SMMA and PCTG/PETG
Problem Phenomenon
Comparison of SMMA with PCTG/PETG transparent materials, selection decision.
Cause Analysis
SMMA competes with PCTG/PETG transparent materials; processability; cost; performance; application scenarios; selection decision.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
①Material comparison; ②cost analysis; ③performance assessment; ④application matching; ⑤selection decision.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
SMMA transparent material selection is a comprehensive decision; comparative analysis is the foundation; matching keeps value.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
