Software for 3D Printing - 3D Modeling Software/Slicers/3D Printer Hosts
An Overview Of The Best 3D Printing Software Tools
Every 3D print begins as a 3D model generated in a modeling program. Years ago, we had to spend lots of money and time to acquire and learn modeling software. Now, there are many easy-to-use modeling software options available, many of which are free. This list includes some of the best options and is sorted by price, with the free ones sorted alphabetically.
The list also indicates whether the software uses solid modeling, a type of 3D modeling that always generates models that are “manifold” or “water tight.” A manifold model is one in which all walls of the model have some thickness, which is necessary for 3D printing. By contrast, software that uses polygon modeling can generate walls that have zero thickness; that’s fine for creating computer graphics for games and movies but not useful when 3D printing the models. Manifold models can be created with polygon modeling software, it just takes more steps and experience. All the software in this list can create 3D printable models, but every model that comes out of solid modeling software is 3D printable.
Additionally, we’ve noted what skill-level of user each software is designed for: beginners, amateurs, advanced users, and professionals. In general, the easiest to use options are near the top and the most powerful options tend to be near the bottom, though there are some outliers found throughout. Most of these software can be tried for free and there are free tutorial videos available for all of them.

Introduction
What is 3D printing software?
There is a lot of software applications to the 3D printing process. From designing your parts to slicing them into G-code and even controlling a desktop 3D printer while it fabricates your parts, you will inevitably have to choose some 3D programs along the way.
What is slicer software?
A 3D printing slicer is a program converting your 3D model into a language your 3D printer will understand to manufacture your object. The 3D slicer will digitally cut your 3D model into flat layers; these are the layers your 3D printer will then print one by one. This slicer software will define the model and instruct the 3D printer to print it. A 3D printing slicer usually prepares the model by generating G-code, the programming language the 3D printer will understand. Slicer software is only helpful if you 3D print with your own FDM desktop 3D printer or resin 3D printer. When using a 3D printing service such as Sculpteo, no 3D printing slicer is needed!What are 3D printer hosts?
Some slicer software can also be 3D printer hosts, directly controlling your 3D printing machine. For this, you will need to connect your printer to your computer during the whole 3D printing process.What are STL editors and repair tools?
If you want to use additive manufacturing, you need one essential thing: a 3D file and, more precisely, an STL file. You can either design one yourself or find one online. But the files you find might not always correspond precisely to your needs. It might lack some features, have too many elements in it that you don’t need, or even be damaged. Thus, you will need to use an STL editor to fit your needs perfectly. You can use CAD software (Computer-Aided Design) or a mesh editing tool. They are made for modeling and objects represented by a 2D surface.What is 3D modeling software?
3D modeling software programs are designed to build 3D models of objects. Creating a 3D model is a mathematical representation of a three-dimensional object or shape. 3D models are used for various mediums, including video games, architecture, automotive, engineering, healthcare, etc. If you want to 3D print an object, you need to design it on a 3D modeling software – or buy an already-made 3D model.Slicers and 3D printer host

1. 3D modeling software
If you are ready to create from scratch, you will have to learn special 3D modeling software. Many of them, especially professional computer-aided design systems, can be expensive investments, but on the other hand, there are plenty of quite capable and at the same time free offers on the market.
Tinkercad
Tinkercad is a browser-based application from Autodesk that is great for no-experience users, even kids, because of its simplicity. In this program, 3D models are built on the basis of basic blocks - simple geometric shapes that are joined together and then "filed" to the finished look. You can also convert 2D vector images into 3D models. Of course, you have to pay for simplicity - in the case of Tinkercad, rather primitive functionality that makes it difficult to create truly complex models. But such a task is not worth it: having gained basic skills on Tinkercad, you can always move on to more complex and more capable programs on our list.
Official website
ZBrushCoreMini
ZBrushCoreMini is primarily a 3D sculpting tool, especially popular among those who create human and animal figures, computer game characters, comics, and the like. This software is mainly aimed at beginners and users with moderate experience, but at the same time, it is full of impressive features that make the work easier. For example, dynamic tessellation algorithms constantly analyze the surface of the working model and automatically add polygons so that detail is not violated.
