Creality CR-PLA Carbon 1kg: problems, parts and running costs

Checked: 2026-10-16

Summary

A 1.75 mm, 1 kg black spool of PLA filled with 15% carbon fiber, giving stiff, matte, low-warp parts at standard print speeds. The practical problems are abrasive nozzle wear, general brittleness reported for Creality PLA, and moisture uptake that needs drying. It is a consumable with no parts; running cost is the spools themselves plus a hardened nozzle.

Common problems and fixes

Nozzle wear — Creality warns that composite filaments increase nozzle wear and should be printed with abrasion-resistant or high-hardness nozzles, and independent coverage confirms carbon fill abrades brass nozzles. The fix is a hardened or ruby nozzle; that nozzle is the hidden cost of this cheap spool. [1]
Brittleness — r/Creality and r/3Dprinting owners call Creality PLA incredibly brittle, with one thread describing Z-axis brittleness and z-banding from day one. The complaints are about Creality PLA generally, not this carbon variant specifically, so confirm with a test spool if your printer is finicky. [1]
Moisture uptake — a Creality forum thread on Hyper PLA turning super-brittle after drying traced the brittle section to the first ~300 mm exposed to moisture. Creality’s drying guide groups PLA and PLA-CF and recommends drying at 55 °C for 8–12 h when ambient humidity exceeds 50%; a community profile lists 55 °C for 8 h. [2]
Stiffer, not stronger — independent testing (All3DP, Fabbaloo) found CF-PLA is not stronger in tension than plain PLA and is weaker along layer lines, with lower impact strength and elongation. Read the store page’s “high hardness, strong rigidity” wording as stiffness and matte finish; pick a different material if strength is the goal. [1]

Parts and consumables

No replaceable parts. The spool is the consumable: 1 kg of filament, 1.75 mm diameter, black. The wear item is the printer’s nozzle, not the spool. Damaged prints cannot be repaired, only reprinted.

Yearly running cost

Cost of the spools you print plus one hardened nozzle if your printer ships with brass. Creality’s store lists the spool at $19.00 (compare-at $28.99), with volume pricing at $16.15 each for 5, $15.20 for 10 and $14.25 for 20. Drying equipment helps but is not mandatory for PLA. The Creality store page lists a 14-day return and refund window and up to a 12-month warranty.

When it is a good buy

At $19 per kg from Creality’s own store (October 2026), CR-PLA Carbon is priced near or below many plain-PLA spools, which makes it a low-risk way to try carbon-filled PLA for stiff, matte, non-heat-critical parts on a standard-speed printer. The price advantage holds up to roughly $25–30 per kg; above that, better-documented CF-PLA from dedicated material brands (All3DP’s reference CF-PLA runs about $35 per kg) is easier to justify. The alternative from the same brand: Creality’s Hyper PLA-CF, a 4% carbon fiber product rated to 300 mm/s, is the better pick for high-speed printers.
