hello
Lets all put our heads together and make this true.
I have sketched a few ideas on what this printer should do:
-create traces
- this could be achieved with standard copper strands from electric cables - flexible enough to be shaped in complicated shapes
- cheap -people can buy feets of cable and peel them,then spool each strand - cheap but tedious
-pads
- with some work can be made from the strands
Adhesive - very strong - only a very thin layer required,that dries slow and the bond is strong after curing
Longshots :
- vias
- multiple layers
Ideas so far
Substrate - well...a laminate of sort coated with contact adhesive in very thin layer
End tool for depositing strands
- thought of a syringe needle with a flared round tip or a small roll at the end
- plastic stopper to keep the strand still to make an angle
- cutting tool - should be sharp and thin,also not mess up the traces that are cut
- narrow - to avoid cutting into already laid traces
- fed through a bowden cable?
Software
- a 3d printer slicing model should do,modified to make only 1 slice/layer
- a script that reads common EDA files and calculates no. of strand to be aligned for wider traces
Issues so far:
- soldering not ruining the bond between substrate and traces
- aligning strands next to each other with good electrical contact
Goals
full open source and for modifyng
under 100$ complete cost
Since one man can only view a problem from one point of view,that is why i am trying to make this a community effort.
