Is it affordable? I can not tell from their home page on the link you gave us?
If you click on each material featured on hat page, it will give you detailed information (including cost and the printing process) about each material. But metals are printed at much lower resolution than the resins, so their usefulness for small scale models is limited.

One last thing. I'm curious about what the guy in the last video said about doing 3-D printing in metal in the near future. Plastic is one thing. Other materials is another interesting step forward. Printing things on a molecular level, arranging atoms, could really change things. I wonder how far away that is? And how that will change the world? Again, pretty exciting.
Shapweays can print your designs in several different metals. That technology is already within hobbyist's reach. http://www.shapeways.com/materials/

Just don't ask any recent high-school graduates to make change from a dollar.
Yeah! You should see the expression on the face of a teenage cashier when the total is something like $4.48 and I give them $5.03 (or even better, $5.53)! They look at me like I have three heads (and I only have two).

Model. There is one very visible clue (at least to me). But the modeling and photography are superb.

Well, I can see Snake45's point about future being an inferior top clear coat for model cars. While Future results in a decent glossy finish, it can't be sanded and polished like standard clear lacquers or enamels. Many modelers strive for a mirror-like glossy finish. They get there by first building up a thicker layer of clear, then spend hours sanding and polishing it until it shines like glass. You can't build up a thick coat of Future and then sand/polish it to the same level of shine as you can with other clears.
-
Looks like in this example the decal was applied over flat paint. So, it was barely stuck to the surface, making the removal easy. Most modelers apply decals over glossy surface while also using decal-setting solution. Those are almost impossible to remove. Also there are different thickness of decal film (depending on the manufacturer). The thicker ones woudl be easier to remove than the thin ones.

Seriously, I'd love someone to make white-metal mirrors with a built-in mounting rod that would go in a drilled hole. Now THAT arrangement might be durable enough for me to worry about putting them on.
Do it yourself. Simply drill a hole in the mirror stem and glue in a piece of brass rod. 0.010" rod is a good size (for 1:24 or 1:43 cars). I always pin the side mirrors to my models. I pin most of the small parts which are designed to be glued to the surface.
-
All these variations in color make me think that maybe the color depends on when the car was made during production run? Could that be a possibility? Maybe some had a body color pan while others had light beige or gray pans? I'm no expert mind you, and I don't play one in the online forums either. But I own one of those (still unbuilt) models.

I don't think that the small producers of cast resin parts or kits need to buy a 3D printer. There are several companies which offer high-end 3D printing services. As long as they are provided with the appropriate 3D drawing, the can print the item which then can be used as a master for resin or metal casting.
There are several kit producers which do this already. I have a recent Tameo kit of a 1:43 F1 car and many of the white metal castings have very faint striations on them (indicating that the master was 3D printed on a high resolution printer). Showcase Miniatures vehicle models also have metal-cast parts which under magnification show some faint artifacts of 3D printed master.

So, it was that car after all. It just seemed way too easy.

With all this talk about autonomous cars all communicating with each other or cloud computing power, nobody has raised the possibility of hackers breaking into the car's computer systems or into the entire inter-car communication system and creating havoc (maybe even causing accidents). If we look into any current computer devices, they are all prone to hacking - even the super-secure government network. The problem to me seems that the size of the software (in millions of lines of code) has become way too complex to manage properly. There are many people or entities creating various pieces of the code and then someone else integrates them together (or uses set of libraries from another source). This is just ripe for back doors or vulnerabilities. I don't want someone hacking into my self-driving car's computer and forcing it to slam into a bridge abutment at 60 MPH!
Even now (remember Toyota's self-acceleration bug?) cars have buggy software for their non-autonomous systems. Imagine a system 100 times more complex. . .

