Effector Redesign- PoC

We are looking into designs for n:1 filament i.e. multi filaments going into 1 extruder. 

  • Effector Plate re-design specfications:
    • Less weight & less inertia
    • Magnetic Balls effector plates and arms - Status: Completed
    • Automated hot-end tool changer. Status: The design was changed to an universal hot-end carriage where the magnetic ball arms have been connected to. A quick switching effector plate was then used to switch between 3D printing, Laser Exposure or Cutting, Other 3D Printing Head (such as chocolate extruder) 
      • Change hot-end heads -> This was redesigned as a two-in-one and three-in-one hot-end solution. This avoided the need to change extruder heads and have many heaters etc.
      • Change Laser cutter -> A magnetic quick switch laser cutter was perferred as at this time we saw no real need to switch between laser cutter,Exposing 3D printing within a single job. This may change once UV curing filament has been developed or if is going to be use with UV sensitive resin films
      • PCB Laser Exposure -> Status: Completed
    • Integrated layer cooling fan
    • Intelligent-Print-head : Status: In Progress
      • Integrated Arduino controller with serial, I2C connection to Rambo board for more local control and telemetry
      • Bluetooth or WLAN Telemetry transmission for remote analysis
      • Control of lighting
      • Control of Servo
      • Giro Sensors for telemetry Data ( MPU6050 , BMP180, and the HMC5883L)
      •  IR proximity sensor 
      • Multiple Servo control using 
      • Own power-source
      • Steppermotor drives for advanced clamping control
  • Single Bowden Extruder for multiple filaments: Status: Not Started
      • Single barrel drive hob Gear to drive multiple filamets
      • Servo controlled idle gear for selective pressure of filaments
  • Inductive Hot-End heater ->Status: In Progress
  • PEI Hotbed film -  Status: Completed
  • Auto-Levelling using LoadCell - Status: Completed
