Tips for Success

Keep It Simple

Complex designs with thin details may not print well or may exceed the 25-minute time limit. Test your design in PrusaSlicer first.

Logo Legibility

Ensure the RTA logo is clearly visible and not covered by support material. Consider the logo's placement and size carefully.

Print Time Matters

Use PrusaSlicer's time estimate feature to verify your print will finish in under 25 minutes. Adjust infill, layer height, or design complexity if needed.
