Zi-Rui PLA 3D Printer Filament 1.75mm, Tri-Color Changing with Temperature | Pine Green to Light Orange to Yellow, Temperature Color Changing, Dimensional Accuracy +/-0.02mm, 1kg Spool

Product Details

• Temperature Activated Tri-Color Shift: This thermochromic PLA filament features a sensitive temperature color-changing effect. It appears Pine Green at temperatures below 31C, gradually turns Light Orange when the temperature exceeds 31C, and fully changes to bright yellow above 45C, bringing vivid and magical visual changes to your printed models. Note: Avoid prolonged direct sunlight exposure, as long-time UV radiation will accelerate color fading and weaken the temperature-sensitive discoloration effect
• Ultra-High Dimensional Accuracy: Designed with a standard 1.75mm diameter and strictly controlled tolerance within 0.02mm. The ultra-precise size consistency ensures uniform and stable filament feeding during long-term printing, effectively reducing printing errors and delivering delicate, smooth, and high-restoration 3D printing results
• Trouble-Free Smooth Printing Performance: Zi-Rui professional PLA filament is manufactured under strict industrial tolerance and premium quality standards. It achieves excellent molding performance with zero bubbles, no extrusion jamming, and no edge warping. The overall printing process is stable and smooth, greatly lowering the failure rate and bringing a worry-free printing experience for both beginners and professional users
• Premium Material & Extrusion Performance: The filament spool is neatly and orderly wound without tangling. The high-quality PLA material melts evenly and feeds continuously, effectively preventing nozzle blockage and extruder clogging. Reliable and consistent performance makes it a top choice for engineers, designers, and 3D printing enthusiasts who pursue high-quality printing works
• Standard PLA Printing Parameters & Tips: Recommended Printing Settings: Nozzle Temperature: 190C220C; Hot Bed Temperature: 40C60C; Printing Speed: 4090mm/s. For better molding and color stability, store the filament in a cool and dry environment. Keep the filament dry before printing to avoid layer cracks and poor extrusion caused by moisture absorption
• Wide Compatibility with FDM Printers: This 1.75mm PLA filament is universally designed to work seamlessly with most FDM 3D printers that accept standard 1.75mm diameter filament, ensuring broad compatibility across various printer brands and models for versatile printing applications
• Generous 1kg Spool Capacity: Each spool contains 1kg (2.2lbs) of premium PLA filament, providing ample material for multiple printing projects and extended printing sessions without frequent filament changes, making it suitable for both small detailed models and larger scale prints

Printing Zi-Rui PLA

Zi-Rui PLA in Green runs on the PLA profile below, and this listing is a 1kg spool. PLA is best suited to everyday prototypes, models, and indoor parts that won't face heat or heavy stress. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.

Ranges checked against Bambu Lab, Prusament and Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our PLA filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.

Nozzle Compatibility

This is an unfilled plastic, so it is not abrasive: a brass nozzle works and lasts, and so does hardened steel. With hardened steel, print about 5 to 10°C hotter.

Based on Bambu Lab and Prusa guidance. More in our nozzle types guide.
