infill modifier mesh gets printed first

Posted · infill modifier mesh gets printed first

I print my parts "lying down" due to strength requirements.  This places the top and bottom on the "left" and "right" (actual location varies due to part placement).  So, I use modifiers to achieve the additional solid thickness required at the real-world top and bottom (thicker than the walls).   However, Cura wants to print one of the modifiers (the part's real world bottom), an interior infill section, before the part's walls.  This causes some defects.  I'd like it to print the walls first, as usual, and then the modified infill sections as part of the infill, just with higher density than the rest of the part.  It does print the top modified infill as desired, after the walls.  Part of the difference may be due to the user specified Z seam alignment, as the bottom is located at the desired Z seam location, while the top is at the opposite end of the build plate.  To be clear, the current modifiers are the entire top and bottom 5mm of the part.  I haven't tried modifiers that are just the interior (minus the wall thickness), which I could do, but it's more of a modeling hassle.

 

For the modified sections, I use either increased Wall Line Count, or 100% Infill Density, although Wall Line Count seems better or at least faster, even though it's really 100% infill that I'm after.

 

Speaking of the Z seam, I'd like it to be at the "center of the bottom" of the part - a flat section, not a corner.  The only way I've been able to achieve this is to add a "fake" corner at that location via an extruded polygon (which I then grind off after printing).  Is there any other way to force the Z seam to be at a location that's not a corner?

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • 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 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.
