Computer aided design software because is the ultimate tool for creating designs to print on a 3D printer, such as Wematter’s own Gravity SLS. Free options exist that allow users to quickly get started with 3D modeling and CAD tools. Today, there are plenty of different free programs to use. So many exist that choosing the right one can be difficult.
Wematter has compiled a list of some of the most popular free programs on the market today. Click on one of the images or titles to get started with each program. Subscribe to our newsletter for more information or read more about Wematter here.
Programs for 3D-design engineering
1. Autodesk Fusion 360
(Windows, Mac)
Autodesk Fusion 360 is the software that we recommend for creating job files for a 3D printer. It is free for entry-level, hobby-level, or student users when the program is not used commercially. If using the program commercially, the turnover must be less than 12,000 USD. Fusion 360 supports cloud-based file sharing, version control, and import/export of the most common CAD files.
2. Onshape
(Web browser)
Onshape is a cloud-based CAD system developed by SolidWorks creator Jon Hirschticks. It can be accessed via a web browser or on a purpose-built phone app. The system processes real-time data, which means that several modelers can simultaneously work on a design and see each other’s changes directly.
Programs for Free form modeling/sculpting
3. Autodesk TinkerCAD
(Web browser)
TinkerCAD is an effective modeling program for beginners. Entry-level users can create useful models that can be sliced for 3D printers.
4. Blender
(Windows, Mac, Linux)
Blender is an open-source free 3D modeling tool that has become incredibly popular in a short time. The program is used by both amateurs and professionals. Blender has a large community and many free resources to get started, but the program has a high learning curve.
5. FreeCAD
(Windows, Mac, Linux)
FreeCAD is an open-source free program for parametric 3D modeling. The complexity of parametric modeling requires requires users to have complete control over their model. This can make the application unsuitable for beginners. The program nevertheless works for beginner and advanced modelers.
6. OpenSCAD
(Windows, Mac, Linux)
OpenSCAD is a free program that is based on programming a model, then generating it like software generated by computer code. The resulting model grants users with knowledge of source code full control, so use OpenSCAD if you like programming!
7. 3DTin
(Web browser)
3DTin is a browser-based program for modeling not entirely unlike TinkerCAD. It is free so long as the user shares her or his designs under creative commons attributes. When the user creates a model, she or he can export it to standard formats such as .STL, OBJ or similar so you can print them in your 3D printer.
8. Sculptris
(Windows, Mac)
Sculptris is the best free program for modeling in digital clay. Users can unleash their artistic talents to create organic models with which to decorate their homes.
9. Autodesk Fusion 360
(iPhone, iPad)
Inventor is a well-known name within professional CAD circles, and Autodesk has made a downscaled version called Fusion 360. It contains many tools that you otherwise only find in professional parametric CAD programs. Apple users looking for a more ambitious program should try Fusion 360.
Programs for Architecture
10. SketchUp
(Web browser)
SketchUp is based on drawings and dimensions adapted for architects, designers, and engineers. The program is easy to use and contains a variety of ready-made models. Users can find Wematter’s guide for exporting files from SketchUp here.
