High Speed 3d Printer Filament | FAQs
1.What is the main difference between High-Speed (HS) PLA and standard PLA?
1.What is the main difference between High-Speed (HS) PLA and standard PLA?
The primary difference is the Melt Flow Index (MFI). HS-PLA is chemically modified to have a lower viscosity when melted, allowing it to flow up to 500% faster through the nozzle without causing under-extrusion.
2.Does high-speed printing require higher temperatures?
2.Does high-speed printing require higher temperatures?
Yes. Because the filament spends significantly less time in the "melt zone" at 500 mm/s, you often need to increase the nozzle temperature by 20°C to 30°C compared to standard settings to ensure the plastic is fully molten before it exits the nozzle.
3.How do I know if my filament has "absorbed" moisture?
3.How do I know if my filament has "absorbed" moisture?
You will hear popping or hissing sounds at the nozzle during printing. Visually, you’ll see "zits," stringing, or a rough surface finish on your parts. This is caused by water trapped in the plastic turning into steam.
4.Should I dry my filament even if it's brand new?
4.Should I dry my filament even if it's brand new?
Ideally, yes. Many filaments are water-cooled during manufacturing and may not be perfectly dry when vacuum-sealed. Drying new filament for 4–6 hours can eliminate 90% of "first-layer" frustration
5.What is the shelf life of a spool of filament?
5.What is the shelf life of a spool of filament?
If stored in a cool, dry place with desiccant, most filaments last 1–2 years. PLA is the most stable, while nylon and TPU can degrade faster if exposed to UV light or high humidity.
6.What is the maximum print speed supported by SUNLU High-Speed Marble PLA?
6.What is the maximum print speed supported by SUNLU High-Speed Marble PLA?
SUNLU’s High-Speed Marble PLA is optimized for "Next-Gen" speeds, supporting a printing velocity of up to 450mm/s while still maintaining its characteristic stone-like texture and appearance.
7.Can I get PETG that is optimized for high-speed printers?
7.Can I get PETG that is optimized for high-speed printers?
Yes, SUNLU has a High-Speed Matte PETG. It combines the heat resistance and durability of PETG with high-flow additives, and it features a matte finish to hide layer lines that might become more prominent during fast prints.
8.Does SUNLU offer bulk sizes for high-speed printing projects?
8.Does SUNLU offer bulk sizes for high-speed printing projects?
Yes. Recognizing that high-speed printers consume material much faster, SUNLU offers 3KG and 5KG large spools for High-Speed PLA. This reduces the frequency of spool changes during large-scale manufacturing.
9.Can SUNLU High-Speed filaments be used with the Bambu Lab AMS?
9.Can SUNLU High-Speed filaments be used with the Bambu Lab AMS?
Yes. SUNLU high-speed filaments are compatible with the AMS (Automatic Material System). They even sell an "AMS Heater" and specific spool sizes designed to fit perfectly within multi-material systems used for fast, colored printing.
