Best Slicer Software 2019

Updated Dec 13, 2019 11152

In order to print a 3D object, you first need to create a mathematical description of the model and then this information needs to be be transferred to the printer. The objects should be divided into layers - translated into G-code - so the printer can recognise the description and print out the model. This is exactly what 3D slicers do: they slice objects into layers, which are then printed out as a 3D model. The slicer software creates the G-code, which reflects all of the printing parameters.

In many cases, the quality of 3D models depends even more on the slicer than on the 3D printer itself. For this reason there are quite a few different 3D slicers to choose from, both free and pricy. In this article you can learn about some slicer softwares, find links for downloading and informational videos.

At the end of the article you can take a peek at a 3D slicers overview, which will without doubt help you find the one program that will match your needs.

Now let’s take a look at the most popular 3D slicers.


3D slicers


Simplify3D supports most desktop 3D printers on the market, regardless of the number of extruders and other construction features. If you happen to have a printer that is not on the list, you can manually adapt the program.

It is possible to quickly and conveniently edit your 3D models in the program. This software offers a ton of settings that you can play around with: extruders, layer control, various infill methods, temperature and cooling settings, even G-code and scripts can be edited. 

There can be several “Processes”  in one single printing task - different models or parts of the models with varying settings, such as wall thickness or infilling. This feature allows users to print several different 3D models simultaneously.

Characteristics: Overall, Simplify3D is a highly advanced software for 3D printing that can satisfy all of your needs. This means that paying a little extra is completely worth it. 

  • OS: Windows, Mac OS.
