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And don't forget, bumblebees can't fly (according to some outdated understandings of aerodynamics).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.
