Curious as to weather it would be possible to combine materials ie. WSF and SS to create a 3D PCB?
Has anyone else consideres this. It could be used to incorperate the PCB into an enclosure and release product limitations from the dimensions of a flat PCB.index.php?t=getfile&id=13471&private=0

The two processes (WSF/SS) are dissimilar and can't be combined with the current technology at Shapeways.

Someday.. Someday.. (wistful)

Not only that, but SS doesn't solder very well and the electrical resistance is pretty high compared with copper traces. It's a nice idea though, and I'm pretty sure developers are working on printed electrical circuits. There are a lot of hurdles to overcome though.

Surely if SS can be printed copper would be viable?
Maybe a multiple head printer?

Do you mean Silver or Steel? The two are vastly different processes.

Steel is laid down in tiny granules that are then bound together before placing in a kiln to be "melted" together.

Silver is first printed in wax and run thru a lost-wax casting process.

Both of these production methods have enough heat that they'd melt WSF.

Maybe 2 parts, tracks and body, that clip together.
Just dreaming...

Oh, believe me.. I'm dreaming with you... or would that be called scheming?

Laser etching is usually the preferred method for custom PCB creation. A quick google for laser etched pcb will turn up all kinds of info.

Hope that helps.

I was thinking of a PCB that was a part of the design, enclosure, shape; rather than being a component to design around...
Quick model as an indication...index.php?t=getfile&id=13486&private=0

This could be on the inside, or snake around complex curves...

I think your bigger problem would be soldering square chips onto round or odd shaped PCBs. Plus most PCB's are multi-layered now days, and that would be really, really hard to do as a sphere.

It looks like some companies are trying to tackle it though...

A while ago I was doing some testing using methods to put a metal plating on printed plastic parts, and the method I was using is actually fairly common. By painting any object, even an organic one, with a silver conductive paint, the object becomes conductive enough to apply electroplating.

By selectively applying the paint to your traces you be able to copper plate them. You'd just have to join the traces with bridges temporarily so they are all connected, then cut the bridges after plating.

You can buy silver suspension paints on ebay. Here is one that has a whopping 60% concentration: http://www.ebay.com/itm/CONDUCTIVE-SILVER-PAINT-over-60-silv er-LARGE-30-grams-/270793802037?pt=LH_DefaultDomain_0&ha sh=item3f0c918135

You can find tutorials for electroplating online. The other ingredients are available locally. The copper chloride is at pool supply stores and sulfuric acid a.k.a. battery acid at auto supply stores (uh...be careful, wear safety equipment etc.). Build up those traces thick enough and you'll be able to solder it. You'll have to do it very quickly to avoid distorting the nearby plastic, so use a very hot soldering iron with a sharp tip. You could make some ok circuits, but using IC's would be pushing it unless you are really good with that stuff and have nice equipment like an ultrasonic soldering iron. LED lighting should be fairly easy.

I was thinking more of an entire printed part. If the components are too difficult to fit into compound shapes why not print custom components.
I'm not trying to achieve a goal I'm just interested in how 3d printing WILL change the way we percieve and create designs.
If these types of printing techniques are possible...

I think that dreaming of things that are currently impossible is a driving force to make them a reality...

I appreciate your dreaming, it may may inspire someone to come up with a way to do it, so more power to you.

I do think the printing of the components themselves is at the heart of this idea. They do have printed circuits now apparently, but the real jump will be when they can print diodes and transistors to make functional circuits. I can't wait!
