Description

Akiko is a Poser character model adapted to a solid figurine and made printable without added support on an FDM printer, such as the MBI Replicator.

Printable Figurine: Travis Driscoll (aka:leadingzer0)
Poser Character: Akiko by Joe Bushido @ renderosity.com/mod/bcs/akiko-by-joe-bushido/64939
Base Model: Victoria 4.2 by Daz @ daz3d.com/shop/victoria-4-2-base

Daz's Victoria 4.2 mesh required.

She would make a good benchmark print. There's more detail not realized at a layer height of 0.1mm and as well as a range of overhanging features.

Yes, she is clothed.

Also, she's impossibly awesome.

I would hate to be rewarded for putting my work up for free with a lawsuit from the copyright owner of the template model. It would have been my preference to post the .stl, simply. I'm glad you were able to print it. Post a pic, eh?
isn't too hard to figure out how to get this printed, google is your friend (when it comes to looking for the seed file that's mentioned in the instructions but 'missing' (not included here), then using a the greentoken online 3d model converter to convert the resulting file to an stl
Thanks for the good tip about MakeHuman!

Instructions

The .stl for Printable Akiko can be derived using Objaction Mover on the .pcf that I have provided and the .obj of Daz's Victoria 4.2 Base model, which you must have or must acquire.

We have to go round-about this way to avoid violating the copyright on the Victoria 4.2 Base model. I cannot post the raw .stl directly on Thingiverse because it was derived in part from Victoria, and the TOU forbids distributing derivative meshes. But the differences against the Victoria 4.2 .obj (the .pcf) can be distributed. This technique has been in use in the Poser community for quite some time to Daz' satisfaction. Many thanks to Ratteler for pointing this technique out, otherwise the model would have had to be removed from Thingiverse entirely.

EXTRACTING THE MESH akikoC160recons.obj -> .stl:

VICTORIA 4.2: You need the popular "Victoria 4.2 Base" model from Daz. It was free or offered at a steeply discounted price for a long time, and I believe it was also bundled with Daz Studio 3, which was free. Currently, though, it appears to be available for $15 at daz3d.com/shop/victoria-4-2-base . If someone discovers a more affordable but legitimate price/source, please post.

The specific file within Victoria 4.2 that you'll need is blMilWom_v4b.obj which usually can be found under the relative path from the install Runtime/Geometries/DAZPeople with a size of 7795 Kb with an Md5sum of b39dbf15c1c11af69ec53d05eb999aca.

OBJACTION MOVER: An ancient but functional (Windows) program available at @ mystic-nights.com/freebies/details.php?image_id=319 . I've also attached it, since apparently it's allowed.

EXTRACTION AND LOADING:
1. Launch Objaction Mover
2. Click on the "Decode" radio button
3. Enter the location to your blMilWom_v4b.obj into the "Seed File" field
4. Enter the location of akikoC160recons.pcf in the "Difference File" field.
5. Click "Convert"
6. You should find akikoC160recons.obj alongside the .pcf.
7. In ReplicatorG, click File->Open
8. In the "Files of Type" pulldown, select "OBJ files (experimental)"
9. Find akikoC160recons.obj and click open.
10. Be sure to click Move->Put on platform, since the base is slightly buried by default.
11. Save out the .stl, compute .gcode and print.
(but also attached)

PRINTING:

A challenging print, but worthwhile. It took me a number of tries before I worked out the issues. If your having issues, post _details_ so I can work with you and revise the model if needed. If it prints great, post so there won't only be complaints in the comments. ^_^

There are two challenges with this, and it's useful to address them separately:
1. (0.1mm) printing akiko at 0.1mm
2. (akiko) printing akiko

If you don't have experience printing at sub-default layer heights, I would recommend recomputing the gcode with a default layer height. She still looks great at a lower resolution, and you come into fewer issues.

