IDEX420

The IDEX420 is an FDM 3D printer from eMotionTech with a 420 x 320 x 400 mm build volume.

Specifications

The eMotionTech Strateo3D IDEX420 is a high-end industrial FDM 3D printer manufactured by the French company eMotionTech. It is engineered for intensive professional use, rapid prototyping, and batch production of end-use parts using advanced engineering polymers. The cornerstone feature of this machine is its Independent Dual Extrusion (IDEX) setup, integrated into a fully enclosed, thermally controlled environment.

• Build volume: Large industrial capacity of 420 × 320 × 400 mm when printing with a single nozzle or in dual-material/dual-color mode. This volume allows for the creation of substantial functional components without cutting CAD files into segments.

Calibration

Calibrating an IDEX system like the Strateo3D IDEX420 requires matching physical settings with software parameters to align the independent toolheads.

• Glass Bed and Wipe Assembly Cleaning: Clean the borosilicate glass plate with 99% IPA before starting. Ensure the silicone nozzle wipers in the parking zones are free from plastic buildup.
• Expected result: Grease-free glass that ensures proper first-layer adhesion and clean nozzle tips that prevent calibration errors.

Common defects

• Hardware defects and mechanical weaknesses
• Symptom: Small X-axis offset drifts during long, continuous print jobs (over 24 hours).
• Cause: Overheating of the X-axis stepper motors caused by high ambient temperatures inside the 60°C heated chamber.
• Solution: Verify that the motor cooling vents are clear, or install passive heatsinks on the X-axis stepper motors.
• Symptom: Frequent clogging of the secondary hotend when feeding PVA support material.

What it is used for

Best use-cases:

• Functional Engineering Assemblies: Well-suited for fabricating housings, covers, and structural parts from PC-ABS, Nylon-CF, and ASA.
• Complex Overhangs with Soluble Support: Ideal for printing complex internal geometries, undercuts, and hollow channels using PVA or BVOH support materials.
