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:

- Github Page
- Notes:
- This uses an LED and a linear sensor array
- A SMD Camera (such as the Raspberry Pi Camera Module) may work as this?
- Also need to look into if a collaminator lens is of use for making the led light more collaminated
