Printing Text and Figures on a Flat Surface


Recommended Posts

Posted · Printing Text and Figures on a Flat Surface

Hello, I have a question I’m printing a Text and a Figure on a Wall Hanging Plaque I sculpted in ZBrush. It’s Watertight and all the Text Letters and Figure start on the same layer.  Is there any Setting, Script or Model Creation Technique that I can set the text and figure to start printing at the same layer after a completely smooth flat layer has completed?  Cura 4.12.1 slices my model so the infill continues from the bottom for both the text and figure making the surface not as smooth as it could be if the text and figure started printing after a flat layer.  Photos attached.  Any suggestions would be appreciated. 

Thanks Paul

I'll just hijack your thread, because it seems we both have the same question. Especially useful for me would be the option to have Cura iron the whole flat layer before printing the text/details. The model on the right is the best I've been able to achieve so far with tuning the ironing settings, but since Cura won't iron the part where the details will be printed, you can see the printing and ironing artifacts around the outlines.

Is there a way to have Cura basically treat the base as a "complete" object, printing the details on top of it? As in the screenshot, I'd love for the layer right before the details start to be completely flat, disregarding anything that comes above it.

Setting the top layer count to be equal to the layers of the details will create half of what I'm looking for, but the ironing still goes around where the details will be printed (slightly visible in second screenshot).

    I think both of you need two models.  One would be the base and the other would be what goes on top.  You can do this in Cura.  Bring the base in on the build plate and bring the upper portion in at a Z to sit on the base.  Using the Per Model settings you could have the base piece ironed and the upper part what ever you want.


    I've printed a lot of these drink coasters using two models.  I've adjusted the Z here so you can see that the top layer of the base on the left is ironed, and the first layer of the words and rim on the right have no bottom layers (in this case, it just doesn't need them).  I usually use Pause At Height and change the color for the upper part.

    Yes.  Make two models that don't intersect with each other.  You may have to raise the Z value of the text so it sits at the right height.  I just did this for a print 2 days ago.  You can do this even if your printer only has one extruder - in fact that is the default where the same extruder gets assigned to all models.  In my example I had 2 extruders with 2 different color filaments.


    I didn't use the ironing feature but it would have been easy to do so.

    If you want to get really fancy we can teach you to merge two or more gcode files together at a height so you can mix layer heights and line widths and even print different sections with a different size nozzle.  It's a bit tedious but not bad.  The hard part is watching (with your fingers crossed) as the printer goes through a transition area of the gcode 9 hours into a print and you're wondering if you got the transition code right.

      • 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.
