Basics

  • A Dedicated Application of a "Laser Micrometer" or "Optical Micrometer"
    • Laser can come in 1-3 axis versions
    • Optical is only 1 or 2 axis
  • Uses rollers to guide the filament into the micrometer
  • Mainly used for closed loop control of the Filament Maker, but could be used for a FDM 3D Printer that can use inconsistant filament via real time adjustments of extrusion etc to match the varying diameter

To-Do

  • Look into if the mechanical versions can work
  • Look into DIY optical versions
  • Look into the cost of OTS versions
  • Figure out if this is optical or laser:
