UPDATE: 1:300 / 6mm figure scale version available at shapeways!
get em while they're blisteringly hot and mildly radioactive. (erm, in actuality of course its perfectly safe plastic, I take no responsibility for any injuries caused by radiation, gaping jaws or excessive drool production clogging keyboards)
Currently in use with a black budget task force on the late night highways of the US and Mexico; it's existence is denied by the US Government, it's mission, classified beyond top secret. Never normally seen during daylight, the dark hunched form seen speeding around the border areas has become known as "The Devil of the Highway" and is associated with many burned out car wrecks (which appear to have been pummelled by high powered explosive tipped rounds) and mysterious deaths found in areas where the vehicle is sighted.
Based on the XMT-168 advanced APC prototype this vehicle is modified for use at high speed on paved roads: It features 6 wheel drive and 6 wheel steering, powered by twin turbo-shaft engines outputting a combined 2000 shaft horsepower. Aerodynamically arranged armour and double rear wheels help keep it on the road, along with a vacuum system (inspired by outlawed Chaparral race cars) that create low pressure areas under the hull around the front and side skirts allowing manuvering that belies its mass - which is minimal through use of composites and high tech materials. The turret has a faceted lenticular shape - similar to an AWACS radar that allows the turret to rotate and cause minimal wind deflection at high speeds.
To tackle rougher terrain, the vehicle can raise up on its double wishbone suspension and / or detach skirt sections for added clearance, it is also able to fit inside a C-130 transport and compact enough to be practical on a modern road network. The side effect of this is reduced carrying capacity for troops or cargo of its own. Effective Crew is a minimum of 2, typically 3 and provision for carrying a small number of passengers.
The model itself is built to be 3D printable and while it's also a scifi concept model its also an experimental test bed for very real world technologies that allow the printing of working suspension components, or of course any type of working mechanism.
I intend these to be printed as complete mechanisms at as small a scale I can get away with, perhaps even as small as for the 15mm figure scale which I can then order from shapeways. 3d printing is very much the wave of the future for manufacturing and more complex, more interesting miniatures with working parts that require no assembly are one of the (probably less useful;)) things that it will provide.
too shiny right now. good design, but completely lost if off road.
any chance of a system to lift up the skirts ? like some armored hydraulic pistons
you might want revise your title. de laS carreteras (or de la carretera, decide if its plural or not )
Suspension and steering are self contained modules - so i dont have print an entire vehicle for testing. you can see the suspension is very chunky to meet tolerance requirements. The suspension and steering are also rigged up using inverse kinematics so i can for example drag the central steering bar and that applies constrained force through the link arms to move the wheels and this responds no matter what the suspension deflection is, which is also an inverse kinematic setup - also makes animation very easy to setup and have working suspension in the animation, effects like bump steer are naturally modelled in the system even.
Having this setup is essential for tweaking the limits of the design for steering lock and suspension limits, so the twisting organic look of the wishbones is a result of making something thick enough to print and also be functional at a given small scale.
Ah, There was bound to be something wrong with the translation. As inept an error that it is, I'm glad thats apparently all it was... I'll amend the thread and further titles. thanks!:)
as for the shine, its been polished up for the above top secret publicity photos displayed here;)
3d printing.... so much future potential there - it's unreal. I could go on and on about 3d printing but I shall refrain at this time.:) I will say that I long for this tech to be revolutionized by the application of nanotech. But for the immediate future I would like to see larger machines with bigger bed-area. (So you can print out a 3-foot long Akula model!!!)
If I read this right, this is a mechinal concept study right? Hell, you got in on the groundfloor of this stuff so to speak so by all means push the bounderies of the possible!! What other features do you intend to add to this model and what features would you like to intergrate into future projects? Idk, posable, articulated landing gears for instance...
On the subject of 3d printing, a fan of First Strike had one of our more unique takes on an EU Star Wars vehicle 3d printed, it is his hobby to take rare Star Wars vessels and get them processed in this way so he can have a very original Star Wars model collection. The model he chose was my interpretation of the Rebel Armored Freerunner (very much an APC itself actually), he posted a few shots of the progress he was making with the build, the link of which I'll post here if you like. Unfortunately I didn't optimize the mesh beyond making it watertight for the printing process, so all the benefits that being an in game model are lost, such as smoothing, and the result is more angular than intended, and quite low poly looking. If he wanted another model I'd obviously rectify this oversight. Also the grain of the printing process is quite distracting, he's having to do quite a bit of sanding to smooth areas out which must be a pain. I think the place he took it to be 3d printed must be using quite an old machine, as I've seen fantastic examples of the process that include the integration of several different materials (rubber for tyres and plastic for a wheel for example, or even more impressive, a polymer skull within a rubber half of a human head) and a smooth as silk finish. It is really exciting to see what they can do with this technology. Any how, here's the link to this guy's 3d printed First Strike style Freerunner:
Incidentally, if you go to the images section of that page you can see the progress he has made so far with the painting process on the model.
I have produced 3d printable models for the best part of a decade, mostly for others. in the last year or so i've been producing a lot of original designs for miniatures companies, my own designs like these 6mm figure scale models for microworld
some of my other vehicle and mech sculpts are shown in my blog... http://coolhandgraphics.blogspot.com/ I have tons of other stuff to show in there but haven't updated it properly for a while.
So most of the models i make are for eventual use in traditional mass production processes, so i have to worry about molds and undercuts, sprues etc.
For my project here its important to choose the right printer or material, with a rough material there's no chance that working moving parts will be achievable, this will be printed in a much finer quality material, detailing goes down to 1/10th of a millimetre so the quality of the surface is much better. one of the materials this model will be available in are the frosted detail materials from shapeways which should accommodate the smallest scales.
