LILUG Meeting Presentation

In the admittedly unlikely event you happen to be near the left-center part of Long Island this evening, drop in on my DIY 3D Printing & the Makerbot Thing-O-Matic presentation for the Long Island Linux Users Group meeting and pick up a tchotchke!

Many thanks to LILUG for ruthlessly eliminating all my objections to leaving the Basement Laboratory…

    1. Next time, I’m a-gonna hold out for room-to-room teleportation: driving on Long Island puts me out of sorts under the best of conditions.

      The talk went off well, though, with only a few folks nodding off in the far corners of the auditorium. Nobody snored and I call that a win. [grin]

  1. Hi Ed.
    I was at the meeting this week and I thoroughly enjoyed your presentation. Given the amount of time and thought you’ve put into your Makerbot, I was wondering if you had done any research into the pilling seems to occur on some pieces. Going off my sample set – the single 12-sided rattle I picked up – there appears to be certain geometric regularity to the zits. Could this be caused by a hiccup in the feeder mechanism? If so, do you think it is a hardware or software issue?

    Thanks again.

    1. geometric regularity to the zits

      That dodecahedron was part of some high-speed printing tests and certainly fall under my “know the limits” rubric!

      It turns out that printing more than one object at a time (it’s from a set of 9) tends to mess up the outside layer: the blobs hanging on the outside come from the drool emitted as the nozzle moves from one object to the next. In order to get a “perfect” outside finish (well, as good as it can be), you must print one object at a time.

      I plan to turn on the Dimension plugin and see how much zittage it eliminates, but that’s waiting on the 0.4 mm nozzle. Now that I’m done with presentations, I can tear the printer apart…

      Glad you liked the talk; it was interesting from my side of the podium, too!
