Feature Request to help print N95 Mask

Posted (edited) · Feature Request to help print N95 Mask

I am printing masks for the local hospital.  I modified the Montana mask (www.github.com/brianmichalk1/MontanaMask) to make it nestable.  I multiply them and arrange them vertically, leaving one layer width between masks.

 

The problem is not all of the break lines are uniform.  Some are better bonded, and some result in failed prints.  Is there a way to fast track this?

 

1) Select multiply.  Have a checkbox for "multiply vertical".

2) assuming the part was previously placed for printing, just offset the mask using the same X, Y, but Z is reduced until there is a collision with the mask below.

3) Increase the vertical gap to be the same as the specification for support gap.

 

Only one point touching the build plate needs to be tested assuming it's a plane.

    Are you sure that nesting them reduces printing time? Printing the required support material for separation also takes time, and it increases the risk of failures, which also cost time.

     

    If you would use two glass plates, and preheat one while the other is printing, so you can switch glasses immediately after completion, it might go faster? Might be worth comparing both?

    There is no support material printed.  The previous mask is used for supporting the upper mask.

     

    Even if it is slower, the gains are to be had in not having to service the printer.  I can sleep while the printer is working.

    I recently printed a bunch of nested road-cones, with the same concerns - you save a lot of man-hours by just stacking them.

     

    I'll often use an external program (like MS 3D Builder) to make a set of objects how I like, then import them. You could add a small cylinder (say, 2mm dia, 5 high or whatever your offset it. Then stacking them in some programs would be trivial. That break away peg would be all that connects them).

     

    Similarly, using the numerical input on the "move" command can make it easier to get a regular stack - and save a .3mf to capture it all once you have one that works.

     

     

    Note: github link doesn't work.

    This is what I was thinking, with 3 pyramid "masks" and each has a set of break away legs. It's not as straightforward as I was hoping for though it would work well in an advanced program.

    Printing the masks directly on top of each other works.  The snap apart pretty well.  It's just a tedious process to lay it out.  I'm thinking of the printer noobs that want to help.  They may only be able to accomplish simple tasks for printing.

    Probably the easiest thing would be to save several versions (STL's):

     

    5 masks, 0.2 layers

     

    10 masks, 0.15 layers

     

    etc.

     

    That would be pretty trivial to load. On Prusa's site you could even post pre-sliced code - though if someone can't slice, can they even check that the mask printed right?

    I think ability to slice is a minimum for any printer owner.

    I'd upload your plate, once worked out, as an STL.

      • Introducing Universal Cura Projects in the UltiMaker Cura 5.7 beta
        Strap in for the first Cura release of 2024! This 5.7 beta release brings new material profiles as well as cloud printing for Method series printers, and introduces a powerful new way of sharing print settings using printer-agnostic project files! Also, if you want to download the cute dinosaur card holder featured below, it was specially designed for this release and can be found on Thingiverse!

      • 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.
