Method for manufacturing an epilame mechanical part

A method for manufacturing a mechanical part (2) comprising a substrate (4) made of a first material capable of including an epilame product (6) reducing the surface tension of this substrate, the method comprising at least:

• a step (10) of depositing the epilame product (6) consisting of a second material on the substrate (4), said deposition being carried out in the form of a projection onto the substrate (4) of
• two collimated or localised beams (12A, 12B) of liquid material, at least one of the liquid materials containing the epilame product (6), the two liquid materials projected by the beams (12A, 12B) being selected so as to cause solidification when contacted with each other;
• and
• a step (11) of treating the second material to ensure the cohesion of the components on the substrate (4), said step (11) comprising a phase (28) of curing said second material comprising a localised sintering step obtained by irradiating said second material by means of a laser or a polymerisation by photo-crosslinking and/or by chemical crosslinking.
