PC 3D Printing Applications
Problem Phenomenon
[Problem Phenomenon] High-strength heat-resistant FDM functional parts are required
Cause Analysis
PC filament printed parts have high strength and good heat resistance (HDT 140°C level), used for functional prototypes and tooling fixtures; printing is difficult and requires high-temperature equipment; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone
Solution
Select PC filament for functional parts; print with high-temperature equipment; design according to load direction; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate effective measures
Key Takeaway
PC printed parts are strong and heat resistant, the first choice for functional tooling; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
