IIID Max - High Speed PLA+ Filament 1.75mm 1kg

IIID Max High Speed PLA+ — Print Faster Without Sacrificing Quality

The IIID Max High Speed PLA+ Filament 1.75mm is engineered for the new generation of fast 3D printers. If you own a Bambu Lab X1C, P1S, Creality K1, or any machine designed for high-speed printing, this filament is built to keep up — delivering clean, detailed prints at speeds up to 300mm/s without sacrificing layer adhesion or dimensional accuracy. Available in 36 colors including standard, fluorescent, and matte finishes, each 1kg spool is vacuum-sealed for moisture-free performance right out of the bag.

High Speed PLA+ is formulated for rapid extrusion and quick cooling, which means it holds its shape even when your printer is pushing aggressive speeds. The result: dramatically reduced print times without the quality compromises you might expect. Whether you are running a print farm, prototyping at speed, or simply tired of waiting hours for a single model, this filament transforms your workflow.

High Speed vs. Classic PLA+ — Which One Should You Choose?

Both formulations produce excellent PLA+ prints. The key difference is speed. Classic PLA+ is optimized for standard printers running 40-100 mm/s — it is slightly less expensive and available in a wide color range. High Speed PLA+ is engineered for printers running 150-300+ mm/s, with a formulation that handles rapid extrusion and cooling without delamination or loss of detail. If your printer supports high-speed profiles, this filament unlocks its full potential.

Key Specifications

Recommended Print Settings

For high-speed printers: start at 210-220°C nozzle / 60°C bed / 200mm/s and work your way up. Many users run this filament at 250-300mm/s with excellent results once dialed in. For standard-speed printers, use the same settings as regular PLA (200°C / 60°C / 60mm/s) — the filament performs perfectly at lower speeds too.

Use a 0.4mm nozzle for general use or a 0.6mm nozzle if you want to maximize speed further. Standard brass nozzle works fine — no hardened nozzle needed. Enable cooling fan at 80-100% for best overhang performance.

Color Options

This product is available in 36 colors spanning the full spectrum, including 4 fluorescent colors (Blue, Green, Orange, Red) for high-visibility applications, 4 matte finishes (Black, Graphite, Mystic Purple, White) that hide layer lines, and specialty colors like Vintage Brass and Crystal for unique creative projects.

Pro Tips for High Speed Printing

Moisture is the #1 enemy of fast printing. At high speeds, even minor moisture absorption causes micro-bubbles that show up as surface roughness and weak layer bonds. If you print frequently, consider a filament dryer or dry box. For occasional use, keep spools sealed when not on the printer. If you hear any crackling or popping from the nozzle, dry the spool at 45-50°C for 4-6 hours before continuing.
