Best CAD Software for 3D Printing – 2023 CAD Programs
At 3DSourced we’ve covered everything 3D printing and 3D since 2017. Our team has interviewed the most innovative 3D printing experts, tested and reviewed more than 20 of the most popular 3D printers and 3D scanners to give our honest recommendations, and written more than 500 3D printing guides over the last 5 years.
The best CAD software for 3D printing is going to depend on two main factors: the nature of your project, and your experience using CAD programs for 3D prints.
In this guide I’ll walk you through my experience with the most popular 3D printing CAD software, comparing them across functionality, price, and who they would suit best – so you can make a confident decision.
My top recommendation for creative and artistic applications is Blender, while FreeCAD and Fusion 360 are more focused on engineering and technical applications.
Both Blender and FreeCAD are free and open-source, but the $60 pricetag or Fusion360 still represents good value because it’s the most comprehensive and powerful software of the three.
For complete beginners, TinkerCAD does the best job of simplifying the process of creating 3D models. Rookies should start with this free, browser-based software.
We’ll also discuss professional picks like SolidWorks and CREO. They’re expensive – and way beyond the needs (and budget) of most users – but worth considering if you need best-in-clas quality.

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, CAD software for 3D printing also allows you to 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 Printers
Blender
- Price: Free, open-source
- Supported 3D Printing File Formats: STL, OBJ
- Operating System Support: Windows, macOS, Linux
Blender is an open-source CAD program that leans heavily towards the artistic side of computer-aided design. It’s one of the most expansive and feature-rich free modeling software for 3D printing.
The software features a potent trove of features and tools suited to creative applications, including modeling, simulation, animation, digital art, video editing, and much more.
Though not innately geared towards 3D printing, the relatively new 3D Print Toolbox and Mesh Analysis features take strides to make Blender a far more 3D printing-friendly program.
Here, the idea is to simplify and process the often very complex polygonal models made with Blender to achieve better 3D printer results.
These new features include a series of checks and fixes that refine and clean up any model for export with 3D printing in mind. These include checking scale and measurement, wall thickness, edges, overhang geometry, support positioning, and hollow areas.
Although not a new addition, Blender also offers export to a selection of the most popular 3D printing formats, including STL.
Aside from this, Blender features a full-fledged modeling and sculpting toolbox to create high-quality 3D models. If anything, Blender suffers from this versatility and comes sided by a hulking learning curve, which means beginners may be overwhelmed by what’s offered here.
FreeCAD
- Price: Free, open-source
- Supported File Formats: STL, OBJ
- Operating System Support: Windows, macOS, Linux
FreeCAD is a free CAD software best described as a Swiss Army knife for all kinds of 3D modeling.
It’s a parametric modeler, meaning every aspect of a model is updated when changing a single parameter, part, dimension, or rule. Despite FreeCAD’s drab interface, the program is a powerful design tool that lends itself well to 3D printing.
FreeCAD works based on Workbenches, or toolsets, with different functions.
In the case of 3D printing, the interesting ones are Part and Part Design, which have a range of sketching, constraint, and modeling functions to create 3D models based on a library of geometric shapes.
There’s also a Mesh Workbench, which contains analysis and repair tools to iron out any potential errors that could lead to a failed print.
From there, FreeCAD allows you to export your model to the STL format, among others, and send it to a slicer program to 3D print cad files.
Fusion 360
- Price: Limited free version (non-commercial license) or $60/month
- Supported 3D Printing File Formats: STL, OBJ
- Operating System Support: Windows, macOS

In essence, Fusion 360 covers every step from design to model and part preparation.
There’s a free limited non-commercial version available for hobbyists and personal use. Alternatively, you can pay $60/month for the full version, which throws in fully-featured CAM, CAE, and PCB tools along with collaboration features and access to an unlimited number of active projects.
SolidWorks
- Price: Limited free trial, $4,000/year
- Supported 3D Printing File Formats: STL
- Operating System Support: Windows, MacOS
SolidWorks is a professional-grade 3D printing CAD software launched way back in 1995.
Although it houses state-of-the-art modeling tools, SolidWorks is relatively easy to use and is often praised for its clean user interface and intuitive workflow.
SolidWorks allows you to adjust model settings in preparation for 3D printing.
These include resolution fine-tuning, tolerance deviations, and visualization tools to ensure a model won’t result in a failed print. You can export models to STL, ready for slicing.
SolidWorks costs a pretty penny at $4,000 a year for the most basic licenses, so it isn’t a viable choice for amateurs and hobbyists, who’d be better served with a less feature-rich but far more affordable alternative such as Fusion 360.
CREO
- Price: 30-day free trial, $2,000-$3,000/year
- Supported 3D Printing File Formats: STL
- Operating System Support: Windows, Linux

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.
