Getting Started with DualPrint: A Beginner’s Setup GuideDualPrint—printing with two nozzles, two filaments, or two functional heads—lets hobbyists and professionals expand their 3D prints’ complexity, speed, and material versatility. This guide walks you through the concepts, hardware choices, software setup, calibration, troubleshooting, and beginner projects so you can go from unboxing to your first successful dual-print.
What is DualPrint and why use it?
DualPrint refers to any system that allows a single print job to use two separate extruders or print heads. Typical benefits:
- Multi-material printing (e.g., rigid + flexible or soluble supports).
- Multi-color prints without pausing to swap filament.
- Improved throughput by allowing one head to print while the other heats/cleans (on some designs).
- Specialized toolheads (e.g., paste extruder + filament extruder) for hybrid workflows.
Types of dual-extruder systems
- Dedicated dual-hotend (two nozzles on a shared carriage) — compact, common on consumer machines.
- Independent Dual Extruder (IDEX) — two independently moving carriages, enabling mirrored/duplicated prints and reduced toolpath collision.
- Multi-material upgrade modules (e.g., MMU-style) that feed multiple filaments into a single hotend — useful for many colors but different from true dual-hotend behavior.
- Toolchanger systems — advanced, often used in prosumer/industrial printers to swap heads.
Hardware checklist
Essential components and considerations:
- Printer compatibility: check frame size, carriage mounting, firmware support.
- Dual hotend or second extruder carriage (match voltage, thermistor types).
- Matching or appropriate nozzles (diameters can differ for purposes like supports).
- Filament drive systems: direct vs Bowden—choose based on your filaments.
- Electronics and firmware: enough stepper drivers and configured to support two extruders (or
