Hi
there must be a bunch of folk working on this PCB thing try'n to perfect the process with Lasers and InkJets thats for sure,
I have a cheapo Canon S200SPx Printer that comes apart in a nice way and will accept a PCB no probs would be a good starting point as the fram could easily mount up a Linear guide to support the PCB as I have a few double sided boards to do if the Ink Thing was sorted out, I tried a Permanent Ink from Artline Xylene Free stuff but it wouldn't flow very well from the P-Head it probably dried to quick & wrong viscosity as well..... anyway I soaked the P-Head in Denatured Alcohol and got it working again, just maybe I should try again with various Mixture's of Denatured Alcohol & Ink to get it flowing,
Has any one come close with mixing various inks etc ?
any Idea what all these Inks contain or where to get more info on them ?
I like the sound of the Direct Ink Printer as some of these are wax based ... needs more investigation,
last year at a Manufacturing Exhibition here in Jakarta I watched a Demo with a 3D Printer it Melted the wax as it was deposited onto the Table (Z Axis) and the Print Head (XY Axis) zipped about building up this Model, after each pass it shaved a tiny wisker off in preparation for the next layer, I wished that I had taken more notice of the brand of the Machine and the Wax it used the price was around SG$20,000 I remember, not the average Homebrewers deal !!

expose the Photoresist coating on a Presensitised PCB as I have a
small XY table that would be suitable for such a CNC venture, I was
looking at Duponts website and they talk about a UV Argon Laser for
LBI ...if the price was right it would be the ultimate Homebrew
PCB'ers dream http://www.dupont.com/pcm/riston/laserseries.html

The toner is transfered to the drum inside the laser and then to the
paper. the toner is moved and held in place with a slight electrical
charge. The copper of the board would stop the process.
But... there may be a way to cover the board with a non-conducting
film and print on that.
In my opnion, the best chance we have of a direct print is ink-jet.
They already make ink-jet printers for printing on things like belts
and hoses and metals and boxes.
It seems that we have just not found a good combination of printhead
and ink.
