    I have my own resin printers, two Formlabs Form 1's and a Photocentric HR, if you go back a few pages there are pics of prints.

    "Realised something which now seems really obvious, the ice floe model was painted the more plain grey/black to match the footage of the full scale version."
    I'll paint mine black. After all the conversation,earlier in the thread, about colour, what nobody seems to have realised is that polished black paintwork acts like a mirror.On a nice sunny day, just look at the bonnet of a black car as it comes toward you. It looks blue. All the hanger scenes also show the aircraft as black,with red markings.
    Those new renders are really good too!:thumbsup[SUB]

    As this thread has developed over three years, and technology has progressed along with it, I'm curious: what is the current thinking in terms of making this available to us to be able to make? Are you still thinking of making a kit? Or will you make a version of your designs available for us to purchase and 3D print when you've completed them?

    When this all started, the ability to print anything was beyond many of us, but now that 3D printers have become so accessible... well, just wondering what are your thoughts?

    Making kits is definitely the goal, I admit I have ended up with the resin printers on a maybe 20% work prototyping 80% personal ie Firefox printing basis. I managed to get all of them at serious low prices just by luck and a bit of a gamble, especially with the Photocentric printer as it was relatively new, but not well known and 0 official reviews. I still have to finish repairing my second Formlabs Form 1 as it was a kickstarter version and the laser assembly focussing lenses were literally tacked in place with superglue. One of them was at least 3 degrees off straight and the beam focus was terrible with what they call "rabbit ears" which cause printing errors. I think I will have to CNC a new part from brass tube to be able to mount a decent 3 element focussing lens, the cheap Form 1 clone I have working perfectly with a new diode has one.

    1/48th scale would be very hard to produce at a reasonable quality level on the best FDM machines even with a 0.2 or 0.3mm nozzle, maybe the body parts as long as you don't mind a lot of work sanding and re-scribing panel lines as they will be 0.2mm wide or 0.007" at 1/48th. You need the resin printers with sub 0.1mm X-Y resolution for it to really work.
    I haven't talked about pricing as I didn't want to upset the mods as I think you need to a premium account for selling.
    All I will say is at a well educated guess Shapeways for example would want around maybe close to $1000 to print a 1/48th model, I would be looking at around a tenth of that.

    Bigger scale, maybe 1/36th or so would work better on FDM for the all but the high detail/thin parts, so I could do a hybrid kit, part files for self print and a set of resin printed parts.

    I will admit I am picky on the end result, this is a man who spent more than a day sanding and priming a Powerpuff Girl for my niece, because I thought the FDM print wasn't good enough!

    Also revisited the colour, and think I got a bit wrapped up in the blueness of the blue... The darker sections are more grey/blue, but 60-70% is more towards grey with a slight blue tint
    Firefox grey blue 2.jpg Firefox grey blue 01.jpg
    I need to add some more subtle panel variations to make it looks half way correct, as there are at least 5 different shades on the models, with graduations in-between or overlaid. The originals primer did have a blue tint to it, so that affects the colour towards the blue part of the spectrum.

    Interestingly on the real tailplane moulding I have the resin looks blue/green with a plain grey primer splashed on. Obviously the colour this appears on your monitor could be way different so could be hard to tell.

    And yes they hardly show up to the eye but they actually put rivet markings on the masters!
    It's actually a very thin resin skin with a foamed polyurethane infill, weighs very little.

    Got a bit ahead of myself, knew I had to fix a few little things that would be an issue at 1/48th and fix a few bugs (one really hard to find) to get the part watertight. Also had to add the stand fixing and internal supports so it hangs together while printing. I had to do this part in different software as it handles merging/intersecting STL's much better than Sketchup, and I had used it a small amount but realised I was still on that initial steep learning curve.

    However the good news is I am essentially on holiday this week so once I get back from a small errand I can finish the supports and get it printing, it is going to take nearly a day to print, so really want to get it right first time!

    So after spending around an hour setting up the print job and adjusting supports just so, realised I had forgot to integrate two underside greeblies into the model, AAAAARRRRGGGGHHH!

    After that and then a software crash - note to self DO NOT have one of the slice images open when the slicing completes as it makes it crash.

