Verfahren zum Erzeugen dreidimensionaler Körper oder Oberflächen aus organopolysiloxanhaltigen Ausgangsmaterialien durch Laser-Bestrahlung |
摘要 |
The invention concerns a method for producing three-dimensional moulded bodies, self-supporting and/or borne by a support or for creating structures on surfaces by local selective fixing of a material containing polysiloxane, said material ranging from fluid to pasty and organically modified, in a solution of said material, by polymerization with at least two photons. The organically modified polysiloxane is obtained by hydrolysis and at least partial condensation of a raw material containing or consisting of at least a silane of formula (I)R<sp>1</sp><sb>a</sb>R<sp>2</sp><sb>b</sb>SiX<sb>4-a-b</sb>, wherein: R<sp>1</sp>, identical or different, represents an organic group polymerisable by polymerisation with at least two photons; R<sp>2</sp>, identical or different, represents an organic group non polymerisable by said method; X represents a group capable of being separated from silicium by hydrolysis; the index a is 1, 2 or 3, the index b is 0, 1 or 2 and a+b together represent 1, 2 or 3.
