With 3DTin, three-dimensional objects are constructed directly in the browser. The freeware offers various geometric figures, which can be put together to a total object. As a small tool, the website offers a variety of video tutorials, which are designed to help you get started with the design. This allows even beginners to quickly construct first objects. The models are built on a grid. The color of the background as well as the individual geometric objects are customizable. This means there is no limit to the imagination, the home, the car of the future or an imposing yacht, everything can be modeled according to your own ideas. It requires logging in via Google, Facebook, or Twitteraccount. There is a community where you can share and evaluate your works. The 3DTin software can be used with WebGL-enabled browsers, such as Firefox. After exporting as STL, OBJ, or DAE files, these models can be stored in the cloud.

Autodesk 123D is an intuitive 3D software for 3D volume modeling with a wide variety of versions. You can download your own support forums and design templates (furniture, vehicles, animals, tubes, cables, etc.) free of charge on the website, as well as numerous video tutorials for an easier introduction to the subject of 3D construction. In order to make full use of the program, you will need a period of training and some patience. In addition, the video instructions provide enough information to start with the construction of 3D models as quickly as possible.
Autodesk 123 Sculpt+
For Windows, Mac, iPad, iPhone and online
Autodesk 123D Sculpt + is designed specifically for designing 3D models on the iPad. The modeling is controlled by the finger on the iPad. You draw the basic structure, then structures and shapes are determined and finally you paint your sculpture or 3D object. In the app, it is possible to export the sculpture as an OBJ file or even to order it as a 3D-printed model. The software can be downloaded from Apple’s App Store for free.

Blokify was advertised as free 3D modeling app primarily for children, but now it is certain that adult users use the program to find an easy entry into the world of 3D design. After all, the surface is very easy to understand because it was conceived for children. It is a block-based 3D software, in which one interacts with the blocks by gesture. This allows you to tilt, rotate and manipulate the block via the touch screen.Blokify is a highly simplified modeling application that makes it possible to display objects in 3D CAD. Ideal for beginners and children!
Leopoly is one of the cloud-based modeling software versions. It makes it possible to create, save, and share 3D models online, via social networks such as Facebook or Twitter. The self-created models can be further processed by other persons. In the so-called “crowd sculpting”, a user with a simple virtual project starts to change this slightly and then presents it to a group of additional users who can also use this object for further processing. The freeware is suitable for beginners and beginners in 3D. In addition, the community supports the social networks in the use of the software and gives helpful tips.
For Windows, Mac and Linux
As the name suggests, Makehuman is a free software for making and printing 3D figures with a 3D printer. The freeware is particularly time-saving in that the human figures are already defined and can be enlarged, reduced or changed in a variety of ways. It is easy to determine the age, gender and origin. In the next step, all body parts of the virtual human being can be adapted in size and shape. Even on clothing can be customized, especially interesting in model building! Once you’ve finished creating your figure, you can either save it or export it to 3D printing.

With Morphi you get a pure 3D design and modeling app designed for Apple products. It has been developed exclusively for Apple devices and especially for touch screens. In the iTunes Store of Apple Morphi can be downloaded free of charge. It is easy to use in the application and allows you to create printable 3D models. With the app available on iTunes, users can easily apply 3D modeling tools such as Rotate, Zoom in, Zoom out, and grouping. After completing the Morphi-generated 3D model, it can be exported to a printable STL format.

Tinkercad is a free entry-level online app for designing simple models. There is even a wide range of templates (geometric figures, letters, cones, cubes, etc.) that can be used free of charge or you simply import already existing 2D and 3D designs. The 3D models can be exported in formats STL, OBJ, X3D, VRML or SVG or directly to a 3D printer. If you want, you can also upload the models in the 3D printing community Thingiverse and get tips and tricks to improve, or simply to get some praise.
