PLA Workshop Exhaust
Problem Phenomenon
Lactic acid smoke and degradation gases accumulate in the PLA high-temperature processing workshop, causing personnel discomfort
Cause Analysis
PLA degradation produces irritating substances such as lactic acid smoke, acetaldehyde and acrolein; die head and workshop exhaust are occupational health requirements; smoke condensing on equipment surfaces also needs management
Solution
①Local exhaust at the die head; ②Workshop overall ventilation; ③Regularly clean the condensate on equipment surfaces; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PLA workshop gas management is an occupational health topic; local exhaust plus overall ventilation dual configuration; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
