PCL 3D printing pen consumables
Problem Phenomenon
PCL children's 3D printing pens are low-temperature and safe, but strength and stability are insufficient.
Cause Analysis
PCL low-temperature printing at 70℃ is safe; but melt strength is low; printing stability; finished product strength; children's use scenarios.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Printing temperature optimization; ②Stability improvement; ③Strength evaluation; ④Safety design; ⑤Usage guidance.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The low-temperature safety of PCL 3D printing pens is an advantage; performance improvement is the direction; guidance ensures safe use.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
