Is 3D Printing Safe? or DIY Testing for HCN from ABS and Nylon 3D Print Material


Step 5: Equipment Setup for Dynamic testing

Picture of Equipment Setup for Dynamic testing
The following are measured per the photo:
  1. Heater Block Temperature - This is what will heat our plastic samples
  2. Exhaust Temperature - This is just to show that the temperature is increasing as a thermal affect of air flow past the heater block.
  3. Heater Cartridge AC Voltage - This is used to adjust the voltage up in steps - 50, 60, 70, 75, 80, 85, 90, 95 and 100 volts AC
  4. Time
  5. Smoke and Carbon Monixide Detector
  6. HCN measurement of emissions
  • 1 each Column
  • 1 each variac
  • 1 each clock = any
  • 1 each Smoke Detector = Any Combination Smoke and Carbon Monoxide Alarm
  • 1 each Digital Voltmeter = Cen-Tech 90899
  • 2 each Digital Voltmeter = Cen-Tech P37772 w/K Thermocouple
  • 1 each HCN Sensor = Industrial Scientific T-82 or equivalant
  • 1 each test sample
