ELEGOO Silk PLA 3D Printer Filament 1.75mm Dual Color Black Purple 1KG: problems, parts and running costs

Checked: 2026-10-20

Summary

ELEGOO’s Silk PLA Black Purple spool is well specified on paper — 1.75 mm at +/-0.02 mm, 1 kg of filament, 164 C melting point — but the published detail is thin exactly where a buyer needs it: no nozzle temperature band for the silk variant, no filament warranty terms, and no independent diameter or print-quality test of the gradient. The only running cost is the spool itself, and comparable silk dual-color filament sells for $12.95 to $36.99 per 1 kg, so a yearly figure can only be given per kilo. It is a good buy at or below the low end of that band for decorative prints and a poor buy above the top of it.

Common problems and fixes

No published nozzle temperature range for the Silk variant — the manufacturer page confirms only a 164 C melting point and a 35-65 C bed range; the nozzle band for this silk variant could not be confirmed, and filament warranty terms are not stated either. Start from the 190-230 C range given for the standard PLA line or the 210-240 C a competitor lists for its own silk dual-color filament, dry the spool at 55-65 C for 6-8 h as that competitor also recommends, and calibrate before trusting a profile. [1][2][4]
Empty spool weight differs between ELEGOO product lines — the Silk page gives 174 +/- 5 g for the empty spool while the standard PLA page gives 154 +/- 10 g, so weighing a spool to judge how much filament is left only works if you subtract the 174 g figure. [1][2]
The US storefront title drops “Silk” — the US listing is titled as colored PLA without the word Silk even though the product sits in the Silk PLA category, so open the category listing and confirm the finish before ordering. [1]
“Clog-free” and low warp and shrinkage are unverified claims — no independent test, no instrumented diameter scan and no print-quality comparison were found; a third-party mirror of the product page adds less-tangle winding and a larger spool inner diameter, which is not a manufacturer specification. [1][3]
Desiccant, spool dimensions and spool material are unconfirmed for this variant — the filament is dried 24 hours and vacuum sealed with desiccant, but whether a desiccant packet ships in every unit, the spool dimensions, and whether the spool is plastic or cardboard are all open, while the PLA Plus line does list a cardboard spool option. [1][6]
The gradient’s repeat length is unpublished — the black-to-purple color transition runs along the strand, but nothing states how often the color shifts along a spool, so a short print can capture only one part of the gradient. [1]

Parts and consumables

ELEGOO Silk PLA 1.75 mm dual-color spool, 1 kg (Black Purple) — the only consumable; a 1 kg spool with a 174 +/- 5 g empty spool, used up as you print, with no replacement interval reported and no separately reported price for this variant. Comparable silk dual-color spools are $12.95 to $36.99 per 1 kg at the Eryone store, October 2026. [1][5]
Empty spool, 174 +/- 5 g — the carrier the filament is wound on; plastic or cardboard is unconfirmed, while the PLA Plus line lists a cardboard spool option. [1][6]

Yearly running cost

Not enough data for a computed yearly total, because ELEGOO’s own price for the Black Purple 1 kg spool could not be confirmed and no source gives an annual print volume. The only running cost is the filament: comparable silk dual-color PLA is $12.95 to $36.99 per 1 kg at the Eryone store, October 2026, so a yearly figure is your kilos printed multiplied by the per-kilo price you actually pay. There are no subscriptions, filters or other consumables, and the printer’s electricity does not change with the filament brand. [1][5]

When it is a good buy

At or below $12.95 per 1 kg — the low end of the Eryone silk dual-color band, October 2026, is the floor for this kind of filament; below it the Black Purple gradient is a cheap way to get a dual-color look. [5]
Above $36.99 per 1 kg — the top of that band, October 2026; above it you pay more than the market for the same 1 kg of dual-color silk and should switch brand. [5]
Compare any quoted price against the $12.95 to $36.99 per 1 kg band — ELEGOO sells the filament through its own US, CA, EU and UK storefronts, and the product page could not be read at check time, so no ELEGOO price was confirmed. [1]
Alternative: Anycubic PLA Silk Dual Color Black Blue — the better choice when you want a published print window, because it states 210-240 C and a 55-65 C dry cycle for 6-8 h where the ELEGOO page gives only the 164 C melting point. [4]
Alternative: standard PLA — the better choice when the gloss is not the point; ELEGOO’s standard PLA page publishes a 190-230 C printing range and a 154 +/- 10 g empty spool, while the PLA Plus page lists a cardboard spool option, none of which the silk page states. [2][6]
