| Identity & Market | ||
| Base polymer / chemistry | PLA filled with wood powder — 10–18 wt% (Bambu Lab SDS); colorFabb woodFill uses a PLA/PHA base with recycled wood fibre[1][2] | Polyvinyl butyral — a printable thermoplastic whose surface can be smoothed with isopropyl alcohol instead of a hot solvent[3] |
| Densityg/cm³ | 1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[4][2][5] | 1.10 (Polymaker PolySmooth, ISO 1183); Prusament PVB 1.10[3][6] |
| Typical priceUSD/kg | 1 kg spools cluster near 25; counting the 0.5 kg specialty spools the middle of the market is about 34[7][8][9] | 1 kg-equivalent spools cluster near 80[10][11] |
| Price range across brandsUSD/kg | 14–76 across brands; SUNLU 14, ELEGOO 19, Bambu Lab 25, Prusament 44, Filament PM 49 on 0.5 kg spools, colorFabb 76[8][7][11][12][13][9] | 49–102 across brands; Polymaker PolySmooth 49 at 750 g, Prusament PVB 80–102 at 500 g[10][11] |
| Market availability1–5 | Stocked by most mainstream brands[7][8][12][5] | Available from several mainstream brands[10][11] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.6, 0.85 and 1 kg spools[12][5][7] | 1.75 and 2.85 mm; 0.5 and 0.75 kg spools[10][11] |
| Typical applications | Decorative and model-making prints that are sanded and stained like timber[4][2] | Display models and light guides where a layer-free surface matters more than strength[3] |
| Diameter tolerance± mm | ±0.03 (Bambu Lab)[4] | +/- 0.03 (Prusament PVB)[6] |
| Printing Parameters | ||
| Nozzle temperature°C | 190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[4][2] | 215 +/- 10 (Prusament PVB)[6] |
| Bed temperature°C | 35–45 (Bambu Lab); 50–70 (Fiberlogy)[4][5] | 75 +/- 5 (Prusament PVB)[6] |
| Enclosure / chamber requirement1–5 | Open frame is fine[4] | Open frame is fine[3] |
| Part cooling fan | Fan on[4] | 100 % part cooling (Prusament PVB)[6] |
| Bed surface & adhesion aid | Not documented | Smooth PEI sheet or satin sheet; Prusa states a brim is not generally necessary[6] |
| Warping tendency1–5 | None[4] | Not documented |
| Overall printing difficulty1–5 | Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[14][4] | Easy — minor profile tuning; it prints close to PLA[3] |
| Extruder requirement | Nozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[14] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | 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[14][15] | Brass fine indefinitely[3] |
| Abrasiveness1–5 | Moderately abrasive — wood fill[14] | Non-abrasive[3] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[14] | Moderate — needs dry filament and a clean nozzle; Prusa calls PVB very prone to absorbing moisture and requires a 60 °C, 4 h dry before every print[16][17] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[4] | Very high (>2 %) — 2.36 % equilibrium water absorption (Polymaker PolySmooth), above every PLA and PETG grade here[3] |
| Equilibrium moisture content at ~50 % RH% | 1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[4] | 2.36 equilibrium water absorption (Polymaker PolySmooth); 2.09 for PolyCast; Prusament PVB takes up 0.18 in 24 h and 0.35 in 7 days at 24 °C and 22 % RH[3][18][6] |
| Drying temperature & time | 55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[4][14] | Maximum 60 °C for 4-8 h depending on how wet the filament is (Prusament PVB)[6] |
| Symptoms when wet | Bambu Lab flags pre-drying and ventilation as specific requirements for this grade[14] | Not documented |
| Effect of moisture on strength | 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[17][4] | Polymaker publishes no dry-versus-conditioned figures; at 2.36 % equilibrium uptake the material has to be kept dry to print cleanly[3][17] |
| Storage requirement | Not documented | Sealed with desiccant[17] |

| Brittleness1–5 | Brittle — snaps with little warning[4] | Moderate[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Shore D 77 (Prusa Polymers method)[6] |
| Creep resistance / sustained load1–5 | 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[19][20][21] | Not documented |
| 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 and the wood filler cuts elongation and the parts snap without warning[22][4] | Not documented |
| Elasticity / flexibility1–5 | Rigid[4] | Rigid[3] |

| Thermal Properties | ||
| HDT at 0.45 MPa°C | 60 (ISO 75, 0.45 MPa)[4] | 68 (PolySmooth) and 67 (PolyCast), ISO 75 at 0.45 MPa; Prusament PVB 63 (ISO 75 at 0.45 MPa)[3][18][6] |

| Melting point / Vicat°C | 156 peak melt (DSC)[4] | Amorphous — no melting point; Vicat 70 (PolySmooth) and 67 (PolyCast), ISO 306[3][18] |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[23] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission[24] | Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[24] |
| Ventilation / filtration requirement1–5 | None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[14] | Open a window / occasional ventilation[24] |
| Post-Processing | ||
| Sanding & machining | Sands and stains like timber — the usual reason for choosing it[2] | Not documented |
| Vapour / chemical smoothing | Not documented | Isopropyl alcohol vapour smoothing is the point of the material — Polymaker markets PolySmooth for hands-free post-processing to a layer-free surface[3] |
| Support material pairing | Support for PLA (Bambu Lab)[4] | PolyDissolve S1 is rated for PVB (Polymaker)[25] |
| Dimensional accuracy & detail | Wood grain hides layer lines; colour darkens with nozzle temperature[4][2] | PolyCast is the investment-casting variant of the same chemistry — it burns out cleanly rather than being smoothed[18] |
| Solvents & Solubility | ||
| Soluble in | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[26] | Isopropyl alcohol dissolves it; Prusa describes PVB as soluble only in IPA, and it is not water-soluble.[16] |
| Softened or crazed by | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[26][27] | Not documented |
| Solvent welding & smoothing agent | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[28][27] | Isopropyl alcohol: brushed or sprayed on for speed, or several hours in IPA vapour for a glass-like surface.[27][16] |
