Realistically it takes my 3D printer about 90 seconds to warm up and while it&#x27;s printing I can be doing other things.<p>I, too, love manual subtractive fabrication. But while the tools are not necessarily that expensive, they do take up far more space on the shop bench. While I&#x27;m temporarily an apartment dweller, I just don&#x27;t have the space to set up my lathe or a mill.<p>The technologies are perfectly complementary. For example, often I&#x27;ll 3D print something with undersized holes and then drill and tap them to size.
