Abstract
Official abstract text for this publication.
A method for manufacturing a deflection member is disclosed. The method may include the steps of providing an additive manufacturing apparatus that includes at least one radiation source and a vat containing a photopolymer resin, providing a reinforcing member, contacting a surface of the reinforcing member with the photopolymer resin, and directing radiation from the at least one radiation source towards a surface of the reinforcing member to at least partially cure photopolymer resin in contact with the surface of the reinforcing member to create at least a portion of a lock-on layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a deflection member, the method comprising the steps of: a.) providing an additive manufacturing apparatus that comprises at least one radiation source and a vat containing a photopolymer resin; b.) providing a reinforcing member having a first surface and a second surface opposite the first surface; c.) contacting at least the second surface of the reinforcing member with the photopolymer resin; and d.) directing radiation from the at least one radiation source towards the first surface of the reinforcing member such that the radiation passes through the first surface of the reinforcing member to at least partially cure photopolymer resin in contact with the second surface of the reinforcing member to create at least a portion of a lock-on layer. 2. The method of claim 1 , wherein the additive manufacturing apparatus is an SLA apparatus or a CLIP apparatus. 3. The method of claim 1 , further comprising the steps of submerging the reinforcing member into the photopolymer resin and directing radiation from the at least one radiation source to at least partially cure photopolymer in contact with the first surface of the reinforcing member to create at least a portion of the lock-on layer. 4. The method of claim 3 , further comprising a step of directing radiation from the at least one radiation source to at least partially cure photopolymer in contact with the lock-on layer to create a build layer. 5. The method of claim 4 , further comprising the step of directing supplemental radiation to further cure at least one of the lock-on layer and the build layer. 6. The method of claim 1 , wherein the reinforcing member comprises foramina, the foramina each having at least one sidewall surface located between the first surface and the second surface of the reinforcing member. 7. The method of claim 6 , further comprising the steps of contacting the sidewall surfaces of at least some of the foramina with the photopolymer resin and directing radiation from the at least one radiation source to cure photopolymer resin in contact with the sidewall surfaces of at least some of the foramina to create at least a portion of the lock-on layer. 8. The method of claim 1 , wherein the reinforcing member comprises woven filaments and voids between the woven filaments, each void having at least four side surfaces located between the first surface and the second surface of the reinforcing member. 9. The method of claim 8 , further comprising the steps of contacting at least one of the side surfaces of at least some of the voids with the photopolymer resin and directing radiation from the at least one radiation source to cure photopolymer resin in contact with the at least one side surface to create at least a portion of the lock-on layer.