I printed Akiko on an MBI Replicator in white PLA with a layer height of 0.1mm, using ReplicatorG 34 and Skeinforge 47. No raft or skeinforge supplied internal/external support was used. I used 90% of available build height, so the final print measured 5.25". The resulting un-refinished print is pictured.

I have also successfully printed her with the default layer height of 0.27mm at about 2.5" (~8cm) high without doing anything special. Still, this should be challenging print.

The .stl has included support for the legs which is to be twisted or clipped off after printing. The hilt of the right sword is somewhat fragile, so take care with it. I may revise it.



Skeinforge Settings:

- (akiko) Skeinforge v47
- (akiko) Craft->Dimension->"restart extra distance (mm)"=0 : With default Skeinforge settings, some details may be omitted. Create a profile for detail prints such as these which has If you see that the leg supports are not attaching or the swords are not printing right, this is your problem.
- (0.1mm) Craft->Fill->"solid surface thickness (layers)"=5 : If you have a layer height less than default and the print is breaking midway, you'll want to increase this to 5 or more to add strength on the flat surfaces, specifically the stand that the feet attach to.
- (0.1mm) Shells = 1. Adding more shells will increase strength, but will increase the print time and change the cooling. Start with 1 before you try beefing up the print. If there is breakage, it's usually because the head snagged on a curled-up feature rather than that the print is too weak.

Skeinforge will gripe about some shapes when computing the gcode. These are very small features that don't correspond to problem areas in the final print.

Model:
I posed and modeled her so it would be printable with FDM, building in bottom-up support and redundancy. There were many iterations of printing and fixing issues in the model, but some potential problem spots remain:
Known weak points (may revise if too may issues caused):
- (0.1mm) where the right foot attaches to the stand
- (akiko) where the left hilt attaches to the hand
- (0.1mm) the model being pulled over backward by the print head
Overhangs that will likely require touchups after printing:
- bottom-most point of handguards of sword
- scabbard attach straps, rear, base
- tip of nose and chin
- crotch
The Face: a lot of people are having trouble printing the face cleanly. In PLA, I was able to get good face prints with aggressive cooling.

PLA instructions:

(0.1mm) Cooling:

If printed in PLA at a sub-default layer height, cooling is vital. I have a small squirrel-cage fan that I've turned on its side so that it blows a plane of air across the nozzle and newly laid filament, from the side of the print. The fan setup is pictured in a comment below.

Signs that your cooling isn't adequate or you need to adjust nozzle temp:
-printhead endpoints accumulate plastic, which curls up into future layer territory, and the printer snags on it later and pulls of the print.
-her facical features are ozzed, leaving her looking like a burn victim.

Thanks for the links. I've been learning a lot over the last month since I got my printer. I've taken a crash course in at least 3 3D programs (Daz, Blender and Sculptris), and I'm finally getting to play with some of the models I've acquired over the years.

Reading over Daz's terms of use for their figures, it's plain that they didn't think of 3D printing when they initially wrote it. (It may have changed recently, most of my models are old, V3 or older) As long as I sell or give away the finished product (ie. the actual plastic printed model) but not the files I created to print it, it is no different than if I was taking .jpgs of the models and putting them on the internet.

Granted, that means I can't put up any .stl files, but I can make models, game miniatures, or action figures to give to my friends. I've thought of using the models I plan on printing to use in lost wax casting for bronze and aluminum. Again, as long as I follow the terms of use for creating the art (and make sure that the parts I use for my models are allowed commercial or unrestricted use) and keep the files to myself, I can do whatever I want with the finished product.

Also, I found a way to quickly clean up a posed figure. It only requires a 700$ program called Zbrush. *sigh* That cost more than my printer.
Btw, is the zbrush process simply import-compute-export, or is there a lot of manual work involved? I might look into it.
Google videos of Dynamesh. it is an auto retopolizer. From what I've seen it will merge all the parts of a model into a single mesh. You lose a little detail but it looks like stuff the printer will lose anyway. I have a friend online who does 3d stuff, I'm waiting to see if he has Zbrush and is willing to reprocess stuff for me.
Hm. $700 vs. 100+ hours for the first part, 20+ hours per part thereafter.

