Filament compatibility for the ELEGOO Neptune X: the materials it can handle, judged from its hotend, bed, chamber and enclosure. | Filament | Suitability | Notes | | :--- | :--- | :--- | | PLA | Great | The easiest filament to print. Works on almost any printer; a heated bed helps adhesion but is not required. | | PETG | Great | Comfortably in range (PETG likes a ~230-250C hotend and a ~70-85C bed). | | TPU & flexibles | With care | Possible, but a Bowden extruder makes flexibles harder - print slowly and prefer firmer (higher-shore) TPU. | | ABS & ASA | With care | The bed is hot enough, but ABS and ASA warp without an enclosure, which is strongly recommended for clean prints. | | Nylon (PA) | With care | Possible with care - an enclosure and very dry filament are essential. | | Polycarbonate (PC) | Not ideal | Not recommended - PC needs very high hotend temps and an enclosed chamber. | | Carbon-fiber & glass-filled | With care | Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle. | ### Best filament for the ELEGOO Neptune X Filaments the ELEGOO Neptune X prints well, ELEGOO's own first, then the best known. - [ELEGOO PETG](https://simplyprint.io/filaments/elegoo/petg): PETG, 220-250 °C - [ELEGOO PLA MATTE](https://simplyprint.io/filaments/elegoo/pla-matte): PLA, 190-230 °C - [ELEGOO PLA Plus](https://simplyprint.io/filaments/elegoo/pla-plus): PLA, 200-230 °C - [ELEGOO RAPID PETG](https://simplyprint.io/filaments/elegoo/rapid-petg): PETG, 220-250 °C - [Bambu Lab PLA Basic](https://simplyprint.io/filaments/bambu-lab/pla-basic): PLA, 190-230 °C - [Bambu Lab PLA Matte](https://simplyprint.io/filaments/bambu-lab/pla-matte): PLA, 190-230 °C - [SUNLU PLA](https://simplyprint.io/filaments/sunlu/pla): PLA, 190-230 °C - [Anycubic PETG](https://simplyprint.io/filaments/anycubic/petg): PETG, 230-250 °C ## Compare the ELEGOO Neptune X with similar printers - [ELEGOO Neptune 3 Pro](https://simplyprint.io/compatibility/elegoo-neptune-3-pro): Compatible, 225 x 225 x 280 mm, Also by ELEGOO · Similar build volume - [ELEGOO Centauri Carbon](https://simplyprint.io/compatibility/elegoo-centauri-carbon): Compatible, 256 x 256 x 256 mm, Also by ELEGOO · Similar build volume - [Bambu Lab P1S](https://simplyprint.io/compatibility/bambu-lab-p1s): Verified by SimplyPrint, 256 x 256 x 256 mm, Similar build volume - [Bambu Lab A1](https://simplyprint.io/compatibility/bambu-lab-a1): Verified by SimplyPrint, 256 x 256 x 256 mm, Similar build volume - [Compare the ELEGOO Neptune X with other printers](https://simplyprint.io/compatibility/compare?compare=elegoo-neptune-x#choose) ## Where to buy the ELEGOO Neptune X - [ELEGOO for Australia](https://simplyprint.io/buy/8302) (Official store) (Affiliate link) - [ELEGOO for Canada](https://simplyprint.io/buy/8301) (Official store) (Affiliate link) - [ELEGOO for the US](https://simplyprint.io/buy/8300) (Official store) (Affiliate link) - [ELEGOO's global store](https://simplyprint.io/buy/8303) (Official store) (Affiliate link) ## About ELEGOO 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: https://www.elegoo.com Openness: Mostly open (3.8 of 5) 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 (3 of 5): 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. - Local control and integrations (5 of 5): 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. - Third-party filament, slicers and parts (4 of 5): 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. - Repairs and spare parts (3 of 5): 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). - Data and privacy (3 of 5): 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. - Community and documentation (3 of 5): 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. ### Pros - Works on the local network with ElegooSlicer or OrcaSlicer, with no account needed. - Open-source slicer and a published RFID tag format for filament. - 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. - The Centauri Carbon's multi-colour add-on only became available in April 2026, after ELEGOO said in November 2025 it could not give a date. - Few complete Centauri Carbon parts are listed in its store. - The privacy policy is written mainly for the online store. ### Track record - May 2026: ELEGOO's parent closed a B+ financing round of over 500 million yuan (about $73 million) from investors including Meituan, Hillhouse Capital and Shenzhen Capital Group. It reported 2025 revenue of 2.3 billion yuan. - April 27, 2026: CANVAS, the multi-colour system for the Centauri Carbon, became available, five months after ELEGOO said it could not give a release date. - November 18, 2025: DJI and Hangzhou Jiangyu Technology became shareholders of ELEGOO's parent company, according to a business registration update reported by TechNode. The size of the stake was not disclosed. - November 2025: ELEGOO said the multi-colour system it was developing for the Centauri Carbon did not yet perform as it wanted and that it could not guarantee a release date. It offered owners a choice of a $50 filament coupon, a 365-day warranty extension or $80 off a Centauri Carbon 2 Combo. - September 26, 2025: In response to user feedback, ELEGOO published the modified source code of the Centauri series firmware on GitHub under GPL-3.0. - February 2025: ELEGOO opened pre-orders for the Centauri Carbon, its first enclosed CoreXY printer, on 17 February 2025.
