Key points in selecting equipment for NVO and BVO selection
Before choosing operating conditions for NVO and BVO selection, define the observable material result and the actual load.
Compare NVO and BVO fan modes and pressure transitions using powder or tray loads as appropriate.
Equipment decisions
-
Describe scale-up using usable tray area, part layers, spacing and thermal load per batch; nominal-volume ratios do not directly predict throughput.
-
Retain the material endpoint and sample-temperature window from laboratory trials, and remeasure heating, evacuation, purge and cooling times in the larger chamber.
-
Compare lab and pilot results at the most challenging load positions, then assess accepted output per batch and complete cycle time.
Trial and acceptance
Record the initial sample condition, loading layout, recipe version and raw measurements. Agree the acceptance endpoint before the trial; repeat at challenging load positions and compare the finished material result.
