I have a pair of 1/25 aluminum flathead heads done by my friend Pico that have to be seen to be believed. Only a single coat of Duplicolor primer made them just hunky dunky. But I guess they don't really exist, eh?

 

And don't forget, bumblebees can't fly (according to some outdated understandings of aerodynamics). The bumblebees didn't know that, though. <_<

Bill are these straight from the printer ? I wonder what machine he is using.

well see now something like a finned flathead cover would be the ideal thing to produce as  you could theoretically align the fins with the inevitable stripes that were apparent at least on my copy, caused by the "printing" head moving back and forth as if hoeing a field into rows. so it  might be quite possible to produce a finned item in 1/24. but lets see a near-polished surface straight from the printer as most good resin casting these days produces.

 

keep in mind I bought the base motor at least a couple years ago. things have moved on quite a bit since, but still I would like to see what could actually be done in 1/24 but so far what ive seen has been pretty crude compared to a nice casting.

You asked for it, I'll give it.  https://www.google.c...nter%2F;460;512

ok but the thing is, in most of the websites linked to the photos from that google search, there are a lot of objects that I cannot really tell how big they are, and the ones that you can, like the miniature Eiffel tower, its a subject that lends itself to a straight line sort of process that hides the problems with the three D printers. can you show me an image of a 1/24 scale say engine block with a smooth polished surface, or at least a very subtle only realistic casting look to it?

 

im not saying this isn't possible because I think this technology has a big big promise for the future; I am just saying in my experience I haven't seen really nice small scale detailed parts, particularly not in person where it is easier to judge exactly what it is you are looking at.

This should pretty well satisfy your doubt. The prints in these vidios are untouched and are exactly as you see them when they come off the printer. These printers are just now starting to show up in numbers. They work entirely different than the fff and fdm printers.  http://www.electrictv.com/?p=15143

This one I want to try to build over the summer-http://www.instructa...ter-3D-printer/  It has a build platform of 4" X4" X however high you make the x axis and a layer thickness of 100nm. That is the distance between your thumb and index finger pinched together. They print from the top down vertically instead of bottom up horizontally.  It should rum me about $1k. Enjoy. This is how the technology is growing, not these cheap knock offs listed in this thread.

Anybody want to stay current with the developing tech here? It's only a click away.

This morning, a supply rocket was sent to the International Space Station carrying a 3D printer so they could make replacement parts.

I thought maybe one of the astronauts read the thread about the custom VW body and wanted to print it!

Actually, it was sent up to evaluate the functionality of the current technology in zero-gee, and to get an idea if making printed parts in space might be a viable goal for the future.

 

The supply ship is run by SpaceX, Elon Musk's (paypal, Tesla) company.

Sorry for the lack of detail. I must have been watching FoxNews.

I didn't mean to be a smartazz, belittling, or acting superior (as I've been recently labeled). 

 

I just thought it was relevant to mention this tech isn't actually being implemented at this point; it's only in the test-and-evaluate phase.

 

It IS kind of a big deal that the testing is starting, and that a toughened machine has been developed for the space environment. Thanks for bringing it to our attention.

they will be great for printing out screwdrivers and stuff. maybe specialized parts for the station or satelites.

 

just not in 1/24 scale!  B)

Came across this today, desktop for $799, resolution down to .1mm with built in scanner.  Resolution not there yet but we're getting closer all the time!

If I could go today, the screen door wouldn't hit me on the way out.
