Method and plant for recovery of a processed, powdered structural material in a plant for manufacturing a three-dimensional component by selective solidification of the structural material by a beam directed onto the structural material, in which, in a construction station which includes a process chamber, the component is manufactured on a substrate plate in a construction module by layered hardening of the structural material and/or in which, in an unpacking station which includes an unpacking chamber, the component manufactured in the construction module is removed from the construction module, and the processed, non-hardened structural material is removed from the component, in which the processed structural material is collected in a collecting device by a recovery device and provided for further feeding into the process chamber for manufacturing further components, wherein the recovery device includes at least one cartridge filled with the processed structural material collected in the application device.

A system for forming a product with different size particles is disclosed. The system comprises at least one print head region configured to retain a first group of print heads configurable to additively print at least a first portion of the product with a first material and a second group of print heads configurable to additively print at least a second portion of the product with a second material. The described system may also comprise a processor configured to regulate the first group of print heads and the second group of print heads to distribute the first material and the second material. A method of making an object by ink jet printing using the disclosed system is also disclosed.

The present invention relates to a medical implant for cartilage and/or bone repair at an articulating surface of a joint. The implant comprises a contoured implant body and at least one extending post. The implant body has an articulating surface configured to face the articulating part of the joint and a bone contact surface configured to face the bone structure of a joint, where the said articulating and bone contact surfaces face mutually opposite directions and said bone contact surface is provided with the extending post. A cartilage contact surface connects the articulating and the bone contact surfaces and is configured to contact the cartilage surrounding the implant body in a joint. The articulating surface has a layer that consists of titanium nitride (TiN) as the wear-resistant material. The cartilage contact surface has a coating that substantially consists of a material having chondrointegration properties.

A laser treatment system and method for imparting beneficial residual stresses into a desired part during production thereof by a Selective Laser Sintering or Melting (SLS/SLM) process, the method including repeatedly subjecting the part to an in-situ Laser Shock Peening (LSP) treatment during the SLS/SLM process. The in-situ LSP treatment includes selectively bringing an LSP module in contact with a surface of the part during the SLS/SLM process, and subjecting the LSP module to the action of a first laser beam to impart beneficial residual stresses into the part. The LSP module is movable between a building chamber where the part is being produced for the purpose of carrying out the in-situ LSP treatment, and a separate storage chamber when the LSP module is not used for the purpose of carrying out the in-situ LSP treatment. The invention is also implementable in a corresponding additive manufacturing system and method.