Daz's models are very good. Having since studied parameterized character modeling since, I've come to appreciate their quality.

A really good alternate, free license model source is "MakeHuman". You can parmaeterize in their app, export the model and rig to blender, then pose and modify in blender. The models are lower poly (good), but not quite as versitile as Daz models (less good).

Having worked with Rigged models in blender, I haven't gone back to Poser in a very long time. It's so much easier to pose, ironically.

I spoke to Daz about updating their ToU to accommodate 3d printing a year ago. Not interested. Too many worms in the can. Perhaps they'll reconsider when 3d printers are a common household appliance. But then, by then, model sharing may be restricted even further by other powers that loom... the modern bourgeoisie-- to be all Marxist about it.
Thanks for the good tip about MakeHuman!
Any tips for clean up on a poser figure? Trying to get the hair, clothes, and props to work together is making me pull my hair. I can export to obj easy enough but things like the eyes, teeth, and other 'hidden' parts still exist inside the mesh. I've thought of re-topping it in blender but that would be extremely time consuming and I'm still learning how to use the infernal program. If only there was some way to put a thin skin over the outer surface of the model then delete everything inside it or solidify it. Also I belive Slic3r just hates faces, I have yet to have a decent print of any face.
(read replies in reverse order. excuse grammar.)
Also, faces:

We're dealing with a medum in its infancy, so you have to play some old-fashioned tricks. Think theater/1920's silent move-makeup, exaggerating contrast and detail so that the distant viewer perceives the details. Think bronze/marble busts, with the pupils carved deep to create the illusion of shadow.

Both the slicer and printer conspire against you. The slicer will approximate out critical features. The printer will gush plastic on the details, especially as the print winds down, and especially if your character is facing downward.

Tilting its head back will help. For akiko, I compensated with agressive cooling and control. I really like her leveled gaze, but if I did it again, I would probably find a way to make it work with her head tilted back for print-ability.

For the eyes, I drilled deep holes larger than the desired pupils to create shadows and force the slicer to take the curves. I exaggerated the nose so it would get that characteristic crook and point that I was looking for.I think the brow also required some work. Otherwise, it was all flattened out and/or smeared together. The plastic would fill in the eyes, and the bottom of the nose would be cut off.

And, of course, you need to support all your features from the bottom-up. Hence, the chin is supported by a lock of hair that curls across it.

My print was at 0.1mm, which was quite aggressive for the time. Even then, I had to really shout the details to make them show at all.
Tacking a Poser figure is daunting. It was my 3rd print project, and sorta burned me out. It would be much easier if you got a thorough understanding of blender before you started, but then, if I had, I probably wouldn't have never attempted it.

With akiko, I didn't retopo and I regret it. It will take quite some time to retopo your figure, but probably less than dealing with the glitches and bugs that come as a result of trying to shoehorn the full res mesh into something that's printable. Also, the result will be easier for the slicer to understand.

What I did do with Akiko worked, but was an infuriating head bashing litany that lasted countless days. What you need to end up with is a single exterior solid shell. After several failed attempts to fix up a simplistic export, I exported each part separately, made each a solid, booleaned each into the final figure in turn, and between each boolean, fixed nonmanifold faces. I started from scratch on the hair, sculpting it in blender, and merging it in as well. When the boolen fails, it will just return garbage. There will always be nonmanifold faces, for no particular reason.
Here's me mid-throe, and a description of what worked...-ish.

blenderartists.org/forum/archive/index.php/t-253863.html?s=ee47acea1c5bbe7ef2ca49607c6bd91a

That was a year ago. Blender has since added 3d prining tools (in 2.67) and may have improved its boolean modifier (or may not have).

