Model (miniature) Atoms
Re: Model (miniature) Atoms
Getting ready to send in the third print. Completely revamped the steering system to a rack and spur system. The stock steering is way to small and compact to mimic at 1/24th. The steering system uses "trays" at the wheels and a very large rack that in real scale would be better suited for BBQ. I am a little concerned about the gaps in the linkage, but, I would be more concerned about a fixed linkage breaking.
I added a girdle for the shafts and came close but did not add a third shaft last night. The complexity of the third shaft is something to be avoided when the goal is a proof of concept, well at least that is what I talked myself into. The two shafts are actually three and I have now triple verified that I have enough "walking" room between them. I also added outer drive shaft support to reduce gear binding that is occurring on test mule 2.

Re: Model (miniature) Atoms
The engine thing was interesting, but, it is still not working correctly and I am moving on. The working frame model print is now done and it does have rolling, steering and suspension all from a static print. I am very happy with it. I have placed two slightly different designs up on Shapeways if you want one. One for existing model tires from Pegasus and one for hard plastic r888's.
Hard plastic tires printed and good to go http://www.shapeways.com/model/913157/ariel-atom-1-24th-scale-model-w-tires.html?li=productBox-search

Re: Model (miniature) Atoms
If someone wants me to, I can easily change the steering to the other side. You will have to live with the Brammo frame and the steering on the wrong side thougjh
Re: Model (miniature) Atoms
Jumped back into the tiny Atom project to make an Atom pendant gift for the wife. What I came up with was so close to HO scale I just enlarged everything I was doing to make it exactly 1/87 scale. I took the frame that was done and modeled almost everything else again. I have ordered a gold plated brass as the test version. I will have it mid October. From what I have read most of the model detail will remain, although I am concerned about the spokes on the wheels as they as just below what is approved. The treads in the tires will be gone. From the test, I may end of thickening the spokes amongst other items.
If it looks 77% as good as these renders, I will be happy. Rendered with an iPhone 5 model

Re: Model (miniature) Atoms
That would look fantastic Norm - hope it comes out that well! If it does, I'll be ordering one.
Re: Model (miniature) Atoms
Be rather nice if it was double the length of a phone - about the same size as a die-cast model
How much does something like that in the small size norm cost to produce? Can you put a price on it?
Excuse my ignorance but it is fascinating this printing stuff malarchy.
I can see in the future no need to order car parts - you'll just be able to print yourself one.

Re: Model (miniature) Atoms
If it was hanging on your neck you would not want it double the length of a phone . I have been assured by my wife it isn't too big right now, but, that is my fear.
Strength will be an issue for printed car parts, sometimes you just need forged and machined. I have done some survey instrument and vacuum parts for old antiques that just don't have a parts supply anymore. It felt good to be able to do that. Printer accuracy has improved dramatically in my short time in the industry and shortly we will just print the molds for casting. Molds do have a lot of material though, so, cost may keep it to prototype-mold-part for a long time.
Jewelery is actually printed in wax and then a jeweler takes over and does the ole' lost wax casting process. Printing in wax did not concern me, it was making sure that it had enough flow to all the parts for the molten metal. The big hook in back goes all the way to the firewall for that reason. The motor mounts would never have given enough flow to fill the engine with metal and it would have been a two cylinder or worse. These pendants are right around $100 for gold plated brass, solid gold and platinum will take your breath away on cost. Here is the link if you want to see costs as they are different in Europe http://shpws.me/vVkA, I have a test print going now though and should have it mid October. They take 1 month to make. I added the bubbles to what is on Shapeways now, but, I kind of like what the test print is sporting myself. I see no reason not to have a couple of different versions in the end.
I have two projects over the winter for this base model, one will be a true 1/24th scale kit in plastic the other will be an Atom in crystal for my desk

Re: Model (miniature) Atoms
these would be a fantastic addition to the Atom key ring. If they come out nearly as good as the mock up looks, you can add my name to the order list
Re: Model (miniature) Atoms
These are jewelery in these metals and are designed to be used as such. If I were given one of these and were to give it my usual bull in a China shop treatment, I don't think they would hold up. The small wires are 0.8 mm. Printed steel has much thicker guidelines and is the material suited for a fob. It has a 3 mm minimum design and after I receive the jewelery, I will look and see if I can make something in stainless. Now that you mention it I would like one as well, as I am still using this print which is a little simple

It's a good point, but a shame for me, I was thinking of using as a keyring, but you're right... wouldn't last long.

Re: Model (miniature) Atoms
I just revisited the standards for steel printing and it is a lot better than it used to be. The old standards were 3 mm minimum, period. Now you can go as low as 1.0 mm supported. I am still going to wait to see the brass print to see just how tough it is. Regardless, it will more than likely be without wings as they would be weak points and I might enlarge the tie rods a lot to make sure they had strength. Other than that it does look do-able now and it is about half the cost.

The thing to remember about printing is that volume goes up as a cube. Cost is based upon material used by volume (there are some static costs but they are not the huge factors). So roughly 2.5 times to get to the length of the iPhone and then twice as big = 5x5x5 = 125 times the cost.
I was thinking more along the line of acrylic for the desk
I have zero knowledge on the acrylic car and if it is even possible, but, the horse is just an object as a stereo lithography file that is turned into small occlusions in the medium. The horse style is fairly easy to do now that I have a complete model. When I first looked at this a couple of years ago, they could not work just from a laser scan

Thanks for the bump that got me thinking fobs again. Shapeways has changed their design standards a lot and I have re-designed the HO scale Atom to the new standards and submitted it for print. It got rejected due to the lettering on the tires, so, I removed that and it has passed check and is being printed in nickel steel. A fob is possible! It will be here the first week of October a full week before the brass print ordered before it.
