3d printing with guided slew ring wire embedding

Bas de Bruijn, well known for his "pressure adjusted velocity controlled extrusion", made made this interesting wire embedding setup where a slew ring turned by a stepper motor connected to a 5th axis on the control board guides the copper wire in front of the extruder head. The wire is covered by extruded material and be shaped on a surface into various forms.





There are some obvious limitations: the wire has to be continuous, wire can not be cut, no possibility to connect the electronic components which make it unsuitable for making of electronic components. However, according to Bas,  it is quit suitable for other purposes like:

• Coils
• Antennas 
• RFID / NFC antennae
• PCB’s
• Flexible PCB’s (FPC’s)
• embed tubes and other filament types into plastic or other materials, like starch, organic printable stuff etc. etc.
• Use dissolvable PVA as an intermediate to bring wire/chips into tissue

Hopefully the project will be developed further!

Here are some attempts without the guide ring and with pre-positioned and fixated wire:

Don't forget Spoolhead project which tried to develop wire embedding toolhead for 3d printers:

Print results. It looks like nice small 3d printed antenna.

GCodePrintr loading g-code from NFC tag embedded in 3d printed object

Here is video demonstration of GCodePrintr interacting with NFC tags embedded in 3d printed objects. After the near contact the NFC tag emits link to URL that loads remote g code of the object in the software and you can print new copy.
Simply, you touch an object and you can print it using your smartphone.
I could see many use cases, like consumer goods where you can print simple replacement parts like handles etc. by scanning the NFC tag embedded in them.

Flomio embeds NFC into your 3d models

New service from Flomio that enables you to make your 3d printed models interact via embedded NFC tags. Effective for anti-counterfeiting, AR gaming solutions, marketing etc...

http://flomio.com/shop/nfc-tags/nfc-custom-3d-printables/

From their site:

Have a 3D solid modeled object that you want to print out with an NFC Tag embedded inside? We can help you with that.
We charge $0.50 per cm3 as well as a $4 handling fee per item. Additional is your NFC tag of your choice and shipping. Object build size must be larger than the NFC tag. We can print embedded NFC 3D objects as large as 15cm cubed.
Here’s out it works:

1. Send us your 3D solid model file (.stl format only).
2. Choose your build size, NFC Tag, and color plastic (white, green, or blue)
3. We price it out and if you’re happy, we 3D print it.
4. We test it.
5. We mail it to you.
