Above is a short video of the second prototype’s material deposition mechanism in action. In this demonstration a new layer of copper powder was added to the print in preparation for sintering the next 2D slice of the model.
In addition to the powder spreading shown above, we have already preformed multiple successful test prints on the machine. These prints have been of significantly higher quality than those produced by the first prototype, largely due to the inert atmosphere and the extensive software optimizations developed along side the physical prototype. At this time we are fine tuning laser parameters and movement profiles. Once we are satisfied with the quality of the parts produced we will certainly be posting another demonstration video.
