3D printed solder paste stencil test 1 
I’m curious… How did you generate the model for the stencil?
I used eagle CAD. Isolated the top paste and dimension layer then exported as a dxf file and imported it to fusion 360 then i extruded the areas i needed printed to .2mm this was printed with a .4mm nozzle at .1mm layer height. Im gonna try my luck with a .25 and a .15 nozzle later on. This was really just a test to see if it could print.
Told you the export was easy. Gotta work that first layer up a little bit and you should get a consistent pad size. I’ve done it before. Just be prepared for .2mm in paste on every single pad
This is really awesome- great idea- I wonder how small the pitch can be- did you try any tests?
I really hope we have a breakthrough on filament recycling. Perhaps a material that lends itself to being recycled easily? I’ve printed some custom tools and that kind of thing as well, it’s a great use, I just wish I could easily recycle the stuff afterwards. I know there are machines, but they are very pricey, hopefully something changes in that regard.
@Ted_Huntington ​ with a .4mm nozzle you really cant do much the pins for the micro USB were all fused into a single cube lol. With a .25mm nozzle you get finer detail including the individual pins on the voltage regulator and battery charger. And with a .15mm nozzle you finally get the individual pins for the micro USB connector
@Cristian_Martinez oh ok thanks- still its a great idea
Hey if this doesnt work out ill go for the soda can solder paste stencils lol
I use a CO2 laser from ebay ($350) with transparency sheets and that works pretty well down to 0.5mm.
Im printing these cuz i dont want to spend money on stencils lol
