This isn't the first time we've been asked where to start modeling in 3D; it's perhaps one of the most common questions from people outside this sector, and that's normal. That's why with this second entry, we want to clear up that big question of where to start modeling in 3D... The first 3D modeling programs emerged in the 1970s as a way to create computer-generated three-dimensional images. Since then, they have evolved significantly and have become indispensable tools for design, animation, video games, film, and 3D printing.
3D printing is a technology that enables the creation of physical objects from digital models by depositing successive layers of material. It is a form of additive manufacturing that offers many advantages, such as customization, cost reduction, and innovation.
To be able to 3D print, you need a 3D model representing the object you want to create. This model can be obtained in various ways, such as scanning a real object, downloading a file from the internet, or creating it from scratch using 3D modeling software.
3D modeling programs are applications that allow you to create and modify 3D models using operations such as extrusion, rotation, scaling, subdivision, etc. There are many types of programs to start 3D modeling, depending on the method they use to generate shapes, such as polygonal modeling, parametric modeling, sculpting modeling, or voxel-based modeling.
If you want to get started in this world, the best programs to begin 3D modeling applied to 3D printing, we recommend starting with some free programs that are easy to use and offer good results. Some of them are:
- Blender: It's one of the most popular and comprehensive programs for 3D modeling. It has a very intuitive interface and allows you to create polygonal, sculpting, and voxel-based models. Additionally, it features other functions such as animation, rendering, physics simulation, and game design. It's compatible with most 3D file formats and can be exported directly to a 3D printer. Here's the link to its website: https://www.blender.org
- Tinkercad: It's an online program that works directly from the web browser and is designed for beginners. It allows you to create parametric models from basic geometric shapes that can be combined, modified, and aligned. It has a library of predefined objects that can be used as a base or as a complement. It also supports importing and exporting files in STL format, which is the most common format for 3D printing. Here's the link to its website: https://www.tinkercad.com
- SketchUp: Another online program that can be used directly from the browser or downloaded onto your computer. It's focused on architectural and interior design, but it can also be used to create 3D models of any kind. It features a highly precise drawing tool and a wide variety of extensions that expand its capabilities. It can be exported to STL format with a free plugin. Here's the link to its website: https://www.sketchup.com/
These are just a few examples of free programs you can use to get started with 3D modeling applied to 3D printing. There are many more you can explore and try based on your preferences and needs. The important thing is to have fun and learn while creating your own 3D objects.
