How Long Does a 1kg PLA Spool Last? Real-World Breakdown

"How long will this spool last?" It's the most common question new makers ask. The answer depends on what you print. Here's a real-world breakdown.

What's in a 1kg spool? A standard 1 kg / 315 m spool of 1.75 mm PLA sounds like a lot—but it goes faster than you think. Let's break it down by project type.

Small prints (under 20g each)

• Keychains, small clips, desk organizers: 5–15g each
• You get 60–150 prints per spool
• These chew up filament surprisingly fast because of repeated skirt and brim

Medium prints (50–150g each)

• Figurines, phone stands, planters, boxes: 50–150g each
• You get 7–20 prints per spool
• This is where most makers live

Large prints (200–500g each)

• Cosplay props, enclosures, large vases: 200–500g each
• You get 2–5 prints per spool
• Infill and supports add significantly to weight

The math formula Your slicer tells you exactly how much filament each print uses. Check the preview before hitting print. Add up your monthly print weights, and you'll know how many spools you need.

Typical maker usage

• Casual printer (1–2 prints/week): 1 spool lasts 2–3 months
• Enthusiast (1 print/day): 1 spool lasts 2–3 weeks
• Production maker: multiple spools per week

Budget planning tip Buy 2 spools at a time in your most-used colors (black, white, gray). Keeps you covered without tying up money in colors you might not use.

Pro tip: Weigh your spool before and after printing. A 1kg spool with an empty weight of 200g means you started at 1200g. Weigh it next month, and you'll know exactly how much filament you've used.
