FAQs About 1kg Filament
How many models can I print with one 1kg spool?
It depends on part size, infill, and wall settings. A small model, such as a phone stand, might use 30–60 g, so you could print 15–30 of those from a 1 kg spool. A mid-sized model, approximately 5–6 inches tall, can weigh 120–250 g, which translates to about 4–8 pieces per spool. Check slicer estimates for a more exact count before you start.
What length of filament is in a 1kg spool?
For 1.75 mm filament, most 1 kg spools hold about 330–400 meters, depending on material density. PLA is usually around 330–340 m, PETG a little less, and ABS can be closer to 380–400 m. For 2.85 mm filament, the length is much shorter, typically 110–130 m. Always check the manufacturer's specs for the exact number.
Is a 1kg filament a good size for print farms?
Yes, 1 kg spools are a practical standard for farms because they fit most holders and profiles and are easy to source in bulk. They support long prints without constant swaps, which helps uptime and scheduling. For very high-volume parts, 2–3 kg spools can further reduce changeovers. Use runout sensors and consistent suppliers to keep production steady.
What materials are available in 1kg spools?
Most brands offer PLA, PETG, ABS, ASA, nylon, TPU, and carbon-fiber-reinforced blends in 1 kg sizes. You can choose based on strength, heat resistance, flexibility, or ease of printing. Siraya Tech offers carbon fiber blends, nylon filaments, flexible TPUs, and classic ABS in convenient 1 kg sizes. Match the material to your part’s job and environment.
