It's amazing what 3D printers can handle! But let's put things to the test with an umbrella that folds and extends with all sorts of complicated linkages, sliding components and folding bits, all of which prints assembled, without supports, and is ready to go, right off the print bed!

Now, how much torture is involved in printing this? It's actually not that bad. The toughest thing by far is making sure your bed adhesion is up to the task, though the Torture Brolly has been refined through many, many iterations to be as friendly to bed adhesion as possible (well, in relative terms, at least!). All the angles are nice and civilised, and the tolerances on all those moving parts are quite generous. However, if even one of those moving parts is compromised then the whole thing will fail to operate! So, while it's as printable as it can be it's still quite sensitive to print issues in general.
