colorFabb LW-PLA Gray Silver 3D Printer Filament, 1.75mm Diameter, 750g Spool, Lightweight Material, Ideal for RC Planes, Matte Finish

Product Details

• Print ultra-lightweight parts with confidence and creativity. This lightweight filament uses active-foaming technology to expand inside the nozzle and turn your prints into feather-light creations — perfect for RC-models, cosplay props, or large structural shells. You can reduce weight by up to 65% compared to standard PLA. Set nozzle to ~230 °C (or around 200-260 °C depending on your flow and speed), reduce flow to ~35-40%, and print at 40-100 mm/s. Use this for large wings, display pieces or wearable parts and avoid heavy, bulky prints.
• Get flawless matte surfaces and ultra-low part weight with one spool. With LW-PLA you don’t just save weight — you also get a smooth, matte finish that’s easy to sand, trim, paint or finish. Ideal for model makers, hobbyists, engineers who care about aesthetics and function. Load the filament, calibrate your extrusion multiplier (because foaming increases volume), print at ~230-250 °C, monitor expansion, and use thicker layers or perimeter walls to speed up builds. Great for shells, lightweight housings, or display items where every gram matters.
• Transform your 3-D printing workflow with innovative foaming PLA that cuts weight and material cost. Whether you’re printing architectural models, prototype shells or drone frames, this filament gives you the efficiency of lighter parts and faster print times. The foaming allows use of bigger layer heights or reduced flow, meaning you need less filament per part. Tip: start at 220-230 °C, print flow at 60-70%, increase only if needed, and ensure good bed adhesion. For finer detail, switch to conventional flow and lower temps.

Printing ColorFabb PLA

ColorFabb PLA in Matte Grey runs on the PLA profile below, and this listing is a 0.75kg spool. PLA is best suited to light parts such as RC aircraft, cosplay props and large display pieces. 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 colorFabb, Polymaker and Bambu Lab data. Heat resistance is the heat deflection temperature (HDT). Read our LW-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.
