The 3D printing industry and community have been transforming at a rapid rate. As new processes are being developed regularly, it’s useful for experts and hobbyists to share their experiences to benefit the 3D printing ecosystem as a whole. Discussion in these online communities and forums is generally about:

  • Raw material selection: The choice of raw materials and its effect on the end result.
  • Process variables: There are so many settings to tweak, after all.
  • Optimization: Sometimes, it’s important to track lead time and cost savings. Generally, in 3D printing, the optimization can be done on the design side, process side, or raw materials side.
  • Standards and certification: As 3D printing is still in its nascent stages, there is a need for standardization in some applications. For instance, 3D printed implants should have to adhere to the standards of regulatory bodies so that they’re clinically approved.
  • Training & skill development: It’s always nice to learn from the experiences of others.
  • Networking: Valuable online connections can transform into mentorship and business opportunities.

A. RepRap Community

The abbreviation “RepRap” stands for replicating rapid prototyper. It started in 2005 in England as an initiative to develop a low-cost printer that could print most of its own components and thus could spread quickly.


  • It has two mailing lists, one each for RepRap users and RepRap developers.
  • Local user groups and makerspaces provide local hubs.

B. Ytec 3D’s forum

Ytec3D is a platform which showcases technical projects involving 3D printing. This forum was created by a mechanical engineer to share all the projects he does in 3D printing to inspire people.


  • Users need to register and log in to take part in the discussions.
  • The discussion board has two categories, one each for 3D printing and projects.

C. 3DPrintforums.com

A relatively engaged group useful for hobbyists who frequently buy and use machines.


  • Community forums contain news articles, important announcements, website links, and videos.
  • This forum has a separate section known as “Classifields” for buying and selling 3D printing hardware, software, and materials.
  • This group also has discussions for industrial printing solutions, DIY printers, and site support.
