Hello All. After running into these guys at the World Maker Faire in New York and getting into a long discussion about the printer, possibilities and more, the conversation drifted towards the possibility of Multi-Layered PCBs. I came up with a few ideas and they suggested that I ran them by y'all on the forum. Here goes... First idea: - Take a UV quick-curing fiberglass resin (possibly fiberglass repair goop) and apply a thin layer over the current circuit. If the fiberglass had a low enough viscosity, it could be sprayed on instead of having to be extruded. - After the fiberglass is applied, a UV light (preferably attached to the print head) would do a sweep of the board. - To bind the next layer to the fiberglass, a thin layer of quick-dry epoxy could be sprayed on top of the fiberglass. - Ideally, the printer would print into the layer of epoxy making it more secure and thinner (negligibly but still...). - UV light used again to cure the epoxy (hopefully UV curable) Second Idea: - Use a non-conductive adhesive that could be printed onto i.e. Industrial Grade double sided tape (can be purchased in 6 inch (or more) widths easily covering most boards) - The adhesive would need to be applied by hand so more babying would be required, but it would much less complex mechanically. Those are the current ideas. Have at it.
