Discord and Reddit are the two of the best places for finding 3D printer purchase advice, technical assistance, and inspiration. The 3D printing Discords are more ideal for quick questions and images, while the 3D printing Reddit communities are ideal for detailed posts.
Purchase guides like ours for FDM printers & resin printers are great for side-by-side comparisons but if you want a personalized recommendation it will be best to visit Discord or Reddit.
Reddit Communities to join for 3D Printing
Reddit is the perfect place to get inspiration on models to print, get technical assistance, and help others. You can browse and share images and videos of FDM and Resin prints on various subreddits. If you need technical assistance with your FDM or Resin printer then you can create a detailed post - from what we have seen, questions usually get responses within the hour.

Both of these printers have better quality control, more capability, and a higher reliability - the price tags are higher but they are an ideal long-term choice.
Discord Servers to join for 3D Printing
From what we have noticed, the 3D printing discord servers are primarily used for getting technical assistance, general questions, and giveaways. You can easily post pictures with questions, and you can usually expect a response in less than 10 minutes. This is largely due to the instant messaging format, the fact that people have discord open on their desktop, and the discord app is easy to use on mobile devices.
