What are the main platforms for 3D printing online communities and discussion groups?

Best of Facebook 3D printing groups.

Facebook

The 3D printing community is very active on Facebook. You can find hundreds of groups about 3D printing, from general discussion forums to more specialized groups (notably groups for specific 3D printer models or specific interests such as 3D printing drones). Indeed, if you own a 3D printer, you may find a Facebook group of users of this specific 3D printer, with whom you will be able to interact and share insights. There are also many regional Facebook groups (by country or even city).  3D scanning is a smaller topic than 3D printing on Facebook. You still can find some highly interesting 3D scanning groups with passionate members. As an example: 3D scanning of Cultural Heritage or 3D Scanning Junkies.

Note: our friends at 3DPrinterChat.com created a comprehensive list of 3D printing Facebook groups.
