ABS optical application limitation
Problem Phenomenon
[Problem phenomenon] Transparent parts needed, evaluating ABS feasibility
Cause Analysis
Ordinary ABS is opaque; transparent ABS (MABS) has light transmittance of about 85% but inferior to PC/PMMA; high optical requirements need material change; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
General transparency requirements select MABS; high optical requirements select PC/PMMA; balance light transmission and impact; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
ABS transparency relies on MABS, high optics switch to PC/PMMA; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
