Purge lines - Lemmy.World

What are purge lines for? Why can’t the slicers just leave them out? Can they be edited out manually in the code file?

3d modeling for printing - Lemmy.World

I’ve never used a 3d printer before but want to get one. I have a bit experience in blender but not too much. My question is: How do you model for a 3d print? For example, if I want to print a hollow cylinder, I go into blender, create cylinder and delete the side faces. If I print this, the walls will be pretty thin. Do I have to make them bigger manually? and if I do so (extrude and scale) does my slicer (cura) automatically fill in the solid part?

How are films recorded - Lemmy.World

I always hear people/actors/directors say, this tape or film is x meters long, it is this size, etc. do they really still use physical film? If so why aren’t they using terabytes of storage in a way more compact form?
