GeekDoc 226 Posted July 4, 2013 Share Posted July 4, 2013 Has anybody seen this? http://www.marcoantonini.eu/doku.php?id=reprap:stencil Since I'm getting a fairly accurate 3D printer this winter, I'm hoping this is a viable technique! Quote Link to post Share on other sites
jpnorair 340 Posted July 4, 2013 Share Posted July 4, 2013 Looks interesting. I would be more confident if it could be PET rather than ABS, though. That said, I guess you should probably get one use for sure out of even ABS. Quote Link to post Share on other sites
username 198 Posted July 4, 2013 Share Posted July 4, 2013 Looks pretty neat, although i'd be quite surprised if they could manage 0.5mm pitch with that. Not quite sure 3D printing is the correct approach for stencils. I'd be pretty nice if someone made a nice cheap DIY laser etcher for stencils. =D Quote Link to post Share on other sites
Fred 453 Posted July 4, 2013 Share Posted July 4, 2013 I've not tried laser cutting stencils yet (as I'm still perfecting my PCB etching) but I'll give it a go soon. My eBay special is about as cheap as you can go for a 40W CO2 laser - about $800 after conversion to use Mach3 for control. I believe they've been used successfully for mylar stencils. I don't think any of the home made laser diode machines would have enough power to cut a stencil but I could be wrong. I'd imagine a single layer 3D print would very fragile and even a little porous. That links seems to prove it can be done though. Quote Link to post Share on other sites
