RepRapPro debuts Atmel-powered Ormerod 3D printer

RepRapPro has debuted a new Atmel-powered (SAM3X8E ARM Cortex-M3) RepRap 3D printer kit that can be assembled in just two hours. Aptly dubbed “Ormerod,” the versatile printer kit is named after the famous entomologist Eleanor Ormerod.

According to, the Ormerod 3D printer features a heated bed, lightweight high-powered hot-end with an integrated cooling fan (ducted to cool the top of prints), a simple elegant drive for 1.75mm diameter filament, a pre-assembled wiring loom and an industry-standard ATX power supply.

The Duet (Ormerod board) is equipped with both USB and Ethernet ports, allowing Makers to drive the platform with a conventional RepRap app like Pronterface or control the platform via a standard web browser. The new RepRap’s firmware also features bed-plane correction and orthogonal axis compensation.

Additional key specs include:

  • Open-source self-replicating RepRap
  • Uses the same chip as the 32-bit Arduino Due (Duet electronics, Atmel SAM3X8E ARM Cortex-M3)
  • IR probing for self-aligned printing – no bed adjustment required
  • Build volume: 210x190x140mm
  • Overall size: 500x460x410mm
  • Working volume of 200 x 200 x 200mm
  • Printing materials: ABS, PLA, 1.75mm diameter thermoplastic
  • Build surface: PCB-heated bed to reduce complexity of assembly and to ensure parts do not warp
  • X-carriage: Three Z-adjustable deposition head mounts; one head supplied
  • Standard nozzle size: 0.5mm
  • Accuracy: 0.1mm
  • Resolution: 0.0125mm
  • Building speed: 1,800 mm/min
  • Moving speed: 12,000 mm/min
  • Deposition rate: 33 cm3 / hr
  • Motion: Linear ball bearings on X and Y axes, Igus low friction bushings on Z axis
  • Pre-soldered electronics with built-in microSD card slot for standalone printing
  • Enhancements to the printed parts to improve the ease of assembly of the X and Y axes

“When I started the whole RepRap project I thought that it stood a chance of working. By working, I mean that if you were to put the machine together it would print its own plastic parts,” said RepRap creator Adrian Bowyer.

“But I didn’t expect there to be scores of RepRap-based companies all over the world just a few years later, and to be helping to run one myself. So RepRap also works as a global social and economic phenomenon, as well as an engineering success.”
