Working with Ceramic-Filled Resin CF-STD
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.
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 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.

Ceramic-Filled Resin CF-STD — frequently asked
What is Ceramic-Filled Resin CF-STD used for?
Ceramic-Filled Resin CF-STD 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 CF-STD?
Ceramic-Filled Resin CF-STD 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 CF-STD 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 CF-STD be welded?
Not readily — weldability is rated not recommended (5/100). Thermoset — cannot be welded; join with cyanoacrylate, epoxy or UV-cure adhesive on abraded, IPA-clean surfaces.
What surface finishes work on Ceramic-Filled Resin CF-STD?
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.
Can Ceramic-Filled Resin CF-STD 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.
What is the maximum service temperature of Ceramic-Filled Resin CF-STD?
Ceramic-Filled Resin CF-STD 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.
