| Jan 21, 2015 at 23:36 | comment | added | Ryan Budney | Vasili: I suspect your question was closed for fairly trivial reasons. As written, it does not have the form of a proper MO question, in that you are asking an extremely open-ended question with little proper form, little criteria for a response being an answer. And by insisting on the connections being to algebraic topology (and your original algebraic topology tag) probably got the "wrong crowd" reading your question. If you edit it a little more, you could likely have it re-opened. | |

| Jan 21, 2015 at 18:33 | comment | added | Ryan Budney | I edited your question, putting in a comment to let people know what "4d printing" convention you are using. Feel free to revert my edits. Your algebraic topology tag wasn't quite appropriate, even though you were asking for connection. As far as I am aware, people take inspiration from objects in mathematics. In 3 and 4 dimensions, probably you want things like the Hopf fibration, minimal surfaces, incompressible surfaces, various types of fractals, knots, links, compressing surfaces, and so on... | |

created a tag more appropriate for the question, put in reference for 4d printing
|
| Jan 21, 2015 at 18:25 | comment | added | Tadashi | This feature article from AMS explores some mathematics used in 3D printing, but the involved mathematics is related to computational geometry, not algebraic topology. | |
| Jan 21, 2015 at 18:24 | comment | added | Henry Cohn | Thanks for the link! My first thought was that it was the analogue of 3d printing for people who live in $\mathbb{R}^4$. | |
| Jan 21, 2015 at 18:18 | comment | added | Yuichiro Fujiwara | @HenryCohn Presumably, 4D printing is 3D printing with programable shape transformation (i.e., the time axis gives the 4th dimension) like this: ted.com/talks/… | |

| Jan 21, 2015 at 17:42 | comment | added | Alex Degtyarev | Why do you insist on algebraic topology? How exactly did you come to this idea? | |

| Jan 21, 2015 at 17:29 | comment | added | Henry Cohn | The title refers to "printing" (what's 4d printing?), but the body of the question does not. What are you looking for? I don't think the question can be given a useful answer without more details. | |
