TLDR; The Best Ender 3 Software

Ender 3 Software – Slicers

If there’s one 3D printing program you can’t do without, it’s a slicer. It allows you to transform raw model data into the movement and extrusion instructions needed for the Ender 3 to print a real-world, physical replica. In other words, taking you from an STL to a G-Code file that the Ender 3 can interpret and use to create a print.

Here are our picks for the options for the Ender 3, all of them free and accessible, whatever your current 3D printing experience level.

No slicer software boasts quite the same popularity as Ultimaker’s Cura.

Much of this is down to the software being free and open-source, but a rich array of features and an ordered, intuitive interface play a part in why many Ender 3 owners point to Cura as their slicer of choice.

Given that Cura offers pre-set profile and setting configurations for the Ender 3 and Pro, it provides the opportunity to print without any initial tinkering.

Beyond these, over 200 individual settings are laid out in easily scannable categories to fine-tune the Ender 3’s printing performance further.

Cura also pulls off the impressive feat of being suitable for beginners and advanced users alike.

How deep you delve into the intricacies of the slicing process is up to you, with an integrated marketplace at hand to bolster Cura’s toolset with additional features like custom supports or CAD integration should you need them.

Creality Slicer

The Creality Slicer for Ender 3

A retooled and customized version of Cura, Creality Slicer is, to no one’s surprise, Creality’s in-house developed slicer.

The core appeal is that the Ender 3 comes with a microSD card loaded with Creality Slicer’s installation file, eliminating the need to hop on Google and download the requisite files to fire up the Ender 3 and print.

Furthermore, Creality Slicer is geared mainly for the manufacturer’s printer, with well-configured profiles for the Ender 3, Pro, V2, and the latest S1.

As these are tuned by the people most acquainted with the Ender 3’s quirks and intricacies, they tend to offer better results than pre-set configurations available for rival slicing software.

The big ‘but’ here is that Creality Slicer isn’t based on the most recent version of Cura and, therefore, is missing the most up-to-date features, like lightning infills and monotonic order settings.

The breadth of settings isn’t quite on par with Cura as a consequence, but Creality’s focus is on simplicity to not overwhelm first-timers, so the logic for this is sound. 

The interface is more or less identical, though. The only noticeable difference is an ever-present Creality logo tagged onto the UI’s top left and a jazzed-up color scheme.

PrusaSlicer

Though initially designed as a fork of Slic3r for Prusa printers, the free and open-source PrusaSlicer teams up well with the Ender 3.

Unsurprisingly for a program associated with Prusa, it’s user-friendly thanks to a clean and uncluttered interface but also powerful, offering users a range of sophisticated slicing settings and tools.

PrusaSlicer comes preloaded with well-tuned profiles for the Ender 3 and Pro along with the V2 and S1, something Cura doesn’t do.

Far from ballpark default settings, the profiles rival Creality Slicer for just how well they dial in the Ender 3’s performance.

An ideal pick if talk of retraction speeds and infill densities leaves you baffled. 

Prusa’s also includes an Ender 3 BL Touch profile, a nice touch for those who’ve made the upgrade, and over 150 auto-updating filament presets for the most popular brands out there.

Once you’ve nailed the jargon and have some printing experience under your belt, PrusaSlicer opens up to a wealth of customizable settings and tools. These include variable layer heights, an STL repair function, a paint-on seam tool, and in-depth print time analysis – to name a few.

Ender 3 Software – CAD Software

Have an exciting idea or concept you need to bring to life before sending it to the Ender 3 for printing? CAD software is a must-have, allowing you to model and design your very own objects and parts from scratch.

Fusion 360

A professional-grade CAD program for free? That’s precisely what Fusion 360 proposes if used for non-commercial, hobbyist ends or in an educational setting. 

Developed by AutoDesk, the developer behind the industry-standard AutoCAD, Fusion 360 is a comprehensive and powerful modeling tool that doesn’t pull any punches when it comes to features and functionality.

If you can dream it up, Fusion 360 can bring it to life.

Having all this at your fingertips may stir up worries of it being too daunting, but Fusion 360’s layout and interface won’t overwhelm or confuse you.

Stacks of free tutorials and more YouTube videos than you’d even need are at hand to help if anything isn’t clear.

Fusion 360 partners particularly well with the Ender 3 because it features a useful print simulation tool that will stress test the integrity of your model specifically for 3D printing.

It also bundles in slicer-like tools, like automatic orientation and support generation, to ease sending your part through a slicing program.

TinkerCAD

As easy on the eye as it is to model parts and objects for 3D printing, TinkerCAD is the beginner maker’s 3D modeling tool of choice.

It comes from the same developer behind Fusion 360 and AutoCAD, so it bundles in plenty of CAD pedigree and is a free, browser-based application to boot.

Inspired by the likes of Lego, TinkerCAD gives you access to a selection of basic solid geometric shapes that you can cut, combine, and sculpt into a 3D model, then add in texts, holes, and color as required.

It’s elegant in its simplicity, and despite its child-friendly appeal, can create all manner of parts ready for 3D printing.

TinkerCAD has a free library of starter projects and easily digested tutorials to help you get started if you’re struggling for inspiration.

You can also export models as STL files, ready to send for slicing, then on to the Ender 3 for printing.

Ender 3 Software – 3D Printer Controller Application

​​If you want more Ender 3 control and monitoring options beyond what the fiddly rotary knob and cramped touch screen offer, then you may want to consider a 3D printer controller application.
