A method for manufacturing a custom wearable and/or implantable medical device, such as an orthosis (e.g., an ankle brace, etc.), a prosthesis or the like, includes use of scanning processes. A digital model of a surface may be applied to a digital device model to define a custom digital device model. The digital model and, thus, the custom digital device model may include one or more standard features. The custom digital device model may be used with an automated manufacturing process to make some or all of the custom wearable and/or implantable medical device. In some embodiments, additive manufacturing processes may be used to form a portion or all of the custom wearable and/or implantable medical device.

A powder bed machine including a distribution device, which is configured to be charged with process material. The powder bed machine has a residual powder tank within the manufacturing process, wherein the residual powder tank holds a surplus of the process material. The powder bed machine is positioned on feet and weighing cells are located in the feet.

The present invention provides a multi-material 3D object printing method and a print control apparatus. The multi-material 3D object printing method includes: a. randomly generating at least one group of area print data based on each group of area information of a target object, then correspondingly generating layer print data according to multiple groups of area information of each layer of the target object, and forming the multiple groups of layer print data into 3D object print data; b. performing layer-by-layer printing based on the 3D object print data; and c. stacking layer-by-layer printing products from the step b to form a 3D object. As disclosed, a texture of a 3D object generated by means of printing is homogeneous, thereby expanding the application scope of manufacturing a 3D object by using an inkjet printing technology, and implementing smooth transition between materials in different areas of a same 3D object.

A processing machine for processing a workpiece with a processing beam includes a nozzle changer and a protective enclosure. The nozzle change is for mounting nozzles on or demounting nozzles from a processing head of the processing machine. The nozzle changer has multiple nozzle holders for holding nozzles. The protective enclosure is configured to close off a working space for the processing of the workpiece with the processing beam from a working space surrounding area. The nozzle changer is movable between a nozzle changing position within the protective enclosure and a setup position outside the protective enclosure.
