Having had a couple of months fine tuning the printhead, we've been able to dial in the precision and accuracy to a very high degree. At this point we estimate we're achieving about a 50um resolution with a high degree of repeatability. Here are some example outputs:
One application area we're investigating is producing micro features and meshes. To achieve very high resolution we've created a custom gcode generator that directly produces the printer commands using a specific set of geometric criteria. This has enabled us to produce some very fine meshes:
Here are some meshes with PCL:
We've also started playing with other types of materials, such as PCL, Ninjaflex, Nylon, and others. We made a slight modification to the print module to make it easier to print very flexible materials. So far this has worked fantastically well. Here's an early print of the Ninjaflex:
More to come!
