Creality CR-Silk 1.75mm PLA Filament 1kg (Silver): problems, parts and running costs

Checked: 2026-10-16

Summary

Owners report tuning and handling trouble rather than part failures: Creality publishes three different temperature and speed profiles for this filament, printed parts come out more brittle than standard PLA, and the soft filament can grind and clog in multi-material hubs. The only running cost is the filament itself, listed at $19.99 for a 1kg spool at Creality’s US store in October 2026, falling to $14.99 in 20-roll bulk. It is a good buy at $15 a roll or less for decorative prints, and weak above about $22.

Common problems and fixes

Conflicting official print profiles — Creality’s US parameter guide says 190-230 C nozzle, 50-60 C bed and 40-80 mm/s; its K1-series wiki says 230 C, 45 C and 120 mm/s with a 10 mm3/s flow cap; its silk PLA page says 200-240 C, 60 C and 30-100 mm/s. None is labelled the definitive profile. Run a temperature tower per spool and treat any single profile as a starting point. [1][2][3]
Brittle prints, thin parts break — a K1 Max owner reports silk pieces “breaking off all over the place” with the silk profile while Hyper PLA printed a full roll without issues; another owner calls silk far more brittle than standard PLA on thin pieces. Use standard PLA for functional parts. [4][5]
Inconsistent gloss and under-extrusion at stock settings — a forum user printing silk at 205-210 C and 60 C saw dull layers, slight under-extrusion and rough texture. The fix is a generic PLA/Silk profile plus calibration (temperature tower, flow, pressure advance), recalibrated per color because pigments change behavior. [6]
Grinding and clogs in AMS/CFS hubs — silk PLA is softer and easier to crush than normal PLA, which causes grind and clog issues in multi-material units; one user found shredded silk-additive ribbon wrapped around the extruder wheels. Watch hubs closely and dry the spool if feeding looks off. [7][8]
Heatbreak jams when run too hot — cross-brand guidance puts optimal silk temperatures around 190-215 C depending on brand and warns that overheating causes heatbreak jams. Print at the lowest feasible temperature. [9]
Stringing and bumps on outer walls — a Creality gold silk print on a Bambu Lab X1 Carbon came out stringy with bumps on the outer walls; responders suggested drying, flow calibration and checking Creality’s own spec temperatures. [10]
Dimensional tolerance is unpublished — Creality’s CR-Silk pages publish no tolerance; retailers list 0.03 mm and one specialist database lists ±0.02 mm, so the true figure is unverified. [11][12][13]

Parts and consumables

CR-Silk 1.75mm PLA 1kg spool (Silver) — listed at $19.99 against a $28.99 reference at Creality’s US store, October 2026, with bulk pricing of $16.99 (5 rolls), $15.99 (10) and $14.99 (20). The spool is 1 kg net, 1.29 kg gross, packed 210 x 210 x 75 mm, 12 spools per 16.5 kg carton; per-color item numbers exist at the wholesale portal (Golden 3301120001) but the Silver number was not published. This is the only consumable — standard 1.75 mm filament, no proprietary spools. [11][14]

No other replaceable parts or consumables are reported: the box contains the spool only, and no manual or technical data sheet was located. The US store offers 14-day returns and advertises an up-to-12-month warranty. [11]

Yearly running cost

The only running cost is the filament itself, plus the printer’s electricity. A 1 kg spool is $19.99 at Creality’s US store (October 2026), $14.99 per roll at the 20-roll bulk price, EUR 25.99 at the EU store and AUD 37.99 at the Australian store. There are no subscriptions or proprietary consumables. No owner data on how many rolls a typical user prints in a year was found.

When it is a good buy

At or below $15 a roll, the 20-roll bulk price of $14.99, it is reasonable for decorative printing where the glossy finish matters.
Between $16 and $22 it is fairly priced and matches the manufacturer’s own sale and regional pricing.
Above $22 it is weak unless a specific Creality colorway is required; a Czech retailer’s Gold-silver listing at 519 CZK, about $23, sits in that band.
Alternative: Numakers Silk PLA at $16.99 a spool, falling to $12.99 in bulk, is the better choice when you want a silk finish without the Creality brand. Standard PLA is the better choice for functional parts, because silk is more brittle.
