# Kingroon KP3S V1: specs, SimplyPrint compatibility and setup > **Not expected to work** (Most likely not). We don't expect it to work, but we could be wrong. - By Kingroon, China - Launched February 2025 - Canonical page: https://simplyprint.io/compatibility/kingroon-kp3s-v1 ## Kingroon KP3S V1 at a glance The KP3S V1 is a small, low-cost open-frame bedslinger from Kingroon with a 180 x 180 x 180 mm plate and a high-speed claim of up to 500 mm/s. It suits hobbyists who want a cheap fast printer for PLA and PETG. - Build volume: 180 x 180 x 180 mm - Enclosure: Open frame - Max print speed: 500 mm/s - Motion system: Bed slinger - Prints well: PLA, PETG, TPU & flexibles ## Connect the Kingroon KP3S V1 to SimplyPrint | Way of connecting | Status | What you need | Notes | | :--- | :--- | :--- | :--- | | SimplyPrint | Not expected to work | | | | Klipper (Moonraker) | Not expected to work | | Kingroon advertises 'Klipper firmware' on a Cortex-A7 (Allwinner R528) board, but documents no Moonraker or web UI; owners can only read and write printer.cfg through ROOT G-code and a USB stick. Looks like a closed Klipper build, unlike the KP3S Pro V2/KLP1. ([Source](https://github.com/Matrix5435/Kingroon-kp3s-v1)) | | OctoPrint (Directly, over USB) | Not expected to work | | Klipper-based firmware on an embedded Linux board: no serial printing as shipped.

Filament compatibility for the Kingroon KP3S V1: the materials Kingroon lists for it. | Filament | Suitability | Notes | | :--- | :--- | :--- | | PLA | Great | On the maker's list of materials for this printer. | | PETG | Great | On the maker's list of materials for this printer. | | TPU & flexibles | Great | The direct-drive extruder feeds flexible filament well. Print slowly for clean results. | | ABS & ASA | Not ideal | Not recommended - the bed cannot reach the ~90-110C ABS and ASA need. | | Nylon (PA) | Not ideal | Not recommended - nylon needs a hotter hotend (~250-270C) and ideally an enclosure. | | 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. | ## When to choose the Kingroon KP3S V1 Choose the KP3S V1 if you want a compact, affordable high-speed printer for PLA and PETG and are happy with a small plate. Kingroon says it ships with Klipper, linear rails on X and Y, a direct-drive extruder and a 2.4-inch touchscreen, and sells it at 348.99 USD. It had no independent review in our research, and the page lists it as sold out. If you need a bigger plate, an enclosure for ABS, or a classroom printer, pick an enclosed machine instead, such as a Bambu Lab P1S. ### Pros - Low price for a high-speed printer, listed at 348.99 USD (Kingroon). - Kingroon quotes up to 500 mm/s and 10,000 mm/s² acceleration, and recommends 350 mm/s for everyday printing. - Direct-drive 3:1 BMG extruder and linear rails on X and Y (Kingroon). - Flexible PEI steel build plate, and Kingroon says assembly takes about 5 minutes. - Compact 180 x 180 x 180 mm footprint that fits on a desk. ### Cons - Open frame with no enclosure, so it is meant for PLA and PETG only (Kingroon lists those two). - Small 180 x 180 x 180 mm build volume. - Our catalog rates both Klipper and OctoPrint as unlikely for SimplyPrint, so it is not expected to connect, even though the maker page says Klipper. - No built-in camera in our facts, and the speed headline is a maker claim with no supporting test data. ### Who it suits - Schools: Not a good fit. An open frame with a fast moving bed leaves moving parts in reach, and it is not expected to connect to SimplyPrint for student approvals. - Hobbyists: Good fit. Cheap, fast and easy to set up for PLA and PETG, though the small plate and lack of an independent review hold it back. - Businesses: Not a good fit. Limited to PLA and PETG with a small plate and no enclosure, and there is no independent