ZbrushCoreMini is offered free of charge and is positioned as an entry-level program for learning and gradually moving to more capable and complex options - ZBrush and ZbrushCore.
Official website
3D Builder
This program was developed by Microsoft and was included with Windows 10 for some time, although now it needs to be downloaded and installed separately. 3D Builder allows you to edit models in STL, OBJ, and 3MF formats, as well as create models from scratch. In this regard, the program is quite primitive, but it is simple and understandable even for novice modelers.
One of the interesting features of 3D Builder is the ability to simplify meshes by reducing the number of polygons, file weight and processing time in the slicer - useful in cases where the original designer obviously went too far with polygons. Additionally, you can import models from the library and even use Kinect sensors to 3D scan and import models of physical objects.
Official website
SketchUp
SketchUp is a web application with a great combination of simplicity and functionality. The user-friendly interface is intuitive and greatly facilitates learning, and the set of tools is quite diverse even for advanced users - hence the wide popularity of this program.
The free version was formerly called SketchUp Make, but is now simply called SketchUp Free. It includes everything you need for 3D modeling for 3D printing, just don't forget to download the module for exporting STL files - it's also free. The kit comes with 10 GB of storage for projects in the cloud and access to the 3D Warehouse, a repository with open source user-generated content.
Official site
Fusion 360
Professional CAD developed by Autodesk and famous for its ease of use and advanced functionality. This includes parametric modeling and mesh analysis and load distribution tools, including through generative design with topological optimization. The program is great for those who are engaged in 3D printing of functional products, for example, for industrial applications.
Some versions of Fusion 360, such as hobby and student versions, are even available free of charge. FreeCAD FreeCAD The program relies on a parametric approach: at any point in history, you can scroll back and make changes to the parameters. The program even includes finite element analysis and a robotic system simulator.
Official site
Blender
One of the most popular 3D modeling programs, but quite difficult to master. Not the best choice for a novice designer, but a great tool for those who have already gotten their hands on simpler editors. Fortunately, the popularity of Blender has led to a huge number of guides, tutorials, and visual examples published by experienced users for beginner colleagues.
Developers are trying to make the program more convenient without sacrificing functionality: the interface has recently been updated, rendering has been improved, and 3D design and animation capabilities have been expanded. And yes, it's open source and freeware, so you don't risk anything.

2. Editing and repairing STL files
If you find an interesting 3D model on the Internet, this does not mean that it can be immediately sent to a 3D printer. Many models are created for completely different needs, such as animations or video games, and in principle are not intended for 3D printing. But there is a solution: before processing such models into G-code, they must first be repaired so that the slicer can do its job well. The following programs on our list will help you cope with the repair.
Meshmixer
Meshmixer is an advanced and free program from Autodesk that allows you to view and check 3D models for errors in polygonal meshes that can ruin 3D printing. If such problems are detected, the program can automatically repair meshes. One example of an application is finishing 3D scans to a state suitable for 3D printing.
Additional functionality includes mesh blending, 3D sculpting, surface writing, cavity creation, support branching, mesh smoothing, and more.
Official website
MeshLab
MeshLab is another open source program for editing polygonal meshes. MeshLab has the necessary tools for editing, checking, cleaning and converting meshes with the ability to combine meshes into one model and patch holes that can lead to incorrect processing of models into G-code.
Official website
3. Slicers
After receiving a 3D model, it must be converted into machine code - a series of commands understandable to CNC machines, including 3D printers. Slicers are responsible for this task - programs that accept digital models (usually in the form of files with STL, OBJ or 3MF extensions), analyze their structure, and then compile lists of actions for 3D printers, called G-code (Gcode). Such lists contain all the information necessary for the equipment: to what temperature to warm up the extruders and tables, whether to use airflow, along what trajectory and at what pace to lay the plastic.
