Open Source FDM Pen

Basics

• A Handheld Device, that is similar to a Hot Glue Gun , but precise like a 3D Printer
• Also typically uses FDM Filament not "Hot Glue Sticks" (need to look into what material those are)
• Can be used for:
  • Art
  • Tweaks/Repairs to FDM Printed Parts
  • Joinery of FDM Printed Parts
  • Almost as a form of 3D Sketching

Layout/Part Planning

Brains/IO Module

• Has the power in ( USB-C DC power Delivery?, and filament in ports)
• Has some small pcb controller (needs 1 servo controller, and something to control the heaterblock, probably also something for indicator lights and/or a small display)
• Also all the needed power conversions etc

Extruder Module

• Has a OSE Extruder and a small motor (thinking those small hobby rc servos?)

Hotend Module

• Has a standard hotend, and the OTS exchangable nozzles

Control Methods

• Most likely integrated with the brains/io module?
• Could also use the usb-c to make a sort of "soldering station" like setup; a box with
  • Control Buttons/Dials
  • A Larger Screen
  • The Larger PCB
  • A Proper FDM Filament Spool
  • Also could have 6.5mm Jack ports or XLR Ports for using footpedals for feed control etc (see Open Source Universal Control Pedal )
