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

Checked: 2026-10-16

Summary

CR-Silk Purple is a budget glossy PLA for decorative prints, and the problems owners report are the usual silk-PLA ones: a tradeoff between stringing and layer adhesion, fragile layers on functional parts, and occasional nozzle clogs. The only running cost is the filament itself, listed at $19.99 for a 1kg spool at Creality’s US store in October 2026. It is a fair buy at that price for figurines, vases and display pieces, and the wrong material for load-bearing parts.

Common problems and fixes

Stringing versus layer adhesion — a recurring silk-PLA tradeoff: one owner sums it up as “you either get poor layer adhesion or stringing; those are your choices”. No fix is reported beyond tuning; a hotter nozzle gives a shinier surface but more stringing. [1][2]
Fragile layers on functional parts — an owner printing functional RC parts reports silk PLA “layer adhesion always comes out very fragile”; silk’s advantage is appearance, not mechanical performance. Use PLA+ or PETG for load-bearing parts. [2][3]
First-layer bed adhesion — some users report bed adhesion issues with silk variants; the suggested fix is a higher first-layer bed temperature and a nozzle 5-10 C hotter for the first layer, with the warning that printing too hot dramatically increases stringing and blobs. [4]
Nozzle clogging — silk PLA clogging reports include one spool that clogged two nozzles at 210 C and another that left “tiny bits of silk clogging the nozzle”. Neither report is Creality-specific. [5][6]
Retailer spec sheets disagree — one data sheet lists bed 0-60 C and speed 40-100 mm/s, another lists 50-60 C and 40-80 mm/s, all citing manufacturer specs. Treat the ranges as starting points and run your own tests. [10][11]
No independent test data — no instrumented test from established outlets was found; one YouTube creator temperature-tower tested CR-Silk among six Creality filaments but disclosed the spool was sent by Creality. [9]

Parts and consumables

CR-Silk 1.75mm PLA 1kg spool (Purple) — $19.99 against a $28.99 compare-at at Creality’s US store, October 2026, with tiered bulk pricing of $16.99 (5 spools), $15.99 (10) and $14.99 (20). Vacuum-sealed bag with desiccant and a reusable bag; claimed compatible with 99% of FDM printers and 3D pens. The store advertises a 14-day return and up-to-12-month warranty. [7]
CR-Silk 2KG sample pack (8 x 250g spools) — $39.98 at Creality’s US store, October 2026; eight colors in small spools instead of one 1kg spool. [8]

No other replaceable parts or consumables are reported; it is a consumable filament with no user-serviceable parts.

Yearly running cost

The only running cost is the filament itself, plus the printer’s electricity. A 1kg spool is $19.99 at Creality’s US store (October 2026) and $14.99 per spool in 20-unit bulk; the 2KG sample pack of 8 x 250g spools is $39.98. There are no subscriptions or other consumables. No owner data on how much filament a typical user prints in a year was found.

When it is a good buy

At $19.99 for a single spool it is competitive for decorative printing; at the $14.99 bulk price the value case improves for high-volume decorative work.
A third-party marketplace listing has appeared at $14.99 for a 1kg silver spool; it is a marketplace mirror, not the official store. [12]
Alternative: PLA+ or PETG is the better choice for functional parts, because silk PLA’s advantage is appearance, not strength. [3]
