What Is a 3D Printer Filament Maker?
A 3D printer filament maker — also called a filament extruder — is a machine that melts raw plastic pellets and forces them through a precision die to produce a continuous strand of filament in a specific diameter (typically 1.75mm or 2.85mm). The filament is then cooled, measured, and wound onto a spool for use in your FDM printer.
What is Filament Extruder?
Filament Extruder A machine that melts raw thermoplastic pellets using a heated barrel and screw mechanism, then forces the molten material through a precision die nozzle to produce continuous 3D printer filament at a controlled diameter. Most desktop units produce 1.75mm or 2.85mm filament at rates of 100–200g per hour.
3D Printer Filament Types and Uses — Complete Guide 2025
Understand all filament types before deciding which material to extrude — covers PLA, PETG, ABS, TPU, Nylon, and specialty materials.
How Does a Filament Extruder Work?
The process has four main stages:
- Feeding: Plastic pellets drop into a hopper and feed into a rotating screw inside a heated barrel.
- Melting: The barrel heats the pellets to the material's melt temperature (e.g., 180–220°C for PLA).
- Extrusion: The molten plastic is forced through a precision die — the die diameter determines your filament diameter.
- Cooling & Winding: The extruded strand cools in air (or a water bath on pro models) and is wound onto a spool, sometimes with an automatic winder.
What Materials Can You Use in a Filament Maker?
Most desktop filament extruders support these pellet types:
PLA
Easiest — low temp, forgiving, widely available pellets
PETG
Good mid-range option — slightly higher temps, moisture-sensitive pellets
See best PETG filament →ABS
Requires higher temps and ventilation — warping during extrusion is common
Nylon
Challenging — hygroscopic pellets must be pre-dried; high-temp extrusion required
See best Nylon filament →CF-blends
Requires hardened steel die — abrasive on standard brass components
Best Hardened Steel Nozzle 2025
Carbon fiber and abrasive filament blends wear out brass nozzles fast — a hardened steel nozzle is essential for CF-blended extrusion.

Is Making Your Own Filament Worth It?
This is the most important question — and the honest answer is: for most hobbyists, no. Here's why the math often doesn't add up.
How Much Does a Filament Maker Cost to Run?
| Cost Factor | DIY Filament | Polymaker Retail |
|---|---|---|
| Raw material cost | $2–5/kg pellets | $15–25/kg spool |
| Machine amortized (over 2 years) | +$12–20/kg | $0 |
| Your time (30–60 min setup/batch) | +$5–15/kg | $0 |
| Failed batches / waste | +$1–3/kg | $0 |
| Diameter consistency | ±0.05–0.10mm | ±0.02mm |
| Effective total cost | ~$20–43/kg | $15–25/kg |
The Break-Even Reality
Once you account for machine cost, your time, and failed batches, DIY filament typically only becomes cost-effective if you're printing 10kg+ per month consistently. Most hobbyists print 1–3kg/month — in that range, buying quality filament is almost always cheaper.
Best Budget PLA Filament Under $15 (2025)
Premium PLA filament under $15/kg — often cheaper than the true cost of DIY extrusion once you factor in machine and time.
When DIY filament makes sense:
- You want to experiment with custom material blends (color mixing, additive pellets)
- You're recycling failed prints and plastic waste at high volume
- You need exotic materials not sold as retail filament
- You're in a research or educational lab setting

How Do You Choose the Right Filament Maker?
If you've decided a filament extruder is right for you, here are the key factors to evaluate:
What Diameter Filament Does Your Printer Use?
Almost all modern FDM printers use 1.75mm filament. Some older or professional machines use 2.85mm (sometimes called 3mm). Confirm your printer's specification before purchasing an extruder — most quality machines support both diameters with die swaps, but verify before buying.

What Throughput Speed Do You Need?
Desktop extruders produce 100–200g of filament per hour. At 150g/hr, producing a single 1kg spool takes roughly 6–7 hours of unattended run time. For most hobbyists this is perfectly acceptable — but if you need multiple spools per week, look at higher-throughput machines like the 3Devo Filament Maker ONE.
Budget
Under $400: Filastruder or Noztek Pro. $400–600: Felfil Evo or Recreator. $3,000+: 3Devo ONE.
Recycling Focus
Recreator 3D is purpose-built for recycled plastic input. Requires a companion shredder.
Material Range
All handle PLA. For Nylon or high-temp materials, ensure the machine reaches 250°C+.
Automation
Manual winding: Filastruder, Noztek. Auto-winding: 3Devo ONE. Semi-auto: Felfil Evo.
Best Filament Dryer 2025
Whether you're extruding or buying filament, a good filament dryer is essential — especially for hygroscopic materials like Nylon and PETG.
Frequently Asked Questions About 3D Printer Filament Makers
How much does it cost to make your own 3D printer filament?
Raw plastic pellets for PLA cost roughly $2–5/kg, compared to $15–25/kg for retail filament spools. However, factor in the $300–500 machine cost, electricity, your time, and failed batches. For most hobbyists printing less than 5kg/month, buying quality filament like Polymaker remains cheaper overall. High-volume users (10kg+ monthly) may break even after 6–12 months.
What plastic pellets can you use in a filament maker?
Most desktop filament extruders support PLA, PETG, ABS, TPU, and Nylon pellets. PLA is the easiest to extrude due to its low melting temperature and forgiveness. Nylon and ABS require higher temperatures and a more controlled environment. TPU needs a slower extrusion speed. Exotic pellets like PC or carbon-fiber reinforced materials require professional-grade machines like the 3Devo Filament Maker ONE.
Can I make 1.75mm filament at home?
Yes — most consumer filament extruders including the Filastruder, Felfil Evo, and Noztek Pro support both 1.75mm and 2.85mm nozzle diameters, switched by swapping the die. Achieving consistent diameter within ±0.05mm tolerance (the industry standard) requires careful temperature control and a constant feed rate. Cheaper machines may produce filament that clogs your printer if diameter varies too much.
Is recycling failed 3D prints into new filament possible?
Yes, but it requires two machines: a plastic shredder (to grind failed prints into pellet-sized pieces) and a filament extruder. The Recreator 3D is specifically designed for this use case. Be aware that each recycling cycle slightly degrades the plastic, affecting print quality over time. Mixed-material recycling (PLA + PETG together) produces unusable filament — sort your waste by material type.
Are DIY filaments as good as commercial filaments like Polymaker?
Honestly, no — not for most users. Commercial filaments like Polymaker undergo industrial extrusion with precise diameter control (±0.02mm), consistent material blending, and quality testing. Home extruders typically produce filament with more variance (±0.05–0.10mm), which can cause under/over-extrusion and clogs. DIY filament makes sense for custom material experiments or recycling, not for replacing quality retail filament for everyday printing.
Our Verdict: Should You Buy a 3D Printer Filament Maker?
If you print at high volume, want to experiment with custom materials, or are passionate about recycling your plastic waste — a filament extruder is a worthwhile investment. Start with the Filastruder Kit at ~$300 for the best balance of cost, community support, and proven reliability.
For everyone else — especially makers printing under 5kg per month — buying quality retail filament from Polymaker delivers better consistency at lower effective cost, with none of the setup headache. The Polymaker PolyTerra and PolyLite lines are produced to ±0.02mm diameter tolerance that no desktop extruder can match.
