HTA3D printed parts kit for P3Steel Dual / Prusa i3 Steel – Dual extrusion

This set contains the printed parts specifically designed for the HTA3D P3Steel Dual. It includes the components required for the dual-extrusion mechanical configuration and auxiliary parts adapted to our P3Steel steel frame.

It is intended for building, repairing or updating an HTA3D P3Steel Dual and should not be confused with the single-extrusion printed-parts set.

Compatibility

The parts are designed for the HTA3D P3Steel Dual DIY kit and the P3Steel / Prusa i3 Steel frame.

Compatibility with other P3Steel, Prusa i3 Steel or third-party dual-extrusion conversions may be partial. The frame, X carriage, extrusion system, hotend, endstops and electronics must be checked before using the set on another machine.

This set is also not directly compatible with the later HTA3D 3DSteel or 3DSteel V2 designs, which use different mechanical components.

Set contents

Dual extrusion for 1.75 mm filament

• 2 symmetrical extruder bodies.
• 2 symmetrical extruder idler levers.
• Hotend mount.
• 4020 layer-cooling fan mount.

These parts correspond to the HTA3D dual configuration. Compatibility with a particular hotend or extruder must be checked before assembly. The HTA3D dual extruder for P3Steel can be used as a reference.

X-axis parts

• X-axis motor mount.
• X-axis idler mount prepared for an F624ZZ bearing.
• X-axis tensioner.
• X-axis carriage.
• X-axis endstop mount.

Y-axis parts

• Belt mount.
• Holders for LM8UU linear bearings.
• Motor spacers.
• Heated-bed levelling corners.
• Y-axis endstop mount.

Z-axis parts

• Upper Z-axis parts prepared for MR105ZZ bearings.
• Z-axis endstop mount.

Electronics and finishing parts

• Enclosure for RAMPS 1.4 electronics.
• Printed mount for an additional MOSFET module.
• LCD enclosure.
• Power-supply cover.

The MOSFET holder is only a mechanical printed part. The MOSFET module is not included, and compatibility depends on the dimensions and mounting points of the selected board.

Parts required to complete the P3Steel Dual

This product contains only the printed parts. They can be combined with the P3Steel motion kit, P3Steel rod kit and HTA3D P3Steel Dual fastener kit.

The frame, fasteners, bearings, rods, motors, belts, hotends, fans, electronics, MOSFET module, power supply and heated bed are not included unless explicitly stated in a product option.

Dual-extrusion considerations

• Check the hotend model and mounting pattern before assembly.
• Align both nozzles in height to prevent one from interfering with the other's print.
• Ensure that the X carriage moves freely with the additional weight.
• Arrange the wiring so that it does not restrict X-axis travel.
• Configure the electronics and firmware correctly for dual extrusion.
• Do not overtighten screws installed into printed parts.

The inclusion of dual-extrusion parts does not guarantee compatibility with every combination of extruders and hotends. The final assembly must be checked as a complete system.
