We live in a great time, where we not only have affordable 3D printers, but also a number of great CAD programs available for free, so you can easily design anything you desire yourself. With so many available programs it can be hard to choose the right one though. This list should help you to find the right software that suits your needs. These programs are also all very popular in the community, so you won’t have any trouble finding guides and tutorials that can help you get started.

Tinkercad

Tinkercad is extremely popular, and that for good reason. It is browser-based with a simple, friendly interface that lets you get started right away, no matter your skill level. If you don’t have any experience with CAD programs, or just want to make a quick and simple part, you can’t go wrong here. It is also ideal for 3d printing, as the models are saved in STL format, and the editing all revolves around manipulating existing solid objects, leaving you with a model that won’t give you any errors when 3d printing.

Fusion 360

If your projects are more complex and you are looking for a CAD program that is fully loaded with every feature you could want, look no further than Fusion 360 from Autodesk. While normally Fusion is a paid program, there is a fully-featured free version for startups and hobbyists. Inside the program you get access to full parametric modeling, allowing you to create dynamic models that can be easily adapted for your specifications. When your model is completed, Fusion 360 allows you to export the model as an STL file, or send it directly to Meshmixer for further processing.

FreeCAD

If you are not a fan of being at the mercy of big cooperations, FreeCAD offers similar features as Fusion 360, in an open-source format. With parametric modeling and many different workspaces for any application, FreeCAD is a favorite of many as it gives you access to professional features completely free of charge. And if the base version isn’t enough for you, there are many extremely powerful plugins that extend the functionality even further.

SketchUp

SketchUp has been around for a while and is also quite popular, especially for architectural design. It is fairly straight forward to use and has many features for creating even quite complex shapes. SketchUp also features a marketplace where you can get many premade models and a large list of plugins. While not necessary for most people, there is also a paid pro version with even more features. So no matter if you want to 3d print a model for your house renovation or a phone stand, SketchUp has you covered.

Blender

Well known amongst 3d animators and many others, Blender can also be used for 3d printing. You do have to be careful however to create a manifold model, otherwise, your slicer won’t be able to recognize your shape. Once you keep that in mind though, Blender is a great option if you want to create more organic shapes, which is hard to achieve with the more geometrically oriented programs previously mentioned. There is also quite a steep learning curve with Blender, but there are thousands of guides and tutorials out there to help you.

The FLIR Si1-LD is an easy-to-use acoustic imaging camera for locating and quantifying pressurized leaks in compressed air systems. This lightweight, one-handed camera is designed to help maintenance, manufacturing, and engineering professionals identify air leaks faster than with traditional methods. Built with a carefully constructed array of MEMS microphones for high sensitivity, the Si1-LD produces a precise acoustic image that visually displays ultrasonic information, even in loud, industrial environments. The acoustic image is overlaid in real time on a digital image, allowing you to accurately pinpoint the source of the sound, with onboard analytics which quantify the losses being incurred. The Si1-LD features a plugin that enables you to import acoustic images to FLIR Thermal Studio suite for offline editing, analysis, and advanced report creation. Field analysis and reporting can also be done using the FLIR Acoustic Camera Viewer cloud service. Transferring of images can be managed via memory stick or USB data cable. Through a regular maintenance routine, the FLIR Si1-LD can help facilities reduce their environmental impact and save money on utility bills.
