IIID Max - Classic PLA+ Filament 1.75mm 1kg

IIID Max Classic PLA+ Filament — Reliable Prints, Every Time

The IIID Max Classic PLA+ Filament 1.75mm is our proven workhorse for everyday 3D printing. Formulated with enhanced toughness and improved layer adhesion over standard PLA, this PLA+ filament delivers consistent, high-quality results across a wide range of printers — from entry-level Ender 3 and Ender 3 V2 to advanced Bambu Lab and Creality machines. Available in 30+ colors, each 1kg spool is precision-wound and vacuum-sealed with desiccant so it arrives ready to print.

Classic PLA+ sits in the sweet spot between easy printability and real-world strength. It prints at low temperatures with minimal warping, making it a dependable choice for prototypes, decorative models, educational projects, cosplay pieces, and functional household items. If you want the PLA filament that just works — this is it.

What Makes Classic PLA+ Different from Standard PLA?

Standard PLA can be brittle under impact. Our Classic PLA+ uses a modified formulation that improves toughness and reduces the likelihood of cracking or shattering under stress. You still get the same easy printing experience — low temps, minimal warping, great surface finish — but with parts that hold up better in real use. The ±0.03mm diameter tolerance ensures smooth, consistent extrusion without jams or uneven layers.

Key Specifications

Recommended Print Settings

Start at 200°C nozzle / 60°C bed and adjust based on your printer. Classic PLA+ works well with both direct drive and Bowden extruders. Use a standard brass nozzle — no hardened nozzle required. For best surface quality, print the first layer at 20-30 mm/s, then increase to your preferred speed. A light fan (80-100%) helps with overhangs and bridges.

Tips for Best Results

Storage matters. Even though PLA is less sensitive to moisture than PETG or TPU, long exposure to humidity can degrade print quality. If you notice stringing, rough surfaces, or popping sounds during printing, your spool may have absorbed moisture. Drying it at 45-50°C for 4-6 hours typically restores performance. When not in use, store your spools in a sealed bag or dry box with desiccant.
