General tools and equipment

  • 3D printer

    All components of this project were printed on a home-built Makerfarm Prusa 8" i3v. Presumably, a commercial printer will provide comparable (or more likely, superior) print quality.

  • Filament

    Builds were tested with PLA (eSun) and PETG (Gizmodorks). The latter is preferred due to its increased chemical resistance relative to PLA and the structural performance (it is less brittle).

  • M3 hex key and wrench

  • Exacto knife

  • Sandpaper

  • Adjustable wrench

  • Needle nosed pliers

  • Helping hand with magnifier or dissecting microscope

syringe pump

  • 1/4" steel rod, 140 mm length, (2)

  • 1/4"-20 TPI threaded steel rod, 155 mm length (1)

  • 5V DC small reduction stepper motor from Adafruit.

  • M3x10 hex-bolts (4)

  • M3x16 hex bolts (2)

  • M3x25 hex bolts (3)

  • M3 hex nuts (12)

  • 1/4" 20 TPI nuts (3)

  • 1/4" 20 TPI jamnuts (2)

  • Syringes

    The default configuration uses a 3-mL HSW luer slip eccentric syringe which can be found at Restek although I purchased my batch from Fisher Scientific (and they apprently no longer sell them). A different syringe can be used by adjusting the parameters in the global file.

fluidics system

  • flexible tubing with an outer diameter of approximately 1.8 mm
  • quick-setting epoxy

controller

  • Arduino Uno or similar
  • L293D dual H bridge or similar
  • hookup wire