So I'd really recommend retopo. This is a good, free tutorial for blender: youtube.com/watch?v=icqPZnD_3lA
but if you're planning on learning blender, I strongly recommend dishing out $10/mo. for a citizen membership to cgcookie.com, even if just for a month. These guys are solid. Its far better than wading through all the tutorials on youtube/vimeo, 90% of which are crappy, outdated, incomplete and/or misleading.

Nothing can fix self-intersecting faces (sorta: I tricked sketchup into fixing them, but then I thew away the result because it introduced all sorts of other problems.) So, you have to remove those manually. At least now blender will identify them for you. You'll probably see a lot around the fingers and toes.

And, of course, don't use any Daz figures, ( about every other comment below). You won't be able to share them freely, and that would simply be a shame.

Truly, best wishes to you.
I usually export my poser characters into Rhino3D for use in renderings. If I convert the poser character saved as a 3dm file (Rhino format) to the zprint format for a ZCorp printer would that be a problem with Daz ?
Converting to a different format to print isn't a problem.

They would have a problem with you widely distributing any non-image derivative of the mesh. The contact that I spoke to at Daz was cool with me doing a 3D print, and even distributing the physical, printed result. I expect that would include passing the file to a service such as shapeways to have the 1-off print made... so long as it didn't end up available for download on the shapeways site.

That being said: I'm not affiliated with Daz in any way. I can't make legal statements on their behalf. I spoke to a sales rep at Daz about the rights that a V4.2 license buys me, specifically regarding 3d printing. He seemed sane and reasonable. That was about a year ago. He may not even work there anymore.

Could someone please send me the STL file? I don't have windows to install the program to convert it to an STL, only have a Mac. I would be very grateful for your help. Thanks.
i think we just need to use something like antonia 1.2 which is open source and better rigged than victoria4... then buy a module (9$) for wardrobe wizard (now included in poser 9/2012) to use any product from v4 with antonia...
Most of the work with Akiko was shoehorning her into a printable model. High poly modeling tools were made for rendering, and solids tools were made for low poly objects, and never the twain did meet. So many hours of cleanup, so many print iterations, so many blender bugs, and still there are a few intersecting polygons. Going back to poser would require an 80% redo. I... must resist... succumbing... to meme... ain't nobody got time for that.
But thanks. This is very useful. Perhaps the tools are better. If I decide to give it another go, it will definitely be with Antonia. I _so_ want to post an .STL and just be done with this copyright and windows-only objaction mover nonsense.
sry mate i rly want to print her but as soon as it starts slicing i get a message about looping faces and it wont slice, just wasted a whole afternoon to try to repair the mesh manually since the damn netfaab basic cant fix it ( only pro can grrrrr)

is there a way to get a fixed obj file or stl for this one

otherwise great job mate , shes gorgeous :)

keep it coming

Yes, this is a very high poly mesh and of the fine details, such as in the hands and nose, confuse things. Some programs, such as netfabb, don't like the edge ordering and have a hard time with the volume. I spent a many days on the mesh trying to reconcile this to no avail, and decided I was being academic and obsessive, esp. since RepG still printed it. The geometries of the issues are so small, they're immaterial in the final product.
If you want to try again, I'd focus on the slicing and not the mesh. There will be such warning messages, but it still slices and prints for me and others using ReplicatorG/skeinforge, in the least. You may try different scaling and slice resolutions, detail settings or possibly different versions or programs, if it comes to that.
Amazingly and totally printable ! Without supports. I made one with success. Minor bugs like crotch and oozing from leg to leg but otherwise it is a fantastic design. A friend is currently painting it.
Fantastic. Please post a pic!

