What Can You Expect With Free CAD Software?

For CAD software to be free, something has to give. A lack of a price of entry comes with limitations, so it’s important to understand what you can do and can’t do, and what differences to expect between free CAD programs for 3D printing and paid professional software.

User Interface

One of the main differences is user interface and overall polish. Paid programs tend to offer a more intuitive and fleshed out interface than their free counterparts, which can often be fairly barebones, leaning more on functionality than delivering a flowing user experience.

Applications

Suitable applications, and the features that enable this, are also a major difference between free CAD programs for 3D printing and paid CAD programs. Paid software is geared towards professional applications such as design and engineering that need a comprehensive suite of features, while free programs tend to focus on a specific element of 3D modeling with little in the way of extras.

Trials of Paid Software

Then there’s also the murky middle ground of free versions of paid CAD software where you’ll find many of the more sophisticated features like CNC milling, extensive export file formats, advanced simulations, and cloud functionality removed.

What this means is that choosing free CAD software for you is about selecting a program that has the features you need, but also whether you can live without what it doesn’t offer. For general use, especially modeling for 3D printing, the best free CAD software will more than suffice, but if you’re looking to power more specialized applications, this is where spending money on a premium program bears fruits.

Best Free CAD Software For 3D Printing

Tinkercad is a free browser-based CAD program that offers one of the most straightforward and intuitive interfaces available that’s chiefly geared towards beginners and kids wanting to learn the basics of 3D modeling. It’s developed by the folks at Autodesk, the same company behind Fusion 360, AutoCAD, and Maya.

The modeling process is based on shaping and modeling basic shapes using a range of simple tools to create models. These can then be exported to STL then loaded into a slicer to prep for 3D printing. 

Alongside, Tinkercad comes with a comprehensive library of tutorials, lessons, and learner projects perfect for those dabbling in modeling for the first time.


Sketchup Free

A step up in complexity compared to Tinkercad, SketchUp Free is still one of the most user-friendly free CAD programs available. It marries a sleek user interface with a solid set of tools that you can use to create everything from basic shapes to complex parts for 3D printing. 

SketchUp comes sided by 3D Warehouse, a catalog of user-generated designs that you can use as a launch pad for your own designs. SketchUp offers imports in SKP, JPG, PNG file formats, while it can export to SKP, PNG, and STL.

SketchUp is also available in premium form, which gives you access to features unavailable in the free version – plugins, point cloud data generation, real-time visualizations, renders, and more. 

These tend to benefit specialized applications more than 3D printing, so for most the free version provides enough functionality to take an idea from concept to model to print.


3D Slash

Much like Tinkercad, 3D Slash aims to demystify the often complex process of 3D modeling and make it fun. Something Tinkercad pulls off with a simple interface, easy to understand and use tools, but they are sufficiently powerful to create precise 3D models ready for 3D printing. 

It’s no stretch to say that someone with zero modeling knowledge should find their bearings using 3DSlash in no time at all. It’s one of the best free 3D printing CAD software tools for beginners.

In practical terms, users work to carve a basic cube into the desired design using a set of tools (hammer, text, color, flip, add shapes, etc.) in a manner that draws inspiration from building games like Minecraft. 

Once completed, models can be exported to STL and OBJ file formats. 3DSlash is available in both a web browser version and downloadable desktop version.


Morphi

Morphi is an app-based, tablet-only CAD modeling software that, much like Tinkercad and 3DSlash, is a solid learning tool for beginners and even young learners. It features a streamlined, intuitive interface sided by a set of tools all usable with the taps and swipes we’ve all grown accustomed to in this day and age of smartphones and portable devices.

Morphi’s simplicity is sided by an impressive selection of features for what is an app aimed at usability – in-built animation, AR tools, 3D rendering, library of image/video textures and 3D models, and custom texture creator to name a few. 

You can create models by subtracting, adding, drawing, and editing shapes, with the option to draw in both 2D and 3D based on your needs. Morphi also offers a wealth of import and export options – OBJ, STL, FBX, GLTF, 3MF, and GLTF, with more on the way.

Though paid tiers are available, the free version features all the same tools, but models come out with a distinctive watermark.


Meshmixer

FreeCAD is one of the best free open source CAD software for 3D printing out there, not least because it’s free. It’s also a parametric modeler, which means users can modify a model’s geometry based on tweaking parameters – dimensions, constraints, elements, etc. 

This makes it a potent tool for everyone from home makers to professional designers to create precision models for a huge range of applications. 

Though not specifically geared to 3D printing, FreeCAD does ease the process of preparing models for printing with file export options that include OBJ and STL. 

While free, FreeCAD offers an array of advanced tools such as finite element analysis, CFD, BIM, and more, though these are unlikely to be useful for makers who’ll be more than satisfied with the program’s 2D and 3D modeling capabilities.


Onshape

Vectary is a bit of an oddity on our list in that it’s mainly geared towards creating artistic models, but still boasts advanced parametric modeling capabilities. It’s a welcome bridge between the two areas and means it has an interface that won’t overwhelm newcomers and resembles more artistic-leaning programs like Photoshop. 

It doesn’t have too many advanced features (not a bad thing for those looking for simple modeling capabilities), but should do the job for amateur makers looking to create good quality models. The free version is fairly generous with no limited free trial in sight, only capped by a 25 project max, but you can move past this by paying just under $100 a year, which makes it one of the best priced cheap CAD options out there.