    So, It's nearly 4am, but the print has been running for about 2 hours and looks ok, so hopefully I haven't make any stupid mistakes in editing the supports and when I get up there will be about 1/4 of a Firefox to take a picture of.

    Pic of what the part looks like in the slicing software, so you can tell what you are looking at ;) The software somehow estimates the print time at around 3.12 hours!?! Think that might just be a bug, lol.

    Photocentric Studio.jpg IMG_20180612_125021.jpg IMG_20180612_125012.jpg

    All going well by the look of it, the resin is quite viscous so hangs on around the support joints and the panel lines, you can makes some of them out in the pics.

    Looks like it will finish around 2am, so around a 24 hour print time. It's actually comparable with the time of an FDM print considering it's 50 micron layers, around 27 seconds a layer.

    Photocentric Studio 2.jpg

    Oh and a pic that shows the other side of the print, tricky bit will be the really thin probe parts on the tailplanes, if they get messed up I will cut them off and print separately.

    How dare you insult the colour of my resin ;) they call it cream, it does look banana yellow with the flash, still a bit more interesting than grey...

    IMG_20180612_180942.jpg IMG_20180612_180908.jpg

    Emerging from the ooze, going well, hard to see but the small vent detail on the top of the engines intakes and the airbrakes on the wings look good. Also the super thin probe parts on the tailplanes are good at just over 1mm wide, bodes well for the canopy struts printing ok.

    I left the intake vanes out as they are 0.5mm thick correct scale which I don't think would work. If 1mm plastic looks ok then I will add them to the next print.

    Oh yes, that's looking good.
    As for the intake vanes, what about some thin brass sheet? How many vanes are in each engine intake? Each modeller could supply his own- just a thought...

    I had thought about brass, there are two per intake - 8 plus one small one at the front. Would be easy photoetch artwork to make, they are small only 20mm tall. At a quick estimate around 8 kits per standard sheet size, so wouldn't add much to the cost.

    Part printed ok apart from the last bit. I thought it was a gamble as when a part of the print closes it can trap air and the oxygen inhibits the curing, thought the area would be small enough not to matter, *.

    Cleanup was fun as it was too big to fit in any of the containers I have, so had to do it the hard way and bath it with IPA with a brush.

    I feel in a glass half full mood because it's not completely ok, but it's like 95%+ perfect and just changing the print should stop it from happening, have a couple of ideas to try.

    The part is sunbathing at the moment, will post pics later when it's cured.

    Better late than never, went to my Dad's for dinner last night and watched The Departed, maybe 5th time for me 1st time for my Dad. He enjoyed it apart from having trouble understanding the Boston accent :)

    IMG_20180614_131119.jpg IMG_20180614_131314.jpg IMG_20180614_131715.jpg IMG_20180614_131705.jpg IMG_20180614_131524.jpg IMG_20180614_131635.jpg IMG_20180614_131437.jpg IMG_20180614_131150.jpg


    Print actually took nearly 30 hours at 50 micron layers. Haven't done any cleanup yet,intakes need flattening where there is excess from the support points. All the tiny details came out great, quite surprised about the tiny little points off the top of the tailplanes, the little fin bits next to them are missing about 50% they were just too thin, about 0.25mm, little bit thicker should fix that. Airbrakes on the wings are slightly soft, but I'm being super picky there.

    Have worked out that the slightly thick thin effect (slight band across the wing and near the exhausts) happens when there is an outer shell and inner shell with a void in-between. I'm guessing the resin either swells or contacts when it's curing, so need to fill those parts and possibly thicken the shell overall. Pretty sure the split behind the tailplalne is from a similar effect, think if I taper the inside so the last part prints solid should fix that. The small under engine parts will have to be printed as a separate pieces I think with an optimised orientation.

    Will be quite an easy kit as that's about 50% of the plane in one piece. Working on organising the front print, can hopefully fit all the other parts into the same print job.

    Hi guys, had a commission for two, yes two! 1/18th scale birds, the larger size actually lets me see that I did finally get the neck shaping right much easier than at 1/24th scale.
    IMG_20181004_185019.jpg
    IMG_20181004_185114.jpg
    IMG_20181004_184736.jpg
    So my first complete ones will be 1/18th, bigger is always better, eh ladies, ahem...

