3D Printing focuses on the hobby and practice of creating physical objects through additive manufacturing processes. This subtopic may include discussions about printers and materials, design software, file preparation, troubleshooting, and the progression from simple prints to complex, functional, or artistic creations. It can also cover home projects, prototyping, customization, and the evolving capabilities of consumer and professional 3D printing technology.

It’s a space for people to share projects, exchange tips, and discuss techniques related to printing, modeling, and finishing. Participants may compare hardware and materials, showcase successful or failed prints, and explore how 3D printing enables creativity, problem-solving, and hands-on experimentation.
