3D MicroG, Computational Thermal & Fluid Dynamics Laboratory Micro-Gravity Metal FDM

Micro-gravity Metal Fused Deposition Modeling NASA additive manufacturing Blue Origin rocket payload, with the University of Louisville Computational Thermal & Fluid Dynamics Laboratory.

3D MicroG Start-up Module

Abstract

This document is provided as a rough outline of requirements and additional details for the design of the 3D Micro-G module responsible for detecting the host vehicle’s apogee and commencing FDM prints during the target time-interval of flight. The content is ordered as follows:

  1. Definitions
  2. Mission Timeline
  3. ADDAM Requirements and Related Components
  4. Enumeration of ADDAM Components

1. Definitions

  • APW (Apogee Printing-Window) – the target interval of time after takeoff and before landing during which FDM print(s) are to be performed. (Roughly 5 minutes in length)
  • ADDAM (APM Detection and Data-Acquisition Module) – the module (hardware and software) responsible for detecting the onset (and conclusion) of APW, commencing the FDM print(s), and acquiring various non-critical data throughout flight

2. Mission Timeline (rough)

  1. Vehicle launches.
  2. ADDAM begins sensing for APW onset (and begins all other data-acquisition capabilities.)
  3. ADDAM detects APW onset.
    • ADDAM immediately commences FDM prints.
  4. Prints finalize during APW.
  5. APW ends.
  6. Spacecraft returns to Earth

3. ADDAM Requirements and Related Components

  • The ADDAM must, requiring no intervention, begin sensing for APW immediately upon power-on. (Power-on must occur prior to APW.)
    • Accelerometer to sense APW
  • The ADDAM may also acquire various environment metrics:
    • Visible-light spectrum video
      • Visible light spectrum light
      • Visible light spectrum camera
    • Infrared video
      • Infrared camera
    • Magnetic field (potential magnetic interference)
      • Magnetometer
    • “Real-time” timekeeping
      • If module is primitive (and time is too unreliable), potentially should be an external clock.
    • Amperage to and voltage across printer (or entire system)
      • Electronically interfaceable ammeter and voltmeter
  • Additional, Non-critical metrics
    • GPS NMEA sentences (altitude, UTC date-time, satellites tracking, etc.)
    • Ambient pressure
    • Ambient temperature (unless IR imaging suffices)
    • Relative humidity

4. Enumeration of ADDAM Components

Mission-critical:
  • Power supply
  • Accelerometer
Non-critical:
  • Visible light spectrum light
  • Visible light spectrum camera
  • Infrared camera
  • External clock
  • Electronically interfaceable multimeter
Very low-importance
  • GPS receiver
  • Barometer
  • Thermometer
  • Hygrometer (humidity)
