3D printing quality

[59 Buick]

Hello all,

3D printing is advancing in leaps and bounds, I have been following this progress with some interest and found this on armorama

These figures range from 1/72 to 1/32 scale and the level of detail is pretty amazing.

Wow!

That is most impressive! It sure would be cool to see this tech applied to 1/25th cars!

The possibilities are astounding.

thanks for posting this.

There is a massive 3D thread going already. Maybe the mods can combine this. I am always excited to 3D printing take the next step. Hopefully someday I can take my files to my local kinkos to print model parts, or even at home. It's inevitable. 

[GlueTube]

Amazing. I for one would like to know the make and model of the output printer as well as the output medium.

Sorry didn't check for the other thread and am more than happy to have this one added if that's possible

Those are impressive.

Probably printed with an Objet or similar machine that uses plastic goop as the material, as opposed to filament or the sand-like stuff.

I still question cost-effectiveness for larger-scale production for this as of now, but what's there is pretty good.

premium quality and cost effectiveness do not typically coexist.

Those do not look like they were printed on an Objet or an FDM (the melted plastic type) machine.

They look like SLA (pool of liquid) or SLS (box of sand) pieces.

At work we HAD and SLA (it cost 250K) and when it was retired it was replaced with an Objet. I have pruchased both FDM and SLS parts also.

The trick with many rapid prototype machines is support material (what hold a shape the juts out sideways as it is being made). The FDM uses a bulky scaffold matrix, the Objet uses a material similar to crumbly cheese, the SLA uses a delicate scaffold matrix and the SLS uses it's own sand (hard to explain). The only one where you can reach in an pull out a part and not have to remove support in SLS (removing support often destroys delicate details). There are some new hanging SLA builds and I do not know what they use or need ofr a support.

I would guess that they are SLS parts.

So I just looked at their site. I think they are castings mastered off of a rapid prototype. Nice looking work! Carmak

Nope. As Norbert explained:

"Reedoak will not cast, you will get directly the 3D print as they are shown above." 

"I'm afraid some of the details, like microphone, wires, lines, pocket details, etc...will not survive the casting process. So it was a choice not to cast and try to keep all small details that make the difference."

He also mentioned in another post that the printer is a type used to make jewelry. The tech savvy guys here can figure out the model.

[Ace-Garageguy]

The print files are translated directly from highly accurate laser scans of real people dressed in the period-correct gear. The prints are done directly from the translated scan files, so scale can be changed to whatever the client needs, instantly...these are NOT resin copies of 3D prints. Price, trimmed, is about $25 each. It will come down somewhat, but it takes time to do prints of this resolution. Time is money. A 20% discount is available to modelers who will trim their own pieces.

As printed, still having supporting structures...

Check out what Yaroslav, of Live Resin, does for weapons and gear. It's mindblowing. It doesn't get better than that. Still can't find even cast 1/24-25 figures and accessories, let alone 3D printed stuff, one tenth as good as what is available for 1/35. Wassup wi'dat, yo?

The 1/35 guys will pay what it takes to do it.

The car modeler complains about kit inaccuracies as much as the armor modeler. Considering that the cost of an armor kit is $50+, and a car kit goes for around 16-20 bucks, that Revellogram 19-Eleventythree Fleem-mobile Hardtop kit leaves a lot more in the buyer's pocket to use for AM than does a $79.99 Dragon Tunisian Tiger I for a treadhead modeler; yet, the latter will gladly spend twice the kit price in order to get the AM parts to "get it right". Go figure.

Get me the files and I'll print them. Just for fun, to see how my printer would do with a figure, I printed out a nude female standing erect on spiked high heal shoes. A little under 3 hours later she emerged from the resin vat with perfect detail and was an exact replica of the stl. file I used to print her. She is 48 mm in height with the heals on, which should be about 5' something in bare feet at 1:35. Unfortunately, do to the rulse of this forum, I can't post a picture. I printed her at 100 micron layer height. She would have come out even better if I could have printed at 50 micron, but I didn't want to wait 6 plus hours just to see how she would come out.

I'm looking at having a go at this as prices for the 3D Printers are falling quite well here in the UK.

I'd like to print car bodies and spares like racing seats, surfboards, beetle engines in either 1/24 or 1/25 scale. can you tell me if that is possible please?

I've cast the seats, and surfboards before in plaster to hope to go up a rung to resin but I have to mix such a volume to get the mix right that it's proving expensive.

Before you can even consider purchasing a 3d printer, you have to consider a few things. The big thing is the stl. files to print. Where are they going to come from? If they don't exist, do you have the ability to create them? If not, do you want to take the time to learn how to create them? The list goes on. I explain in this w.i.p. here http://www.modelcarsmag.com/forums/topic/101922-1935-lasalle-convertible-coupe-3d-printed-at-home-july-28/ some of what it takes to print model parts with a 3d printer. You will see the difference between printing with a fdm filament printer and  a high detail sla dlp printer. This model is being printed in 1:18. I explain why in the w.i.p. If you want to see 1:24 scale parts, go to this w.i.p.  http://www.modelcarsmag.com/forums/topic/104304-59-plymouth-vert-with-some-3d-printedparts-august-11/.

Check out the  1/4 scale "3D Printed" Model T Hot Rod.

I know the fellow who's doing those military figures.  He's using a rather inexpensive EnvisionTEC DLP resin machine (inexpensive compared to other industrial 3D printers, that is) that is normally used for jewelry and dental work.  The 3D printing is the easy part of what he's doing, though.  The real trick to his process is that instead of sculpting the figures, he's scanning real people, wearing the correct uniforms/outfits.  So the result is his figures are much more accurate and lifelike than any sculpted figure could ever be.  There are limitations, of course-- chiefly, the object you want to recreate has to exist in real life in some physical form or another.  A sculptor or designer can create a 3D model from nothing but his imagination, but the scanning process needs something tangible to start with.  Even with scanning the people to get the 3D model, there is still hours spent editing the 3D models for printing.  Scanning is not a "shake & bake" solution.

The printers will likely become as commonplace and inexpensive as desktop paper inkjet printers are today. I think the delay may come from the other end at least until some form of quick 3d scanner or other easy way of designing the prototype becomes available to those of us lacking design skills.

I tend to believe things will things will be a little different. A cottage industry much like resin casting will evolve. Printable part files will be available for purchase. It's already started. I have 2 Delaheye 135 Heller kits. I want to print out a F&F coach works body for the 135 & 165 roadster. I could create the files, or I could purchase the files already done from here:  http://www.cgtrader.com/3d-models/car/antique/delahaye-135m-figoni-and-falaschi-convertible-1937 and  http://www.cgtrader.com/3d-models/car/antique/delahaye-t165-1939. I have already checked and they fit my needs and save my a lot of time.

it has more on the Import aftermarket crowds and in the Donk model scene

It was meant as an example, Frank. By the way, congrads on the Form 1 purchase. I had the impression about a year ago that you were leaning toward making a purchase. Nice choice.

i had to get a refund my dog had a emergency surgery the form 1 people were very cool about it and sent him a get well card and treats
