10 Best 3D Slicer Of 2022

You are here, it means probably you’ve bought a 3D printer, or you may be keen on the 3D designing world. Before taking you into the world of 3D slicing software, let me introduce you to the basics of slicing.

A 3D slicer acts as a mediator between 3D design and a 3D printer to create a set of geometric codes or geometric paths. By understanding these codes, the 3D printer creates a model replica. Basically, a 3D printer can’t transmute a designed model directly into a print. Therefore, you need software to import your model into G-Code file format.

So, 3D slicer or slicing software plays a pivotal role between 3D models and 3D printers. It converts selected versions of the 3D model into a set of geometric codes (G- Code) recognized by the 3D printer. Whether they are files for 3D printing or laser cutting, a slicer will handle your files.

 Here, we are going to assist you in familiarizing yourself with the top 10 best 3D slicing software of 2021, including free as well as cost-effective paid slicing software. They are:

  • SelfCAD
  • Cura
  • Octoprint
  • Astroprint
  • Ideamaker
  • Repetier
  • Kisslicer
  • Simplify 3D
