Underground Gadget Master Speaks at Nanotech Scale
Swapping gears to the miniature realm, here's the lowdown on a compact 3D printer named μRepRap that pushes the boundaries of micro-scale printing. This bad boy, showcased by Vik Olliver over on the RepRap blog, is all about precision, aiming for micron-level accuracy in its prints.
The blueprint of the μRepRap closely resembles the OpenFlexure microscope, using 3D printed flexures to create ultra-precise XYZ movements necessary for those minute movements required for micron-level printing. Despite being at an experimental stage for printing simple objects, the microscopic scale of this creation is mind-blowing.
Recently, [Vik Olliver] has successfully printed a triangular pattern in resin at a total size of 300 μm, a feat that leaves many commercial SLA 3D printers in the dust. Furthermore, the potential of this technology extends to printing small-scale circuits using conductive resins, although fine-tuning the resin could be a necessity.
In addition, the μRepRap isn't just limited to printing resin. As demonstrated on the RepRap blog, it can also crack out designs in marker ink, as evidenced by the print of our own Jolly Wrencher! Given its size of 1.5 mm, the detail it manages to produce is nothing short of remarkable.
If you're intrigued and eager to give the μRepRap a go, head on over to [Vik Olliver]'s GitHub for the blueprints. The μRepRap project has been a work in progress for quite some time, with the design undergoing several changes since its inception. For those interested in the early beginnings, check out an older version of the μRepRap based around OpenFlexure! Just remember, for the latest advancements and updates in this field, it's best to keep tabs on the RepRap blog or the wider RepRap community directly.
