Silk PLA Filament 1.75mm Rainbow Tri-Color Gradient

Brand: Yiqiu3D · Fantasy builds live or die on the colour shift: a blue-violet gradient that breaks into bands halfway up a helmet ruins a prop that took days to print. This is the Blue Elf colourway, a silk rainbow in blue elf tones that runs through the strand, so the transition travels with the part instead of stepping across it. A silky PLA plastic surface finish, not metal. 1 kg net filament per spool at 1.75 mm.

  • Blue Elf leads a fantasy palette: the same family carries Silk Rainbow Rose
  • Cosplay and prop work is mostly post-processing
  • this grade takes some of it away. The gradient arrives on the plate with the sheen already there

Quick Answer

What makes the Blue Elf colourway different from a standard rainbow?

Blue Elf is a blue-led rainbow colourway: the strand shifts through blue and violet tones rather than sweeping the full spectrum, so printed parts read as cool and fantasy-toned under both daylight and display lighting. The material is PLA plastic with a silky surface finish - there is no metal pigment in it and no abrasive filler, so standard brass nozzles and standard PLA profiles apply. Nozzle window 200-225 °C.

Is it right for my project?

Best for: Suited to elegant homeware and lamp shades where the silk sheen catches light - available in 9 colours. Not ideal for: Avoid high-friction mating surfaces; a standard or matte grade performs better - available in 9 colours.

01 · Why this one

Product highlights

3 reasons

Blue Elf leads a fantasy palette: the same family carries Silk Rainbow Rose, Matte Rainbow Lollipop, Matte Rainbow Spring, Tri Color Matte Yellow + Blue + Pink and Silk Three Colors Gold + Silver + Copper, so a range, a diorama set or a cosplay commission can be colour-matched inside one supply line. Colour comes from the strand itself - one spool, one gradient, no filament swap and no purge tower - and the gold, silver and copper names are colour names on a PLA plastic spool.

Cosplay and prop work is mostly post-processing

this grade takes some of it away. The gradient arrives on the plate with the sheen already there, so there is no base coat to paint over and no polishing step for gloss, and a helmet or armour panel keeps its colour while you print the next section. It runs on standard PLA profiles on direct-drive and Bowden machines, so a build can move between printers mid-project.

What You Receive

A prop program needs the spec to hold: 1.75 mm round profile, 1 kg net filament per spool, a 200-225 °C nozzle window on standard PLA profiles, and tight even winding on a round spool. 3,358,819 units are in stock, so a 1000-piece program does not wait on a production slot, and every spool is vacuum-sealed with a desiccant pack before it goes into the export carton.

Frequently Asked Questions

What makes the Blue Elf colourway different from a standard rainbow?
Blue Elf is a blue-led rainbow colourway: the strand shifts through blue and violet tones rather than sweeping the full spectrum, so printed parts read as cool and fantasy-toned under both daylight and display lighting. The material is PLA plastic with a silky surface finish - there is no metal pigment in it and no abrasive filler, so standard brass nozzles and standard PLA profiles apply. Nozzle window 200-225 °C.
Will it run on my printer?
It is 1.75 mm round-profile filament for standard FDM printers, direct-drive and Bowden alike, so Bambu Lab, Creality and Prusa style machines take it on their usual PLA profile. No enclosure and no hardened nozzle are required, because the grade carries no abrasive filler. Large cosplay panels benefit from your usual PLA settings for cooling; no special profile is needed.
What print settings do you recommend?
The figure published for this grade is the nozzle window: 200-225 °C on standard PLA profiles, with your usual PLA cooling and retraction. On tall parts, keep the layer height uniform so the colour transition reads as one smooth shift. If a panel must match an earlier print exactly, print both sections in the same orientation at the same layer height.
What is the net weight and print capacity per spool?
1 kg net filament per spool, 1.75 mm round profile, on a round spool. The 1 kg is net filament only: the packed carton is heavier because it adds the spool, the vacuum bag and the box. That is the same working capacity as any other 1 kg 1.75 mm PLA spool, so a cosplay build planned in spools stays close to the estimate.
Which colourways are in this family, and is the colour stable between batches?
The lead colourway is Silk Rainbow Blue Elf, alongside Silk Rainbow Rose, Matte Rainbow Lollipop, Matte Rainbow Spring, Tri Color Matte Yellow + Blue + Pink, Tri Color Silk Blue + Green + Orange and Silk Three Colors Gold + Silver + Copper. Colour is controlled per production run against the colour code you approve, so a repeat order matches the first shipment - which matters when a helmet printed in March has to match a gauntlet printed in June.
What is this filament best used for?
Cosplay armour and props, figurines and busts, dioramas and tabletop scenery, display models and shelf pieces where the colour change is part of the value. It suits decorative, display and costume work. Do not use it for load-bearing brackets or hinges, and avoid outdoor and heat-exposed parts, where the sheen dulls and PLA softens; choose PETG or ASA for those duties.
How is the spool packed, and how should I store it?
Each spool is vacuum-sealed in a foil bag with a desiccant pack before it goes into the export carton, which is what keeps moisture off the strand in transit and in your workshop. Keep spools sealed until use, reseal the bag or move the spool to a dry box after a print, and dry the strand before a critical build if it has stood in humid air. Do not store it in direct sun or next to a heat source.
