Marksa, Novosibirsk, 630073, Russian Federation Abstract The possibility of applying the fused deposition modeling of polymer material for the repair of various products is discussed in the paper. The problem of short service life and replacement of failed button clamps of foreign-made passenger elevators is described. The material, basic conditions and printing parameters, as well as the additive equipment used to produce the clamps are given. The preliminary analysis of failed clamps is carried out and the reasons for its low service life are identified. All dimensions necessary to construct a three-dimensional model are measured and calculated. The modified model of the clamp strengthened version with changes that do not affect the functionality of other elevator control panel parts is developed. The special support structures that take the form of alternating columnar segments and adapt the part for additive manufacturing are designed. The control program is configured and the set of strengthened clamps for four elevator shafts is manufactured using the fused deposition modeling method.
