{"product_id":"mingda-ad-f4-3d-printer","title":"Mingda AD-F4 3D Printer","description":"\u003cp\u003eThe MINGDA AD-F4 isn't a general-purpose 3D printer — it's a dedicated production tool for sign shops and ad agencies that build LED channel letters and light boxes. Its 1200 × 800 × 100 mm bed is sized to print full letter sets and light-box faces in a single flat pass, and the IMS four-color automatic feeding system changes filament colors mid-print with zero manual swaps, so multi-color logos and lettering come off the bed ready to wire and mount. Speed is the other half of the pitch: running on Klipper, the AD-F4 travels at up to 300 mm\/s and prints layers as fine as 0.2 mm across a tempered-glass build plate — Mingda benchmarks an 800 × 765 × 80 mm light box at 8 hours, versus roughly 40 hours on a typical letter printer running the same job. Gravity-sensing auto leveling, filament-break detection, and power-loss resume keep long production runs on track, and Mingda's own AdWordCraft and MINGDA Slicer software handle vector import, font generation, and 2D-to-3D conversion, so sign designers can go from artwork straight to print without a separate CAD step.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003cbr\u003e• 1200 × 800 × 100 mm build volume — purpose-built for channel letters and light boxes\u003cbr\u003e• IMS 4-color automatic feeding system (4-in-1-out hotend) — in-print color changes, no manual filament swaps\u003cbr\u003e• Up to 300 mm\/s travel speed, 0.2–0.42 mm layer height, interchangeable 0.4\/0.6\/0.8mm nozzles\u003cbr\u003e• Klipper firmware, 7″ touchscreen, gravity-sensing auto leveling on a tempered-glass bed\u003cbr\u003e• Filament-break detection and power-loss resume for long, unattended production runs\u003cbr\u003e• Built-in AdWordCraft + MINGDA Slicer — font generation, vector import, 2D-to-3D conversion (Windows\/Mac)\u003cbr\u003e• CE\/FCC certified, with a warning light and emergency-stop button for shop-floor safety\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIdeal For: \u003c\/strong\u003eSign shops, LED channel letter and light box fabricators, outdoor advertising producers, and any shop\u003cbr\u003ethat needs to turn artwork into finished signage fast — without outsourcing\u003c\/p\u003e","brand":"Mingda","offers":[{"title":"Default Title","offer_id":46354153472034,"sku":null,"price":5499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0887\/6274\/4866\/files\/MINGDAAD-F4-k.png?v=1786222961","url":"https:\/\/machinexworks.com\/products\/mingda-ad-f4-3d-printer","provider":"Machinex Works","version":"1.0","type":"link"}
