Ironing can make a huge difference in the surface finish of your 3D prints, but getting it right takes some careful calibration. At Southern Spark 3D, we take a methodical approach to ensure the smoothest possible results.

We start by testing our filaments with a series of test prints, tweaking ironing settings on each iteration. This allows us to see firsthand how adjustments affect the surface finish—from slight ripples to a perfectly smooth top layer. Our reference images show the dramatic improvement after just a few calibration rounds.

Each filament behaves differently, so we calibrate individually, adjusting factors like ironing speed, flow rate, and ironing temperature. By systematically testing and recording results, we can find the sweet spot for each material, ensuring every print has a flawless, polished look straight off the printer.

This multi-test approach is key to achieving consistently high-quality results—because a well-calibrated ironing process is what turns a good print into a professional-grade one.