    Have changed the Z drive on my big printer since these as I was still getting uneven banding, most noticeable the neck part around the canard cut out near the top of travel. Could not get a good alignment of the motor to threaded spindle, think the coupler was causing an off centre fit, the wobble causes a stretch/squish layer banding. So with the fixed spindle motor out my older printer and a bit of adaptor metalwork should now have a perfect 0.04mm increment stepping Z drive, there is a neck part printing now which looks good.

    Have not given up on the 1/48th scale version, just going to get these out the way first, print time is around a week and a half for each one.

    I haven't been following this thread because I always thought that it was a smaller build, even though I do love the aircraft. I had no idea that the work progressed this much and even became larger. Great work.

    After a bit of Dremel action to cut off the extended support part for the front
    IMG_20181006_160740.jpg IMG_20181006_161649.jpg IMG_20181006_161029.jpg
    Tabs on the blue ABS part hold the front on tight, there's a tiny bit of distortion on the bottom edge, extending the waste part by 3mm for the next one. Also somehow turned off the slice anti-aliasing in the slicing software so the 0.09mm pixel steps are visible on nose. There is bit of distortion on the front canopy beams where they meet the body, discovered the wall is a bit thin there so that needs thickening. The recesses around the canopy are for 0.75mm acrylic sheet for the canopy glass.
    IMG_20181006_160635.jpg IMG_20181006_160605.jpg
    Air-brakes came out nice at 0.1mm layers, thought they might need 0.05mm resolution but doesn't seem necessary. Need to fix a few shallow panel lines on the main body part then get that printing later.

    IMG_20181006_161126.jpg
    New Z axis drive has improved the surface finish a lot, new left old right, the photo shows the belt noise, but it's only microns deep. Really tight drive belts on the printer improve accuracy and lower noise, but it does show the stepping/ringing effect a bit more.

    Hi Everyone,

    Just joined up to say what an amazing thread. My favorite fictional aircraft and everything I could ever wish to know about it is here. My son saw the film for the first time the other day and he is hooked too. He's been flying the Firefox in X-Plane for the last few days! I could write a thesis on what is wrong with the film, but the plane is just great!

    Annoying how the camera makes the surface noise look worse than it really is. Have a built in stand mount for 1/2" AF hex brass. Someone wants gears down so there will be gear bays for this version, have to build them but they are relatively simple, and have the F-4 Phantom landing gear from a free to use model.

    Waiting for some filament to continue the engine section and other wing, Working out print jobs for the other high detail bits cockpit, tailplanes, canards, airbrakes, leading wing edges, ailerons, defence pods and rear engine section, looks like 4 or 5 print jobs to get them done.

    Don't think I have posted most of these, screenshots from the blu-ray. Full size under studio/indoor lighting

    Full size where you can see the panel toning they did more obviously

    Looks like metallic grey car paint, tending towards a blue/grey tint.

    R/C conversion ice floe landing model, looks darker, but they were just doing there best to match the lighting.

    The base paint on the big models was a grey primer with a blue tint, and the lighting enhanced the blue to simulate sky reflections

    I think as close as you going to get to what it would look like in person is this one.

    These latest posts are glorious - and thanks for the wallpaper!!
    Just one observation though - is the canopy frame a little too thick on your print or is it down to where the window panels actually sit?

    That's an incredible miniature you're creating, i can't wait to see what kind of paintjob this will get.

    I absolutely adore the gleaming hull in the movie miniature shots. :)

    It's pretty much identical, but the large filming miniatures had no physical frame for the front edges as it was holes cut in the thin shell with 0.04" clear acrylic glued on the surface. With the paint and clear coat layers it mostly hid the step, you can just see it in a few shots.

    The print has what would be a "real" internal structure, so it's more visible.

    There is enough strength that you could lose the front spars and just have the 0.75mm acrylic to be more accurate to the 1/12th ones. The full-size mock-up does have an impossibly thin canopy frame.

    Thanks Rich, I hope I can do it justice. I have a few parts to do paint tests on before I tackle the whole thing. Will probably get a polyester primer basecoat put on by a car paint shop as it's a similar grey/blue they used. Then a 1k topcoat for the shine.
