Hyperlapse

Sup!

Now this is totally unrelated to 3D printing but since we do a lot of timelapse videos I though I would share this link.

 

It would be nice to have a clean continuous moving print head that just add layers after layers instead of blurred or scattered print heads.

    I contacted one of the member of the research team and he was kind enough to reply and suggest to look at "motion denoising" instead. Hyperlapse is really focused on camera stabilization and would not really change much in this kind of timelapse.

    I wonder if there are any implementation of this somewhere.

    I love timelapses one very cool stuff with what you suggest can be done with a classic timelapse if you're printing in Spiralize mode, like i did here:

    The timelapse here is quite slow (something like 12pics/sec). I'm shooting the pics with my RaspberryPi and Raspicam and i use a free software to make the video. I'll dig the internet to find something like what you showed would be cool to make the print look like it grows and have something less shaky

    Yes that was one of the reference video I sent to the research team :D

    Maybe the easiest way to do this is to shoot a regular video and to accelerate it.

    In my case in the video it happens that the pics where taken every 20 seconds (i think) and that it was a bit longer than the multiplier time for a layer, let's say the layer took 4.1 seconds to complete i'd take a pic every 5 layers but the head looks a bit further.

    yes that was how I did mine. Regular video and echo the frames.

     

    The result is different... but become blurry on the print it self. I could have masked the echo with some work but my pc is getting a bit old and doesn't handle a lot of processing anymore :(

    let's say the layer took 4.1 seconds to complete i'd take a pic every 5 layers but the head looks a bit further.

    that works only if your layers are all the same length.

    Yes that's why it's probably doable only in spiralize mode with vases...

    It's true that your video gets a bit blurry the result is different than a regular timelapse maybe it's too fast or indeed software tweaking could reduce the echo as you said

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
