Cura vs Simplify3D: Which One Better For You?

When you talk to your 3D-printing-enthusiast friend about slicing up the fruits, he or she may not perceive it quite the way you think!

That is because “slicing” has an entirely different definition in the world of 3D printing.

Cura vs Simplify3D

Here it stands for slicing up your original 3D model file into many fine layers. This converted file called g-code carries the language your 3D printer will understand. So it will start implementing each layer according to the g-code instructions and you will get to see the result within minutes!

Among the many slicing software tools available today, Cura and Simplify3D are two of the most popular options.

While they perform the same function, they do differ in a number of aspects. We will dig deep into those factors today comparing Cura vs Simplify3D.

So let’s see who slices it the best!

What is Cura?

Cura is a software application used in the slicing stage of 3D printing. It efficiently divides the given digital image or file into many layers or “slices”. This sliced version called g-code varies from printer to printer. Each of the slices is then implemented in sequence by the 3D printer.

The free software was made utilizing three programming languages namely C++, Python and QML to reach its maximum efficiency. It was originally developed by software engineer David Braam. However, now it is a product of Ultimaker – a manufacturer of 3D printers.

It rose to fame in 2013 and has gone through several upgrades since then. The latest stable release in this line has been the 4.3 version launched in September of 2019.

Currently, more than a million people on the planet use Cura to print about 1.4 million models every week!

Besides, the software has also garnered lots of praise from professionals and received several accolades since its inception.

The most renowned and reliable names in the 3D industry like PrinterChat, All3DP and G2 have included it among the best software choices. In the 2019 edition of 3D Printing Industry Awards held in London, it won the title of Software Tool of the Year.

You can make Cura work with any of the top three operating systems – Windows, Linux and macOS. The kind of files compatible with this software includes the typical image formats (JPG, PNG, GIF and BMP), as well as 3D formats like OBJ, STL, 3MF and X3D.