Cura
Cura is a slicer from the Dutch company Ultimaker, designed primarily for proprietary 3D printers, but open source and compatible with most other FDM/FFF systems. The program is easily customizable with various plugins. Since this is a very popular program, the chances are that it already has a profile with optimal settings for your 3D printer. If not, then nothing prevents you from creating a profile manually or using profiles prepared by other users.
The program has several levels of difficulty depending on the level of training - basic, advanced, expert and complete. The higher the level, the more access to customizable options. At a basic level, the program takes the bulk of the work on itself, helping inexperienced users.
Cura is constantly being developed and improved through regular updates and is also offered free of charge, although a paid version of Cura Enterprise is available to professional users with licensed plug-ins from the Ultimaker Marketplace, technical support and additional security measures.
In addition to converting 3D models to G-code, Cura can also take on the role of a control program, but this will require a constant connection between the 3D printer and the computer throughout the 3D printing. Professionals appreciate another feature of Cura - seamless integration with professional computer-aided design systems such as SolidWorks and Siemens NX.
In general, Сura is suitable even for novice users, especially since a huge number of training videos and step-by-step guides are available for this program, both from developers and enthusiasts.
Official website
PrusaSlicer
3D printer manufacturer Prusa Research, under the leadership of the legendary Czech engineer Josef Prusa, whose designs are copied and refined around the world, has developed its own open source software based on the Slic3r slicer. PrusaSlicer quickly gained popularity as it not only retains the original program's extensive customizations, but also adds a number of useful features not found in Slic3r.
A redesigned interface, support for Original Prusa branded 3D printers, and profiles with settings to work with many common polymers are just some of the improvements. Additionally, algorithms for generating support structures have been improved, support for multimaterial 3D printing and the ability to dynamically adjust the layer thickness have been added.
PrusaSlicer can process models not only for FDM 3D printers, but also for stereolithographic systems printing with photopolymers. As with Cura, the user can select a difficulty level with appropriate access to fine-tuning.
Official website
ideaMaker
Raise3D's slicer is optimized for branded additive hardware in the same way that PrusaSlicer is optimized for Original Prusa 3D printers, and Cura is optimized for Ultimaker 3D printers, but this does not mean that it cannot be use with third party systems. The organization of workflows and the interface is somewhat more complicated than in Cura and PrusaSlicer, but on the other hand, ideaMaker allows you to set up individual layers and apply textures for product customization.
ideaMaker users can connect to the cloud platform and access hundreds of 3D printer profiles and materials created by other operators, or create their own library of settings.
Add the ability to customize support structures, split models for more efficient 3D printing of large parts, integrated mesh repair tools, and OctoPrint compatibility, and you have a flexible, versatile program to suit the needs of most 3D printers.
Official website
ChiTuBox Basic
This is a specialized slicer for those who use stereolithographic 3D printers that print with photopolymer resins. Most budget LCD masked stereolithography (MSLA) 3D printers rely on motherboards and firmware from ChiTu Systems, which also developed this software.
Users gain control over technology-specific parameters such as layer exposure time, as well as access to predefined profiles with settings for many popular 3D printers. The slicer takes into account such moments as the orientation of the model and the automatic construction of support structures with the possibility of manual optimization.
Official website
Lychee Slicer
A program from the independent Franco-Belgian team Mango 3D, not associated with 3D printer manufacturers, but with support for many popular stereolithographic 3D printers, including those from Elegoo, Anycubic, Phrozen and Creality.
One of the features of this program is the high level of automation. If you wish, you can simply click on the "magic" button (it's called Magic), and the slicer will do everything by itself: it will orient the model on the platform, generate supports, and so on. Although, here you are lucky: the results are not always optimal, but usually adequate for relatively simple models. Otherwise, everything can be configured manually.
The program is offered in free and paid versions. The functionality of the free version is slightly reduced, but it has everything you need.
Official site
Kiri:Moto
Browser solution for those who lack computing power. Kiri:Moto can prepare 3D models for both 3D printing and laser engraving or milling. The settings are somewhat more primitive than in locally installed slicers, but are sufficient for most users.
