What Is Ironing in 3D Printing and When Should You Use It?

Ironing is a slicer feature that runs the hot nozzle over the top surface of a print after completing the normal top layers, at a very slow speed with minimal extrusion. The nozzle heat slightly remelts and flattens the top surface, filling micro-gaps between extrusion lines and producing a noticeably smoother finish than the standard…

How to Get Smooth 3D Print Surfaces: Every Method Ranked

FDM prints have visible layer lines. That’s the nature of the technology. Getting rid of them, or reducing them enough that they’re not visible at normal viewing distance, is achievable through a combination of slicer settings and post-processing techniques. Here’s every method ranked by effort and result. Method 1: Fine Layer Height (Easiest, No Post-Processing)…

Why Support-Free STL Files Are Worth Paying For

Supports-free STL files are one of the clearest signals of a well-designed file. Not every model can avoid them, but for hobby printing, a file that prints cleanly without supports saves time, materials, and the frustrating post-processing of removing support structures from visible surfaces. Here’s what to look for and why it matters enough to…

What Is Seam Placement in 3D Printing and How to Hide It

Every FDM print has a seam: the point where the printer starts and ends each perimeter loop. At this junction, there’s always a very slight imperfection where the extruder begins and stops depositing plastic. Where this seam lands on your print determines how visible it is. Seam placement is a slicer setting that controls this,…
