  1. I have an idea, we need decals for the Mitsubishi F-1,T-2, F-2 and for the Kawasaki T-4. There are tons of paint schemes out there for them.  I know there are some decal sheets out there but they are hard to find and harder to get.

    Yes,it is little bigger than L-29 and it would be great looking model kit.

     Yes, Yugoslavia had great aviation industry.

    I have great reference materials for this model kit,and all what is neccesery to made regular model kit.And I meen ALL...Plus long time expirience in military aviation.

    I would like to find company who would be interested in making this model kit.What is good,I think that it can be great earn of money for them,because people are very interested in this subject,and as you have seen and mention,it can be build in so many variations and paint schemes.What I dont want is any money from this project,and I write this public.All I want is that model kit 🙂

    Yes, but people say the same thing about the T-37 and still no 48th scale kit

    Do you mean FDM (spools of plastic filament)?  SLA is a resin process (the photon is a form of SLA printer), so I'm a little confused.

     

    Anyway, for the Photon, I'd suggest running a test print with .2mm wide/deep panel lines as a starting point (just make a quick, vaguely wing-shaped piece and deboss some random panel-line shapes on it).  That should give you some nice, very sharp panel lines about the thickness of a sheet of paper, once you factor in the slight overcure you tend to get with the Photon.  If you think they're too fine, you can jump up to .3mm and try that.  Since panel lines are kind of a personal preference though, you'll need to dial it in to your own personal tastes.

     

    For the Creality printer, assuming it's an FDM (CR-10 or Ender family), my first suggestion would be to NOT add panel lines. The relatively thick nozzle diameters and layer heights mean they don't really turn out well in the first place, and the surface filling and sanding required mean they're easy to obliterate anyway, so I'd save the time in CAD and just scribe them once you've printed the parts.  (also, pro-tip: save yourself a ton of time by switching to a .8mm or 1mm nozzle and printing in vase mode rather than standard multi-perimiter + infill.  You can print regular bulkheads to add strength - it's what I did for my 1/144 Hindenburg and it saved literally weeks of print time).

     

    If you *really* need to do panel lines on your FDM print, it will depend on your print settings.  You'll need them to be at least a little thicker than your layer height in the Z-axis, and wider than your nozzle diameter in X/Y.  I'd run a test print with .25mm along the X/Y axis (parallel to the bed) and .45mm Z (perpendicular to the bed) dimensions, and tweak settings from there.  You'll also need to turn your print speeds way down to minimize ringing from the 'vertical' lines, since they'll be sharp movements for the print head - if you're printing ~80mm/s+ you'll probably lose the panel line detail in the ringing/ghosting; 30 - 40mm/s gives you a better shot at having usable lines.

     

    And a last pro-tip: use your Photon resin to fill/sand the FDM prints.  It self-levels nicely, sands really easily (especially if you're printing in PLA), and is much, much easier to work with than putty or spray primers.  The only real downside is that you're liable to fill in any panel lines you've printed, so again, it's probably faster and easier to just scribe them in to the smoothed print rather than waste time in CAD.

    Thanks for the advice and correcting my terminology. my FDM printer is a CR-10.The more I read, the more I think that drawing or scribbling the panel lines will be the best way to go.  On another project I'm working on I found that printing the fuselage in "ring" sections seems to work best as appose to printing them in traditional left and right halves.

    Is home 3D printing really at a level where you can print a quarter scale model without a lot of finishing work?

    Yes and no, weather its printed FDM or with Resin there will still be a post print process that will need to be done to make a perfectly smooth part. But I'm not expecting to print Tamiya quality kits

    Depends how you're printing them.  FDM will need to be bigger than SLS, which should be bigger than MJM or mSLA, which will probably be bigger than a high-end SLA.  Part orientation can have an impact, too - horizontal lines on an FDM print can be a lot thinner than vertical ones, due to the way the plastic is extruded.

     

    What is it that you're modelling, and how will you be printing it?

    MoFo,

     

    I have a Creaality ALS printer and a Anycudic  resin printer. I'm going to print the main parts  (fuselage , Wings.etc) in SLA and do detail parts with the resin printer. I know I'm going to have to do some work on the SLA parts to get a smooth finish,but so be it.

    Right now I,m  drawing a P-8A Poseidon  in 48th scale and I have plans for many other planes like a C-23 Sherpa, T-1 Jayhawk, T-37, TT-1 and a few more. 2020 is going to be a busy year of drawing for me

    Building aircraft flown by NASA has been one of my longest running themes. As the NASA F-104 has been served in model form by both kits and aftermarket decals in the major scales over the years, my preference would be for the more unusual/less aftermarket decaled NASA aircraft from Kursad. In 1/72, the NASA Tomcats, Harriers, Hornets all would be appreciated along with the ex-transports in 1/144. For those of you with an interest in NASA aircraft, I started to put together a database years ago of NASA aircraft that I could confirm with a solid reference or photos. It can be found at this link: http://www.ninfinger.org/models/nasacrft.html . Note that I have not had the time to update it in quite a few years but I betcha you will find some aircraft that you did not know were flown in NASA or NACA markings!

    Have fun modeling

    Mike

    :cheers:

    MIKE,

    Athought I agree with you there have been many NASA subsets over the years, I think there is room for new ones. Take the 1/48 F-104. There are kits out there which include decals for a NASA they are not so great. The the decals in the Hasegawa NASA F-104 kit was brittle and nearly on usable. Plus I haven't seen a sheet that covers the TF-104G yet.
