Free 3d Cad Design Software – Every 3D print starts as a 3D model created in modeling software. Years ago, we had to spend money and time to acquire and learn modeling software. Today, there are many easy-to-use modeling software options, and many of them are free. This list includes some of the best options and categorized by price, with free options arranged alphabetically.
The list also shows if the program uses a solid model, a type of 3D model that almost always produces a “branched” or “watertight” model. A bifurcated model is a model where all the walls of the model have some thickness, which is necessary for 3D printing. Conversely, software using a polygonal model can produce zero-thick walls; This is good for creating computer graphics for games and movies but not so useful when printing 3D models. Manifold models can be created using polygon modeling software, requiring more steps and experience. All of the programs on this list can create 3D printable models, but every model that comes out of solid modeling software is 3D printable.
Free 3d Cad Design Software
In addition, we note the user skill level each program is designed for: beginners, hobbyists, advanced users, and professionals. In general, the easiest to use options are near the top and the strongest tend to be near the bottom, although there are a few outliers throughout. Most of these programs are free to try and there are free video tutorials available for everyone.

All of these tools revolve around making models for 3D printing. Some of them are very easy to use while others are only suitable for professional users with years of experience.
Shapr3D is great for professionals and hobbyists. It has an intuitive and innovative user interface that allows you to create models faster with the same level of accuracy.
Using their visualization feature, you will also be able to preview the model in augmented reality to ensure your print will be perfect in its intended location.
Shapr3D is available on iPad, Windows and Mac – and will keep your files in sync between them! I 100% recommend checking it out.
D Cnc Software
This is a browser-based 3D design application aimed at beginners. This program has an intuitive concept of building blocks, allowing you to develop models from several basic forms. Tinkercad is full of tutorials and guides to help beginners who want to get the designs they are looking for. It also allows you to share and export files easily.
With a library of millions of files, users can find the skins that suit them best and manipulate them as they wish. It also has direct integration with third-party printing services, allowing you to print and have your print delivered to your door with the push of a button. Even though it’s very simple, it’s a great way to learn about 3D modeling.
At its core, Blender covers many aspects of 3D creation, including modeling, animation, simulation, and more. This open source software has a steep learning curve and is ideal for users who feel ready to design complex 3D models. Check out our Blender Tutorial for our 3D Printing page.
Blender is actually a free 3D modeling software originally intended for 3D animation and rendering using polygonal modeling techniques. Despite its origins as artist software, it is considered very accessible. One of the interesting features of the program is the photorealistic option. This gives the model an air of realism that some freeware programs can achieve.

This open source software is an advanced solid modeling system with interactive geometry editing. It seems to be used by the US military to model weapons systems, which shows that it is quite reliable but also very advanced. BRL-CAD provides a high level of accuracy because it uses specific coordinates to manage geometric shapes.
It provides a large library of simple and complex shapes that users can apply in their own designs. It can take many forms and accumulate at leisure as well. The software is very expensive, but it was made open source years ago. It includes more than 400 tools in its arsenal. It also works at a good speed, especially considering how heavy it is.
This elegant and free CAD software is suitable for advanced professionals and hobbyists. The user interface is relatively simple and the program works quickly, which means an efficient design. You also have the ability to create a bill of materials that calculates the cost of printing a potential 3D design project.
DesignSpark Mechanical allows users to take advantage of the built-in library to mix their own graphics. Another feature that new users can benefit from is the drag feature that allows users to create a 3D model of a surface. It’s feature-rich for a free and beginner-friendly program.
Choosing The Best 3d Cad Software: A Comprehensive Guide
An open source 3D parametric modeling tool that allows you to design realistic objects of any size. Parametric components make modifying your design a piece of cake. Just go to the history of the form and change the parameters, and you will have a different form. As the name suggests, it is actually completely free. The advantage is that no device is locked behind a paywall, so you can change your model to your heart’s desire.
It’s not the best for professional purposes, but it’s a great training tool. Although they are basic options and design elements, they are worth trying if you are new and don’t want to invest in something before you dip your toe in the water.
OpenSCAD is a free program with many unique features and ways to create models. This program takes a software approach to 3D modeling, which makes it a unique addition to this list of 3D printing software tools. Instead of a traditional interactive modeling interface, the user writes code in a text file that describes the parameters of the 3D object. Once you enter the code, you can see the form you created by clicking the “Collect” button.
Another great feature of OpenSCAD is the ability to import 2D drawings and output as 3D. Metafile uses parts of graphics made in standard drawing programs and uses SXF files to do so. With a stronger focus on programming, OpenSCAD can attract some while alienating others. Regardless, it’s still a powerful tool.
Woodworking Design Apps
Wings3D is another open source polygon modeling tool. Although it’s free, it comes with a variety of networking tools and options. Tools like a mirror make symmetrical modeling of the breeze. Since it is a beginner program, it is very easy to use and the learning curve is quite flat. Features such as customizable hotkeys and an easy-to-use interface demonstrate its status as a suitable tool for beginners.
Despite its ease of use, it does not lack useful features such as flat cutting, crosscut, insertion, folding, sweeping, circular, and transparent, which makes it capable of some very impressive models. It also supports various file formats for import and export. Despite its simple and obvious appearance, it’s definitely worth a look if you’re just starting out.
3D Slash focuses on providing design software with a unique user interface and advanced features that are sufficient for use with a high level of accuracy. You can also create 3D logos and text with this software. 3D Slash is free to use and perfect for beginners, but there are a range of price packages that add features for co-op or commercial depending on the needs of the consumer. Additionally, the free version has limitations in terms of functionality, high resolution, and the colors you can apply. The easy to use block cut style interface for creating shapes makes it simple for anyone to use.
Even if you can’t find the creative spark to start a design from scratch, there are many files available for download that you can import and then cut into something new. New features like cursor mode which makes interior design easier is a nice addition. Apart from working in standard mode, it can also be used with VR headsets. While the combined pattern can be restrictive in terms of the range of shapes one can create and less pleasing to the eye, it is nevertheless effective and functional. Few programs go from concept to completion as quickly as 3D Slash.
