Kingroon KP3S Pro V2
About the Kingroon KP3S Pro V2
Kingroon KP3S Pro V2 is a high-speed cantilever printer with linear rails. The print volume is a 200 mm cube and uses an MKS Pi motherboard to run Klipper. The extruder is a 9.5:1 dual metal gear extruder, and the hot end uses a ceramic heater. The print head has an accelerometer built-in for input shaper calibration, and there is an inductive sensor for auto bed leveling. The printer supports Ethernet, Wi-Fi, and USB drive printing. The maximum speed is claimed to be 500 mm/s, and the recommended print speed is 350mm/s with 10,000 acceleration. The power supply is 300 watts, and it uses a small monochromatic LCD screen instead of a touch screen. A sub $300 price with Klipper firmware, automatic bed leveling, and linear guide rails on all axes is still fairly appealing considering some of the issues users have experienced. It’s not uncommon to arrive with a miscalibrated extruder and a loose fan duct. This version does not have a filament sensor, and users have reported issues with the firmware versions and upgrading firmware.
Benefits of the Kingroon KP3S Pro V2
Modern mainboard features - Many 3D printer features relate to the version of the mainboard and firmware, including features like resuming prints after a power failure and support for silent stepper motor drivers for quieter printing. Newer boards also include safety features like thermal runaway protection which shuts the printer down if it detects issues with overheating.
Easy to assemble - This 3D printer is shipped with most of the parts pre-assembled, and you will only need to attach a few components and connect a couple cables in order to get the machine ready to print.
Carborundum glass bed provides good adhesion and easy removal - Carborundum glass is a great build surface that provides good adhesion while heated, but parts can be removed easily once it cools. The surface finish is not quite as smooth as borosilicate glass, but the superior adhesion without any hairspray more than compensates. With a carborundum bed, you wont need to use any additional adhesives like hairspray, but it is important that you clean the bed with a damp cloth after every 5-10 prints to maintain the adhesion.
Direct drive extruder - Direct drive extruders are mounted right above the hot end, and push the filament directly into it, as opposed to a side mounted bowden extruder setup. We prefer direct drive extruders to bowden since they are less prone to jamming and typically require less maintenance. they also are much easier to use with flexible materials
Affordable - This printer does not include a lot of frills, but offers a good experience for a low price point. While this low price means you won't be getting the most premium features, you can still get a lot out of these machines if you are willing to put up with some missing quality of life features.
Wireless printing - In addition to the standard USB and SD card connections, you can connect wirelessly to this printer to print from your computer or mobile device.
Linear rail motion system - Linear rails provide added stability to the moving parts of the printer, allowing higher printing speeds without sacrificing quality. Keep in mind that the most important factor to consider when optimizing for print speed is the flow rate of filament, which depends on the hot end and nozzle size moreso than the motion system.
All-metal hot end - An all-metal hot end allows for printing at high temperatures up to 300C, while standard hot ends are capped at 260C before the PTFE material begins to degrade. All-metal hot ends are also less susceptible to jamming, and do not degrade as fast.
Dual gear extruder - A dual gear extruder grips filament from both sides and can exert much more force on the filament before slipping. It helps with all filaments but especially with flexible, slippery TPU.
Disadvantages to consider
No touch screen - having a touch screen isn't a deal-maker or breaker, but it is a convenient feature that makes it easier to navigate the interface when you are printing files and configuring 3D printing settings.

Brand Summary: Kingroon
Founded in 2015, Kingroon focuses on creating user-friendly 3D printers at affordable prices. Their printers come partially assembled with clear instructions, making them a good choice for beginners. Features like automatic bed leveling on many models further simplify the setup process. Kingroon strives to offer a complete 3D printing experience, but it's important to consider potential drawbacks. Customer support can be inconsistent, and unlike some competitors, Kingroon doesn't have a dedicated forum or user group. This lack of direct support might be a hurdle for those who prefer readily available assistance. However, the broader 3D printing community online offers a wealth of resources and helpful users who can answer questions and troubleshoot issues. Overall, Kingroon printers are a solid option for budget-conscious beginners and hobbyists who prioritize affordability and user-friendliness. They should be comfortable navigating online resources for troubleshooting or seeking help from the wider 3D printing community.
