If you want to learn 3D modeling, you probably think of those expensive commercial programs that cost thousands of bucks, and you might've heard of Blender too. Well, today I'm recommending that exact free software—Blender.
What is Blender, Simply Put
Blender is a completely free and open-source 3D modeling program. Actually, it's more accurate to call it a full 3D creation suite. It's got professional features that rival paid software, and whether it's 3D modeling, making animated shorts, or video effects, Blender gives you a one-stop solution. Millions of users around the world love it.
A Full-Featured 3D Creation Package
Blender isn't just for modeling—it supports a complete 3D production pipeline:
- Modeling: Tons of tools for polygon modeling, curve modeling, sculpting, you name it;
- Animation: Keyframe animation, rigging, character animation, the works;
- Rendering: Built-in powerful Cycles and EEVEE render engines;
- Physics Simulation: Fluid, smoke, cloth, and particle simulations;
- Compositing & Post-Production: Has a built-in node-based compositor;
- Video Editing: Even includes basic video editing tools.
Works on All Platforms
Blender runs on Windows, Linux, and Mac—the three major operating systems. You can work on whatever computer you're comfortable with, and project files are fully compatible across platforms. Super handy if you use Windows at work and Mac at home.
What I Actually Use Blender For
I've actually wanted to talk about this software for ages. A few years back when I first got into 3D printing, I was debating which modeling software to learn. I checked out FreeCAD, Fusion 360, and Blender, but Blender felt too professional and had a steep learning curve. I was mainly making functional parts for everyday fixes, and Blender isn't built for parametric modeling, so I never really used it. It wasn't until recently when I needed to split a mesh model for 3D printing that I finally gave it a try.
Splitting 3D Models for Printing
I've been 3D printing characters from Warcraft Arclight Rumble lately. After downloading the STL mesh models from the official site, you could technically print them directly and paint them. But for characters like the Warden with her cape and robes, you need to split the body and cape into separate pieces to paint them properly. Regular slicer software just can't do that kind of cut. So after searching online, I found a plugin for Blender that some developer made—it lets you easily split 3D print mesh files based on mesh surfaces. There are even detailed video tutorials online.
Since I'll probably need to split models often, I learned some Blender basics, downloaded the plugin, and boom—problem solved perfectly.
My Two Cents
Obviously, Blender is crazy powerful, and I'm just using one tiny feature—like using a sledgehammer to crack a nut. But that shows how flexible and powerful Blender is: even a super niche need gets its own plugin. Tons of gorgeous 3D animation videos on YouTube and Bilibili are made with Blender, like those 3D music ball videos I love, or those beautiful sheet music visual effects.
Lots of people also use Blender to create 3D scenes, character models, animations, even game development. If you want to make cool 3D effect videos, Blender is a fantastic choice. It's got a huge and active user community—millions of creators, developers, and enthusiasts. Newbies can get help on forums, find tutorials, and access tons of free learning resources.
Plus, Blender keeps adding innovative features like Geometry Nodes for procedural modeling and the EEVEE real-time renderer, staying on the cutting edge of 3D tech.
Things Beginners Should Know
A few heads-up for newbies:
- Steep Learning Curve: Blender has so many features and the interface is pretty complicated—it takes time to learn;
- 3D File Compatibility: Blender uses its own file format, so compatibility with other mainstream 3D software can be tricky;
- Not Ideal for Parametric Modeling: Blender isn't a professional CAD tool. You can do precise engineering models, but it's not the best tool for the job.
About Free and Open-Source
Blender is a free, open-source 3D creation project released under the GNU General Public License version 3. You can download and use it completely free, even for commercial projects—no licensing fees whatsoever.
