Ceramic-Filled Resin
also Rigid / Ceramic-Filled Resin
Ceramic-Filled Resin is a glass- or ceramic-particle-loaded photopolymer for SLA/DLP printing (GB/T 35022 family), where the mineral filler raises stiffness and dimensional stability and minimises creep.

Ceramic-Filled Resin grades and fills
Ceramic-Filled Resin is supplied in 4 conditions, soft to hard. CF-STD is the default FabDigit quotes; the values on this page are for it.
Compare all 4 grades and fillsHide
| Grade · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|
high-load sinterable ceramic slurry (alumina / silica, >50 wt% filler) | Choose only when the resin is a binder to be burned out — printed green parts are debound and sintered into a true technical ceramic. | 35 | 0.6 | 90 Shore D | |
High-modulus ceramic-filled resin | Pick when maximum stiffness and creep resistance in thin sections matter more than toughness (mould inserts, fixtures, flow channels). | 65 | 1 | 89 Shore D | |
High-temperature ceramic nanocomposite resin | For wind-tunnel models, hot-gas ducts and low-volume injection/vacuum tooling where high HDT plus stiffness is required. | 68 | 1.6 | 90 Shore D | |

What is Ceramic-Filled Resin?
Ceramic-Filled Resin is a glass- or ceramic-particle-loaded photopolymer for SLA/DLP printing (GB/T 35022 family), where the mineral filler raises stiffness and dimensional stability and minimises creep. Engineers specify it for rigid tooling and test hardware, in CF-STD, CF-10K, CF-HT and CER-SLURRY versions. Cured values are 69 MPa tensile strength, 5% elongation, 4.1 GPa modulus, 85 Shore D and 1.6 g/cm³, with service to 80 °C. The filler makes parts brittle and abrasive to tooling, and bare surfaces yellow in sunlight; use an unfilled tough resin where impact resistance matters more than stiffness. Ceramic-Filled Resin has a density of 1.6 g/cm³ (0.0578 lb/in³), heavier than 92% of polymer grades. Its glass-transition temperature is 90°C (194 °F). Ceramic-Filled Resin has a tensile strength of 69 MPa (10 ksi), stronger than 75% of polymer grades. Elongation at break is 5% and the elastic modulus is 4.1 GPa (0.595 Msi).

Working with Ceramic-Filled Resin
Is Ceramic-Filled Resin easy to machine?
Machines and drills cleanly but the ceramic filler is abrasive — use carbide/diamond tooling, light cuts, sharp geometry to avoid edge chipping, and dust extraction.
Can Ceramic-Filled Resin be welded?
Thermoset — cannot be welded; join with cyanoacrylate, epoxy or UV-cure adhesive on abraded, IPA-clean surfaces.
Can Ceramic-Filled Resin be formed, bent or molded?
Printed on SLA/DLP at 25–35 °C tank temperature; stir/agitate to prevent filler settling, keep layers ≤100 µm, and thermal post-cure (e.g. 60–80 °C UV oven, high-HDT grades up to 130–160 °C) to reach datasheet stiffness and HDT.
Ceramic-Filled Resin chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| urethane/epoxy acrylate oligomerbackbone; sets Tg and toughness | 30 – 55 | 42 |
| acrylate/methacrylate reactive diluentviscosity control, crosslink density | 15 – 35 | 25 |

What surface finishes work on Ceramic-Filled Resin?
Sands and bead-blasts well to a uniform matte; prime-and-paint or lacquer for appearance and UV protection, since bare parts yellow and embrittle in sunlight; no plating without a conductive base coat.

Ceramic-Filled Resin — frequently asked
What is Ceramic-Filled Resin used for?
Ceramic-Filled Resin is typically used for rigid jigs and fixtures, wind-tunnel models, high-stiffness enclosures and manifold/flow test parts. In short: stiffest photopolymer option; low-creep dimensional stability; abrasive, brittle filler.
What is the tensile strength of Ceramic-Filled Resin?
Ceramic-Filled Resin has a typical tensile strength of 69 MPa (10 ksi) — stronger than 75% of polymer grades. Strength varies by condition: see the 4 listed tempers.
Is Ceramic-Filled Resin easy to machine?
Reasonably — machinability is rated fair (48/100, worse than 75% of polymer grades). Machines and drills cleanly but the ceramic filler is abrasive — use carbide/diamond tooling, light cuts, sharp geometry to avoid edge chipping, and dust extraction.
Can Ceramic-Filled Resin be welded?

What is the maximum service temperature of Ceramic-Filled Resin?
Ceramic-Filled Resin is rated for continuous use to about 80°C (176 °F), and briefly to 110°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
