The Elegoo Neptune 4 Plus is a large-format, high-performance FDM 3D printer engineered for projects that require both scale and accuracy. Its generous build volume of 320 × 320 × 385 mm removes the need to split medium-to-large models, enabling single-run prints of prototypes, functional parts, display models and large decorative pieces.
Precision & motion
With quoted dimensional precision of ±0.1 mm, a 0.4 mm nozzle and a maximum acceleration of 12,000 mm/s², the Neptune 4 Plus balances fine detail with fast motion. Print speeds span from conservative 30 mm/s up to 500 mm/s peak, while a practical working sweet spot near 250 mm/s delivers an excellent compromise between surface finish and throughput for everyday use.
Thermal capability & materials
A maximum nozzle temperature of 300°C and a heated print bed reaching 110°C expand the material palette beyond basic PLA. The system can accommodate standard thermoplastics and many engineering filaments that require higher extrusion temperatures; the heated bed improves adhesion for materials that need it. Because exact filament support can vary with slicing settings and environmental conditions, users should test new materials and adjust print parameters accordingly.
Workflows & connectivity
Neptune 4 Plus integrates with commonly used slicers (e.g., Cura) and accepts STL/OBJ input to produce standard G-code output. Data transfer and control are simple via USB or network (LAN), allowing local job submission and monitoring without complex setups. The printer’s intuitive workflow helps both newcomers and experienced users get prints started quickly.
Mechanical stability & usability
At 578 × 533 × 640 mm and roughly 14.4 kg, the unit is stable enough to minimise vibration while still fitting on most workbenches. A solid frame and well-dimensioned motion components contribute to repeatable results and reliable layer alignment—especially important for long or tall prints. Quick-change nozzle design speeds maintenance and nozzle swaps, while the rapid-heating bed (to 110°C) reduces idle time between prints.
Ideal use cases
The Neptune 4 Plus is particularly suited for makers who build large-scale models, engineers prototyping assemblies, educators demonstrating real-world 3D printing, and small businesses that need both high print capacity and detailed reproducibility. Its combination of speed, temperature range and print area makes it a flexible tool for concept iterations, functional testing and finished parts.
What’s included / practical notes
The printer ships as a compact, largely pre-assembled unit. Users should ensure workspace ventilation for certain engineering filaments, confirm filament compatibility, and follow standard bed-levelling and slicer setup procedures to achieve the best results. Regular maintenance—clean nozzle, check belts, and keep firmware/slicer profiles updated—will maximise print quality and longevity.
