CR-PETG, a premium 3D printing material that combines the low shrinkage of PLA and impact resistance of ABS. This guide will help you maximize the advantages of CR-PETG to create both practical and durable prints.
CR-PETG with its excellent performance is particularly suitable for:
❌ Ultra-high precision models (PETG tends to string, less detail than PLA)
❌ Long-term use in high-temperature environments (may deform above 70°C)
For optimal printing results, consider these settings:
230-250°C (recommend starting at 240°C, too low causes layer separation, too high causes stringing)
60-100°C (recommend starting at 80°C)
40-80mm/s
0.1-0.3mm (depends on required precision)
50-100% (adjust as needed)
Bed preparation: Use PEI sheet or apply small amount of PVP glue, avoid over-adhesion
· Z-offset slightly higher than PLA (about +0.05mm)
· First layer speed ≤20mm/s for better adhesion
· Enable retraction
· Lower temperature by 5-10°C if necessary
· Z distance at 0.3mm
· Consider using tree supports
If material is damp, dry at 60-65°C for 4-6 hours
Keep sealed, PETG is hygroscopic
Avoid over-adhesion which may cause difficult removal
Enclosure not mandatory but helps reduce warping
Can be sanded (400-800 grit), bondable with epoxy
Ensure certification for food contact applications
Avoid prolonged use above 70°C to prevent deformation
CR-PETG is a cost-effective, durable multipurpose material suitable for functional parts, outdoor items, and food containers. Key factors are proper temperature, retraction, and cooling settings. Check material dryness and adhesion when problems occur. Keep purchase proof for warranty service and contact official support if needed.
