The RepRap Pro Ormerod 2 is the latest RepRap self-replicating 3D printer from RepRap Pro. The machine is a faster to assemble, networked 3D printer with non-contact bed probe for full geometric compensation.
These pages are the complete instructions for building, commissioning and using the RepRapPro Ltd version of RepRap Ormerod 2. Like all RepRap machines, RepRapPro Ormerod 2 is fully open-source. It is licensed under the GPL. All the design files and software are available from the RepRapPro Ltd Github repository.
The RepRapPro Ormerod 2 is fitted with the open-source Duet electronics.
If you want to print the plastic parts for a RepRapPro Ormerod 2, see this web page.
- BEFORE YOU ATTEMPT TO ASSEMBLE ANY PART OF THE RepRapPro ORMEROD 2 3D PRINTER, PLEASE READ THESE BUILD INSTRUCTIONS FULLY AND ENSURE YOU UNDERSTAND THEM. Although all parts are covered by warranty, this will be invalidated by your not following these build instructions. You are building a complicated machine; many different skills are required to build, to commission and to operate a 3D printer. Try not to rush your build, or you may miss out something vital!
- Give yourself plenty of space and ensure your work area is clean. Dust and dirt are a 3D printer’s worst enemy.
- All printed parts have been printed on RepRapPro’s own machines. Despite the fact that these machines are highly tuned RepRap 3D printers, some holes and features may need a little fettling to get the best performance from the RepRapPro Ormerod 2. There is a video how-to on fettling 3D printed parts here on Vimeo.
- Before you start the build, please ensure you have all the components as listed on the packing list included in the kit. If anything is missing or damaged, please contact us through our contact page.
- We understand that people may want to change aspects of the machine’s design, and in fact we encourage this as it is one of the benefits of open-source development. Before changing anything, please be aware that the RepRapPro Ormerod 2 has been designed to maximise its build volume relative to the the machine’s footprint, and as such many of its components fit closely to others. So consider your changes carefully before you try to implement them. And when you find improvements, please tell us and the world so that we can include them in future kits, and so that existing owners can upgrade their own machines.
- The RepRapPro Ormerod 2 is a robust RepRap machine once assembled; however it does require a certain amount of care during assembly. If in doubt, force is usually not the answer! There are many ways to get support and advice; see below.
Ormerod 2 versions
Printing parts for Ormerod 2
If you have bought the hardware-only version of the Ormerod 2 kit, you will want to print the parts. You may also want to print spare parts for your printer. The list below shows the part number, part name, quantity and location of the parts. Parts are available as STL and SolidWorks files, and there should also be a STEP assembly of the whole printer.
For Ormerod 2, part number 528.0 to 528.4, the easiest place to get the parts is here: https://github.com/reprappro/Ormerod/releases
For 528.5 onwards, we use the part number, rather than the name of the part, for the file name. For the latest version of the parts, which should be backwards compatible with all the previous versions, see the Ormerod github repository. Some parts common to all our machines are in the Library github repository.
You can download the whole github repository, or download the parts individually; the ‘Location’ in the link below links to the stl page. This will also help you identify the parts. If you download the parts individually, make sure you download the ‘RAW’ version of the file; if you right-click on a link and download, you will end up with a file with the right name (with .stl on the end), but it will actually be an html document!
If you find you need help or advice with assembling, commissioning or using your RepRapPro Ormerod 2 3d printer, you can use the following channels:
- Check the instructions again; we are regularly updating them with feedback from our growing user-base.

Tools required for the build of the RepRapPro Ormerod 2 3D printer:
- Allen keys: 1.5mm, 2mm, 2.5mm, 4mm (the long reach type, with a ‘ball’ hex on the end, are very useful)

- 8mm (M5) socket and/or spanner
- 15cm adjustable spanner
- Fine tweezers
- Ruler, at least 300mm
- Fine-nosed pliers
- Drill: 2mm
- Hand chuck, pin vice or small electric drill
- Small, flat-bladed, electrical screwdriver
- Pencil sharpener
- Digital Multimeter
- Hot air gun, or cigarette lighter (or other heat source such as a gas cooker ring for heating PTFE heatshrink; a hair dryer is not sufficient)
For adjusting plastic parts, if necessary
- Drills: 3mm, 4mm
- Half round needle file
- Sharp craft knife
Nice to have, but not necessary
- 5.5mm (M3) socket and/or spanner
