WORLDTECHForget Trees, add Fins to your 3D Prints Instead
Single source: this development was reported by Hackaday. What WORLDTECH can establish is that the report was made, and by whom. It has not been matched against a second independent organisation and has not been officially confirmed by the organisations involved.
What happened
That said, [Matthew Trahan] figured that neither regular grid provides support for nor organic tree supports are the answer here, and that the better answer is found in fins . The fins are there to provide the support base, while small tines can be added to reinforce the connection to the model.
The problem with existing support approaches especially with FDM prints is that they can be fairly wasteful in terms of material, and they can leave serious marks on the printed object’s surface that require post-processing. These fins on the other hand are designed to require as little material as possible and snap off as cleanly as possible.
The basic concept was pitched by [Slant3D], who gets credited in the video below, although in their approach they used CAD software to add the fin provides support for manually. The tool, developed with the assistance of Claude, can either run locally or be accessed via printfins.com .
