Best 3D Printer Slicer Software

When 3D printing, it's exciting to pick out a printer, search for 3D printer materials such as resin and filament, as well as scour the internet for 3D printable designs. However, arguably as important as snagging a 3D printer unit is selecting a 3D printer slicer. Learn all about which 3D printer slicer programs to use, from what is a 3D printer slicer, to the best 3D printer slicer software you can download!

What is a 3D Printer Software Option and How do 3D Printer Slicers Work?

Especially if you're new to 3D printing, you're probably wondering what a 3D printer slicer is. 3D printer slicing software is a program that allows you to prepare 3D printable file. For most filament 3D printers, this means converting an STL file into a g-code file which provides commads that a printer understands. But this could be taking an OBJ file and converting that to g-code, cbddlp, or another format depending on what printer you're using.

The process of using 3D printer slicer programs is pretty easy. Simply fire up your slicer for 3D printing, load up a file, STL, OBJ, or otherwise. Then, proceed to make any necessary alterations such as rotating your 3D printable model, scaling up or down, and a bevy or other options. When you're finished, go ahead and slice it, then save the resulting file for printing. Often, 3D printers come bundled with 3D printer slicer software. My Elegoo Neptune came with an Elegoo-branded 3D printer slicer Cura version, while my Elegoo Mars resin printer provided ChiTuBox instead. 

1. Cura Slicer - Best 3D Printer Slicer Overall

The mobile version isn't a full-blown slicer, but works well enough. Its desktop component is a fantastic alternative that is well worth using. 

5. PrusaSlicer - Best Slicer for Both SLA/DLP and FDM Printers

While Prusa makes some of the best 3D printers money can buy, its slicer too ranks among the best 3D printer slicer programs available. The aptly-named PrusaSlicer formerly was dubbed Slic3r Prusa Edition. PrusaSlicer boasts compatibility with both SLA/DLP and FDM printers for a variety of options. Despite the Prusa in its name, PrusaSlicer is completely free and open-source with Linux, macOS, and Windows clients. 

6. MakerBot Print

Just as Prusa provides its own slicer, so too does MakerBot offer a slicer. Tailored for MakerBot printers, MakerBot Print is neat in its automatic slicing settings feature. It's capable of arranging across multiple build plates, printing Thingiverse objects straight from the MakerBot Print slicer, and a range of other functionality including remote printer management and monitoring. Unfortunately, it's only for MakerBot printers, but it's nonetheless a superb pick. Disappointingly, MakerBot Print is Windows and macOS only, no Linux support. 

7. Simplify3D - Best 3D Printer for Chromebooks

Chromebooks and Chrome OS devices are fantastic in their ability to present alternatives to macOS, Linux, and Windows operating systems. Unfortunately, the majority of 3D printing slicers don't tout Chromebook support. Yet for workarounds do bring 3D printer slicer for Chromebook compatibility. There's a method for installing Simplify3D using Crostini on Chromebooks. Unfortunately, Simplify3D does cost money. It's $150 USD for use on two computers. But this excellent 3D printer slicer packs in unparalleled compatibility with virtually every 3D printer on the market.

There are tons of options for resin printing such as hollowing out prints and generating supports. Overall, it's the best resin 3D printer slicer on the market. The only downside is that it's not compatible with filament printers, and instead it's exclusively an SLA/DLP/LCD 3D printer slicer. 

Best 3D Printer Slicer Software Options - Which 3D Printer Slicer Program Should You Use?

There's no shortage of 3D printer slicers. Which slicer you should use somewhat boils down to what printer you're using. Often, the default slicer is an excellent choice. I highly recommend using OctoPrint for its suite of tools including not only a slicer but 3D printer control, management, and monitoring plugins. Cura is a great pick as well. For resin printing, I'm pretty partial to ChiTuBox. What host PC you're using also dictates which slicer you can use. Thankfully, the majority of slicers are cross-platform. But Chromebook users might need either an in-browser slicer, or to follow a workaround for installing a slicer locally.
