Radio-controlled aircraft

Dear friends,
Good day to all.
I want to ask a respected community for some advice.
I have long taken up the project of printing a model of a "Kraga" radio-controlled aircraft. The case was progressing normally until it stalled in the production of wings.
This should be fine work and I basically do not like print quality.
I type on Ultimaker 2+, golden Pla / Pha filament from Colorfabb, 0% infill, no bottom and top.


I combined various speed and temperature settings. The result is negative. The default Cura settings for Pla do not work either.
Question 1: What settings (other than basic) can I try to print this part? Can someone also print this model?
Question 2: During the retract, the priter stops long enough. Because of this, a flat dot is formed at the stop. This is very dirty print. How to avoid it?
Question 3: Which one would you recommend for the best filament Pla, Ultimaker, Innofil, Colorfabb?
Thank you very much

    When used for a model plane, I'm not sure that it's the most optimal direction you are printing. all your cross bares will be very fragile. I would consider printing it laying down and using some supports.



    Sorry didn't see that it was a paid print project!
    Dit it come with print instructions? 


    I still think the print direction will make it weak. But they have probably tested and ment it was strong enough.

    I also think this is not the right direction for printing these models. Like in wooden matches: the grain of the wood should go in the same length direction as the match. Otherwise the match will snap if you try to light it. So this wing is likely going to be very brittle.


    It should be designed so that you can print all beams flat on the glass, and assemble these parts afterwards. So that it can absorb the forces and flex, like real wings.


    Meanwhile, for best strength, print rather hot and slow, but with fast travel speeds (so the nozzle doesn't leak while traveling through the air). I don't know if switching off retraction would help, or make it worse? It would surely cause more strings and be ugly, but I don't know about strength? Maybe you could cut out a small part of this design, and do a few testprints with various settings?


    Also, PLA may not be the best material: it is going to break upon the first crash landing. And it is likely to warp in the car, in a hot summer, while on-road to the meeting or airport.


    But I have no experience with 3D-printed planes myself, so it's hard to give good recommendations.

    The guys who developed this project with the aircraft in the instructions for printing are advised to print it in a vertical position and without support, although I agree with you that it would be much safer to place the layers along the structure.


    One of my friends said that of all existing PLA filaments Ultimaker's PLA is the best. I do not know how it is.


    Dear friends, thank you for your advice.

    I'll say you can't put it as a yes and no question.

    it varies from types within brands and colours.


    e.g. I like Ultimaker Tough PLA Black but can't get the Tough PLA White to work. same brand same type, only difference is the colour.

    MAX-eDe I like all there PLA colours except there blue which i think is to
    "calcium like" which makes it more fragile.


    I think PrimaSelect is easier to dissolve the Ultimaker PVA

    And so on.... 


    So depends on the project. In you case i will probably go fore Ultimaker Tough PLA for that extra strength. but again that delimits your colour choices.

    Yes, color is important, but properties are more important. 
    I am very surprised at the fact that Tough PLA Black and Tough PLA White may differ in their characteristics. May I ask, have you ever tried printing Tough PLA Red?

    No sorry. But I'm guessing that it will work fine. I have never had any problems with red filament in general.

      • 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.
