GoKawiilRepRap project unveils µRepRap micro-fabrication 3D printer design
The RepRap open-source hardware project has released details of the µRepRap, a 3D printer built from common materials capable of micron and sub-micron positioning. Its latest 'PIKA' V0.02 hardware achieves roughly 1μm repeatable positioning and 10μm accuracy within an 8mm cubic work volume, and has been used to deposit UV resin droplets as small as 4μm and cure 9μm resin lines using a fibre optic probe. An earlier 'MAUS' variant, now deprecated, reached about 5μm positioning over a 4mm square area and remains fully documented with build files on Printables.
GoKawiil's interpretation of the reporting above, not reported fact.
Achieving micron-scale precision with inexpensive, widely available materials could lower the barrier for hobbyists and small labs to experiment with microelectronics and MEMS fabrication, areas normally requiring costly specialized equipment. Because the project builds on open hardware like The OpenFlexure Project's 3D-printed microscope platforms, it suggests a broader trend of open-source tools converging to enable low-cost precision manufacturing. The continued documentation and iterative versioning indicate an active community effort rather than a finished commercial product.
- µRepRap's PIKA V0.02 achieves about 1μm repeatable positioning and 10μm accuracy in an 8mm cubic volume.
- The system has deposited 4μm UV resin droplets and cured 9μm resin lines using simple probes.
- Built from common, accessible materials, the design draws on OpenFlexure Project microscope platforms and aims to enable home-workshop micro-fabrication.
