You might also want to look at Resources . Perhaps some or all of that page should be merged into this page. (Discuss) This page attempts to make some sense, in general, of how all the pieces fit together to create a RepRap. However, if you want to skip all this stuff and get straight to getting your hands dirty then your best bet is to take a look at The incomplete RepRap beginner's guide and the build instructions category. In addition to those guides, you may also want to take a look at the links under the Models section below. RepRap Component Structure. That being said, to get a higher-level overview, we must start with discussing the different models of RepRaps, then go on to the four main components of a RepRap: The software toolchain. Models These days there are a growing number of many great and detailed build instructions for RepRaps! If you're steampunk or just like to get away without commercial kits, there are also RepStraps.

What is a Bowden extruder? | Start 3D PrintingStart 3D Printing One of the challenges when getting started with 3D printing is learning the terminology. Depending on your background, the various mechanical and project names may be complete gibberish. Fortunately, most of the ideas are pretty simple when you take a step back. For example, let’s look at the Bowden Extruder. In its simplest form, when someone refers to a Bowden-style extruder, what they mean is that there’s a flexible tube guiding the filament from the extruding motor (cold-end) to the nozzle (hot-end.) In fact, you can convert a “traditional”, direct extruder into a Bowden extruder by separating these two parts and running a tube (generally made of teflon) between them. The Direct Extruder The direct extruder is more common, and it’s easier to explain the Bowden variant in terms of its differences. (Source: wiki) The diagram above illustrates the workings of a typical, DIY extruder. (Image source: The Bowden Extruder Why go Bowden?

Improved Analog & Digital Interface with Arduino « Analog inputs with Arduino and EMC | Newest entries | Generating HAL files from Eagle schematics » Building on my earlier work , I've now improved the interface between HAL and the Arduino board to have: 6 10-bit analog inputs 6 8-bit PWM "analog" outputs 6 digital inputs/outputs (partition chosen when component is loaded) GPL license statement in source files As before, the driver consists of an Arduino Sketch ( halintf.pde ) and a HAL Userspace Component written in Python ( ). First, load the sketch (firmware source code file) in the Arduino GUI, compile it, and transfer it to the board. Now, if you don't already have it installed, install using apt-get or Synaptic Package Manager. Next, copy to the name (no extension) in a directory on your PATH. To demo it, in the sample hal script , change the line to reflect the serial port where the arduino is connected.

RepRapWiki TEDxEWB Talk: Adrian Bowyer at Imperial College, London, introduces RepRap RepRap is humanity's first general-purpose self-replicating manufacturing machine. RepRap takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that anyone can assemble given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend... RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. RepRap was the first of the low-cost 3D printers, and the RepRap Project started the open-source 3D printer revolution. RepRap was voted the most significant 3D-printed object in 2017.

Mendel User Manual General Powering up the RepRap Using RepRap How to print parts Designing things to make Converting a simple 2D image into a printed object See Mendel_User_Manual/Converting_a_simple_2D_image_into_a_printed_object for detailed instructions. More File:FFFDesignGuide.pdf If you are designing things to be made in RepRap, Ed's guide on to how to design for FFF above may be useful. Rather than design things completely from scratch, you might save a bit of time by starting from something in the Available Files and tweaking it to fit your needs.

Comment fabriquer ses filaments d’ABS pour son imprimante 3D à moindre cout Mon imprimante 3D devrait arriver d’ici une semaine, et je recherche déjà des techniques pour obtenir des filaments d’ABS à moindre coût. Lors de mes recherches, le projet Lyman Filament Extruder revenait souvent, mais il restais encore trop onéreux. Le projet de DeltaPrinter se base sur le projet de Lyman mais en utilisant que des éléments courants du commerce et une pièce imprimée en 3D. Cela permet d’obtenir un coup de revient de l’ordre de 100€, ce qui est de suite plus raisonnable. Le système est composé d’un tube de 10mm en acier inoxydable avec une ouverture dans lequel un foret à bois va faire l’office de vis sans fin pour pousser les billes d’ABS vers l’extrémité. Là, un bloc d’aluminium fait la jointure avec une tube de cuivre de 15mm de diamètre avec un embout percé et calibré au diamètre voulu. Le bloc d’aluminium est chauffé avec deux résistances chauffantes 230V à la température de 200°C.

ELM - DC Servomotor Controller This is an experiment on the closed loop DC servomotor control system (SMC). It will able to be used for practical use with/without some modifications. The closed loop servo mechanism requires real-time servo operations, such as position control, velocity control and torque control. Recently, most servo systems are using brushless motors called "AC servo motor" to reduce maintanance cost. Hardware Figure 1. Figure 2. Figure 1 shows the block diagram for SMC. Figure 2 shows the circuit diagram for SMC. JP1 is an ISP connector to program the AVR, and it can also used to attach an LED display board. Figure 3 shows the built servo controller board. Software Figure 4. Figure 4 shows the theory on the positioning servo mechanism. The servo operator consists of error amplifires and PID filters. The single loop servo control shown in figure 4 is called "Conventional servo mechanism". Figure 5. Figure 5 shows the servo operation for SMC. Position capture Figure 6. Internal processes for SMC
