The Best Free 3D Modeling Tools for 3D Printing in 2026

You Don’t Need Expensive Software to Design 3D Models One of the most common misconceptions in 3D printing is that you need professional CAD software costing hundreds of dollars a year before you can design anything yourself. That has not been true for a long time. Today there is an excellent range of free 3D…

3MF file vs STL comparison showing why 3MF is better for 3D printing with embedded settings

What Is a 3MF File and Why Is It Better Than STL?

A 3MF file is a 3D model format that stores geometry, print settings, material information, and sometimes color data all in one package. It’s the newer alternative to STL and, for most modern FDM printing workflows, it’s the better format. This guide explains what 3MF contains, how it differs from STL, and when you’d choose…

How to Level a 3D Printer Bed: Manual and Automatic Methods

Manual bed leveling means setting the gap between the nozzle and bed surface at multiple points so the nozzle is the same distance from the bed everywhere on the print surface. Most modern printers handle this automatically, but understanding how it works makes troubleshooting first layer issues faster when automatic leveling isn’t producing the right…
