A 10-pack case of Pro PCTG Midnight Black arrives with each spool vacuum-sealed and ready.
No individual boxes. No refill spool assembly.

Ten Spools in One Box. Nothing Left to Throw Away.
FarmFuel is a closed-loop filament system built for print farms running 20 or more printers.
You vacuum-sealed Pro PCTG in Midnight Black, with no individual packaging, and a prepaid label to send the empties back.

Ten spools ordered means ten boxes to open, flatten, and stack somewhere.
Then a shipping carton, then a recycling run, and a dumpster bill — or both.
If you’re using refill coils, add the time spent reassembling spools and the filament coil lost every time a refill gets rushed and fails.
None of this shows up on a P&L, but it costs real money, and it happens every single week at scale.

No individual boxes. No refill spool assembly.
Open the case and start printing.

Pull a spool from the case. Load it. Keep printing.
Spool changes for the entire case take less than 2.5 minutes.
No refill coils.
No cardboard.
No extra steps.

When the spools are empty:
We handle the rest!
Simple. Repeatable. Scalable.
The packaging problem becomes obvious once it’s put on paper.
The CEO of 3D-Fuel ran these numbers after speaking with print farm operators.
Here’s what he found.
A 3D printer farm running 100 printers, each consuming 1kg every two days, running 6 days per week.
That’s:
With FarmFuel:
Dumpster rental for cardboard and plastic can range from $80–$300 per month, depending on location and service frequency.
Recycling runs require staff time and vehicle time. Neither appears on your filament invoice.
Refill coils fail when rushed.
One tangled or improperly loaded coil can ruin an entire spool.
At $20–$25 per spool, one failed spool per week equals:
$1,000–$1,300 in wasted filament annually.
FarmFuel uses AMS-compatible plastic spools, so no coil handling and no failure point.
“We didn't build FarmFuel to sell more filament. We built it because we kept seeing the same problem and believed there was a simpler way to solve it.”

FarmFuel isn’t asking you to change your filament; we’re offering a solution for all the packaging that comes with it. FarmFuel eliminates individual boxes and provides a closed-loop return system for empty spools.
Pro PCTG Midnight Black, 1.75mm, 1kg spools. The same engineering-grade Pro PCTG that is sold individually through 3dfuel.com, but now delivered without individual packaging.
If you’re already printing individual spools of Pro PCTG, no changes are necessary. This is the same great Pro PCTG, just in different packaging. If you’re new to Pro PCTG, we have already developed filament profiles for the most popular desktop 3D printers found in print farms. Pro PCTG prints similarly to PETG with slightly higher hotend temperatures (250–280°C) and a textured PEI bed at 80°C. No enclosure required.
Place everything back into the case, seal it, apply the prepaid label, and add it to your outbound shipments. 3D-Fuel handles the rest. The only packaging that will be discarded is the vacuum seal bags.
Launch inventory is limited to Pro PCTG Midnight Black, but additional colors and materials are planned. Early operators will have input into future expansions.
Contact 3D-Fuel directly at sales@3dfuel.com. Every case is vacuum-sealed and checked before shipping. If something arrives wrong, we’ll make it right.
