Very interesting!! Have a look!

Hello!
Thank you so much for posting this! For me this is an extremely exciting thing since hair was the reason I postponed scanning for regular consumers.
Best, Magnus.

I know it is a pain to scan print the hair, but I dont think it is that hard, it just means you have to do a little more work on the sculpting side. For sure this new tech will make it easier for us but I don't see it as a reason to stop scanning?
Magnus, where you scanning for making the small figurines or for more professional work on TV or movies? I see that for TV and high end stuff you would need better quality scanning.

Hello Leo!
The reason was that we had intended not to print in Color Sandstone but print the heads without color in the highest quality we could (we were looking at the Envisiontec printers among others). So we would have needed the hair to look very good and look like it was sculptured. This turned out to be very expensive to get done (several 100s of dollars per hairdo), or if we would do it too timeconsuming, so we abandoned the idea.
Best, Magnus.
-
Hi Magnus, I see, yes for something of that level of quality it could be very difficult and time consuming :(
Well maybe with this new tech you will be able to get back into doing it :)

Hello Leo!
Yes I will follow this with great interest, hehe.
Here is an example btw of what we had in mind https://www.dropbox.com/s/hdp0n7lbywmwadv/140820_Print_Example_01.jpg (https://www.dropbox.com/s/hdp0n7lbywmwadv/140820_Print_Example_01.jpg)
This was just a testsample and is not the best quality though (Frosted Ultra Detail from Shapeways).
Best, Magnus.
-
Nice!, I wish we could do that much detail with full colors :) Even though we are not too far, I am sure that soon we will have machines that can print that quality with full color spectrum.
Leo
-
Cool Magnus!! I remember your face :D
Hi Both, Shapeways has just released full color plastic (I guess it is 4500) for pilot run. It seems it can print higher details than sandstone. Let me try to print a sample and report the result. :)
-
Hi meshmixup, isn't it that the 4500 prints lots of colors but it doenst have gradients? That what I heard.
But yes please do a sample and let us know :)
Leo
-
It can have gradients, but there is no real black... so it is NOT a full color :)

This 3D artist has tried to print his work on 4500. I don't think this can be easily made on sandstone :o

-
AHHH!!!! I want that machine!! Now I see that it really can do gradients. I dont know why some other people were saying that it could not. And it can do thinner pieces without breaking.
Interesting, thanks!
-
the color may look different (as Eric Van Straten is saying)
and this is from 3D Systems site
http://www.3ders.org/articles/20131202-3d-systems-announces-continuous-tone-full-color-projet-4500-3d-printer.html
Specifications and features:
Resolution: 600 x 600 DPI
Color: Continuous CMY
So as I said, no real black is possible, but only approaching it..
Price is around USD$69,000

I agree and guess that 4500 is pathing the way to next generation 6500 with CMYK ;)
-
I ordered two samples from 3D Systems, one of them was 4500 and other was the 660 sandstone. You can't compare the quality between the two... The colour is noticeably better on the 660.
-
Hi ttoke,
Can you share some photos of these two samples? Thanks ;D
Jim
-
Now it makes me wonder why they made that new machine with only CMY.... and no B... there must be a reason though.. :)
f/
-
Of course the reason is "business" and "money". Why sell the best right away when you can first sell something half as good while there is no competition, and wait to sell the better one later.
Unfortunately that applies to everything in life. Cars are that way also and so are tons of other things we constantly buy. :(
Foodman, I know you knew that and were being sarcastic but I needed to vent a little because I never liked that philosophy :(
Leo
-
Actually the 4500 model looks better on the pictures, the difference is even bigger in real life.
EDIT: Wow, the pictures are sooo big!
-
Hi ttoke,
Many thanks. Just to make sure which one is 660? 4500? ::) the darker one is 660 I guess
What is the size of this model? Thanks.
-
Hi ttoke,

What is the size of this model? Thanks.
Darker and sharper. ;)
15cm

WOW!, the colors on the 4500 are pretty bad. They look discolored or like the colors are running.
Could that be also the fact that since it is a new machine, they do not know how to calibrate it correctly or something similar?
I can get better colors than that with our Z450!

well as I said twice already, this is the result of a CMY ONLY print... so off course it looks like shit when printing a photo.. it is intended more for an industrial use atm.. although yes I am sure they still have quiet a few 660 to sell.. so they purposely omitted the black color.. when they will run out of 660 machines, they will "re-add" the black to the 4500.. and then it will look nice... voila.

