KOSEN PLA 3D Printer Filament PLA Flex Filament 1.75mm, Dimensional Accuracy +/- 0.02 mm, Neatly Wound 3D Printing Filament Fit Most FDM 3D Printers, 1kg Spool (2.2lbs) (Nude)

Product Details

• [UPGRADE FROM BASIC PLA] Think of KOSEN PLA Flex as PLA 2.0—combining the familiar ease of PLA with improved toughness, reduced brittleness, and more dependable everyday performance. It is a toughened PLA filament designed for stronger prints, not a soft or rubber.
• [BEGINNER-FRIENDLY, EASY PRINTING] KOSEN PLA Flex melts and flows smoothly with less complicated tuning, helping beginners achieve reliable results while giving experienced makers consistent performance. Recommended nozzle temperature: 190–230°C; heated bed: 45–60°C. Actual settings may vary by printer and model.
• [TOUGHER, LESS BRITTLE PRINTED PARTS] Engineered to better withstand bending, handling, and accidental impacts, KOSEN PLA Flex helps reduce the cracking and snapping commonly associated with standard PLA. Ideal for functional parts, toys, brackets, prototypes, and frequently handled models.
• [IMPROVED HEAT STABILITY] With a tested heat deflection temperature of 56°C, this upgraded PLA provides dependable shape stability in warmer everyday environments. It offers greater versatility for practical prints while retaining the dimensional stability and easy printability expected from PLA.
• [PRECISE DIAMETER, RELIABLE FEEDING] Manufactured with a consistent 1.75 +/- 0.02mm diameter and neatly wound to support smooth feeding, steady extrusion, and clean surface quality. Each 1kg spool fits most 1.75mm FDM 3D printers for dependable printing from the first layer to the finished model.

Printing KOSEN PLA

KOSEN PLA in Beige 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.
