Klipper is an open source firmware for 3D printers that distributes the workload between a general-purpose computer (such as a Raspberry Pi [1] ) and one or more underlying microcontrollers on the 3D printer. [2] [3] The separation claims to allow for more advanced control compared to traditional firmware that runs solely on the printer's microcontroller. [4] Klipper supports multiple types of kinematics, including Cartesian, CoreXY and delta robot.

History

Klipper was developed by Kevin O'Connor [5] [6] in 2014. [7] One of the early adopters was the Voron project which built CoreXY printers with open-source software and open-source hardware. [7] Klipper's popularity has gradually increased over time, and in 2024 it came pre-installed on 3D printers from several manufacturers. [7]

In 2022, Klipper entered into a strategic partnership with BigTreeTech, a manufacturer of motherboards for 3D printers. [8]

In late 2020, Klipper introduced input shaping into the world of open-source 3D printing firmware. [9]

Features

As the host computer has more processing power and is capable of doing more intensive calculations, only the results of these calculations need to be sent to the microcontroller. This enables more precise control of stepper motors, [10] advanced kinematics, input shaping for vibration reduction, [11] detailed logging, use of macros, [12] and changing configurations in real-time without the need to restart the firmware.

The printer also has pressure advance, which is a parameter that compensates for the pressure build-up in the nozzle during acceleration for smoother and more precise printing. [13] It works by making the extrusion advance faster during strong accelerations, and advance slower during strong decelerations. This way, smoother lines can be achieved at high 3D printing speeds. The compensation is usually calibrated per material type (PLA, ABS, PETG, and so on), but can even be calibrated for each specific spool. The model takes into account the elasticity, viscosity, pressure and flow of the filament.

Supported hardware

Klipper supports several types of 3D printers and microcontrollers, [14] including boards from Arduino and STM32. It is compatible with many existing printers, and can be adapted to custom-built machines. [15]

Installation, configuration and interaction

Klipper is set up on a computer running Linux (such as Raspberry Pi), and in addition, appropriate firmware must be flashed onto the printer's microcontroller. Configuration is done through a text-based configuration file, which allows for customization and control of the printer's behavior.

To interact with Klipper, the user needs an interface. Two popular web interfaces are Mainsail OS and Fluidd. [16] Other options are OctoPrint [17] [16] or KlipperScreen. [16]

Development and society

Klipper is maintained and developed by an active community of users and developers. The project is hosted on GitHub, [18] where users can contribute code, report bugs, and read extensive documentation. There is also a dedicated forum, an r/klippers channel on Reddit, and a chat on Discord where users can get guidance with more common questions and problems.

In computing, firmware is software that provides low-level control of computing device hardware. For a relatively simple device, firmware may perform all control, monitoring and data manipulation functionality. For a more complex device, firmware may provide relatively low-level control as well as hardware abstraction services to higher-level software such as an operating system.

MakerBot Industries, LLC was an American desktop 3D printer manufacturer company headquartered in New York City. It was founded in January 2009 by Bre Pettis, Adam Mayer, and Zach "Hoeken" Smith to build on the early progress of the RepRap Project. It was acquired by Stratasys in June 2013. As of April 2016, MakerBot had sold over 100,000 desktop 3D printers worldwide. Between 2009 and 2019, the company released 7 generations of 3D printers, ending with the METHOD and METHOD X. It was at one point the leader of the desktop market with an important presence in the media, but its market share declined over the late 2010s. MakerBot also founded and operated Thingiverse, the largest online 3D printing community and file repository. In August 2022, the company completed a merger with its long-time competitor Ultimaker. The combined company is known as UltiMaker, but retains the MakerBot name for its Sketch line of education-focused 3D printers.

<span class="mw-page-title-main">Fused filament fabrication</span> 3D printing process

Fused filament fabrication (FFF), also known as fused deposition modeling, or filament freeform fabrication, is a 3D printing process that uses a continuous filament of a thermoplastic material. Filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the growing work. The print head is moved under computer control to define the printed shape. Usually the head moves in two dimensions to deposit one horizontal plane, or layer, at a time; the work or the print head is then moved vertically by a small amount to begin a new layer. The speed of the extruder head may also be controlled to stop and start deposition and form an interrupted plane without stringing or dribbling between sections. "Fused filament fabrication" was coined by the members of the RepRap project to give an acronym (FFF) that would be legally unconstrained in its use.

CoreXY is a technique used to move the printhead of a 3D printer or the toolhead in CNC machines in the horizontal plane. The advantage of this technique is that the two motors used to perform the movement in the horizontal plane are stationary and do not have to move themselves, which can result in less moving mass. Instead, drive belts are used which are connected in an intricate way to provide movement in a Cartesian coordinate system. Compared to conventional Cartesian 3D printers for fused filament, it can provide increased printing speed due to less moving mass.
