This is SUNLU PETG refill filament in white — same strong, reliable prints without the extra plastic spool. Snaps right into a reusable spool, prints smooth, and keeps my setup cleaner (and my trash lighter). If you’re printing PETG and want a more sustainable option, refill rolls are honestly a no-brainer. #3DPrinting  #PETG  #MakerLife  #Sunlu  #spool

The SUNLU PLA+ Refill Filament is the budget-friendly, eco-conscious solution for makers who want high-quality prints without the waste of plastic spools. Designed for 3D printing enthusiasts and pros alike, this refill-style filament works perfectly with reusable spools or the SUNLU S2 dry box, making storage and swapping easy. Made with SUNLU’s enhanced PLA+ formula, this filament delivers improved toughness, better layer adhesion, and reduced warping compared to standard PLA. Whether you’re printing detailed miniatures, functional parts, or colorful models, this filament produces smooth, high-precision results with consistent flow. With tight dimensional tolerance (±0.02mm), it’s optimized for stable printing on most FDM 3D printers, including Creality, Anycubic, Prusa, and more. Less plastic, more print. Save money and reduce waste—without compromising on quality. #sunlu #3dprinting #ecofriendlyprinting #pla3dprint #makerspace
