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.
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.
来源
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.
优点
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.
缺点
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.
适合谁
学校不太适合
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.
业余爱好者适合
Cheap, fast and easy to set up for PLA and PETG, though the small plate and lack of an independent review hold it back.
企业不太适合
Limited to PLA and PETG with a small plate and no enclosure, and there is no independent test of its reliability.
打印农场不太适合
Without a camera, an enclosure or an expected SimplyPrint connection it is a weak choice for unattended fleets.
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.

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.
固件和自定义固件 ●●●●●
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.
[3][8]
本地控制与集成 ●●●●●
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.

第三方耗材、切片软件和零件 ●●●●●
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.
[5][9]
维修和备件 ●●●●●
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.

优点
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.
缺点
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.
实绩
十月 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.
[2][1][5]
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.
