Posted · How to print low resolution (300 microns) with ultimaker filament?

Hi...

i just print a low resolution (for the first time) gear but I suppose that I setup something wrong or maybe don`t level the bed right. I put the same temp for PLA 195C, speed 40mm/s to 60mm/s.

Finishing is terrible and the layers are not bounding... I forgot to change top and bottom heigh and it was just like 0.6. I never made a so bad looking print, I`m dissapointed :angry:

What I did wrong and how can I fix that for the next low resolution print?

    For thicker layers (lower resolution) you will want to increase the nozzle temperature by 5-10 C and slow down the print speed. This is to help the material continue to flow properly. This is from 3DVerkstan: "To figure out how fast you're trying to print you simply multiply your nozzle diameter with the layer height and speed. So for example, if you're printing with 0.2mm layers at 60mm/s you would do: 0.4*0.2*60 = 4.8mm 3/s." This shows how much plastic you're trying to extrude per second.

    Cura also does this for you if you hover over the 'print speed' field. When trying to force more plastic through the nozzle you want to allow physics to have a chance at it :)

    Thanks a lot I will try that! I had a vague recollection that needed to move on temperature, but was doubtful if needed up or down it. 8)

    Cool, but which parameters of plastic volume should I play around? I usually print PLA at 0.4*0.1*50= 2.0mm 3/s or 0.4*0,06*30= 0.72mm 3/s... what it means? Sorry if it`s a stupid question :D

    Yeah, that`s very usefull... I tryed to increase infill speed to 70mm and Cura advised me to stayed in 60mm/s hehehe.

    I really like Cura I just think that the software should improve in auto generating support, as well as edit those when necessary ... and about change temperature at a certain point in the peace, we have to always leave the same temperature, in some situations only change the fan speed doesn`t help. Because of that I`m thinking to move to simplify3d :(

    Despite my disappointment with this printed piece the customer was satisfied. I put myself available to redo but he (who had practically "forced me" to do in 300 microns). But he liked and was pleased to see her and touch her design... he said it was not for mechanical purposes and for him was enough... I felt relieved and offered a discount for next order. :PLast month I made an object for him at 100 microns which came out perfect! That was my lucky...

    Just up your temperature some, especially with a part like this which dosn't seem to have any extreme overhangs or details that would suffer severely from it... The result will be a stronger part with much better continuous flow and bonding layers.. I have heavy cooling on my UMO and rarely print PLA below 210 degrees

    Nice, thanks for that, I will definitly increase it! I don`t know if my temp sensor is one of those who has a delay of 10°C cause my prints looks much better with temperatures around 195-198 degrees for 0.1 layer high.

    Another doubt, I'm not sure how much the room temperature influences the final print setup, remembering that I live in Rio de Janeiro and usually work with a maximum of 28 degrees environment for print ... when the ambient temperature rises I turn on the air conditioning and put my sunglasses 8)

    I agree with @tommyph1208 that increasing your nozzle temp by 5-10 C should do the trick. Best of luck, glad to hear your customer was satisfied! :)

    I agree with everyone else. More heat.

    You asked what to do with the volume calculation. 2mm^3/sec is nice and slow. The printer can do up to about 8mm^3/sec with the .4mm nozzle at 230C (I know - you like to print cooler and indeed quality is better at slower printing speeds and cooler printing but if the customer doesn't care and you want to print fast, and there aren't a lot of overhangs, 230C or even 240C is fine).

    But for a larger nozzle like the 0.8 you can easily print double the volume (16mm^3/sec). I recommend never going over half of these limits (4mm^3/sec with .4mm nozzle and 8mm^3/sec for .8mm nozzle) because when you are right at the limit of what the printer can do you will get occasional bad layers (underextruded).

    With 0.1 layer height you are unlikely to need more that 200; quite possibly less than 190, if you feed system is trouble free

      • 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.