What I do is not using runners to cast rubber tires. I have a mold that is two halves. Pour liquid flexible resin on the both sides of the mold, and then carefully join the halves. Usually, some resin will "bleed" out on the sides, and lot's of air bubbles also come out this way.
Until now I had no problems with air bubbles on the tires.
Interesting - thanks for the tip. So the liquid rubber is more viscous than typical liquid resin (so it doesn't just pour out of the mold half when you tilt the molds to join them together)?
-
Thanks!!
No, I don't pressure cast.
WOW! How you you avoid air bubbles trapped in the mold? Especially in the ridges of the tread.
-
Silly question: is the airbrush really clean?
The chrome paint needs to go on almost dry - that is why they recommend very low pressure and spraying close to the model. When I do it, when the paint first hits the model it looks like matte aluminum, then as it dries, the little metallic platelets align with the surface of the model and it becomes "chromey" looking. You can actually see it turn into chrome finish right in front of your eyes.
-
Very impressive! Even the surface finish looks perfect - not too rough and not too shiny. It looks like rubber. Do you pressure-cast?
BTW, tires have tread, not thread - easy mistake to make.
-
Could the bottle of the chrome paint have simply gone bad? I have had Polished Brass go bad where it started clumping no matter how hard I shook or mixed the paint the clumps would not dissipate. Are you keeping the airbrush nozzle open wide enough for the metal flakes to go through it?
-
Maybe their attitude is related to the customer's attitude? Just speculating . . .

The shape is very familiar, but obviously it is not that car.

Didja notice that much of our new furniture is coming from these two places? When we bought our leather couches in our den there was a closeout of the style, because they had just shut down the US plant in the south and were going off shore with new styles. That was six years ago.
Anyone else notice that's when we got the stink bug infestation? Yea, beetle like bugs that eat crops and stink like heck if you step on one. They can hibernate up to a year.... as in sleeping in furniture in ocean containers. AND they are used in local cuisine.. used to give dishes a spicy taste, beware!
Five years ago they were everywhere. We are fortunate that the last few winters have been cold, which has killed a lot of them off over winters since they are a tropical bug.
That is an unfortunate result of this global economy. Here in the Northeast we have the stink bugs and even more destructive longhorn beetles. Both came from Asia.

That '62 Chrysler 300 interior looks more like Testors tan color (from the small bottles) than the darker leather color

I'm about to use Tamiya acrylic paints for the first time and I have a couple of questions:
1) How much do you thin it with the Tamiya thinner before spraying it through and airbrush?
2) Does it have any interactions with Model Master enamels?
3) Is there anything else I should know about this paint? It smells like it has a bit of lacquer solvent in it.
1) like others said - til it is as viscous as 2% milk. I never really make a note of the proportions.
2) It shouldn't - it has a fairly mild solvent.
3) The smell is probably mostly Isopropyl Alcohol. Like most others have mentioned, I say stick with its dedicated thinner - don't cheapen out and use substitutes.

This guy definitely deserves an award...
This is a fully functional scale airport with planes landing and taking off, lining up to take off, with monitors of arrival times and whatnot...check out the link for more pics:
LOL, isn't it just amazing? It is all H0 scale (it started as a train layout which grew and grew). I wouldn't call it a diorama - it is more like a huge model train layout, or maybe a better name would be an "exhibit".
It is also not just a guy - it is a team of dozens of people who work on this exhibit full time building and maintaining it. There is an entire Youtube channel devoted to this exhibit. They even show behind the scenes stuff (how it all works). it also generates revenue (you have to pay admission).

Very well done!
What surprises me is that even in large scale like 1:12 they molded the rear quarter window louvers as a solid pieces. I have couple of 1:24 ESCI kits of those cars and I'm planning on making those louvers as see-through pieces with 3-D printed parts (once I figure out how to design them).

Harry,
I stumbled onto this beautiful thread by chance. I have long planned to build a backdated version of the Christie kit sans motorized tractor. I already have two "Breyer" horses to pull the rig, and reference materials on the harnesses and other equipment that will need to be fabricated. I still need to source the front wagon wheels. Can't see buying an $85.00 kit just for a set of wheels. Harry, fantastic job! Thank you for sharing your step by step photos!
David
I have a partially built one I picked up for much less than $85. I assume you need a set of its rear wheels to use as fronts? If you promise to post some in-progress photos of your modeling I think those wheels can find its way to you.
PM me.
Water spots on final color coat
in Model Building Questions and Answers

I wash my in-progress models probably way too often and I have never ran into this problem. Very interesting. Did you just let the water droplets naturally evaporate from the model or did you towel-dry or use compress air to try to dry the body after washing?
Also, what type/brand of paint did you use on that model.
Barkeeper's Friend is a mild abrasive, so you are correct. And it didn't leave any residue which . . . needed to be rinsed off?
