Open source 3D printer RepRap
RepRap is a 3D printer prototype (or 3D printer), which has a certain degree of self-replication ability and can print out most of its own (plastic) components. RepRap is the abbreviation of (replicating rapid prototyper). This prototype is free and open source from software to hardware, and is released under the free software agreement GNU General Public License GPL.
RepRap is a 3D printer designed and manufactured by Adrian Bowyer and others from the University of Bath, UK. It differs from the traditional flat printer in that it prints three-dimensional objects instead of flat surfaces. Yes, its printing materials are not ordinary ink, but ABS plastic, polycaprolactone, etc.
The original design goal of RepRap was for a very sci-fi purpose. It kept copying itself, and it was only some mechanical parts. This is also the origin of its name-RepRap is short for Replicating Rapid-prototyper.
RepRap can also be used to make things other than its own parts, such as door handles, coat hooks, wine glasses, etc.
RepRap is currently open source design, anyone can go to its website to download design materials, including circuit and mechanical parts, as well as the source code of the software.
There are currently three versions available for RepRap. The simple one is RepStrap "Seedling". The slightly more complicated one is RepRap "Darwin". The third version is called "Mendel". It has been released and you can download related materials. Darwin is constantly updating the design.
The working principle of RepRap is (Darwin is made of plastic as a raw material here, and there is also a laser version).The raw materials are heated and an object is erased layer by layer, which may require manual modification in the later period.
As an open source project, designed to encourage evolution, many derivative versions exist, and they can be freely modified and replaced by designers. The thermoplastic extruder of the RepRap 3D printer is generally installed on a XYZ platform with Cartesian coordinates controlled by a computer. The platform is constructed from steel rods and printed plastic connecting parts. All three axes are driven by stepper motors, a timing belt in the X and Y axes, and a lead screw in the Z axis.
The core component of RepRap is a thermoplastic extruder. Early RepRap extruders used screws driven by geared DC motors to firmly press the plastic material, forcing it to pass through a heated melting chamber and through a narrow extrusion nozzle. However, due to its huge inertia, the DC motor cannot start or stop quickly, so it is difficult to control accurately. Therefore, more recent extruders use a stepper motor (sometimes geared) to drive the raw yarn, pinch the spline shaft or knurled shaft between the raw yarn and a ball bearing.
RepRap's electronic products are based on the popular open source Arduino platform and other boards used to control stepper motors. The current version of the electronic product uses the Arduino-derived Sanguino motherboard, and an additional and customized Arduino board to make the extruder controller. This architecture can be extended with additional extruders, each with its own controller.
RepRap is regarded as a complete replication system, not a simple piece of hardware. To this end, the system includes a computer-aided design (CAD) 3D modeling system and computer-aided manufacturing (CAM) software and drivers in the form of RepRap user design into a set of instructions, through RepRap hardware, into a physical object.
It has developed two different CAM tool chains for RepRap. First of all, simply titled "RepRap Host", which is written in Java language by RepRap lead developer Adrian Bowyer. Second, "Skeinforge" was independently written by Enrique Perez. Both are complete tool chain systems that convert 3D models into machine language G-code for command printers.

Almost any CAD or 3D modeling software can be used with RepRap, as long as it is capable of generating STL files. Content creators can use any tool they are familiar with, whether the tool is commercial CAD software, such as SolidWorks, or open source 3D modeling software, such as Blender or OpenSCAD.
