    摘要： The present disclosure provides zirconium powder particles comprising pure zirconium powder particles with an oxide layer ranging from 0.05 to 5 microns in thickness and/or zirconium alloy powder particles with an oxide layer ranging from 0.05 to 5 microns in thickness. In some embodiments, the zirconium powder particles may be spherical particles, the zirconium powder particles may range from 5 microns to 125 microns in diameter, and/or the zirconium powder particles may have a median particle size ranging from 25 to 70 microns in diameter. The present disclosure further provides methods of producing medical implants or medical implant components by a process that comprises selectively applying energy to such zirconium powder particles to build the medical implants or the medical implant components. In some embodiments, the methods comprise repeatedly forming a layer of zirconium powder particles and irradiating the layer of zirconium powder particles with an energy source.

    摘要： We describe a system for simulating process monitoring by a sensor system in an additive layer manufacturing, in particular selective laser melting, process used to solidify material from which a three-dimensional workpiece is to be produced, wherein the system comprises: a data input coupleable to a data output of the sensor system and configured to receive, from the sensor system, sensor data relating to the process monitored by the sensor system, wherein the data input is further configured to receive one or more input parameters (i) relating to the additive layer manufacturing process and/or (ii) associated with an additive layer manufacturing apparatus used for the additive layer manufacturing process and/or (iii) associated with the process monitoring and/or the sensor system; and a processing unit coupled to the data input and configured to generate, from the sensor data and the one or more input parameters, a model for simulating said process monitoring.
