Resin 3D printing, significantly the MSLA (masked stereolithography) course of, has exploded in reputation over the previous couple of years. Resin printing is understood for producing very detailed and clean fashions with nearly invisible layer strains, however was too costly for many hobbyists till comparatively not too long ago. Now, cheap LCD panels and UV LED gentle arrays have pushed the prices down lots, with small fashions generally dipping beneath $100. However what for those who needed to go actually small? That is what YouTuber My N Mi did with this useful resin 3D printer smaller than your thumb.
That isn’t hyperbole. This whole 3D printer is across the similar width and depth as an grownup man’s thumb, and is definitely fairly a bit shorter. The general dimension is 18x31x41mm. And until My N Mi is pulling some actually intelligent digital camera tips, then it’s also utterly useful and able to printing resin elements. The construct quantity is simply 11x11x17mm, which signifies that it’s restricted to printing ridiculously tiny elements. However that simply provides to the mystique.
Sadly, we all know little or no concerning the technical particulars. My N Mi says that the XY accuracy (presumably the pixel dimension) is 0.135mm and that the Z decision (layer thickness) is 0.005-0.03mm. The latter is regular for an MSLA printer, however the XY decision is poor — although nonetheless ok for some first rate prints. The body is a few form of wooden, however we do not know every other particulars concerning the elements used. The Z axis has twin rods and a few form of screw, which is about all we will see.
We will, nevertheless, make some inferences. There may be in all probability a small LCD panel with the backing eliminated to make it clear. The sunshine in all probability comes from a single UV LED. And it in all probability makes use of a small microcontroller for management. Hopefully My N Mi will submit some extra particulars sooner or later, as a result of we might like to know what’s going on inside this miniature 3D printer.
