The RepRapPro Ormerod 2 is a single-colour low-cost 3D printing machine that is a full open-source and self-replicating RepRap and is one of the most versatile 3D printers available. It is easy to expand in functionality, fast to replicate and fast to assemble. All the RepRapPro printers, including previous machines such as the Ormerod and Mendel, are capable of self-replicating their own plastic components.
The Ormerod 2 brings several advantages compared to its predecessor, including a much simpler and more integrated assembly with improved instructions and wiring looms for simple plugin connection and no soldering necessary.
Other improvements come in the areas of the build bed, the y-carriage design, bed probe, extruder and power supply, as well as better emissions control and software support. For example, the Ormerod 2 design offers much easier adjustment of the bed level; improved y-axis belt location and retention delivers easier adjustment of belt tension; and a new bed probe now features a four-wire differential device, as well as providing much easier access to the extruder for cleaning purposes.
In addition, the power supply is now a 100-240V worldwide input power supply and is a dedicated 12V supply, rather than being an adapted supply, and is more compact with its integration into the machine with no trailing wires. EMI emissions have also been reduced, resulting from a fully shielded design that meets the Class A CE mark.
Specifications of the Ormerod 2 printer include: build volume and speed of 200 x 200 x 200mm and 1800mm/min, respectively; a deposition rate of 33cm3 per hour; accuracy and layer resolution of 0.1mm and 0.01mm, respectively; and ability to print using either PLA or ABS thermoplastic materials. The open-source software designed to run the machine is fully compatible with the original Ormerod printer and will run on a relatively low powered computer running Windows, Linux/Ubuntu or Mac OS.
The RepRapPro Ormerod 2 is shipped ready for assembly as a kit of parts containing all the required components. The complete kit includes: all printed parts; all hardware, including threaded and smooth rods, screws, nuts, washers, belts and bearings; pre-soldered and programmed electronics; MicroSD card and adapter; heated PCB build surface; motors; nozzle assembly and extruder drive mechanism; 100m of 1.75mm-diameter white PLA filament material (weighing approximately 300g); a 100-240V worldwide input power supply (plugs available for EU, UK, US and Australia); plus open-source software to run the machine including firmware for the electronics.
The RepRapPro Ormerod 2 is now in stock at RS Components, priced at £499, as a kit of parts containing all the components required for full assembly.
RS is also now able to supply high quality 3D printing filament from Verbatim. Both the PLA and ABS filaments are available in 1.75mm diameter, while the PLA range is also supplied in 3mm diameter filament. Both are offered on 1kg spools and in an assortment of colours, including red, green and blue.
PLA (PolyLactic Acid) filament is a biodegradable bio-plastic derived from corn and is guaranteed not to include heavy metals or common chemicals such as phthalates and Bisphenol-A (BPA). ABS (Acrylonitrile Butadiene Styrene) filament is a co-polymer made from styrene, acryl and butadiene and is both impact resistant and tough.
