Electroforming is like electroplating, but deposits a thicker layer for making metal parts. As with electroplating, it's done by first creating a basic mold/mandrel to act as a substrate to electrochemically deposit the metal upon, in order to build up a metal part.
I propose a laser-catalyzed version
of electroforming for building metal parts. This would involve using a laser to enhance the electrodeposition wherever desired. Like a DLP resin printer, a base plate would still be required to build your metal part on top of, but a mold representing the shape of the desired part would no longer be required, unlike with electroforming. This is because the electrodeposition would be controlled by the laser-catalysis, with the laser being steered/directed digitally, like in a laser DLP 3D printer.

Electroformed parts are more solid and more consolidated, because they are built by deposition of ions. This is in contrast to SLS (selective laser sintering) which is building layers of particles on a particle bed and fusing them together. |

@a1: please see links I posted under my main submission |

The advantage is in the flexibility allowed by a steerable laser, which allows you to achieve any part geometry you want, independent of the need to create a mandrel. So yes, you'd be building/depositing your model onto the base plate, just like a 3D printer does, and there'd be no mandrel. Otherwise, depositing onto a mandrel could impose limitations on geometry. |

Another thing - the laser electrodeposition metal printer has a similar architecture as a DLP resin printer, and only uses a flat thin layer of liquid ionic solution in contact with the base plate in order to form a part on it. This is in contrast to the classic method of electroplating/electroforming, which requires a large 3-dimensional tank containing the liquid ionic solution for the 3D mandrel to be immersed in. |

I didn't read both ideas in enough detail to tell the difference. Could you summarized the difference between this new idea and the old one [link]? |

Sorry, I forgot that I'd submitted the idea before. Yeah, I've had my mind on this for some time now. |