Travis, as long as you can design it as a functional mechanism, within the tolerance limits, things like working landing gear are certainly possible.
I mean at some point in the future, this totally possible, that you have a 3d desktop that will make everything from kids toys to a new pair of durable, fashionable and practical shoes or tough spare parts for your car... with the right materials, the right colours etc.
Anyone will be able to produce designs that can be downloaded and printed at home, no middle men, no transport network, warehouses or all the other overheads associated with traditional mass production. ideally one printer could print another printer for your neighbour. So thats obviously a significant development that would have serious consequences for modern consumerism.
And thats not even getting into medical advances... But i'm sure i've talked about all this before and there's lots of speculation out there about what will and won't be possible and I could talk about it all day but this post is already way too long.;)
Thanks for the comments all.:)
In this pic the roof is a separate piece that can be removed to allow access for painting etc. The entire model breaks down into 6 sections (incl the 3 wheel assemblies) which should fit together fairly easily.
here's a quick vid of the suspension in operation.
I like the way Coolhand posted it as youtube is blocked where I work
Thank you for the comments guys, Travis to answer your q, the steering is entirely conventional but is only modelled as far as the drag bar - so i have single point that i can manipulate to steer both wheels. In a real vehicle that would be acted upon by a rack and pinion or other similar device - a direct mechanical link to the steering wheel. in a radio control car, its the point that you would hook a steering servo up to...
A full size real world equivalent of that would be an electrical "drive by wire" system - which also allows autopilot and remote control easily.
So, umm i suppose what i'm saying is it could be electrically moved (not a bad idea) but that's still going to act through a drag bar, through the control linkages to rotate the uprights. so it's not an excuse for skimping out on mechanical detail, i could have wimped out and said it was a motor or something on every kingpin to rotate the upright and just said its scifi (and fair enough) but it's built to work just like most modern vehicles.
I had some ideas about linking each steering/suspension module up with control arms, so moving one will move the others - with an appropriate angular offset so the forward steering moves to full lock while the rears are rotated somewhat less. I really just want something that people can 'pose' as a miniature on terrain or to illustrate cornering, braking etc... and also as a miniature mechanism to play with and marvel at the technology of 3d printing. From a creating animations POV it I could use some scripting to control it and i will hopefully be making some sequences with it. Good thing I have the youtube account now.;)
Oh, btw, I would love to see you apply this concept to a vehicle more situated for off road. Any thoughts of eventualy testing out mechanics of tracked vehicles? Or is it even possible to create sturdy linkages that small(unless they were metal of course)?
And update your blog!!!
you could have the tracks working, suspension/road wheels etc. maybe even print a working torsion bar for suspension.
As for metal, you have to melt it together so if its possible to do moving parts with it you'd have to allow even more room between parts, so its not good for small scales.
(no one reads my blog;))
Bridgstone Airless tire design
Hummer Airless tire design
Both of these offer a certain sci-fi look to them as well.
From the apparent weight of the vehicle you may want to not make the tires completely airless but a partial airless design could be quite useful. I know the tread you chose has a it's noise deadening properties needed for such stealth ops but there is perhaps a trade off with that of safety of the crew should something happen. Can't really call the AAA to have them fix a flat on this guy
I love your back story to the vehicle too. Would make an excellent movie/TV series. Similar to the Highwayman/Airwolf or other lone ranger kind of story. There is of course the post apocalyptic movie Damnation Alley which also springs to mind a bit too
Your work is always top rate. The rapid prototyping stuff (3d Print) is awesome too. I've often thought of unwrapping a model to be made into a card stock model. Somehow having a physical model can help creativity. Don't know if it's because it unties you from your computer to view it or it's presence in physical space but I would think it would be awesome as a model (physical model) perhaps even RC if you're ambitions lead you there?
The wheels are about 150% the size of semi-trailer wheel. I could even fit larger wheels/tyres on it but it starts to reduce wheel lock etc, which impacts manoeuvring in tight spaces. You can fit a larger diameter tyre, but slightly thinner, which is the off road wheel.
Its also a bit smaller than it looks, its 2 meters to the roof when lowered... Which is a lot smaller than a Landmaster, for example.
I'll probably make some different types of wheels, I think putting more conventional tyres on it gives it a more contemporary look, or if you wanted a more futuristic look, that can be obtained with a different wheel. There are definitely technical issues with producing that fine type of pattern, wall thickness etc, at a small size but it would be interesting to experiment with.
As for the tyres, Pneumatics have all sorts of issues beyond getting flats, and it would certainly have something to make them more resistant; perhaps they aren't pneumatic, but simply look similar?;) Interesting that Ronson picks up on the "stealth" aspects of a tyre, because that would surely be a factor in such a vehicle. But that presents exactly the same problems that commercial manufacturers face: They also want a quiet tyre, easier on the driver ultimately; less noise, vibration, but also good road holding and so on. So its deliberately very similar to a commercially available design.
As for printing a larger scale for radio control, it think that's do-able but best to use lots of off the shelf components like nylon gears and bearings; a high speed gear box made of printed materials will probably shred or melt within minutes of use.
Oh, and 3d printing... that beast would make a wicked, wicked WH40K Rhino alternative... hint, hint..
In any case, nice work Coolhand, indeed it was your work on this and the Shapeways thing that has made me rejoin.
Any tips on working on stuff for that, because i'm trying to design a tabletop sci-fi wargame (Space based for now as I suck at people still) and Shapeways seems to be a little short on information for things like scaling.
Kadaeux, not sure what you mean, just make sure all your parts meet the specifications for minimum wall thickness, etc, according to what is listed on their materials page and you should do fine, at least they wont reject the print anyway.
Meph, well thats a possibility... if you wanted a print in a different scale for modification, when its finished its no problem to scale it up a bit.
Freak, Thanks for the support.:)