I am sorry Foodman but I wlll have to disagree on that statement. Yes the full CMYK looks better, there is no discussion there but the CMY system can be made to look pretty decent too.
Look at this sample from our Z450 that as most already know is only CMY.
(http://i234.photobucket.com/albums/ee191/pinimodulo/Greal.jpg)
I know that those pictures from the 4500 were plain pictures and the lighting is not as good but you can still see that the colors are very crappy and uneven. That's why I wondered if they had to calibrate something that they didn't do right?
Leo
-
hey Leo
thanks for the photo... well yes indeed that model looks pretty good.. but that's sandstone ... the 4500 is another tech... so what comes nice from Sandstone is maybe harder to get on a 4500 with only CMY..
BUT it can also be the case that the 4500 needed to be calibrated better, so you're maybe right too.. who knows..
(nice model btw Leo 8) )

Hello again guys!
Just thought I'd show this example which should give another hint as to what I was working on.
https://www.dropbox.com/s/wxvxeyrr8kontxw/140823_Print_Example_01.jpg (https://www.dropbox.com/s/wxvxeyrr8kontxw/140823_Print_Example_01.jpg)
Those heads beside mine are 1/6th scale heads (not made by me ofcourse, the man is from a DiD figure and the girl is by Kumik), there is a big community around sixthscale collectible figures (just do a image search on Google for "sixth scale").
I was going to have the heads 3D printed and handpainted just like those are. That would have used the amazing quality that can be gotten from photogrammetry and given it a nice artistic touch from the manual painting.
I still intend to pursue that idea later since I do think it has merit especially if hair can be solved, hehe.
Best, Magnus.
-
wow.. thanks for the link Magnus ! These are indeed totally awesome..
I searched for 1/6 scale head models as you said.. and stumble on that one...
(http://i.imgur.com/wQptf.jpg)
-
Wow! Those things are crazy nice! One day we will be able to print heads like those already with colors and textures that amazing :)
Leo
-
Good inspiration 8), But I don't think the current resolution of printer can meet this level of details. Also the sandstone texture requires loads of work to refine the surface. :D
-
About the 4500 - this is not the only sample we have ordered, so I can assure You that the quality is similar on all of them. The colours tend to "bleed" more than on sandstone for sure.
The sample is ordered from 3D Systems, so I don't think it can be a calibration problem.
-
I have no expectation on 4500 any more :-[.
Thanks ttoke for your information :)
-
No problem. ;)

Its good to know someone is working on color print with different technologies. I wish I can print metal parts and color print my pets in house in my life time ;D
-
color print my pets in house in my life time ;D
Well come to Seattle and I can do it for you :)

Thanks for your invitation. I think even stoke light is too exciting to my 18 yr old cat ::)
Few days ago, a desktop SLS printer was announced. It is more exciting than color cubejet 8)

The price of Form1 can buy a full color 3D printer having a man height 170cm and weight 75kg!! :o
-
Well... I will have to see that machine working because form the pictures, the colors seem to be pretty weird, there seems to be some bleeding, mixing, etc. The quality also doesn't look too good overall.
One interesting thing I saw was that when it was printing, it didn't fill the bed completely with powder and that is nice so that you don't have to wait extra time for no reason.
Strange also that they chose to shoot the video when the machine was all messy inside :)
And the resolution they are claiming, 9600 by 2400 dpi ??? The Zcorp Z650 has a resolution of 600 by 540 dpi. Are they talking about the total resolution so the dpi multiplied by the build size? That seems to be the case.
I am sure that soon many new Full color machines are going to start popping out everywhere.

Hi Leo,
I don't think the print head resolution on 2D paper can be truly applied on 3D. I remember someone said the resolution of z printer is somewhat equivalent to 50dpi. Unless someone can improve the "effective" resolution of the powder, the texture detail cannot be improved further.
But 3000 dollars to buy a color 3D printer with 75kg is still amazing to me. ;D
