{"product_id":"elegoo-neptune-4-max-fdm-3d-printer","title":"ELEGOO Neptune 4 Max FDM 3D Printer","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe ELEGOO Neptune 4 Max is a large-format FDM printer built for users who need both scale and speed in a single machine. With a 420 × 420 × 480 mm build volume, it opens up full-scale architectural models, large functional parts, and multi-object batch runs that smaller desktop printers simply can't accommodate. Pre-installed Klipper firmware on an ARM 64-bit 1.5 GHz quad-core processor delivers a standard print speed of 250 mm\/s with a maximum of 500 mm\/s and an acceleration of 8,000 mm\/s², with input shaping and pressure advance active for clean output at velocity.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAcceleration sensors on both the X and Y axes enable automatic calibration and real-time vibration compensation without manual tuning. The direct dual-gear extruder with a 5.2:1 gear ratio provides strong, consistent extrusion grip across the full material range, and the high-temp nozzle kit handles temperatures up to 300 °C via a 60-watt heating element with a brass heating block. A titanium alloy heatbreak minimises clogging risk, and automatic PID calibration of nozzle parameters maintains stable, precise temperature control throughout extended print runs.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eFive fans handle cooling at up to 9,600 rpm: two 4015 ball bearing fans, one 3010 ball bearing fan, and two 6025 ball bearing fans deliver comprehensive heat dissipation across the full build area. Robust POM V guide wheels, a double Y-axis profile, and dual rows of 3+3V wheels on the Y-axis provide the structural stability needed for accurate large-format output. Connectivity via LAN, USB, and Wi-Fi with GCode support makes the Neptune 4 Max suited to both network-integrated studio workflows and standalone operation.\u003c\/p\u003e","brand":"Astra Store ","offers":[{"title":"Default Title","offer_id":53623094116536,"sku":null,"price":39999.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/3035\/0008\/files\/1.webp?v=1782379616","url":"https:\/\/astrastore.art\/products\/elegoo-neptune-4-max-fdm-3d-printer","provider":"Astra Store ","version":"1.0","type":"link"}
