ELEGOO is a Shenzhen company founded in 2015 that makes FDM and resin 3D printers, filament, laser engravers and STEM electronics kits. Its FDM range is the Centauri Carbon, an enclosed CoreXY printer, and the Neptune 4 series of open-frame Klipper printers, sold to hobbyists at budget to mid-range prices. DJI became a shareholder in 2025.

Founded: 2015 · Headquarters: Shenzhen, China · Ownership: Privately held through its parent, Shenzhen Zhinengpai (SmartPie) Technology; DJI became a shareholder in 2025 · Website: www.elegoo.com

ELEGOO is fairly open in daily use: its printers work over the LAN with open slicers and any filament, and it now publishes firmware source. Source releases have followed community pressure rather than launch, and spare parts for the newest printers are thin in its store.

Firmware and custom firmware
●●●●●		 The Neptune 4 series runs Klipper. For the Centauri Carbon, which went on sale in February 2025, ELEGOO published its modified source on GitHub under GPL-3.0 in September 2025, saying it did so in response to user feedback. [1][2][3][4]
Local control and integrations
●●●●●		 ELEGOO's printers connect to its slicer on the local network by IP without an account. The Neptune 4 series serves Klipper's web interface and Moonraker, which OrcaSlicer reaches as an Octo/Klipper host. For the Centauri Carbon and Centauri Carbon 2, ELEGOO published Elegoo Link on GitHub in January 2026, an Apache-2.0 SDK for local discovery, status, file upload and print control. The Matrix phone app adds remote printing while the printer is online. [5][4][16][6][17]
Third-party filament, slicers and parts
●●●●●		 Third-party filament works; ElegooSlicer is an open-source OrcaSlicer-based slicer, OrcaSlicer works with the Neptune 4, and ELEGOO published the data format of its RFID filament tags so others can use it. [7][8][4]
Repairs and spare parts
●●●●●		 ELEGOO sells hotend, extruder and nozzle kits and some boards for the Neptune 4, and its wiki has many replacement guides, including the Centauri Carbon motherboard. The store's Centauri Carbon parts list is short (hotend kit, touchscreen, upper shell). [9][10][11]
Data and privacy
●●●●●		 LAN printing needs no account; the Matrix app and cloud do. The privacy policy names the companies responsible for personal data in each region (Shenzhen, Hong Kong, United States) but is written mainly for the online store. [12][5]
Community and documentation
●●●●●		 Active community and a wiki with guides per model; firmware and slicer sources are on GitHub, although the Centauri Carbon source came after users asked for it. [11][7][1]
Pros
  • Works on the local network with ElegooSlicer or OrcaSlicer, with no account needed.

  • Many step-by-step replacement guides in its wiki.
  • Offered owners compensation when the Centauri Carbon multi-colour add-on was delayed.
Cons
  • Centauri Carbon firmware source came about seven months after sales began, after users asked.

Track record
