What happened
The RepRapMicron (µRepRap) wiki documents a home-buildable micron-scale fabrication machine derived from OpenFlexure microscope flexure stages. The current recommended build, PIKA V0.02, claims ~1µm repeatable positioning and 10µm-or-better accuracy inside an ~8mm cubic volume, depositing UV resin droplets as small as 4µm with a self-etched probe and curing 9µm lines with a fibre-optic probe; a 0.5mm 'Benchy' was printed at 4µm layer height. An earlier MAUS version reached ~5µm positioning over a 4mm square but is deprecated; the page was last edited Oct 13, 2026 and drew 198 points / 30 comments on HN.
Why it matters
If you prototype small mechanical, optical, or MEMS-adjacent parts, this is a documented bill-of-materials path to ~1µm positioning on an 8mm work area — worth reading before you request a quote from a commercial micro-CNC or lithography service. Treat the numbers as the author's own measurements on a wiki page, not independently verified, and note there is no AI/ML component and no Malaysian or SEA angle in the text.
Discussion angle
RepRap's promise was self-replication; µRepRap pushes it to micron scale with printed flexures — ask whether a 1µm, 8mm-cube machine in a home workshop actually changes who can prototype small parts, or whether the 8mm volume and unverified measurements keep it a hobbyist curiosity.
