The Best CAD Software for 3D Printing (for Hobbyists & Professionals)

Not all CAD software is created equal.

Some excel at technical modeling for applications in fields like engineering and architecture. Some are more geared towards artistic modeling. Others simplify the process of creating 3D models suitable for 3D printing.

This article will focus on the last category, bringing you recommendations for the best CAD software for 3D printing.

As always, we’ll cover most bases, offering a solution for everyone from the occasional hobbyist with little to no experience to the well-versed professional on the hunt for a program to ease the transition from a 3D digital model to physical print.

We also have an article on the best free CAD software for 3D printing, if you’re on a budget.

How Does CAD Software Work With 3D Printing?

CAD software gives you tools to create a 3D model from scratch that can then be processed, sliced, and sent to a 3D printer for printing.

It’s the starting point from which a fully formed 3D model emerges, a digital blank canvas that allows you to transform an idea or concept into a real-world 3D printed object.

On a more granular level, the best free CAD software for 3D printing allows you not just to create an object or model but export it to a file format, such as STL or OBJ, compatible with and ready for slicing.

3D slicing software then translates the model into a set of G-code instructions interpretable by a 3D printer.

The printer can then print a physical, real-world replica of the CAD software-created digital model.

Best CAD Software for 3D Printing Buyer’s Guide – Things To Consider

What You Plan On 3D Printing

Simply put, this is about complexity and choosing a CAD Software for 3D printing capable of bringing your ideas to life.

While valuable tools for beginners, programs like TinkerCAD can only help you create pretty rudimentary models due to their reasonably limited toolset.

On the other hand, when using professional programs like Fusion 360 and SolidWorks stacked with advanced features, you’re only ever hemmed in by your skillset, experience, and the quality of your modeling ideas rather than the software itself.

In other words, if you plan on creating and 3D printing intricate, feature-rich models, be sure to use advanced CAD software.

The more beginner-friendly options will serve you well if you’re simply testing the waters or only have a basic print in mind.

Your 3D Printer’s Quality and Type

Spending hours modeling a pristine 3D model only to find out your 3D printer isn’t up to the task is not an experience we recommend to anyone.

As such, it’s essential to be well aware of your printer’s capabilities and choose a CAD Software that matches your 3D printing needs.

This is especially important if your model includes overhangs, sharp outward angles, precise surface details, or requires support structures. All these add complexity to the printing process, and not all printers are up to the task.

The type of technology underpinning your printer matters, too.

While cheaper and better suited to larger prints, FDM printers often fail when it comes to printing small, high-detailed models. On the other hand, resin printers excel at doing just that, prized for their ability to pump out high-resolution prints with plenty of fine detail and texture.

Look at your printer’s resolution and minimum layer height to get an idea of what level of detail you can expect.

File and Slicer Compatibility

Consider what file types a particular CAD software for 3D printing supports, especially export formats.

These largely determine compatibility with slicing software. Working hours on a model only to find out the program can’t export to a supported format is something you want to avoid.

As a rule of thumb, opt for CAD software for 3D printing that includes STL exporting at the very least.

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.

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.

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.

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.

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.

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 10 3D Printing CAD

TOP 10 3D Printing CAD

The software you should use when designing 3D printing depends entirely on its nature. The complexity of your object will influence your final choice. In general, simulation software can be divided into two categories: CAD software and software for 3D modeling . In most cases, CAD software will be used to create industrial objects that integrate more or less complex mechanisms. 3D modeling software is preferred when you want more artistic and conceptual freedom - it has historically been used in the video game and animation sector. We will also cover 3D software for beginners.

But what is CAD software ( CAD )? The acronym stands for Computer Aided Design and suggests that it facilitates the generation, modification and optimization of a design for a room or a series of more or less complex pieces. CAD software can be very specific, whether it's industrial design, mechanics, architecture, or aeronautical engineering. Today we will focus on the CAD software that is used to model future 3D printed parts. Considering the many features that the software can have, we have divided them by level of knowledge - beginner, intermediate and professional.
