If you're setting up a small plastics lab or want to turn resin pellets into 3D filament, the first machine on your bench is usually a single-screw extruder. The difficulty is that the category spans DIY kits and a serious bench instrument, with listed prices from $132.99 to $1,567.50. The practical tension is that the cheaper options look similar at a glance, but they differ in heating-coil count, screw dimensions, and whether the drive is already included.
Quick take
The three lower-priced machines all sit below $170 and are best treated as extrusion heads or kits. One of the sub-$170 listings states directly that the drive and temperature controller are not included, and the dual-voltage model is framed as the core piece of a larger processing line. The INTSUPERMAI unit is the outlier, with a much higher listed price and a more complete specification.

Product notes
3D Filament Single Screw Extruder 110V 3 Heating Coil Plastic Extrusion Machine
The 20mm screw runs 330mm long and the listed material range covers PE, PP, PS, PVC, POM, PA, PC, ABS, and PET. That makes it a flexible experimental unit for small-batch filament work. The main catch is that the drive is not in the box: the listed setup expects a 50 RPM, 200W drive with 15Nm torque. You will also need to preheat the barrel to the material melting point before you start, so plan for a separate temperature controller and drive setup.
3D Filament Single Screw Extruder 110V Plastic Extrusion Processing Machine DIY
This DIY extruder is built around a single-shaft steel screw and a default 2.5mm nozzle. It is described as ready for assembly and includes a one-year manufacturer warranty. The trade-off is that the drive and temperature controller are not included, and the 1.75mm nozzle is sold separately. If you already have a drive system and controller, this is a straightforward way to keep the initial spend down while still working with a steel screw rated up to 300°C.
3D Filament Single Screw Extruder 110V/220V Plastic Extrusion Processing Machine
This one answers the voltage question before you buy: the title flags both 110V and 220V. It also lists universal compatibility, so it slots into the same DIY extrusion workflow as the other lower-priced machines. The description focuses on the extruder's role in heating, melting, kneading, and pressurizing plastic raw materials, which is a useful reminder that the machine is the center of a larger processing line. The limitation is practical: with a dual-voltage listing, you need to choose the configuration that matches your local power supply.
110V Filament Single-Screw Extruder Plastic Extrusion Processing Machine
INTSUPERMAI's machine is the only one here that includes its own drive: a 90W motor with speed control from 0 to 25 r/min. The 15mm screw, 300W heating power, and maximum output of 0.1 to 0.5kg/h make it a more complete bench instrument, and the material list includes PEEK, PCL, ABS, PLA, PETG, TPU, and TPE. The description says auxiliary equipment such as moulds, cooling, hauling, winding, or cutting machines is still needed to finish products, so the overall line is not turnkey. That integration work is the main limitation, and the listed price reflects the jump in capability.
Final recommendation by use case
- For a DIY lab experiment: Choose the 3D Filament Single Screw Extruder 110V Plastic Extrusion Processing Machine DIY. It has the lowest listed price in this group, and the listing is explicit that the drive and temperature controller are separate.
- For a 110V-only setup: The 3D Filament Single Screw Extruder 110V 3 Heating Coil Plastic Extrusion Machine is the three-coil match for a 110V workbench.
- For flexible voltage: The 3D Filament Single Screw Extruder 110V/220V Plastic Extrusion Processing Machine is the one to pair with either power source.
- For a more complete bench unit: The 110V Filament Single-Screw Extruder Plastic Extrusion Processing Machine from INTSUPERMAI is the step-up choice in this group.
