You must match the machine to your materials, prepare and often tune the process, and account for cooling, pulling, diameter measurement, and winding. No controlled, like-for-like tests establish a best performer among the Filabot EX3, Felfil, Damao Tech, FIXstruder, and DIY options covered here, so the right choice depends on your feedstock and willingness to manage the workflow.
What a filament extruder does—and what it does not guarantee
A filament extruder heats plastic feedstock and forms it into a continuous strand. Depending on the machine, that feedstock may be pellets, regrind, or clean, sorted recycled plastic. A machine’s broad description is not proof that it accepts every polymer, mixed scraps, or unprepared failed prints. Confirm support and preparation requirements for the exact model before buying.
Making filament is a workflow, not simply a heated barrel. Feedstock preparation, cooling, pull speed, diameter measurement, and winding can all affect the result. Filabot’s EX3 system is presented as a sequence from raw material to spool, while a published sensor study illustrates that diameter sensing is a distinct engineering problem; neither establishes consistent printer-ready output from a particular commercial machine.

| Filabot EX3 / EX3 System | Filabot describes the EX3 as a compact extruder for pellets, regrind, and recycled plastic. The system page presents a workflow with separate extrusion, airpath, winding, and measurement components. | Which components are included in the configuration you are considering, supported polymers, preparation needs, and current total cost. These are manufacturer descriptions, not independent performance findings. Filabot; EX3 System. |
| Felfil | The manufacturer describes a desktop recycler/extruder for waste plastic, failed prints, and pellets, for home or lab use. Independent coverage describes a modular setup and notes hands-on calibration and material preparation as practical considerations. | Exact polymer compatibility, preparation, included modules, and the calibration effort for your intended feedstock.

Choose by feedstock and preparation workload
Start with the plastic you can reliably supply, not with a machine’s broad recycling label. If you expect to use pellets, check whether the model names the polymers you intend to extrude. If you plan to reuse prints or supports, determine whether they must be sorted by polymer, cleaned, shredded into regrind, dried, or blended, and whether the manufacturer explicitly supports that material.
- Mostly pellets: Compare the supported polymers and the complete workflow required to turn pellets into a measured, wound strand.
- Clean, sorted scrap: Confirm how the machine handles that specific material and what size or condition it must be in before feeding.
- Mixed or unidentified waste: Do not assume compatibility. The product descriptions do not establish that arbitrary mixed waste can be processed successfully.
Material preparation and hands-on calibration are practical considerations in desktop recycling, as noted in Tom’s Hardware’s overview. If you want the convenience of feeding unsorted failed prints and receiving consistent filament without supervision, the evidence here does not establish that any listed option will provide it.

Compare the complete workflow, not just the extruder
Check whether a quoted configuration includes only the extrusion unit or also the components for cooling or airpath management, pulling, spooling, and diameter measurement. A system may be modular, so a product family’s description does not mean every component is included in the unit or package you are pricing.
Diameter monitoring deserves separate scrutiny. The sensor paper reports a sensor designed, built, tested, and validated for recycling and winding machines. That is evidence that measurement is a real process concern, not a benchmark of any named product. Ask how the machine measures diameter, whether readings are displayed or used for feedback, and what adjustment is available when the strand varies.

How to judge the evidence and the effort
Manufacturer pages establish what their makers claim about intended feedstock and system design; they do not independently prove output quality. Editorial coverage offers practical context on preparation and calibration, but it is not a controlled comparison of the listed machines. The available sources do not establish which one produces the most consistent usable filament.
Before choosing a desktop or modular system, be realistic about the work beyond assembly:

What to verify before placing an order
- Supported materials: Get the exact polymers and feedstock forms the specific model accepts, plus any preparation requirements.
- Package contents: Confirm whether the price covers the extruder alone or includes airpath or cooling, a puller, a spooler, and measurement equipment.
- Diameter control: Ask how diameter is monitored and what controls or feedback help correct variation.
- Ownership costs: Check current machine price, shipping, required modules, spare parts, warranty, and support for your country. Comparable current totals were not established for these options.
- Independent output evidence: Look for tests using the same material and a clearly described method; do not treat vendor specifications or demonstrations as equivalent to a controlled comparison.
- Availability: Verify current stock, seller, and project status directly. The product descriptions alone do not establish availability in your region.
Which type of buyer is each option for?
- Consider Filabot EX3 if a defined, modular path from feedstock to spool suits you; verify exactly which system components and material support are included in your chosen configuration.
- Consider Felfil if a desktop recycling-oriented setup matches your plans and you accept preparation and calibration work.
- Investigate Damao Tech if its described feedstock options fit yours, but treat its listed specifications as vendor claims until independently verified.
- Investigate FIXstruder if its stated failed-print and support use case is relevant, while recognizing that comparable independent evidence was not established here.
- Choose DIY if building, sourcing, and tuning are part of the goal; verify the project’s current files, licensing, status, and parts before committing.
