Quick take
Buying a single screw extruder for 3D filament is a trade-off between assembly effort, control options, and outlay. Some of these machines arrive as bare extruder bodies, others as kits that require additional components, and one is positioned as a more complete processing unit that expects downstream equipment. Your decision should start with how much you want to build a system from components versus buy a more complete processing unit. The four machines here cover that range, so the choice is less about which one is 'best' and more about which missing piece you are willing to supply.
What to consider
Most of the practical difference sits in assembly effort and how much you are expected to supply around the extruder itself. The lower-priced machines put more work on the user, while the higher-priced unit is a different class of outlay. Understanding that split is the key to choosing the right one.
Listed price comparison
The listed prices spread from USD 132.99 to USD 1,567.50. The three lower-priced machines sit within $27 of each other, while the INTSUPERMAI unit is more than a thousand dollars above them. The gap reflects a move from simple extruder bodies to a unit with more listed specifications.

Product notes
3D Filament Single Screw Extruder 110V MicroPlastic Extrusion Processing Machine
This compact single screw extruder is positioned for experimental research, small batch testing, and special 3D filament extrusion. It includes an aluminum alloy heat sink, dual-clamp screw mounting, and 200W ceramic heating coils. The default nozzle is 2.5mm; a 1.75mm nozzle would be a separate purchase. You can also choose a smooth shaft diameter of 12mm or 15mm. If you are looking for a small desktop-style processing unit with heating coil flexibility, this one pairs that utility with a compact footprint.
3D Filament Single Screw Extruder 110V Plastic Extrusion Processing Machine DIY
This is the lowest-priced option in the group. The motor and temperature controller are not included, so you are buying a build-it-yourself accessory kit. The screw is made of 45# steel and rated for high-temperature resistance up to 572°F / 300°C, and the kit includes two 110V ceramic heating coils at 200W each. A 1-year manufacturer warranty is part of the package. If you already have a motor and controller on hand, this kit gives you the core extruder components at the smallest outlay. Just plan for the assembly work and the extra parts you will need to drive the screw.
110V Filament Single-Screw Extruder Plastic Extrusion Processing Machine
This is the highest-priced machine in the set, and it is the only one with explicit temperature and speed adjustment. The 15mm screw is driven by a 90W motor with 300W heating power, and it supports PEEK, PCL, ABS, PLA, PETG, TPU, TPE, and other common 3D printing consumables. Maximum output is rated at 0.1-0.5 kg/h. Keep in mind that the machine needs auxiliary equipment such as moulds, cooling, hauling, winding, or cutting machines to complete products, and one of two styles will be shipped at random. The manufacturer warranty is 6 months. If you want an adjustable processing setup and can build out the supporting line, this is the one to budget for.
3D Filament Single Screw Extruder 110V/220V Plastic Extrusion Processing Machine
The main reason to choose this machine is the voltage flexibility: it explicitly supports both 110V and 220V, so it can fit workshops with different power setups. It is a single screw plastic extruder that heats, melts, kneads, and pressurizes solid raw materials into continuous profiles. The default nozzle is 2.5mm, and a 1.75mm nozzle is a separate purchase. If your workspace runs on 220V, this is the practical pick among the lower-priced options. Plan around the nozzle setup if you mostly use 1.75mm filament.
Final recommendation
Start with the 3D Filament Single Screw Extruder 110V Plastic Extrusion Processing Machine DIY if your goal is the lowest listed price in this group. Pick the 3D Filament Single Screw Extruder 110V/220V Plastic Extrusion Processing Machine when it fits your workspace. Choose the 3D Filament Single Screw Extruder 110V MicroPlastic Extrusion Processing Machine when its profile fits your work. And for the highest-priced model, the 110V Filament Single-Screw Extruder Plastic Extrusion Processing Machine is the one to budget for.
