A farm that prints 100 kg of filament a month needs this many spools — and the same number of spool changes.
| Spool size | Spools per 100 kg (= spool changes per month) | Spool changes per year |
|---|---|---|
| 1 kg | 100 | 1200 |
| 5 kg | 20 | 240 |
| 10 kg | 10 | 120 |
| 15 kg | ≈ 7 | 80 |
Based on 100 kg per month; a 15 kg spool needs about 93 % fewer changes than 1 kg spools.
What 1 kg spools really cost a print farm
Every 1 kg spool ends with a remainder that is too short for the next part. It either becomes waste or forces a spool change mid-print, which can leave a visible line on the part or ruin the print. Enter your own numbers:
10 kg spools compared with 1 kg spools, using the values on the left.
| Spool size | Whole parts per spool | Leftover per spool | Leftover per year | Spool changes / empty spools per year |
|---|---|---|---|---|
| 1 kg | 1 | 200 g (20 %) | 480.0 kg | 2,400 |
| 5 kg | 6 | 200 g (4 %) | 96.0 kg | 480 |
| 10 kg | 12 | 400 g (4 %) | 96.0 kg | 240 |
| 15 kg | 18 | 600 g (4 %) | 96.0 kg | 160 |
No seam lines, no failed prints
With an 800 g part, a 1 kg spool leaves 200 g — not enough for another part. Changing spools mid-print risks a visible line or a failed print. A 10 kg spool prints 12 whole parts in a row.
Five times less leftover
The leftover on a 10 kg spool is 400 g per 10 kg (4 %) instead of 200 g on every 1 kg spool (20 %).
90 % fewer empty spools
Every 1 kg spool leaves an empty spool and packaging behind. A 10 kg spool replaces ten of them, a 15 kg spool fifteen.
Why big spools for a farm
Less downtime
A 10 kg reel replaces ten 1 kg rolls — ten fewer changes and ten fewer overnight runs stopped by an empty reel.
One batch, one colour
Large reels come from a single production batch, so parts printed on different machines match.
Lower cost per kilogram
Less packaging and fewer cores mean a lower price per kg than retail 1 kg rolls.

What customers say about CROFIL filament
Real reviews of our 1 kg CROFIL spools — the same material we produce on 5, 10 and 15 kg spools.

Frequently asked questions
Will a 5, 10 or 15 kg spool fit my printers?
Large spools are used with an external spool holder or a bulk feeder next to the printer, feeding through a PTFE tube. Tell us your printer models and we will advise on spool dimensions.
Do you sell to private customers?
Filamenti.eu is built for businesses — print farms, workshops, schools and manufacturers. Private customers can buy 1 kg CROFIL spools at 3dprinteri.hr.
How is VAT handled?
Businesses in another EU country with a VAT ID valid in VIES are invoiced without VAT (reverse charge, Art. 196 of Directive 2006/112/EC). Croatian businesses are invoiced with 25 % VAT. Deliveries to Switzerland, Norway and the UK are exports.
What is the lead time?
Spools are produced to order. The production slot is confirmed in the quote; shipping within the EU then takes 2–5 working days.
Is there a minimum order?
One spool is enough to get a quote. The price per kg drops with volume, and pallet orders get the best rate.
