The resolution of a 3D printer will not be good enough for fine pitch components. A 0.4 mm nozzle will extrude a 0.4mm tube of melted plastic. That will be

imo, if you spend the money buy a brake, not a multifunction machine. If you can afford the expense, and do some metal bending work too, invest in a finger

I have used a cheap paper cutter purchased from one of the office supply stores. It probably is not the best idea for keeping it sharp since the glass fibers

I have one since quite a number of years. To cut a few PCB sit is expensive but I never tried as I cut them with a little table saw.! Here I can cut and bend
2016-01-25 by Stefan Trethan
I think a 22 gauge would go through a PCB just fine. ;-) Joking aside it s 0.8mm in real units and I m not sure if that is enough. It depends on cutting

For many years I used a carbide tile cutting scribe to score/snap PCBs. But with thinner PCBs they bend and distort. So a shear might be better. But they do

Thank you for the info. I will stay with my way as I don t have that type money nor that amount of boards to cut besides I get perfect results with diamond tip
2016-01-23 by Stefan Trethan
It depends on the angle of the shear blade. Professional PCB shears cut almost all the width at once so there is very little twisting of the material before it

Does a brake prevent cracks as my diamond tip saw blade does and is safe while using the proper push sticks and feather boards as I am always looking for new
2016-01-23 by Jean-Paul Louis
Keith, That make sense as 150 degrees is about the glass transition temperature of regular FR4. That was most likely to make clean cuts versus zillions of tiny

Where I used to work they used a metal shear like you cut a sheet of steel with by stepping on a pedal. They used to put the boards in an oven first maybe 150

Thanks for the heads-up. My etching will be done in an open-doored garage. At -18F, a little exothermic etchant might be just what the doctor ordered! :)
