What comes out per kilo in
Purge, start-up and off-tolerance losses. Confirm for your material with 3devo.
%
Per kilo, if grinding, sieving or drying your own waste costs you anything. Zero if it does not.

How you would run it

Sets annual capacity and running cost
Set to 1 kg/h as a planning figure, and 0.5 kg/h for the high-temperature materials. 3devo's published tested reference is 1.5 kg/h on PLA, so this default is deliberately below it.
kg/h
Designed for 24/7. Two shifts is a common starting point.
h
250 is a standard single-site working year.
d
Time lost to material changes, cleaning and calibration.

One FMX10 holds a full 3 kg spool run unattended.

What running it costs you

Subtracted from the saving
400 W average, from 3devo. Not yet in the published specification, so confirm it for your voltage before you rely on it.
kW
Per kilowatt-hour, as billed.

3 kg is the machine's maximum.

Zero if you reuse them.

Carbon footprint

Only used when you recycle your own waste
Cradle-to-gate CO₂ for making a kilo of this polymer new. Indicative — published figures for the same polymer vary widely.
kg
Per kWh. 0.25 is the EU average 3devo uses; a renewable contract is far lower and a coal-heavy grid far higher.
kg
Per kilo of recycled feed. 0.85 kWh/kg is 3devo's measured figure — pre-shredding 0.10, granulating 0.08, drying 0.667.
kWh
Per kilo diverted. Burning polymer releases roughly 2 kg CO₂/kg, but 3devo leaves this out of its headline figures, so it starts at zero.

Your overview:

How it works

An ROI figure is worth only as much as its assumptions, so all of them are here. Machine capabilities are quoted from 3devo's published specification, and filament prices are European market medians stated with the number of stores and listings behind each.

The feedstock prices are different, and you should treat them differently. They are indicative placeholders, not quotations. What a kilo of pellets, regrind or powder actually costs depends on the supplier, the grade, the region and how much you order — published prices for the same polymer span more than tenfold, from tonne-scale resin to small compounded bags. Nobody can give you a single honest number for that, so we have not pretended to. It is also the field that moves the result more than anything else on this page, which makes replacing it with your own quote the first thing worth doing — and the thing most worth asking us about.

Assumption

Throughput
Published tested reference is 1.5 kg/h with PLA and varies with material density and settings. The calculator defaults to 1 kg/h — deliberately below it — and 0.5 kg/h for PEEK and PEI.

Maximum spool
Locking spool holder takes spools up to 3 kg and Ø300 mm.

Feedstock accepted

Bought filament price
European median price for a standard single spool, measured across every store tracked and stated per material with its store and listing count. Non-euro markets converted at ECB reference rates. Where no index covers a material (PP, PC/ABS, PEEK, PEI) a named product price is used instead.

Market
Feedstock price
Indicative placeholder. Pellet, regrind and powder prices vary enormously by supplier, grade, region and order quantity — there is no single right number, and published figures for the same polymer span more than tenfold. Treat these as a starting point only and replace them with your own quote.

Recycled share
Material from your own waste stream is treated as costing nothing to buy, because you already own it. Any cost to grind, sieve or dry it is a separate field under the detailed settings, and defaults to zero.
0% (your choice)

Carbon method
Recycled material displacing virgin polymer, less all electricity the line uses. The virgin share is treated as carbon-neutral against imported filament, and the conversion, spooling and freight of imported filament are excluded — so the real saving is higher than shown.
See below
Spec
Grid carbon factor
EU average used throughout 3devo's carbon reporting. Replace it with your own supply contract's factor.
0.25 kg CO₂/kWh
Spec
Virgin polymer carbon factor
Indicative. Cradle-to-gate CO₂ to make a kilo of new polymer. PP (1.91) and TPU (5.70, as polyurethane) are peer-reviewed European figures; PETG is scaled from PET at 2.94. The rest are estimates — published figures for a single polymer family span 3.5 to 11.7 kg CO₂/kg, so this is the field to replace if carbon matters to your case.

Avoided incineration
Burning polymer releases roughly 2 kg CO₂ per kilo. 3devo excludes this from its headline figures, so it starts at zero here and is yours to add.

What the model does not count

These are real reasons customers move production in-house, and none of them is in the arithmetic above — so treat the payback figure as the floor of the case rather than the whole of it.

Not Counted
Why It Matters
Waste you already pay to remove
MJF and SLS powder, regrind and failed prints are a disposal cost today. Feeding them into the machine replaces a bought kilo and deletes a disposal charge, but the numbers are specific to your waste stream and your contractor.
Supply security
A material on allocation, discontinued, or on a twelve-week lead time has a cost that only shows up when a line stops.
Filament nobody sells you
Custom blends, filled compounds, colour matching and validation grades have no market price to compare against, because you cannot buy them.
Freight, duty and stockholding
Extruding on site removes inbound freight on finished filament and the working capital tied up in spools on a shelf.
Freight and end-of-life emissions
The CO₂ figure above counts only the virgin polymer you avoid making, less the electricity you use. The freight of imported filament, and the emissions from incinerating or landfilling the waste you divert instead, sit on top of it — 3devo's methodology leaves both out to stay conservative, so the real saving is larger than shown.

Disclaimer

This model is a planning tool, not a quotation. 3devo makes no representation that any particular saving or payback period is achievable in your operation. Machine capabilities are quoted from the Filament Maker X10 specification; the published throughput reference is 1.5 kg/h with PLA as tested by 3devo, and this model deliberately defaults below it. Feedstock prices shown are indicative placeholders only and will differ from what you are quoted; pellet, regrind and powder pricing varies widely by supplier, grade, region and order quantity. Filament prices are European market medians collected on September 2026, stated per material with the number of stores and listings behind each, with non-euro markets converted at ECB reference rates. Recycled material from your own waste is counted at zero purchase cost. The currency selector changes the symbol only, it does not convert the figures.
