  THEY PATENTED LITERALLY JUST POURING PLASTIC IN A MOLD WTF

  It is depressing that patents are granted that are simply derivable from the concept stage. If your patent idea can be rederived by anyone asking the same question...

  I can't believe after all this time we're going to go right back to those stupid airbrush nozzles I thought we escaped from hahaha

  Maybe this can be a way to avoid doing purge towers, which is a huge wasting filament. Just inject the purging into a bunch of holes until the new filament is ready.

  when you presented the problem &quot;the nozzle can&apos;t fill a hole that is too deep&quot; my immediate intuition was to break the filling operation into parts by height and fill, say... 5mm deep at a time. Especially since at the start of the video you talked about how the future is in the software.<br>This way you won&apos;t need a custom nozzle and you won&apos;t need to limit the height of the cylinder you&apos;re trying to fill.

  This might be a good solution for those who can afford and use one of those multi-color filament printer that waste a lot of filament as a part of their color transitions from one colored filament to the next. &nbsp;I believe it&apos;s referred to as &quot;Pooping Filament.&quot;<br>Rather than wasting or pooping that filament, it could be used to reinforce their prints if those prints were the types that could benefit by this reinforcement technique.<br>For those of us who&apos;s budgets won&apos;t allow such high end printers, I think figuring out how modify their filament pens to reach down into the voids of our prints might work. &nbsp;Just put the printer in pause then use their modified filament pens to quickly fill in the voids needing reinforcement and resume the print again.

  This is a really cool technique. I’m sure if you used the brick-laying technique and filled every-other hole at different intervals, it would increase layer adhesion.<br><br>I really like the idea of having “lines” that are perpendicular to the XY plane, increasing layer adhesion

  Would be cool to see it with hexagon infill to better fill all the corner voids, then shift the infill walls every 5mm or so so you can use a stock nozzle. As a TIG welder by trade, I will swirl the electrode a bit as I taper off the power when stopping a weld to prevent a fish-eye bump. The same concept could be added when filling the holes, start in the middle, but as it gets closer to filling you gradually swirl the nozzle wider inside the hole to fill out the top to the edges as well as kind of ironing it flat instead of getting the &quot;Chocolate Chip&quot; point in the middle.

  I&apos;ve been using a sparse infill that has a matrix of flow holes that allow a liquid epoxy to fill it completely. &nbsp;Then I can sand off the outside and be left with a much strong product when i need something with incredible strength.

  <a href="https://www.youtube.com/watch?v=H7nrJRBAMOA&amp;t=410">6:50</a> Not sure if you were just doing that just to show it on camera, but you can use that little stick that comes out the back of the micrometer to measure the depth of stuff. Open the jaws a bunch then press the stick against the bottom of the thing you are measuring, push down until the micrometer hits the top of the thing you are measuring.

  Injecting resin into an infill sounds like a cool idea
