| description | The invention includes a three-dimensional printing (3DP) machine that has at least one ultraviolet (UV) light source directed at powder or slurry being processed by the 3DP machine and/or directed at any of various surfaces or machine components, in a manner suitable to kill or damage microorganisms to a desired extent. The UV light sources may be either stationary or movable, and may be either pulsed or substantially continuous, and may operate in any desired sequence and timing with respect to other operations performed by the machine. The invention may include ultraviolet illumination in such a way as to interact with powder to sterilize or disinfect powder either while the powder is stationary or, alternatively, as powder is being moved from one place to another within the 3DP machine, or both. The invention also includes methods of performing three-dimensional printing using such illumination. The invention also includes the combination of other methods of sterilization or disinfection with the use of ultraviolet light. The invention also includes the use of ultraviolet light sources for a combination of polymerization/cross-linking in addition to sterilization/disinfection.
L'invention concerne une imprimante tridimensionnelle (3DP) comportant au moins une source de rayons ultraviolets (UV) dirigée vers une poudre ou une boue étant traitée par l'imprimante 3DP et/ou dirigée vers diverses surfaces ou composantes de la machine, de façon à éliminer ou endommager des micro-organismes dans une mesure souhaitée. Les sources de rayons ultraviolets peuvent être stationnaires ou mobiles, et peuvent être pulsées ou sensiblement continues, et actionnées dans n'importe quelle séquence souhaitée et synchronisée par rapport aux autres opérations réalisées par la machine. L'invention peut comprendre un éclairage ultraviolet qui interagit avec la poudre afin de la stériliser ou de la désinfecter soit lorsque la poudre est stationnaire, soit lorsqu'elle est déplacée d'un endroit à un autre dans la machine 3DP, ou les deux. L'invention concerne aussi des procédés de mise en oeuvre d'une imprimante tridimensionnelle au moyen de cet éclairage. Elle concerne enfin la combinaison d'autres procédés de stérilisation ou désinfection au moyen des rayons ultraviolets, ainsi que l'utilisation de sources de rayons ultraviolets afin de combiner la polymérisation/réticulation à la stérilisation/désinfection. |
