The best part of waking up…

The new nozzle has so far proven to be reliable enough to print some (relatively) large objects almost completely without supervision. Shown here is the hopper for a Lyman filament extruder. It started out on the night before a work day and went on through the night. The next morning I woke up to the image here.

There are kinks yet, yes. You might notice close to the end the printer missed a few steps. This makes it look like the top “teleported” a few millimeters to the left. Strangely enough, the printer still managed to span the rather impressive overhang and bridges that resulted. Besides the frame shift, the top part suffers no other defects. After the print I took a hacksaw and cut the piece where the frame shift occurred. I then welded the top piece back into the correct place with a soldering iron. The result still has a noticeable seam to it, but its air tight, sturdy, and functionally without flaw.

I highly suspect the ad hoc z axis played some role in the skipped that occurred. There’ll be more later on how I plan to address it. In brief, a post apocalyptic printer would be a short lived thing if it’s not able in the end to print out its own replacement parts. That feature by itself has the added benefit of printing out offspring, ensuring (with some caveats) that the technology not only survives but thrives. Its about time for my printer to have a baby…
