What Is a 3D Slicer & What Does It Do?

A slicer is 3D printing software that converts digital 3D models into printing instructions for your 3D printer to create an object. The slicer cuts your CAD model into horizontal layers based on the settings you choose, and calculates how much material your printer will need to be extrude and how long it will take to do it.  All of this information is then bundled up into a GCode file which is sent to your printer. Slicer settings do impact the quality of your print so it’s important to have the right software and settings to get you the best quality print possible.  (via pinshape Blog https://pinshape.com/blog/3d-slicer-settings-5-things-you-need-to-know-about-3d-printing-software/)
