The Best 8 Free and Open Source 3D Modeling Software

3D models are crucial components of digital production whether we talk about animation, gaming, architecture, industrial design or 3D printing industry. With a minimum of fuss, you can realize your creative ideas if you have the right 3D modeling software.

From time to time, the beginners and home users find it difficult to turn the ideas into 3D prototypes and models as most 3D modeling programs are expensive and complicated to learn. People don’t prefer spending hundreds of dollars on software that are for small projects or occasional use.

Often beginners don’t have the time and training essential to master the 3D modeling software. Many 3D modeling programs are accessible for beginners to change their ideas into a model. If these models are free, then it will be great for beginners.

In this article, you will get acquainted with the best open source 3D modeling software that is free to use. But before that let’s discuss what 3D modeling software is and understand critical factors that will help you choose the best 3D modeling software.

What is 3D Modeling Software?

The 3D modeling software develops an object in three dimensions.It is considered as a specialized software that is capable of building up a mathematical representation of surfaces, objects and much more in 3D. It may display the 3D models as ‘normal’ 2D images. In a 3D space, a 3D model uses points and attaches it by geometric entities like straight lines, curved surfaces, and triangles to represent physical bodies.

The application of 3D models is used in almost any industry as our imagination only limits it. For example, the entertainment industry employs 3D modeling software to create characters and whole movie sequences. Most 3D modeling software encourages converting 3D models into 2D images. It is 3D rendering.

What is the criterion to select a modeling program?

Many modeling programs are available, and it is essential to choose the right kind of 3D modeling software as it serves up a different type of users. Some focus on game graphics, animation, and film while some are for home designers.3D printing is within reach of the heaps due to the advanced and more affordable technology.

To pick the best open source 3D Modeling Software following the requirement of the project is the daunting task.

Key factors to consider before deciding on a modeling program:

  • Requirements of the hardware
  • Easy to use and learn the software
  • Purpose of the software- artistic projects or engineering projects or both
  • Timeline editor is available or not
  • Supported file formats and formats in which models can be exported or printed
  • Supported operating systems and software requirement

Why is 3D Modeling important?

Around the world, the architects use 3D modeling to enjoy efficiency and aesthetic of their design. It provides architects and engineers with the required tools. The designs get transformed due to 3D modeling. Let’s discuss in what ways 3D modeling is essential:

  • Image Speaks- Image speaks a thousand words. You can give life to your favorite images using a 3D printer and can create unique personalized objects.
  • Realistic & Quick- 3D modeling facilitates a single picture of architectural services. The design gets vivid.  It becomes easy to take a virtual tour of the construction projects.
  • Simple re-modeling & Corrections- On the overall design you can effortlessly see the impact. Without much cost, you can finalize the design — the end construction shapes-up to the conceived output due to its accuracy.
  • Apt for marketing- It is more compelling and satisfying to experience a 3D model. For a more extended time, the vivid imagery lingers in the prospect’s mind. In the construction business, if the 3D model is used, then the approval rate gets quicker.
  • Blessing for interior designers- You can give a compelling view of the dream home or office building to the clients. With all the furniture, wall paints and designs you can plan the life-like model of the residential or commercial flat.
  • No language barrier- The 3D designs are instruction less and have no language barriers. Any human can understand 3D model naturally and can experience the virtual reality which it creates.
