Bill of Materials up for #RepRapMicron. Total fastener count: 243, all M3. No wonder I exhausted local supplies!
The #RepRapMicron #3Dprinter has now been replicated, kinda. Documentation of assembly now complete. Bunch of files to upload to GitHub...
While documenting a section of the #RepRapMicron printer I found a bit that was sooooo scrappy I just *have* to ditch that part of the manual, do a redesign, reprint a bunch of parts, redo the manual. Darn.
Uses fewer M3 nuts though...
Alpha documentation for building a #RepRapMicron precision axis driver is up if anyone fancies preview/commentary.

Welp, 3 proposals accepted for #FAB25 in Czechia, and an unofficial #RepRapMicron build session. Going to be a busy bunny with that lot - filling in the workshop BOM's and paperwork alone is going to take a while. Oh, and there are 5 parties during the conference. Better get some practice in...
No Mad Scientist creation is complete without an eldritch purple glow.
#RepRapMicron can now control a weeny little resin-setting UV LED with M8/M9 GCODE, which in English means I can now in theory program the thing to automatically 3D print layered objects, and it can become a proper #3dprinter
Various people have spotted #RepRapMicron on a #FabLab chat group and want to make them. There's a conference coming up in a few months, and at this rate I'm going to be running an unofficial workshop!
To give an idea of the #RepRapMicron resolution I've put a human hair on the left. The #Fablab logo fits inside the hole in a Prusa printer nozzle.
Finally got the #RepRapMicron to do "Hello World" - about 1.3mm long. This is picked out in patches scraped out of a Sharpie layer at 30μm intervals using a PNG to GCODE program I wrote https://github.com/VikOlliver/RepRapMicron/tree/main/png_to_gcode
If anyone wants to read the #RepRapMicron #3Dprinter technical details and see what PrusaSlicer thought it was doing, blog entry here: http://blog.reprap.org/2025/02/esun-triangle-print-success.html
Re-ran #RepRapMicron #3Dprinter triangle print with eSun resin. The individual triangles are meant to have a 300μm base. The grid lines are 50μm (0.05mm). Contrast boosted.
The bloby #RepRapMicron prints had me questioning the behavior of the no-name resin (it literally turned up in a foil-wrapped jar from a kindly donor). So I got some eSun resin and trailed some out into thin lines manually. Yep, that behaves much better. Rematch coming up ...

The #RepRapMicron has printed ... something. It looked better before the resin cured, but this is the first attempt at printing a solid object. Each triangle is approximately 200μm (0.2mm) across. Excuse me while I have a moment.

Trying to #3dprint my first resin object with #RepRapMicron. Four 0.2mm equilateral triangles nested into one big triangle (for reasons). How did it go? Hellifiknow. I'm running a few in case I accidentally destroy one, and tweaking parameters as I go. This is what I see on screen for the very first one and it is at least triangle-like.
Tiny things, 500μm = 0.5mm . I've got the #RepRapMicron #3Dprinter drawing things as a series of dots. This is a prelude to actually make the thing deposit resin into a recognisable solid form using #Prusa's PrusaSlicer and a filter to slice the object model. The (awful) #python code for the filter is here if anyone can stomach it https://github.com/VikOlliver/RepRapMicron/tree/main/gcode_segmentation
The slightly fiddly process of preparing a microscope slide to make a resin reservoir and print bed for a #RepRapMicron #3Dprinter. Not too hard after about the third one.

Having made a SNAFU with the #RepRapMicron #3Dprinter print head that caused collisions with the microscope slide holder, I redesigned the deck completely. Now the slide is held down by magnets, and I can move it under the probe manually in 2D, which is very convenient. Plus I can get the tools, lights, camera etc. closer to the action too.

The #RepRapMicron is starting to morph from "some #3Dprinter Vik lashed up on the bench" into a reproducible project.

The Maus #RepRapMicron is morphing into a new form. The Metriccano prototyping system is putting the rapid back into rapid prototyping. One axis driver fitted, working on the second.

I had a rant about blogs and RSS at #EverythingOpen so for those who asked about #RepRapMicron it's at http://blog.reprap.org
When I've unpacked and petted the kittehs I'll post new stuff :)
