The Felfil Evo Complete Kit is the solution for who want to build their own extruder, step by step. Then, it is shortly to begin to extrude.
Buying this package you will get all the components of Felfil Evo, you just have to assemble them following the instruction manuals.
What material you can extrude
Felfil Evo Filament Extruder is supplied with a maximum temperature of 250 °C or 300 °C, chosen when you order to cover the common 3D printing polymers.
If you have a specific material in mind, the full list is on our materials page — and if it is not there, ask us: we test new blends regularly.
Every machine ships with a material sample of about 250g, enough for a first calibration run on the day it arrives.
It is suitable for experimental blends and composites, indeed this is where a desktop extruder earns its place. Small batches, one recipe at a time: our education kit, for example, includes recipes that mix coffee grounds with PLA.
PLA
The most common material, and the one to start with. It is also the material most often recycled from failed prints.
TPU
Possible at lower speed: soft materials need a slower screw RPM and steadier feed.
ABS
One of the easiest polymer to work with, can be extruder with very good tolerance. But it needs a ventilated room.
PETG
Excellent results, provided the material is properly dried. It is the polymer we use to send as sample.
Powerfull Gearmotor
The Felfil Evo gearmotor has been selected for its reliability and power quality. It allows to Felfil Evo to work in a excellent way with many materials

FAQ
Find the answers to the frequently asked questions here.
There are the most common question about Felfil Evo, directly asked by our customers.
What is the difference between Basic and Complete Kit?
The Felfil Evo Complete Kit includes all the component of the Felfil project, instead the Basic Kit includes only the mechanical parts. In this case you have to complete the extruder following our guides.
Do I need to dry the material before extruding?
Yes, almost all materials need to be dried before extrusion: moisture causes bubbles and diameter variation. A few hours in a filament dryer or a low oven is enough.
What materials can Felfil Evo extrude?
Felfil Evo works with the most common 3D printing polymers — PLA, ABS, PETG, TPU, HIPS — in pellet form or as shredded prints. It also handles experimental blends: our education kit includes recipes that mix coffee grounds with PLA. Some engineering polymers need higher temperatures than Evo reaches.
Can I use failed prints and plastic waste?
Yes, that is what it is built for. Failed prints need to be shredded into flakes first — that is what the Felfil Shredder+ does — and dried before extrusion. Recycled material behaves differently from virgin pellets: expect a short calibration on the first run.
What is the max size of the pieces that Felfil Evo can process?
Felfil Evo can work with a material size of about 6x5x5 mm also in irregular shape. You will obtain a better output if the material is homogeneous.
What filament diameters can it produce?
Both 1.75 mm and 2.85 mm — you change the nozzle, and both nozzles are included. Measured tolerance is ±0.07 mm, which is in line with entry-level commercial spools and more than enough for most prints
How much filament can I make in an hour?
Between 100 and 150 grams per hour, depending on material and settings. A standard 750 g spool takes roughly five to seven hours of unattended extrusion
Is the filament good enough for real printing?
The “Protection mode” appears when the motor power consumption is too high (more than 2A @12V).
Yes. A peer-reviewed study on recycled PETG produced with the Felfil system reports tensile test results according to ISO 527 (Dohan et al., Frattura ed Integrità Strutturale, vol. 70, 2024). Consistency depends on the material and on how well it is dried — recycled filament is not identical to industrial spools, and we prefer to say so
Kit or assembled, which should I choose?
Assembled if you want to extrude the day it arrives. Complete Kit if you want to build it yourself and understand the machine: every part is included. Basic Kit if you already have 3D printer electronics and want only the parts that are hard to make — screw, melting chamber, nozzle, gearmotor and support.
Do I need the Shredder and the Spooler too?
Not to start. Evo alone extrudes from pellets. You need the Shredder+ if you want to recycle your own prints, and the Spooler+ if you want the filament wound evenly onto a spool without doing it by hand. Most customers who recycle end up with all three, which is why they are also sold as a bundle.
Is it safe to use at home or in a classroom?
Yes, with the same care you use for a 3D printer: the melting chamber runs hot and the area should be ventilated. It runs on universal 110-220 V mains, so it works anywhere without an adapter.
Can I use it for research and material development?
Yes — universities and R&D labs use Evo to test polymer blends in small batches, where buying industrial quantities of filament makes no sense. Every machine ships with a material sample of about 400 g, enough for a first calibration run.
What support and warranty do I get?
We offer free support via email and WhatsApp, and we usually respond within 24 hours.
The warranty period depends on the country of purchase. We generally provide a European warranty (2 years for private customers and 1 year for B2B customers). Outside Europe, the warranty is 1 year for all customers.
