Top 20 Free 3D Printing & 3D Printing Software

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.

#1: Cura

For beginners who need a slicer to prepare STL files for 3D printing

Cura is the default slicer software for all Ultimaker 3D printers, but can be used with most others , including RepRap, Makerbot, Printrbot, Lulzbot and Witbox. The program is completely open source, its capabilities can be extended using plugins.

This program is very easy to use and allows you to manage the most important 3D printing settings through a clear interface. Start in Basic mode to quickly get up to speed and change print quality settings. If finer control is required, switch to Expert mode.

Cura can also be used to directly control the printer, but then the printer and computer must be connected to each other.

Download: Cura

Price: Free

Systems: PC, Mac, Linux

#2: CraftWare

3D printers by the Hungarian startup CraftUnique to support their CraftBot crowdfunding machine. However, the program works with other printers.

Like Cura, CraftWare allows you to switch from "Easy" to "Expert" mode, depending on how confident you feel. It's a colorful app that features a visual G-code visualization with each function represented by a different color. But the most outstanding feature is the individual support service. As far as we know, only the paid program Simplify3D has this.

Please note, however, that this program is still in beta, so bugs may occur.

#3: 123D Catch

-systems, smartphones and tablets, which allows you to convert images of objects into a 3D model. Pictures can be taken with a smartphone/tablet or digital camera.

You need many photos of an object from different angles - the more the better - after which they will be compiled into a 3D model.

123D Catch is more of a fun app than a professional 3D printing tool, but after some tambourine dancing, you can get good results, especially when paired with an STL editor like MeshLab or Meshmixer.

Price: Free

Systems: PC, Android, iOS, Windows Phone

#4: 3D Slash

and surprisingly simple, and refreshingly new. With 3D Slash, you can design 3D models using your dice skills.

You can start with a large block and, like a virtual sculptor, remove small cups from it with tools such as a hammer or drill, or start from empty space and build a model from cubes and other shapes. You can paint with flowers or use template pictures.

Other features worth mentioning are tools for creating logos and 3D text. The Logo Wizard imports an image and creates a 3D model, while the Text Wizard allows you to enter and format text, and then turn it into 3D.

Top Free 3D Printing Software in 2021 zero? What software is best for beginners? All these questions can be answered in our article. The applications presented in the review are completely free or have free versions for students, teachers and open source projects.

Why did we put this section before all the others? The answer is very simple. By knowing the whole 3D printing process, you can better understand how each software is involved in the preparation and printing of 3D parts.

If you have become a happy owner of a 3D printer, but have absolutely no idea what to do with it and how to get started, then this part of the article is for you.

Different programs are used to print 3D models:

  • 3D modeling/design/CAD software;
  • Software for editing, viewing and restoring STL files;
  • Slicing software;
  • 3D printer host.

Before starting work, you need to create a 3D model. To do this, you can use different programs for modeling. We wrote in detail about free versions of software for 3D modeling here.

A small life hack for beginners. If you are not ready to create a model on your own, you can choose and download the right one from the marketplaces. There are also free download links in the maker communities - sometimes the proposed 3D models can be not only interesting, but also useful.

Once a 3D model has been created, it must be converted to a printable format. For desktop 3D printers, this is the STL format. Some created or downloaded files have defects that lead to failures during printing. It is for editing STL files that there is special software that helps prepare the model for playback on the printer.

Slicer software helps to convert STL file into printer friendly G-code. The functionality of such programs allows you to split a 3D model into thousands of flat 2D layers, which will be sequentially reproduced on a printer.

Finally, the 3D printer host provides communication between the computer and the printer. It allows you to receive information for printing, as well as change the parameters of the device in real time via a PC. Often the Slicer and host are combined into one 3D printing software that is supplied by the printer manufacturer.

Dear readers of the 3DToday portal, we want to inform you that a new section "Knowledge Base" has been opened on our website of the LIDER-3D online store. In this section, we share owls, experience, settings and secrets of the world of additive technologies, go to the section at this link.

Examples of some already posted articles in the Knowledge Base section: Post-processing of models after 3D printing, 10 calibration models for your 3D printer, How and what 3D printers print, Printing with HIPS plastic, ABS printing settings, Recommendations for Resin Post-Processing HARZ Labs, Best Free 3D Modeling Software for Beginners.

Cura

One of the popular slicer software that comes with all Ultimaker printers. However, its functionality is suitable for use in conjunction with other 3D printers. Since this software is one of the most popular among makers, you can not waste time on profile settings - for most printers they can be found in the program itself.

The software is designed to change important print settings. Start with the “Recommended” mode to select improved quality settings for your printer and easily adapt to the program.

More precise control of all parameters is possible in the “Custom” user mode. By switching to this mode, you can manage more than 400 different settings.

Cura is not only a simple and intuitive slicer for home users. The software can be used as the main software for your printer, as well as integrated with CAD systems such as SolidWorks or Siemens NX.

The program is constantly updated and supplemented, which allows you to make 3D printing on your printer better.

PrusaSlicer

This software is based on Slic3r and, unlike the prototype, has gained great popularity among users. The main difference is a large list of customizable parameters and additional features that make the work more convenient.

An easy-to-use user interface, built-in support for Prusa printers, and multi-plastic settings make it easy to get started with your 3D printer. The slicer also allows you to place additional supports, work with different materials and use smooth features with variable layer height.

The PrusaSlicer can be used with both FDM and resin printers. Settings panels for users with different experience in 3D printing help to significantly improve the quality of finished models.

A great bonus for those who have worked with Slic3r before - PrusaSlicer supports most of the original features and accepts Slic3r configuration packages when importing profiles.

MatterControl 2.0

MatterControl is a CAD modeling software, slicer and simultaneous host for a 3D printer. With host functions, you can directly control printing by connecting the printer via USB. The program also allows you to cut STL files for export to an SD card for offline printing and, of course, create projects in a separate section of the CAD software.

Structured interface makes it easy to create models and prepare them for printing. A file browser and a library of geometric primitives make it easy to import data into print. Geometric figures can be used as supports, which helps to achieve high quality printing of complex details.

Advanced print settings and a user-friendly viewer make this software one of the best for comprehensive control of the 3D printing process. In addition to the host and slicer functions, MatterControl has design tools that allow you to design parts. The resulting 3D models are easy to export to a slicer and print. Thus, the program allows you to control the entire process - from creating a model to cutting it and sending it to print.

KISSlicer

The abbreviation of this application “Keep It Simple Slicer” can confuse inexperienced users. It's actually quite a complex 3D printing tool. Conflicting user reviews, however, allow us to conclude that the program is popular and has sufficient functionality to work with 3D printers.

The free version of the program is suitable for most users who work with printers with a single extruder. KISSlicer helps simplify certain aspects of slicing with Profile Wizards for printer-specific settings and Tuning Wizards for optimizing materials. The paid version of the program allows you to work with printers with 2 extruders.

Although the application settings are quite complex, it's worth the effort - the slicer allows you to have full control over the entire printing process.

Slic3r

This software is for open source slicers. Its main difference is advanced features that are not found in any other application.

Despite the fact that Slic3r releases almost no updates to its program, it is the base for many other open source software. For example, many programs use 3D honeycomb cavity filling, which is a special merit of the Slic3r developers.

In 2018, a new version of the software was released with new integrated functions. So, this version has new fill patterns, experimental support for SLA and DLP printers, 3MF format, and USB printing.

On the software website you can find a detailed manual that gives you an idea of ​​all the functions of Slic3r. A great bonus of the program is the direct integration with OctoPrint for printing at the touch of a button.
