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | 29 Shore D / 85 Shore A (BASF Ultrafuse 85A, ISO 7619-1); 85 Shore A (NinjaFlex, ASTM D2240); 82 A nominal for Filaflex[3][5][4] |
| Creep resistance / sustained load1–5 | Poor — 12 mm bar sagged to 18.7 mm over 5 days at 1.25 kg[26] | Poor — no 85A creep test; a printed 95A TPU bar crept from 74.5 to 82.7 mm over 5 days at 1.25 kg, and softer grades creep more[28] |
| Fatigue / repeated-flex resistance1–5 | 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][24] | Excellent — living hinges viable[18] |
| Elasticity / flexibility1–5 | Rigid[2] | Rubbery / highly elastic[3][4] |
| Z strength as % of XY% | 73 by tensile, 55 by flexural (printed, Bambu Lab)[2] | 53 — BASF measures 320 % elongation at break in ZX against 600 % in XY[5] |
| Wear resistance & friction | Not documented | Abrasion 0.08 g mass loss over 10 000 cycles (NinjaFlex, ASTM D4060); 82 mm³ (BASF, ISO 4649)[3][5] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 58 (Bambu Lab) and 48 (Fiberlogy PLA Mineral), ISO 75 at 0.45 MPa[2][1] | Not documented |
| HDT at 1.8 MPa°C | 52 (ISO 75, 1.8 MPa)[2] | Not documented |
| Glass transition (Tg)°C | 61 (DSC)[2] | Not documented |
| Melting point / Vicat°C | 163 peak melt (DSC); Vicat 63 °C[2] | 216 melting (NinjaFlex 85A, DSC)[3] |
| Continuous service temperature°C | 54 — loaded bars begin to move at this temperature[26] | Not documented |
| Annealing response | 50–60 °C for 6–12 h; some prints deform or warp, and a forced-air oven is required[2] | Not documented |
| Flammability / UL 94 | Flammable; no UL 94 rating published by the major brands[23][30] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[24][31] | Good — years with some colour shift; Polymaker lists UV exposure among the conditions TPU withstands[18] |
| Chemical resistance | Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[30][24] | Withstands industrial solvents and UV exposure (Polymaker)[18] |
| Water / humidity resistance in service1–5 | Good — insoluble in water[23] | Not documented |
| Food contact | Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[24] | Not food safe without specific certification (Polymaker)[18] |
| Biodegradability / compostability | Industrially compostable only — needs sustained 55 °C; not home compostable[32][24] | Not biodegradable[18] |
| Recyclability | Mechanically recyclable; not accepted in household plastic collection[32] | Not accepted in household plastic collection[18] |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission[33] | Low hazard — minimal VOC and particle emission; TPU was not among the nine filaments in the chamber study[33] |
| Ventilation / filtration requirement1–5 | None needed in a normal room[33] | Open a window / occasional ventilation[33] |
| Post-Processing | ||
| Sanding & machining | Wet sanding — dry sanding heats the surface by friction and smears it[31][24] | Difficult to sand or smooth; Polymaker limits post-processing to trimming or tumbling[18] |
| Gluing & solvent welding | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[24][34] | Cyanoacrylate bonds TPU; no common solvent welds it[18] |
| Vapour / chemical smoothing | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[24] | No practical vapour smoothing[18] |
| Support material pairing | Support for PLA (Bambu Lab)[2] | Polymaker warns TPU supports are often very difficult to remove[18] |
| Dimensional accuracy & detail | Matte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[2] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[35] | DMF, DMSO, NMP and THF dissolve TPU; acetone, MEK and cyclohexanone are partial solvents. All laboratory reagents.[36] |
| Softened or crazed by | Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[35][37] | Toluene and benzene swell it up to +50 % by weight at 23 °C; esters swell it severely; ethanol and IPA soften it.[36] |
| Solvent welding & smoothing agent | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[38][37] | None practical — the true solvents (DMF, THF, NMP) are laboratory reagents and leave the joint swollen and weak.[36] |
