Inaccurate color registration in PLA printing
Problem Phenomenon
The color registration deviation of PLA film during the printing process is large.
Cause Analysis
The thermal shrinkage of PLA film is large, and the tension and temperature changes cause dimensional changes and inaccurate color registration.
Solution
Reduce the printing oven temperature; stabilize the film tension; select low-shrinkage PLA film.
Key Takeaway
PLA printing registration requires thermal management.
