Glossy silk-look filament for display pieces, decorative prints, and bold visual finishes.
Shop collectionLineBoss filament is 1.75mm material on standard 1 kg spools and is intended for common FDM setups, including Bambu A1, P1, P2, X1, and H2 series printers. For AMS jobs, verify spool clearance before leaving a long multi-color print unattended.
PLA usually prints well out of the sealed bag. Dry PETG, TPU, nylon, PC, or any spool that has been open in a humid room before critical prints.
Yes. Email support@linebossfilament.com with your printer model, material, nozzle size, bed surface, and the issue you are seeing. We can suggest starting temperatures, fan settings, speed changes, and drying steps.
Start with one spool. If it does not behave on a sane baseline profile, contact us and we will help tune it or make it right.
Treat printed parts as non-food-contact unless you validate the full material, colorant, nozzle, printer, and finishing process for your specific use.
Pause before a long print, take a photo of the spool path or moisture symptoms, and contact support. We will help identify whether it is feed path, storage, drying, or a spool issue.
