Creating the best models requires the best tools. Also, what better option is there than to choose a modelling tool that’s available for free as well.
For all novices and professional designers, there exist a wide number of 3D modelling and rendering software that has their own strengths and uses. Finding software that fits all the requirements is never simple. And even if you luckily find software available for no price, it’ll take some time before the environment becomes familiar and comfortable to use.
So have a look at some of the finest options for 3D modelling that can be used for no price and can be learned with the right dedication.
TinkerCAD allows you to combine simple shapes much like what toddlers do. But it’s much more than that.

- By using basic modelling operations, TinkerCAD helps users to join the shapes and create intricate models.
- After mastering the platform, even new users can create masterful designs like Raspberry Pi cases in no time.
- It supports a number of file types including 123dx, 3ds, c4d, mb, obj, svg, stl and serves as a great starting point for new modellers can be used in home remodelling & renovation.
LibreCAD is an open source free 3D modelling software with basic, easy to use cases and features. It displays only 2D views(causing it to be a lightweight software) but can be adjusted to support 3D file types.

- It can display isometric views, and unlike other CAD platforms, the user interface isn’t too sluggish or tough to get around.
- LibreCAD’s UI is heavily uncluttered, allowing for easier navigation.
- Supported file types include dxf, dwg and many common extensions.
- It is available for all commonly used operating systems and comparision with 3D model and mesh.
3. 3D Slash
If you’ve ever played Minecraft and ever wondered about its potentials in modelling, then 3D Slash is the answer to that question. It is a free software serving with all types of 3D modeling where models are created using simple building-block concepts like those in Minecraft.

- Conventional features like extrusion, revolution or sweeps are not in-built, and the program instead uses a cuboid centred modelling with a solid block that can be subdivided into smaller blocks of identical size
- By working around the cuboid with tools such as hammer, trowel, chisel, pulpwood, and drill, the design is thus created.
- The software can also be used for importing and modifying existing 3D designs. By default, the tools will result in pixelated prints.
- It also has 3D desktop printer options along with STL options. Common file types include 3dslash, obj, stl etc.
SelfCAD packages the complete design-to-print workflow under one umbrella and is an excellent robust 3D modelling application. Users can create intricate designs and 3D printable objects.

- The sotware has an intuitive GUI with a level of simplicity that matches TinkerCAD. Users can upload even a flat image and work on it to create 3D models.
- It’s best ability happens to be a platform that allows for a simple transition to 3D printing of houses and cutting short the requirements for slicing and piping the g-code directly to your computer.
- A number of pre-installed RepRap 3D printers are available from a drop-down which expertly stores every detail, edge, mesh and design.
- All this is available from a web browser through the SelfCAD website.
SketchUp is mostly familiar among designers as being a tool for architectural landmarks crafted by Google Earth and not its 3D printing strengths. SketchUp is an excellent tool for visualisation and planning in a variety of industries such as interior design, urban planning, engineering, and modelling structures.

- Clean and tidy user-friendly interface with easy to use features.
- Simple 3D printable models can be created from scratch within the first few hours of learning due to a number of intuitive tools that allow for great navigation and sculpting.
- Available with a number of extensions such as Curviloft which can be used to model complex organic structures.
- Users utilise designs from drawing layout functionalities with surface renderings called “styles”.
- SketchUp does not support STL files straight from sources but has a “SketchUp STL” extension that can be used.

FreeCAD is a parametric free 3D modelling software used primarily to bring 3D designs to real-life. Parametric modelling allows users to easily modify 3D designs by going back into the model history and change its respective parameters.
- It is open-source and highly customizable with working scripts and extensions. Built to some extent on Python, it consists of many features for modelling.
- Plugins can be mounted to the core application easily and allows for users to employ Sketcher with constraint-solver that studies 2D shapes.
- FreeCAD also has a robot simulation to study robot movements, and a module dedicated to mechanical machining systems such as milling (CAM).
- The output is available as G-code. Working file extensions include step, iges, obj, stl, dxf, svg, dae, ifc, off, nastran, Fcstd.
Often referred to as the “Swiss Army Knife” for 3D modelling, Meshmixer is a fully equipped 3D modelling software with much emphasis on the mechanical aspects of the 3D designs.

- Meshmixer is designed to create meshes and models for 3D printing. The benchmark for its success is its use of solid prosthetics with mechanical parts.
- 3D scans are commonly used along with optimisation tools used in industrial grade programs. Designers and modellers can cut down on unwanted storage and space needs from other softwares and reduce printing costs significantly.
- The software also has features to systematically generate joints that connect various parts into one single device. The software also has tools that can repair models such as hollowing, scaling, grading and mesh simplification.
- It’s not exactly a beginner’s tool but is jam-packed with various modelling basics and dynamics that seamlessly immerse with the Autodesk® family of modelling softwares.
- The software is available for all major operating systems.
- Working file types include amf, mix, obj, off, stl and many others.
