Product Details
- Lightweight & Durable for Outdoor Projects Discover the freedom of printing large, strong, yet lightweight parts with LW-ASA. Ideal for RC planes, drones, and outdoor models where weight reduction is key. This filament expands when printed, reducing material use by up to 35%. Its UV and weather resistance make it perfect for sun-exposed applications. For best results, print in draft mode to allow controlled foaming and achieve maximum strength-to-weight ratio.
- Professional Surface Finish & Easy Processing LW-ASA delivers smooth matte surfaces with excellent layer adhesion. Its superior flow behavior ensures consistent extrusion and clean detailing, even at lower infill settings. Designed for reliable printing without warping or cracking, it’s a great choice for both prototypes and final-use parts. To achieve optimal print quality, experiment with extrusion multipliers and layer height to balance detail, strength, and weight perfectly.
- Technical Specifications & Print Settings Material: LW-ASA (Light Weight ASA) Diameter: 1.75mm ±0.05mm Glass Transition Temp: 105°C Recommended Nozzle Temp: 240–260°C Heated Bed Temp: 80–100°C Print Speed: 35–55 mm/s Density Reduction: up to 35% (with foaming) Weather & UV Resistant: Yes Supports: Easy to remove Tip: Use lower extrusion and slower speed for lightweight prints with excellent dimensional stability, ideal for functional parts and outdoor models.

Printing ColorFabb ASA
ColorFabb ASA in Natural runs on the ASA profile below, and this listing is a 0.65kg spool. ASA is best suited to UV-stable outdoor parts that need to survive sun and weather without yellowing. 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 ABS & ASA 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.
