Whether you are new to 3D design or at the professional level, there are several 3D modeling software packages to meet your needs and level of expertise. Having the correct 3D design software is essential to help create the perfect 3D model. Here is a guide to help you find 3D modeling software that is the best fit for you. These programs are categorized by those looking to create models for artistic purposes, and those interested in the engineering aspect of creating a 3D model. Let this guide help your decision, don't be afraid to try more than one.
Just Getting Started? Try this Free 3D Modeling Software:
If you are just starting and want a solid option to spark your design interests we recommend TinkerCAD. TinkerCAD is the best 3D modeling option for beginners. It is as easy as creating a account (https://www.tinkercad.com/) and follow the online tutorials. You can design basic parts quickly. There are limitations to the program but it is a great place to get started. Saving as an STL for 3D printing is fast and easy.
Purpose: Some great 3D modeling software programs are geared more towards artistic/sculpting OR while other 3D software platforms are intended for engineering purposes. Often it can be tough to achieve a design goal if you are using the incorrect 3D design software.
Cost: Ranges from Free to $5,000 +. Make sure you stay within your budget. For a beginner, most of the free 3D modeling software is the best for learning. Also, be warned: you get what you pay for in some cases free software can be awesome - but some are a bust.
Ease of use: Some design programs are easy to use and have great tutorials while others require some background in drafting or engineering which make it tougher (but not impossible) to pick up.
File Conversion: If you are looking to 3D print the parts you design make sure the files are robust when saved. 3D Printing uses the STL file type.
Definitions: Creating three-dimensional models using computer software can be referred to using many terms, but they all generally interchangeable: 3D modeling, 3D drawing, 3D design, 3D computer aided design (3D CAD). In conversation feel free to drop the "3D" and your friends will still understand.
Parametric vs. Explicit Modeling: If you are weighing these options you are already an advanced user, never the less it may be good to know that there are two distinct methods for 'defining' 3D geometry. The parametric approach is typically used by engineers and architects because the file contains more specific dimensions, relationships, and can include a design history. The explicit approach is typically used by artists and industrial designers because it can be more flexible. Explicit modeling allows changes to be made on the fly and small changes are not necessarily related to any other defined point of the geometry.
Breakdown by Category
The programs are listed from simplest to most complex.
If you are looking to create an artistic 3D model, here are a few of the best 3D modeling software programs that will get you headed in the right direction.
Blender (Free, Open Source - Linux, Mac, Windows) This 3d design software is typically used for creating animated films, visual effects, art, 3D printed models, interactive 3D applications and video games. This program is powerful, and can be quite difficult to learn. This software is handy to have for fixing and making simple changes to STL files.
ZBrush ($795 - Mac, Windows) This 3d modeling program is an all-in-one digital sculpting solution designed for those looking to create a work of art. This tool is used for creating high-resolution models for use in games, models, and animation. ZBrush is most known for being able to sculpt medium to high frequency details that were traditionally painted in bump maps.
Lightwave ($995 - Mac, Windows), 3DS MAX ($1470/year - Windows) and Maya ($3,454.00 - Mac, Windows, Linux), These professional 3D modeling and graphics packages are typically used for movies and TV. They are typically geared for the true 3D modeling professional. They include fast rendering engines that supports such advanced features as realistic reflection and refraction, radiosity, caustics, and render nodes. These packages have been used in dozens of large budget blockbuster films such as Avatar, Iron Man, and the upcoming Star Wars: The Force Awakens.
If you are more interested in the engineering aspect of creating a 3D model, we would suggest looking into these awesome 3D modeling Programs.
TinkerCAD (Free - Online) This easy-to-use tool runs in your web browser. It uses Boolean Modeling to make objects using shapes as building blocks. Combine or subtract the basic shapes to create more complex designs. Really one of the more mature and fantastic 3D modeling software platforms that is robust and easy to approach, even for kids and beginners.
123D Design (Free - Mac, Windows, iOS) This is a slimmed down version of Autodesk Inventor and part of a suite of apps that includes tools for scanning, sculpting, electronics, 2D design and more. This 3D modeling software is powerful yet easy to use.
Sketchup (Free basic version, $590 pro version - Mac, Windows) Originally made for architectural design, this software is easy to learn, but it will not provide all the tools that you will find with other software. File robustness can be hit or miss when it comes to 3D Printing.
FreeCAD (Free, Open Source - Linux, Mac, Windows) Parametric 3D modeling allows you to easily modify your design by going back into your model history and changing its parameters. Good program for converting STEP files to STL and with some training (see guides/videos) the price is right for some serious 3D modeling.
Rhino ($1,000 - Windows, Mac; 90 days free trial) This program is one of the most reliable programs for converting file types. Rhino’s open architecture allows users to also utilize Rhino as a development platform: a C++ SDK and a series of scripting methods (RhinoScript) allow programmers of any level of expertise to customize and automate Rhino and extend its capabilities.
If you are an experienced designer or just can't have anything less than the best of the best when it comes to the newest gadgets, these Professional programs are the answer.
Solidworks ($3,500 or more - Windows) and AutoDesk Inventor ($450/year - Windows) Professional grade 3D modeling/CAD software; both Inventor and Solidworks are typically used by professional design engineers. With that said, they are top of the line 3D design tools. If you do not have an Engineering background and are headed down this path, it may be worth investing in the Solidworks Bible.