A lot of effort went to make Akiko build base-upward, but there were some character-defining features which complicate the print that I wouldn't abandon, . The downward tilt of the head was necessary to project a focused gaze. But the inverted angles on the face proved messy for some, especially as the printer slowed for cooling but kept extruding at the same rate. It would have been easy to print if I tilted her head backward, but then she'd be far less intimidating, wouldn't she? Also, I wanted to portray her high-energy state, on her toes and leaning forward slightly, but that took several days to figure out how to do without her legs breaking off the base before they were joined at the hip.

The banner image of Akiko was of a print that I did in white PLA, but there was some finishing as well. The tip of the nose ran a bit, the lower hilt guards were largely unsupported and needed trimming, the eyelids drooped into the voids that make up the pupils, and there was some extrusion webbing between the legs, as you mentioned. I performed a cursory manual cleanup with an xacto-knife and a narrow shine-strap of 400-grit sandpaper.

The initial nude mockup had no problems with the crotch, as it built from the legs to the buttocks and forward. Adding undergarments introduced poorly supported inverted surfaces that result in a bit of loose extrusion. I went through a few iterations, but never quite got it clean. I finally reasoned that people won't be focusing too much attention there anyway.... which I think is a perfectly reasonable assumption, don't you?
hmm, I wonder, would it be okay to post gcode? Technically that's the same kind of finished product as a rendered image or video and can't be used to create any further derivative works, which I guess is the original point of the restriction: If you want to create original art, pay for the model.
I feel the same way.  I spoke to someone at Daz when I was trying to work out a way to distribute the .stl.  I made this specific point.  He pointed out that the 3d model could be reconstructed from the toolpath, and that they were not cool with that.
I didn't press the issue after that. Ultimately, I needed their written exception to their TOU to distribute the .stl and it was clear that I wasn't going to get it.
I'm glad I did find this established method, though it's unfortunate it cuts out mac users and people didn't get the V4.2 model while it was free or aren't in a position to pay for it.
So if I understand this correctly, there's no free way to pint this anymore?
Not unless you got v4.2 when it was free. I wager that Daz started charging for new downloads of v4.2 to push people toward its repacement, v5, which is free for now. I can't refit Akiko to v5.

They're thinking about CGI and not 3d printing. I can share and sell images and video that use v4, but in their minds, theres no valid reason for me to distribute derivative meshes. :-[
Thanks for getting the model back up. I have Daz3 (never used it).

If someone can place her on a different base, would it be ok to upload a derivative as an .STL file? or would that not be allowed in this case?
No. The same restriction applies. If that would do it, there would currently be an .stl up instead of a .pcf. Akiko is not recognizably Victoria4.2, which is merely a posable, parametric, textured, bald nude. I either have written permission to distribute from the Akiko character author or I personally made everything that differentiates this character from V4.2-- the body proportions, clothing, the gear, the hair, the stand. It's completely remeshed and reduced to an exterior shell. There's not much V4.2 in there in there. Even so, the copyright stands. This dramatically reduces the audience.

The attached Objaction mover also computes .pcfs, and is an established way to post derivatives of copyrighted material without including/violating it. If you make a derivative of Akiko, post a .pcf which is recomputed against the Victoria4.2 .obj using Objaction mover.

V4.2 was free for a very
long time, and I presumed it would remain so. This is a lesson in the difference between free (without cost) and free (without restriction).
thank you .. yes i have Daz 3

And 4 and V-4.2 etc. if i can print her i will but not having any PLA hope i can with abs.

well some PLA samples
ABS prints look decent, but I haven't seen the facial detail come through as of yet.
Looking forward to printing this one, when the model is back up.
Printed from the original (sadly unavailable at the moment) gcode, it is amazing. You must get the issues resolved and do more figures like this.
Printed at 45% on a prusa2, 225 degrees, 0.5mm nozzle, 0.2mm layer height, pretty pleased with how it turned out :) thanks :) This is why I always download interesting stls from thingiverse straight away :P
I assume unless our printer is exactly the same as yours then this file isn't any good.
You can get the Akiko mesh again, provided you have Daz's Victoria 4.2 mesh due to copyright.
