- Compatible with Creality Ender 3, Anycubic Mega, and Prusa i3 series
- Requires manual E-step adjustment between 385 and 415
Who it fits
Good fit for
This kit suits owners of Creality Ender 3, Anycubic Mega, or Prusa i3 printers who want to upgrade from stock extruders. The dual drive design with a 3:1 ratio is ideal if you struggle with filament slipping or under-extrusion. It works well for users who are comfortable adjusting E-steps manually. If you need a direct drop-in replacement without configuration, this may not be the best fit. It is a practical choice for hobbyists looking to improve print reliability on these specific models.
Who should skip it
You should look elsewhere if you need an extruder for a printer not listed in the compatibility data. The product is designed as a remote drive unit, so it will not fit direct-drive setups without significant modification. If you prefer a plug-and-play experience with pre-calibrated E-steps, this kit requires you to set the values yourself. It is also not suitable if you need a single unit, as the listing specifies a two-pack configuration. Check your printer model carefully before purchasing.
Verdict: This is a spec-focused upgrade for specific 3D printer models that need better filament grip. It offers a solid mechanical solution for users willing to adjust their firmware settings.
Key specs for SIMAX3D extruder
Extruder Type: Dual Drive Extruder
This design uses two gears to grip the filament. It provides better traction than single-gear models. This helps prevent grinding or slipping during printing. You benefit from more reliable extrusion, especially with flexible materials. Compare this to standard direct drive units when shopping for upgrades.
Internal transmission ratio: 3:1
This ratio determines how much the motor turns the gear. A 3:1 ratio increases torque and precision. You get finer control over filament movement. This is useful for accurate layer adhesion. Check this spec against other geared extruders to ensure compatibility with your printer’s firmware settings.
Package include: Dual Drive Extruder *2Pcs
The kit contains two identical units. You can install one now and keep the other as a spare. This is practical for maintenance or upgrading multiple printers. Compare the quantity to single-unit listings. Having extras ensures you are prepared for future replacements without waiting for new shipments.
Color: Black
This is the standard finish for this component. It matches most printer frames and upgrade kits. This helps the part blend in visually with your machine. While cosmetic, it ensures a consistent look. Verify this color matches your printer’s aesthetic when selecting replacement parts for your setup.
Design and Build Analysis
The listing describes the SIMAX3D Dual Drive Extruder 2-Pack as a black upgrade component. It contains two units, each measuring 2.2 inches in height. The total package weight is 9.95 ounces. This compact size allows it to fit into standard printer frames without requiring major structural changes. The black finish matches common printer aesthetics, keeping the interior look uniform. You get two extruders in one box, which simplifies installation if you need to replace both units or keep a spare on hand.
The design relies on a 3:1 internal transmission ratio. This gearing increases torque, which helps the extruder grip filament more firmly. You do not need to adjust the hand twist screw too tightly. If you overtighten it, the filament may get stuck in the Bowden tube. Proper adjustment ensures smooth feeding without crushing the material. The unit is built for remote drive configurations. This layout is typical for printers that use a separate extruder mounted away from the hotend.
According to the listing, this model is compatible with Creality Ender 3, Anycubic Mega, and Prusa i3 series printers. You should verify your specific printer model before purchasing. The E-step value is recommended to be between 385 and 415. You must set this value in your printer firmware to match your specific setup. This step is crucial for accurate extrusion. The design prioritizes mechanical reliability over electronic features. You get a straightforward mechanical upgrade that enhances feeding precision.
Setup and Daily Use Guide
You install this SIMAX3D Dual Drive Extruder 2-Pack as a replacement for your printer’s stock unit. The listing notes the original version is for remote drive setups, so you must verify your printer’s configuration before mounting. It is compatible with Creality Ender 3, Anycubic Mega, and Prusa i3 series models. This compatibility list helps you confirm if your hardware matches the design.
Setup involves mechanical assembly and software calibration. You adjust the hand twist screw to load filament properly. The instructions warn against tightening it too much, as excessive pressure can cause filament to get stuck in the Bowden tube. This step requires careful handling to ensure smooth feeding.
The unit features a 3:1 internal transmission ratio. This mechanical advantage increases traction and accuracy. You will likely need to update your printer’s E-step settings. The recommended range is 385 to 415 steps per millimeter. You must set this value according to your specific 3D printer model. Correct calibration is essential for the dual gears to grip the filament effectively without slipping.
Daily use relies on this precise gearing. The dual drive system reduces the risk of grinding soft materials. You benefit from more consistent extrusion during long prints. The black finish matches standard printer components. The package includes two units, allowing you to keep a spare or upgrade multiple machines. You contact the brand for technical support if you encounter installation issues.
Before You Buy SIMAX3D Extruder
You need to verify your printer’s drive style before ordering. The listing states the original version is for remote drive setups. If your machine uses a direct drive, this part may not fit correctly. You must also check compatibility with your specific model, such as the Creality Ender 3 or Anycubic Mega. The package includes two units, so you have a spare if one fails. You will need to adjust your E-step settings, typically between 385 and 415, to match the 3:1 internal transmission ratio. Tighten the hand twist screw carefully to avoid filament jams. This upgrade suits users who want better traction for flexible filaments. It fits well alongside other extruder options in the 3D Printers & Making Tools category. You get a practical solution for extrusion issues without buying a whole new printer.
Check before you buy
- Confirm your printer uses a remote drive setup
- Verify compatibility with Ender 3 or Anycubic Mega
- Plan to adjust E-step settings to 385-415
- Ensure you have tools for proper screw tightening
