Most flagship 3D modeling programs are either too expensive or require a steep learning curve, making it difficult for beginners and home users to turn their ideas into 3D prototypes and models.
Not everyone wants to spend hundreds of dollars on software they just need for occasional use or small projects.
Similarly, beginners also often don’t have the time and training required to master flagship 3D modeling software such as 3D Studio Max and Maya. The good news is that there are many 3D modeling programs that make it easier for beginners to turn their ideas into a model, while most of them are also free.
This post includes some of the best and most popular 3D modeling software that available for free (or at least available as a free trial).
What is 3D Modeling Software?
As the name suggests, a 3D modeling software allows developing an object in three dimensions. It’s a specialized software that develops a mathematical representation of objects, surfaces etc. in 3D and may also allow displaying such 3D models as a ‘normal’ 2D images.
The advancement in technology and more affordable hardware has made it possible for the masses to print their 3D models. A 3D model uses points in a 3D space and connects them by geometric entities like straight lines, triangles, curved surfaces and more to represent physical bodies.
The application of 3D models is only limited by our imagination as they can be used in almost any industry. For example, the medical industry uses them for illustrating organs in detail, while the entertainment industry creates characters and whole movie sequences using 3D modeling software.
Known as 3D rendering, most 3D modeling software support converting 3D models into 2D images, which is an important factor to consider while choosing a modeling software.
Although not among the most easy-to-use modeling software, Blender is one of the most popular free 3D modeling software based on an open-source technology.
It is free to use for almost any purpose, including 3D modeling, animation, rigging, rendering, motion tracking, game creation, compositing and video editing.
The software is backed by a strong community of users that includes studios and hobbyists. Blender is based on Cycles Render Engine that offers realistic CPU and GPU rendering, real-time viewport preview and support for VR rendering.
Blender also includes tools VFX professionals and animation artists need to complete their projects, including camera and object tracking, raw footage import, footage tracking, area masking, skeleton, auto skinning, custom bone shapes and sound synchronization. The viewpoint allows combining 2D and 3D and supports Onion Skinning.
Since the software is based on a flexible Python interface, users can customize it according to their individual requirements and change things such as colors, layouts and size.
Users can take advantage of hundreds of community-made addons that help getting stuff done in less time and with less effort. In a nutshell, rather than being a software for artists, Blender is more like an all-in-one solution that works great for advanced users. Blender is available for Windows, Mac OS, Linux and Steam.

Things to Consider When Choosing Software
Selecting the right kind of 3D modeling software is crucial in getting the desired results as there are many programs available, each aiming to serve different type of users.
Some are specialized tools developed for home designers, while others focus more on game graphics, film and animation. Thanks to the advanced and more affordable technology, 3D printing is now within reach of the masses.
But with so many options to choose from, it often becomes a daunting task to pick the software that works best according project-based requirements. This post includes beginner-friendly as well as 3D modeling software that focus more on advanced users.
Here are some of the important things you need to consider before selecting a modeling program:
- Are you looking for a software for artistic projects, engineering projects or both?
- Does it offer all the project-specific features required for successful completion of a project?
- Is it available for free, as a trial or as paid software?
- Does it offer a timeline editor?
- The supported file formats and formats in which you can export or print the models
- Is the software easy to use and learn?
- The supported platforms/Operating Systems and software requirements
- Hardware requirements
Parametric vs. Explicit modeling
Parametric modeling is mostly used by architects and engineers who are more interested in specific dimensions, while explicit modeling is commonly used by artists and industrial designers who want more flexibility. Explicit modeling makes it easier for users to make on-the-fly changes, which might not related to other defined geometry points.
Online vs. Offline Software
Online tools run in a web browser and are mostly suitable for casual users who are dealing with small projects. Offline or installable 3D modeling software are run from a local machine using its hardware resources.
Although casual users might get away with older hardware and integrated graphics cards, serious 3D modeling requires powerful and specialized hardware, especially GPUs such as NVidia’s Quadro or AMD’s FirePro/FireGL.
The more complex the modeling projects become, the more powerful hardware you’ll need otherwise you might have to wait for hours before the software completes tasks such as rendering. It’s better to ensure that the hardware meets at least the minimum requirement or you might alter run into performance issues.
A beginner-friendly software might not be the best option if you are looking for advanced options and vice versa. That’s why it makes more sense to compare what a software has to offer with your own requirements and see if it’s really the right solution.
