Get several colours from one spool with our rainbow PLA filament and multi-colour effects: gradients that shift as the print grows, chameleon shimmer, dual and tri-colour silk, glow and heat reactive colour change. Ideal for vases, figurines and gifts, with no filament swaps.

You do not need an AMS, a tool changer or manual filament swaps to print in more than one colour. Every spool here builds its effect into the filament itself. Gradient spools change colour along their length, so a print changes colour as it grows. Co-extruded spools run two or three colours side by side in one strand, so each face shows a different tone depending on your viewing angle, and the chameleon versions add a shimmer that shifts with light. Colour Change reacts to heat, and Glow in the Dark Rainbow adds a night-time glow to its daylight gradient.

Where each colour lands depends on model size, infill, layer height and your starting point on the spool, so no two prints match. Larger, taller models give the gradient room to develop, while a small print may show only one or two colours. Spiral vase mode suits these spools, as one continuous wall climbs steadily through the colours. Glow in the Dark Rainbow changes colour every 20-30 grams, so a 100g model passes through roughly three to five colours.
With co-extruded filament, orientation matters as much as the model. Curved, rounded surfaces show the most movement between tones, and rotating the same model on the build plate gives a different balance of colours. Tri-Colour Silk is especially striking on spiral vases.
Colour Change responds to touch and heat, so it suits toys and classroom demonstrations. Charge Glow in the Dark Rainbow under UV light, outdoors or with a UV lamp, for the strongest glow. Keep small printed toys away from young children, as they can be a choking hazard.
Most effects here print on a normal PLA profile: a 190-220°C nozzle, a 25-60°C bed and 60-90mm/s. The co-extruded silks are the exception. Silk Fusion and Tri-Colour Silk list a hotter 200-230°C and a slower 40-60mm/s, so give them their own filament profile, while Silk PLA Rainbow keeps the standard settings. Dry any spool left open at 40-45°C for 4-6 hours. See OzFDM PLA Silk Rainbow and Glow-in-the-Dark Filament: What You Need to Know for more.
If you do run an AMS, the product data lists PLA Rainbow, Chameleon Dual Colour and Tri-Colour Silk as AMS compatible, and Colour Change comes on a standard 200mm AMS compatible spool.
Every spool in this collection is a 1kg roll, so trying a few effects adds up quickly toward volume pricing: 5% off 3 or more rolls, 10% off 6 or more and 15% off 12 or more, mixed across any colours and materials. Spend over $299 and shipping is free Australia-wide, except to PO Boxes, with orders sent from Perth or Melbourne.
No. The colours are built into one continuous strand, so you load the spool like any other PLA and the effect appears as it prints. That applies to the gradient, co-extruded silk, chameleon, colour change and glow rainbow spools alike. An AMS only helps if you want to combine these effects with other filaments in the same print.
It depends on the product. Glow in the Dark Rainbow changes colour every 20-30 grams. For PLA Rainbow and Silk PLA Rainbow we do not list a section length, and where the colours fall varies with model size, infill, layer height and your starting point on the spool. Co-extruded, chameleon and colour change spools carry their colours along the whole strand rather than in sections.
Both run two tones through a single strand. Silk Fusion has a high gloss silk surface, and the colour you see depends mainly on the model's shape, orientation and viewing angle. PLA Chameleon blends complementary tones into a shimmering finish that shifts as light and viewing angle change. Silk Fusion also prints slower, at 40-60mm/s, while Chameleon runs at 60-90mm/s.
The model was probably too small for the gradient. A small print uses only a short length of filament, which may sit within a single colour section. Try a taller or larger model, print several copies on one plate so each layer uses more filament, or use spiral vase mode. Starting from a different point on the spool also changes which colours appear.
