2 selected · all documented properties
| Property | PMMA (acrylic)ENGINEERING | Break-away supportSUPPORT |
|---|---|---|
| Market snapshot | ||
| Listing priceUSD/kg; dated snapshots | $49.99/kg median; $49.99–$49.99/kg across 1 dated product listings | $42.49/kg median; $26.00–$79.98/kg across 4 dated product listings |
| Identity & Market | ||
| Base polymer / chemistry | Poly(methyl methacrylate) — acrylic, sold for 3D printing as a transparent glass substitute[1] | Break-away support compounds matched to a specific model material — Polymaker sells separate grades for PLA and for PA12[2][3] |
| Densityg/cm³ | Not documented | 1.22 (PolySupport for PLA) and 1.29 (PolySupport for PA12), ISO 1183[2][3] |
| Typical priceUSD/kg | 1 kg spools cluster near 50[4] | 1 kg-equivalent spools span 26–80; the middle of the market is about 45[5][6][7] |
| Price range across brandsUSD/kg | 50 at Push Plastic's 1 kg listing; 3 kg spools run the same per kilogram[4] | 26–80 across brands and grades; IEMAI 3D E-REMOVE 26, Polymaker PolySupport for PLA 40 at 750 g, YXPOLYER 45, PolySupport for PA12 80 at 500 g[5][6][7] |
| Market availability1–5 | Special order, 1–2 makers worldwide[4] | Available from several mainstream brands[5][8] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 1 and 3 kg spools[4] | 1.75 and 2.85 mm; 0.5 and 0.75 kg spools[5] |
| Typical applications | Transparent covers and light guides where PC's yellowing or cost rules it out[1] | Support that peels off by hand, avoiding the moisture handling and dissolution time that soluble supports demand[2] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 220–230 (PolySupport for PLA)[2] |
| Bed temperature°C | Not documented | 25–60 (PolySupport for PLA)[2] |
| Enclosure / chamber requirement1–5 | Not documented | Open frame is fine[2] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | 4–12 at Polymaker's 50–150 mm/s on a 0.4 mm nozzle at 0.2 mm layer[2] |
| Overall printing difficulty1–5 | Not documented | Easy — minor profile tuning[2] |
| Extruder requirement | Not documented | A second extruder or a tool changer[2] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Not documented | Brass fine indefinitely[2] |
| Abrasiveness1–5 | Not documented | Non-abrasive[2] |
| Nozzle clog risk1–5 | Not documented | Moderate — needs dry filament and a clean nozzle; Polymaker specifies a 55 °C dry for the PLA grade and warns brass nozzle life falls to about 9 h on the PA12 grade[2][3] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Not documented | Moderate — 0.64 % equilibrium water absorption (PolySupport for PLA)[2] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.64 equilibrium water absorption (Polymaker PolySupport for PLA)[2] |
| Effect of moisture on strength | Not documented | Not a structural material; no dry-versus-conditioned data is published[9] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 43 (ISO 75, 0.45 MPa, PolySupport for PA12). Polymaker's sheet prints a higher figure at the higher load, which is physically inverted; treat both HDT numbers as approximate[3] |
| HDT at 1.8 MPa°C | Not documented | 53 (ISO 75, 1.8 MPa, PolySupport for PA12) — printed above the 0.45 MPa figure on Polymaker's own sheet, which cannot be right; treat both as approximate[3] |
| Melting point / Vicat°C | Not documented | Vicat 171 (PolySupport for PA12, ISO 306)[3] |
| Environment & Chemical | ||
| Electrical & ESD properties | Not documented | Surface resistance above 10^13 ohm/sq (ASTM D257, THERMAX HTS2 and MTS1)[10][11] |
| Health & Safety | ||
| Fume toxicity1–5 | Not documented | Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[12] |
| Ventilation / filtration requirement1–5 | Not documented | Open a window / occasional ventilation[12] |
| Post-Processing | ||
| Support material pairing | Not documented | This is the support material. Polymaker publishes an adhesion matrix per model material, from very good to unusable, because break-away supports only work against the polymer they were matched to[2][3] |
| Solvents & Solubility | ||
| Soluble in | Acetone, MEK, ethyl and butyl acetate, THF, chloroform and carbon tetrachloride dissolve it; the last two are laboratory reagents.[13] | None — break-away support is removed mechanically; 3DXTech lists no water or solvent route for it.[14] |
| Softened or crazed by | Alcohols, aliphatic hydrocarbons, oils and phthalate plasticisers craze it, and the threshold falls as stress rises.[13] | Not documented |
| Solvent welding & smoothing agent | Dichloromethane acrylic cement (IPS Weld-On 3): 2–5 min soak, 17.2 MPa lap shear at one week. Controlled carcinogen.[15] | None — there is no solvent to weld or smooth with.[14] |
Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
