6 inch cube - 79 hour print!

Posted · 6 inch cube - 79 hour print!

Hello.

I am going to be test printing a wild bee house, it's a 6 inch cube with holes in it. I jut want to print fast and ugly for now to test the size and design. The low quality setting in Cura is telling me 79 hours, which cannot be right! In expert settings I'm on 0.2 layer height, 50mm second, 5% infill, 1.2 mm wall thickness. It goes to 89 hours!

Help. :)

    Amazing - Kisslicer time estimates are in the same ballpark - about 80 hours. Hard to see why it should take that long.

    I was able to get Kisslicer's estimate down to 48 hrs. by only doing Infill every third layer.

    It is a huge cube. I once printed a model that size, but totally hollow, no infill only 2 perimeters (.8mm walls) and 80mm print speed and it took 24 hours.

    So with infill, those very thick walls (1.2mm), and 50mm is kind of a slow print speed for an UM. Yes, it is probably

    spot on. You could speed it up slightly by reducing the wall thickness to .8mm. Increase print speed, increase infill speed higher. You could try pushing the layer height to upper .2's or low .3's with possibly a higher than usual temp to compensate for the larger amount of plastic.

    Forcing the printer to run faster is tricky, and can result in a half print. Just so you know.

    Larger prints like this need a larger nozzle size so you can do a much larger layer height.

    It is huge indeed. Just imagine in your head how much the print head has to move on every single layer of that print (all 810 of them). Just take the rings in the center for example, that's 64 retractions on those alone. Say it takes a second to do a retraction (I've never timed it so I have no idea how long it actually takes), that's an extra (64*810)/60/60 = 14+ hours on retractions alone. It adds up quick.

    Well Cura 14.01 does not think it is a 6 inch cube. If you rescale to 30% it fits onto the build plate - and I think my bed is a bit bigger than that on a UM1.

    Layer height .1 and print speed 20ms and infill 20% gives me 10.5 hours

    Please post pic but if you can print 10mm^3/sec (some can't) then you can do .2mm layer, 230C, 120mm/sec, no retraction .8mm walls. I can't imagine that would take more than 10 hours. Post picture please (in cad or in cura).

    I decided to be a bit more clever and spit the model. As this is only for a very alpha design test I don't need a solid part. I'll print many fronts and a single back, with a sliding join. First front is coming out out, 7 hours. Printing at 0.2, 60mm sec at 220.

    Here it is in CAD ,altered since then but gives you a rough idea.

    Good on you, the world needs more bees!

    Also, why not just make it a cylinder instead of a box? The important stuff is inside the cylinder anyways.

    I think you only need 2-5% infill for a model like this. Would save a lot of time.

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
