RepRapper REP-DUALPLA-1.75MM-4x250G-PACK-A Dual-Color PLA Filament, 4 Spools

Dual-color coextrusion gives this PLA filament two colors along the strand, adding a changing color effect to suitable 3D prints.

This four-spool set pairs matte and silk finishes, so you can choose a look for decorative models, small projects, or 3D pen work.

Each spool contains 250 g of 1.75 mm filament. The assortment includes four red/blue and purple/green combinations.

What matters most

The color is built into the filament through dual-color coextrusion, rather than added as a separate finishing step. The manufacturer notes that printed parts can look different from different viewing angles, making the material a distinctive choice for decorative pieces such as vases and display models. Matte and silk options offer two different finishes across the set.

The pack contains Matte Red/Blue, Matte Purple/Green, Silk Red/Blue, and Silk Purple/Green. Four smaller spools make it easy to try each color pairing on a modest project, test a design, or switch between finishes without committing to one large spool. PLA is the listed material.

Customer feedback often highlights the color combinations and appearance, including the filament’s shifting visual effect. Reports on printability and quality are mixed, some users describe successful prints, while others mention print issues, including brittleness or clogging. Treat each pairing as a material to dial in for your printer and project rather than assuming identical results across setups.

Size & fit

This filament has a 1.75 mm diameter and is intended for FDM 3D printers that accept that filament size. Check your printer’s filament requirements before loading it. The four 250 g spools are also suited to smaller prints and color trials, where a full-size spool may be more material than the project calls for.

Practical tips

The suggested nozzle temperature is 180–220°C, with a bed temperature of 40–60°C and a print speed of 40–100 mm/s. These are starting ranges, adjust settings to suit your printer and the model you are printing. The product guidance recommends drying the filament at 50–60°C for 6–8 hours before printing each time.

For a decorative print, choose a model with visible curved or angled surfaces so the dual-color appearance can be seen from different viewpoints. A small test print can also help you assess the finish and settings before using a spool on a larger design.
