The updated toolset of Blender 2.91 features improvements to cloth sculpting, boolean operations, mesh to volume and volume to mesh conversion, custom curve bevels, searchable UI panels and more. Combined with hundreds of bug fixes, Blender 2.91 is more polished and stable than ever. Price: Free Solid modeling: No Intended for: Amateurs and advanced users What makes it special: It's open source, feature-rich, and includes tools for sculpting, animation, simulation, rendering, motion tracking, and video editing. In essence, Blender covers many facets of 3D creation, including modeling, animation, and simulation amongst others.
List of Open source 3D CAD Software :
1. FreeCAD
FreeCAD is a free and open-source (under the LGPLv2+ license) general-purpose parametric 3D CAD modeler and a building information modeling (BIM) software with finite-element-method (FEM) support. FreeCAD is aimed directly at mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical engineering. FreeCAD can be used interactively, or its functionality can be accessed and extended using the Python programming language and is currently in a beta stage of development.
2. Blender
Blender is a professional, free and open-source 3D computer graphics software toolset used for creating animated films, visual effects, art, 3D printed models, interactive 3D applications and video games. Blender's features include 3D modeling, UV unwrapping, texturing, raster graphics editing, rigging and skinning, fluid and smoke simulation, particle simulation, soft body simulation, sculpting, animating, match moving, rendering, motion graphics, video editing and compositing. While current versions also feature an integrated game engine, the upcoming 2.8 release will remove it
3. OpenCAD
OpenSCAD is a free software application for creating solid 3D CAD (computer-aided design) objects. It is a script-only based modeller that uses its own description language; parts can be previewed, but it cannot be interactively selected or modified by mouse in the 3D view. An OpenSCAD script specifies geometric primitives (such as spheres, boxes, cylinders, etc.) and defines how they are modified and combined (for instance by intersection, difference, envelope combination and Minkowski sums) to render a 3D model. As such, the program does constructive solid geometry (CSG). OpenSCAD is available for Windows, Linux and OS X.
4. BRL-CAD
BRL-CAD is a cross-platform CAD tool that dates back to 1979, although it would take 25 years for the source code to be released under an open source license. In fact, BRL-CAD is so old that it has been credited with being the oldest source code repository of an application currently in active development.
Originally developed by Mike Muuss at the Army Research Laboratory, BRL-CAD is been used for decades by the United States military for modeling weapon systems, but it also has been used for much more everyday design tasks, from academic to industrial design to health applications.
5. LibreCAD
LibreCAD is another CAD program that is designed to work across Windows, Mac, and Linux alike. A fork of QCAD (mentioned below), LibreCAD has an interface that will look familiar to AutoCAD users, and by default it uses the AutoCAD DXF format for importing and saving, though it can use other formats as well. LibreCAD is 2D only, though, so it makes more sense if your intended use is a site plan or something similarly, err, flat.
LibreCAD is licensed under the GPL and you can find its complete source code on GitHub.
The Slic3r project has been under active and massive development. Make sure you get 1.3.0 now or try the development builds!
Free. For macOS, Windows and Linux.Compatible with your printer too. RepRap (Prusa Mendel, MendelMax, Huxley, Tantillus..), Ultimaker, Makerbot, Lulzbot AO-100, TAZ, MakerGear M2, Rostock, Mach3, Bukobot and lots more. And even DLP printers.
Fast G-code generation is fast. Don't wait hours for slicing that detailed model. Slic3r is about 100x faster than Skeinforge. Five scary nights 3. It also uses multithreading for parallel computation.
Lots of input/output formats. Slic3r reads STL, AMF and OBJ files while it can output G-code and SVG files.
Do you like the graphical interface or command line? All the features of the user-friendly interface are also available from command line. This allows to integrate Slic3r in your custom toolchain and batch operations as you like.
Open source, open development. Cricut design room. Slic3r is open source software, licenced under the AGPLv3 license. The development is centered on GitHub and the #slic3r IRC channel on FreeNode, where the community is highly involved in testing and providing ideas and feedback.
Dependencies? Nah. Slic3r is super-easy to run: download, double click and enjoy. No dependencies needed. Hassle-free. For MacOS X, Windows, Linux.
Print with dual multiple extruders. Print beautiful colored objects, or use your secondary extruder to build support material. Or put a larger nozzle on it and print a faster infill.
Use brim for the best adhesion. This unique feature improves built plate adhesion by generating a base flange around your objects that you can easily remove after printing.
Microlayering: save time, increase accuracy. You can choose to print a thicker infill to benefit from low layer heights on perimeters and still keep your print time within a reasonable amount.
Compose a plate but print one object at time. Use the built-in plating interface that allows to place objects with drag-and-drop, rotate and scale them, arrange everything as you like. The sequential printing feature allows to print one complete object at time in a single print job.
Cool cooling strategies. A very smart cooling logic will regulate your fan speed and print speed to ensure each layer has enough time to cool down before next one is laid on it.
Manage multiple printers, filaments and build styles. The configuration handling system was designed for people working with multiple machines and filaments: you can save configurations as presets for each category avoiding to multiply your saved configurations.
Enjoy support material. Automatic generation of support material for overhangs.
