The Choice: Build It or Buy It Closer to Ready
Deciding on a single-screw extruder for 3D filament is less about speed and more about how much of the drive system you are willing to assemble. The four machines here split cleanly into two jobs: some are extruder bodies that leave the motor and temperature controller to you, while one is a motorized unit with adjustable speed and temperature. So the first question is not what material you want to push through the screw-it is whether you already have a motor and controller on your bench.
Quick Take
Here is the decision in one breath: the DIY unit and the New unit are both described without the motor or temperature controller, while the INTSUPERMAI unit lists a motor, speed range, and adjustable temperature. The 110V/220V unit sits in the middle with three heating coils and both voltage options in the title. Start by deciding whether you want to build around existing drive components or buy a unit that includes the motor side.

Decision Matrix
| Machine | Decision Clue | Watch Out |
|---|---|---|
| 110V/220V Extruder | Voltage flexibility is the main differentiator | Heating-side specs are the focus, not a drive package |
| 110V DIY Extruder | DIY kit with a one-year warranty and high-temp screw | Motor and controller are not included |
| INTSUPERMAI Single-Screw Extruder | Best if you want the motor handled | Needs auxiliary finishing equipment |
| Extruder New | Most detailed screw and barrel dimensions | Motor part is not included |
Product Notes
3D Filament Single Screw Extruder 110V/220V Plastic Extrusion Processing Machine
Start here if 110V/220V voltage flexibility matters to you, since both voltages are in the title. The listed specs include three heating coils, so you have the heating portion covered whether you pair it with a 110V or 220V line. As an extruder body, it makes the most sense when you already have the frame, motor, and controller on hand. The listed filament diameter is part of the specs, so verify it lines up with your intended filament size before purchase. The concrete constraint is that you are buying a heating-side package rather than a full drive system. Use it as the reference point when comparing the DIY kits and the high-priced motorized unit.
3D Filament Single Screw Extruder 110V Plastic Extrusion Processing Machine DIY
This is a DIY project with the drive components left out. The description says it does not include a motor or temperature controller, so you supply those two pieces yourself. What you do get is a 45# steel screw rated to 300°C, two 110V 200W heating coils, and a one-year manufacturer warranty in the listed specs. The default nozzle is 2.5mm; a 1.75mm nozzle is described as a separate purchase, so decide your filament diameter early. That makes it an appealing starting set for someone who already owns a motor and controller and wants to assemble a working extruder. The limitation is equally direct: without those two components, this kit cannot run.
110V Filament Single-Screw Extruder Plastic Extrusion Processing Machine
This is the unit to choose when you want the motor included rather than sourced separately. The listed specs include a 90W motor, 0-25 r/min speed range, 300W heating power, and adjustable speed and temperature. Screw diameter is 15mm with an L/D ratio of 14:1, and the description names PEEK, PCL, ABS, PLA, PETG, TPU, and TPE as suitable materials. Maximum output capacity is listed at 0.1-0.5 kg/h, so this is a bench-scale extruder. It still requires auxiliary equipment such as molds, cooling, hauling, winding, or cutting to finish products, and the stated manufacturer warranty is six months. If you can build the line around it, the integrated drive package is the reason to look here.

This listing gives you the most mechanical detail to work with before you buy. The specs spell out a 20mm screw diameter, 330mm screw length, 30mm screw sleeve outer diameter, 28mm inlet diameter, 15mm screw output shaft diameter, and three 200W heating coils. That detail makes it easier to match the extruder body to a motor you already have. The description states that the motor part is not included, so this is another build-around-it unit. The default nozzle aperture is 2.5mm, which is the filament diameter to plan around unless you swap nozzles in your own setup. The limitation is the missing drive package: you need to provide the motor and temperature controller before it can function. If maximum spec transparency matters to you, this is the listing to read.
Final Recommendation by Use Case
- For an integrated bench unit: consider the 110V Filament Single-Screw Extruder at USD 1,567.50 if you want a motor and speed/temperature adjustment in the listed specs and can add auxiliary finishing equipment.
- For the lowest listed price: the 3D Filament Single Screw Extruder 110V Plastic Extrusion Processing Machine DIY at USD 132.99 is the pick when you already have a motor and temperature controller.
- For detailed mechanical specs before building: the 3D Filament Single Screw Extruder Plastic Extrusion Processing Machine New at USD 161.39 gives you the most dimensions to mate with your own motor.
- For voltage flexibility: the 3D Filament Single Screw Extruder 110V/220V Plastic Extrusion Processing Machine at USD 149.99 is the reference if both 110V and 220V are on your bench.
