Printing with Phrozen EL400 Resin

To achieve the best results with Phrozen EL400, it’s essential to follow the recommended printing guidelines. Here’s what you need to know:

Recommended Printing Settings

• Layer Thickness: 100 µm
• Wall Thickness: ≥ 1.5 mm
• Lifting Speed: 120 – 150 mm/min
• Support Thickness: 1.0 mm or ≥ 1.2 mm

Pro Tips:

• Printing on the Build Plate: To minimize deformation, it’s recommended to print models directly on the build plate. If supports are necessary, ensure that gaps are wide enough for the resin to cure properly.
• Adjusting Speed: Reducing lifting and return speeds while increasing rest time can lead to more successful prints, especially for complex models.
