A Simple, Low-Cost Conductive Composite Material for 3D Printing of Electronic Sensors.[edit | edit source]

Leigh SJ, Bradley RJ, Purssell CP, Billson DR, Hutchins DA (2012) A Simple, Low-Cost Conductive Composite Material for 3D Printing of Electronic Sensors. PLoS ONE 7(11): e49365. doi:10.1371/journal.pone.0049365 http://www.plosone.org/article/info:doi/10.1371/journal.pone.0049365

"Rapid prototyping of electrically conductive components using 3Dprinting technology"[edit | edit source]

  • made of plaster-based powder bound layer-by-layer by an inkjet printing of a liquid binder
  • impregnated by a dispersion of carbon nanofibers (CNF) in epoxy resin
  • Surface resistivity of the model below 800 Ω/sq has been obtained when impregnated by a mixture containing less than 4 wt.% CNF. Volume resistivity of the molded and hardened CNF dispersion used for model impregnation have also been measured and a value less than 200 Ω cm has been obtained at 3 wt.% CNF content
  • carbon-black or metal powders increases the viscosity of the infiltrant so that it is not able to impregnate the 3D model structure
  • the average diameter of the fibers is 100 nm and typical length is 50–200 μm

"Inkjet Printing of Narrow Conductive Tracks on Untreated Polymeric Substrates"[edit | edit source]

  • Small conductive tracks are created by direct inkjet-printing
  • Ink with 30 nm silver particles onto flexible and transparent untreated polyarylate foils
  • Diameter as narrow as 40 micrometers
  • Conductivity is 13 to 23 % that of bulk silver
  • may be applied in plastic electronics

"Gravure printing of conductive particulate polymer inks on flexible substrates"[edit | edit source]

  • conductive lines on paper and plastic films
  • inks contained metal particles in an organic medium and were cured in temperatures of 70–120 °C
  • A printed resistance down to ∼50 mΩ/□ was obtained, with conductor lines 4–7 μm thick
  • thick ink layer is needed for high conductivity
  • printed antennas and inductors

"Reprinting the Telegraph:Replicating the Vail Register Using Multi-materials 3D Printing"[edit | edit source]

"April 12, 2012 RepRap Blog"[edit | edit source]

  • one Bowden extruder (for the plastic) and one "standard" extruder for the metal
  • Arduino compatible Sanguino board
  • plastic was printed before dropping in pre-tinned components and finally printing the metal tracks

[7]

"MetalicaRap"[edit | edit source]

  • electron beam based printer (an electron gun and vacuum chamber are the primary requirements for thin film solar cell printers)
  • Fully functional parts directly from standard metals
  • For most parts it may offer dimensionally finished metal parts IT grade 7
  • Good metallurgy on all common metals (Melting process rather than sintering process ensures near 100% of solid material)
  • Closed loop system
  • Self measurement of finished part tolerances.
  • May offer automatic self correction (subtractive machining steps during build process and feedback with compensation used in the additive process).
  • Can print thin film CIGS Solar cells in existing 10− 4 vacuum chamber with existing electron gun

"3-D Printing of Open Source Appropriate Technologies for Self-Directed Sustainable Development"[edit | edit source]

  • The ability to incorporate recycled metals into printed items would allow for the printing

of mechanically reinforced objects as well as switches and other electrically conductive applications

  • Fab@Home can print with conductive paste
  • Fab@Home can print electronics

"Towards cyclic fabrication systems for modular robotics and rapid manufacturing"[edit | edit source]

  • Extruder that extrudes low melting temp alloys into plastic parts
  • The Reprap group has demonstrated formation of circuit wiring by extruding metal into plastic parts
  • The extruder consists of a heated copper nozzle and a motorized syringe pump
  • Used to print metal coil plates

  • able to replicate full printer
  • print circuits
