Creality CR-Silk 1.75mm PLA 3D Printing Filament 1kg (Golden Red): problems, parts and running costs

Checked: 2026-10-17

Summary

Owners of the Golden Red CR-Silk spool mostly fight silk-PLA handling rather than printer hardware: wet filament that balloons and fails partway through a print, heat-creep clogs, and shine that only comes right after per-color flow calibration. The 35 MPa tensile and 67 MPa bending figures come from a single retailer listing and are unverified. Keeping it running costs only the filament itself plus an optional dryer, and at $19.99 direct from Creality (October 2026) it is a reasonable buy for decorative prints; above about $30 it is not.

Common problems and fixes

Wet filament failing prints partway — r/3Dprinting answers describe wet silk expanding and ballooning until the print fails partway, with heatsink cooling-fan placement and per-color flow rate as the fixes. Creality’s own troubleshooting guidance is to dry PLA at 40–45 °C for 4 hours when humidity is suspected. The store lists a 14-day return and an up-to-12-month warranty for the spool; these threads are user fixes, not warranty claims. [11][13][1]
Heat creep and nozzle clogs — an r/3Dprinting thread on silk PLA clogging reports the hotend softening filament in the extruder; the owner resolved it by increasing hotend cooling. Silk PLA is more sensitive to heat creep than standard PLA, so better hotend cooling is the workaround. [9]
Pieces breaking off mid-print — an r/Creality report of printing Creality silk PLA on a K1 Max silk profile describes pieces breaking off, while Hyper PLA printed without issues on the same printer; the fix is to tune the profile for silk rather than reuse a standard-PLA one. [10]
Inconsistent shine and under-extrusion — a Creality forum thread reports uneven shine, slight under-extrusion in some layers and a rougher texture than expected after switching from standard PLA; the advice there is per-color calibration, because pigments and additives change behavior between colors. [12]
Two different speed guides from Creality — the parameter guide caps CR-Silk at 40–80 mm/s with 50 mm/s recommended, while the K1C wiki table lists PLA-silk at 230 °C, a 45 °C bed, 120 mm/s and 10 mm³/s maximum flow; the wiki row is a high-speed-printer preset, so use the generic range on standard printers. [2][3]
Diameter tolerance listed two ways — Creality and the SpoolScout data sheet state ±0.02 mm, while retailer listing text advertises ±0.03 mm; All3DP reports that Thomas Sanladerer confirmed the ±0.02 mm tolerance for Creality PLA. Check the spool with calipers on arrival. [5][7][8]

Parts and consumables

CR-Silk 1 kg spool (item 3301120009) — the only consumable; $19.99 at the Creality US store (October 2026). There is no replacement interval: a spool is consumed as you print. [1][6]

Yearly running cost

The only recurring consumable is the filament itself — $19.99 per 1 kg spool at the Creality US store (October 2026) — with no subscriptions and no proprietary spool lock-in for 1.75 mm PLA. A typical yearly spend is the number of spools used times the per-spool price, and the sources carry no printing-volume data: Not enough data. [1][2]

When it is a good buy

$19.99 at Creality US store (October 2026) — the direct price, against a $28.99 compare-at; reasonable at or below about $20 for decorative prints where the finish matters. [1]
$24.99 at Newegg, third-party seller Jaspertronics LLC (October 2026) — fair value, but above the Creality direct price, so direct is the better buy. [8]
$21.85 at Creality VIP Mall (October 2026) — the international listing, in the same fair-value band as the Newegg seller. [4]
€25.99 at Creality EU store (October 2026) — against a €36.99 compare-at, for shoppers in the EU store’s region. [14]
Above about $30 — poor value for a decorative PLA with no independent measured data; silk PLA brands with more community history become the better choice.
Creality Hyper PLA — the better choice when a print has to survive handling: in the r/Creality report, Hyper PLA printed without issues on the same K1 Max where CR-Silk pieces broke off. [10]
