What topics can I ask about here?

Please look around to see if your question has been asked before. It’s also OK to ask and answer your own question.

If your question is not specifically on-topic for 3D Printing Stack Exchange, it may be on topic for another Stack Exchange site. If no site currently exists that will accept your question, you may commit to or propose a new site at Area 51, the place where new Stack Exchange communities are democratically created.

(The following topics are merely suggestions, topics are not necessarily limited to the following and all topics are subject to community discretion)

  • Troubleshooting. Questions involving systematic analysis of a faulty system. Systems that may be related to 3D Printing:
    • Control Systems
    • Hardware (Mechanical or Electrical)
    • Software
    • Material
  • Repair/Maintenance. Questions requesting proper procedures for repairing or performing maintenance on 3D Printers.
  • Best Practices. Questions involving the identification or outlining of common procedures.
  • Technology. Questions requesting an explanation of how a particular 3D printing technology may work (Within appropriate bounds).
  • Material. Questions regarding technical specifications of 3D printable materials. This includes:
    • Proper use of a material in a given situation.
    • Identifying the proper material for a given situation
    • Standard printing preparation.
    • Material capabilities (Only related to 3D printed materials).
  • Capabilities. Questions verifying the capabilities of various 3D printing technologies for a particular style of object. For example, Is it possible to print a ball inside of another ball? (Yes, it's a simple question, but not everyone knows the answer. That's why they're asking the question.
  • Services. Questions requesting details about related 3D printing services.
  • Part Design. Questions related to optimizing 3D designs for machining.
