What Is the Best 3D Printer Slicer in 2022?

The process of 3D printing comprises three essential components: the 3D printer, the 3D model, and the slicing software for 3D printing. If you're new to 3D printing, a 3D printer slicer, or slicer, is software that acts as the middleman between the 3D printer and the 3D model.

3D printer slicers convert 3D models (like STL) into a format (like G-code) that 3D printers understand and can trace to create a print. The G-code file contains a set of instructions that tell the 3D printer what to do and how to do it.

This article covers some of the best 3D printer slicer software. But first, let's look at the characteristics of a good slicer.

What Are the Qualities of Good 3D Printer Slicer Software?

To be considered great, there are some features an industry-standard slicer should have. Here are the main variables to consider when searching for the best 3D slicer.

1. Ease of Use

There's no point in having great and advanced features if no one can find and use them. An ideal slicer should have a user-friendly interface and straightforward guides.

2. Preview

A good slicer should provide estimates on the printing time, how much material is needed, and how much is left. The estimations should be as accurate as possible.

3. STL Import Speed

You don't want to waste time waiting for your 3D printer files to display. Any good 3D slicer should quickly import STL files (or any other 3D printer model), no matter the size or complexity of the files.

4. STL Repairing

If your file has errors that could affect the print, a good 3D slicer software will alert you and fix them if necessary. This helps prevent wasteful reprints.

5. Slicer Supports

A good slicer should automatically generate supports. This will ensure that your final print is more precise and accurate, especially over wide-angle printing.

6. Cost

There are many great free programs, so if the 3D printer slicer is paid, it should offer significant advantages over the free options.

Slicing Software

A 3D printer cannot convert the 3D model directly into a print. It needs a geometric interpretation of the model and a slicing software does just that. A slicing software or simply a Slicer converts a 3D model into a set of geometric codes or a set of paths which the 3D printer understands and can trace to create the print.

A slicing software is a necessary mediator between the CAD file and the printer.

Prusa Slicer

Prusa Research, the company behind the original Prusa 3D printers, has developed its own slicer, PrusaSlicer, based on Slic3r, an open source slicer. PrusaSlicer has gained a lot of popularity very quickly for a number of reasons: not only does it have a large list of Slic3r's adjustable settings, but it also has some handy features that the original software didn't have.

With a redesigned interface, built-in support for Prusa's own range of printers, and user-friendly settings for a range of common media, there are many improvements over the original software. Key features include customizable supports, support printing with different materials, and flexible layer height settings.

PrusaSlicer can be used to cut models for both FDM printers and photopolymer 3D printers. It has various modes allowing you to edit the settings depending on your experience, and the Expert mode opens up a huge list of customization possibilities. However, even simple profiles can work well in PrusaSlicer. There are fewer printer presets than some other popular slicers, but it's just as easy to set up or import custom settings.

Based on Slic3r, PrusaSlicer supports most of the original features and even accepts Slic3r configuration packages when importing profiles.

Looking for 3D printing software? We've rounded up the top 20 software tools for beginners and professionals alike. Most slicers are free.

What is a slicer? This is a program for preparing a digital model for printing. Models for 3D printing are usually distributed in STL files. To turn an STL file into G-code (a language that a 3D printer understands), a slicer program is required. It is called a slicer because it cuts (to slice - English) a 3D model into many flat two-dimensional layers, from which a 3D printer will add a physical object.

Which slicer should I choose? In this article, we will tell you which slicer is best for 3D printing for each stage of your work. Which one is better for preparing a 3D model for printing? But what if you need to create a 3D model from scratch? And if you are only taking the first steps in 3D?

Don't be afraid: we've answered all of these questions, including the required skill level for each program and where you can download it. The great thing is that most of these programs are completely free and open source.