Official website
IceSL
IceSL is a combination software that combines slicing with 3D modeling. In the left window, you can edit 3D models using scripts in the Lua language, which makes it possible to perform parametric modeling. On the right side, the 3D printing settings are displayed. For beginners, pre-configured settings are available, while experienced users can take advantage of features such as specific adjustment of parameters for individual layers with automatic gradation of intermediate areas. For example, this allows you to gradually reduce or, conversely, increase the filling density of the product as it is built, or gradually change the thickness of the layers.
Official website
4. Control programs
Control programs are designed for exactly this - managing workflows during 3D printing. Although you can insert a G-code drive into almost any 3D printer and press the start button, this is not always convenient, especially when you have to work with several 3D printers at the same time, and even more so when you do it remotely. This is where control programs come to the rescue. In addition, some of them offer additional functionality, including slicing and even editing 3D models.
OctoPrint
A web-based appliance that requires connection to a 3D printer via a microcomputer such as a Raspberry Pi equipped with a Wi-Fi module. This system allows you to control 3D printers remotely. OctoPrint accepts G-code from almost any slicer and provides the ability to visualize - view files before and during 3D printing. Alternatively, STL files can be loaded and processed directly in OctoPrint.
OctoPrint not only provides all the necessary tools for remote management, but also allows you to track the work in progress using notifications via various instant messengers.
This is a completely free, open source program with many plug-ins created by enthusiasts and available on the official website.
Official website
MatterControl
MatterHackers offers its own control program, slicer and 3D editor in one package. MatterControl allows you to directly control and observe 3D printing, slice, export G-code to SD cards for offline printing, and even create 3D models from scratch. The 3D printer will need a Wi-Fi or USB connection to run MatterControl.
The interface is well structured: on the left side there is a file browser and a library of simple geometric shapes. Interestingly, these shapes can be dragged into the 3D model and used as support structures.
Basic functionality is available in the free basic version, advanced users can pay to upgrade to MatterControl Pro.
Official website
AstroPrint
AstroPrint is a cloud-based management platform that allows you to remotely monitor and control multiple 3D printers simultaneously, store files, convert 3D models to G-code, and track workflow statistics. The functionality ranges from basic in the free version to advanced with different levels of paid subscriptions.
The 3D printer will require a Wi-Fi module to fully work with AstroPrint. In conjunction with the Raspberry Pi, the system is similar in functionality to OctoPrint: you can process models and send the finished code to a 3D printer via a web interface without the need for additional software. Another plus is integration with popular repositories of 3D models Thingiverse and MyMiniFactory, as well as 3D editors 3D Slash and Leopoly.

5. Programs for visualizing G-code
What if you find an old file with a G-code, but you have no idea what it is and why - maybe garbage, or maybe an excellent, but long-forgotten model without a clear marking in the file name? The programs in this section will help you visualize the contents of such files.
UVTools
This program combines file browsing with layer editing and even model repair for stereolithographic 3D printing. The program can also be used as a plug-in for PrusaSlicer, adding support for third-party photopolymer 3D printers - although PrusaSlicer is open source, support for stereolithographic systems is still limited to branded equipment. At the same time, UVTools allows you to print calibration samples to check the exposure time and other parameters, which can be useful, for example, when working with new photopolymers that have not yet been tested.
Official website
WebPrinter
A simple browser tool for quick G-code preview, developed by the same team that created the IceSL slicer and 3D editor. The application works very simply: follow the link, upload the file with the G-code and see how the 3D printer will grow the model according to the commands provided. Unfortunately, the functionality is limited: for example, the application does not provide information about temperature settings. On the other hand, you can quickly figure out what kind of model is hidden in a file with an incomprehensible name.
Official website
Gcode Analyzer
An old but still very capable and popular G-code analysis web application. The 3D simulation doesn't work very well, but the 2D and G-code previews work great. In 2D mode, you can conveniently view individual layers, moving from layer to layer and following the construction path step by step using two sliders. G-code viewer displays a complete list of commands, allowing you to see what a particular line of code is doing.

Top 20 Free 3D Printing and 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 the best choice 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.