test of its reliability. - Print farms: Not a good fit. Without a camera, an enclosure or an expected SimplyPrint connection it is a weak choice for unattended fleets. ## Printers like the Kingroon KP3S V1 that work with SimplyPrint - [Kingroon KP3S Pro V2](https://simplyprint.io/compatibility/kingroon-kp3s-pro-v2): Compatible, 200 x 200 x 200 mm, Also by Kingroon · Similar build volume - [Kingroon KP3S Pro](https://simplyprint.io/compatibility/kingroon-kp3s-pro): Compatible, 200 x 200 x 200 mm, Also by Kingroon · Similar build volume - [Bambu Lab A1 Mini](https://simplyprint.io/compatibility/bambu-lab-a1-mini): Verified by SimplyPrint, 180 x 180 x 180 mm, Similar build volume - [LulzBot Mini 3](https://simplyprint.io/compatibility/lulzbot-mini-3): Compatible, 180 x 180 x 180 mm, Similar build volume ## Where to buy the Kingroon KP3S V1 - [Kingroon's global store](https://simplyprint.io/buy/8319) (Official store): Out of stock at Kingroon (Checked October 23, 2026) ## About Kingroon Kingroon is a Chinese company founded in 2016, with a Hong Kong address and a factory park in Huizhou, that made small, low-cost printers such as the KP3S bed slingers and the KLP1 CoreXY, the newer ones with Klipper installed. By October 2026 its shop lists its last printers only as sold-out clearance stock, and the company describes itself as a filament and resin maker. - Founded: 2016 - Headquarters: Hong Kong (registered address); production in Huizhou, China - Website: https://kingroon.com Openness: Mostly open (4.1 of 5) Klipper and standard parts make the printers easy to work on, but Kingroon now lists them only as sold-out clearance stock and some spare parts are out of stock. - Firmware and custom firmware (3 of 5): The KP3S Pro V2 and KLP1 ship with open-source Klipper on Kingroon's own all-in-one board. We found no Kingroon source repository; upstream Klipper carries a config only for the original KP3S. - Local control and integrations (5 of 5): The KP3S Pro V2 and KLP1 have Klipper on the mainboard with built-in Wi-Fi and print over the web or from a USB drive, with no Raspberry Pi needed. Kingroon's guides use Fluidd or Mainsail in a browser on the local network, so other software can use Moonraker's documented API. We found no Kingroon printer cloud or account; its guide points to the third-party Obico for remote access. - Third-party filament, slicers and parts (5 of 5): Standard parts throughout: MK8 and E3D V5/V6 nozzles and heater blocks, a Titan-style extruder, GT2 belts and 5015 fans. Any filament works, and OrcaSlicer ships profiles for the KLP1 and the KP3S family. - Repairs and spare parts (3 of 5): Kingroon still lists about 20 KP3S-family parts, including the mainboard, extruder and Y-axis rail, but several (the mainboard and rail among them) were out of stock in October 2026, and the printers themselves are discontinued. ### Pros - Klipper on small, cheap printers, controllable from a browser. - Standard, widely available parts (V6-type nozzles, GT2 belts, Titan-style extruder). - OrcaSlicer profiles for the KLP1 and KP3S models. ### Cons - Printers discontinued: Kingroon's shop lists them only as sold-out clearance stock (October 2026). - Some spare parts out of stock, including the KP3S mainboard and Y-axis rail (October 2026). - No published firmware source found for the Klipper models. ### Track record - October 2026: In October 2026 Kingroon's shop listed its remaining printers (KLP1, KP3S Pro V2, KP3S 3.0, KP5L) only as clearance items, all sold out, and its About page described the company as a maker of filaments and resins; KP3S spare parts were still listed, some out of stock. - 2023: Kingroon began selling the KP3S Pro V2 and the KLP1 CoreXY with Klipper installed on an all-in-one board, so no Raspberry Pi was needed.
