HTP/PLA Hybrid 60% Hexagon Infill

All the parameters were the same as the first and second test except for the 60% hexagon infill. This test shows a slug of PLA exiting with the exhaust. Not good, as it could plug up the throat and cause an explosion. However, on my high speed camera, I counted six well formed shock cones which lasted less than a second before the ABS eroded. The next series of test will use a graphite nozzle with the parameters similar to the first test.
