Kumiko is a form of Japanese woodworking that uses small cuts of wood (probably offcuts) to produce artful designs. It’s the kind of thing that takes zen-like patience to assemble, and years to master– and who has time for that? [Paper View] likes the style of kumiko, but when all you have is a 3D printer, everything is extruded plastic.

His video, embedded below, focuses mostly on the large tiled piece and the clever design required to avoid more than the unavoidable unsightly seams without excessive post processing. (Who has time for that?) The key is a series of top pieces to hide the edges where the seams come together. The link above, however, gives something more interesting, even if it is on Makerworld.

[Paper View] has created a kumiko-style (out of respect for the craftspeople who make the real thing, we won’t call this “kumiko”) panel generator, that allows one to create custom-sized frames to print either in one piece, or to assemble as in the video. We haven’t looked at MakerWorld’s Parametric Model Maker before, but this tool seems to make full use of its capabilities (to the point of occasionally timing out). It looks like this is a wrapper for OpenScad (just like Thingiverse used to do with Customizer) so there might be a chance if enough of us comment on the video [Paper View] can be convinced to release the scad files on a more open platform.

We’ve featured kumiko before, like this wood-epoxy guitar, but for ultimate irony points, you need to see this metal kumiko pattern made out of nails. (True kumiko cannot use nails, you see.)

Thanks to [Hari Wiguna] for the tip, and please keep them coming!

Cool. Could there also be structural applications for say light walls/doors of bicycle campers?

    So that video alone looks like it costs around $2700 to produce. The amount of work effort in this looks only slightly less than making an actual woodwork piece but the end result will still have a Legoy look up close. I absolutely applaud the work here, but the effort spent to end result does not equate to value for the large piece in my personal view. I'd rather pick up some extra shifts and purchase a $2700 piece of master crafted wood art than attempt this.

    5kg for 1.125^2^ square meters. About 50mm high/thick. $105 filament cost. Could be much less filament/print time with "speed holes" in depth. He also uses very dense "hexagon fill patterns". He put in an extra step to cover seams so it would not look lego-ey. Many alternate section joining techniques including raised front and back strips, and center patterns that lock sections without locking to each other.

    https://kumikowoodworking.com/design/ has this pattern: https://kumikowoodworking.com/products/tn-114/

    which is a strip design, and center sections could use a "center joint" with center patterns recessed from "strucutral stips"

    There is a guitar made from wood process that requires a lot of woodworking gear and much more assembling/fine tuning time, so this would be easier.
