Foam For An Armature For Bronze Sculpture
I am so excited to have my foam pieces created by Synappsys Digital Services so that it will expedite my process of creating the sculpture of Evelyn Rubenstein for the Evelyn Rubenstein Jewish Community Center. There is still some work to do on the foam before I can cover it with clay. I can revise the piece and create deeper cuts into the sculpture. This give the sculpture depth. I love the sweater that Evelyn is wearing in this piece and I can hardly wait to put the texture into it in the end, but that is a long way off.

My Recent Sculpture Is In Pieces
If you have been following this blog on the Evelyn Rubenstein Poject you have seen how the 3d image was created in the computer and then sent to Synappsys Digital Service for milling. This gives me my armature. However the foam armature comes to me in pieces. Now I must put these together. I do this using Spray foam and secure the pieces with skewers. Some pieces I might not put together yet, such as the arms/hands. I may want to play with their placement a bit after the clay is put on the armature.
It is good to keep the foam away from the edges.
However, I feel confident in putting together the skirt with the bodice and I can begin to see how she is coming together. The hands are very fragile and I also attach broken fingers and sand the foam. We are a long way from completing the sculpture, but I’m excited to get my hands dirty and I look forward to meeting Evelyn in the process.
This time they are glued with foundry wax.

My Armature Is Delivered To My Door
Love when an armature is made for me.
I had been away and out of the studio for a week and while gone I was happy to see that Synappsys Digital Services, took the digital work that I had done and created and milled out my pieces. Here is a bit of technical information for any artists seeing this blog post. Synappsys has two CNC milling machines, a 21inch z axis, and a custom one that they designed and built— a 3 axis- with a 8′ rotary axis. besides milling Synappsys Digital Services, offers 3d rapid prototyping. They are in Norman Oklamoma which does not pose that much of a problem for me as a Texas artist as I can send them my files and foam pieces are light and will fit in a wardrobe box.
The process
Foam is put on the milling machine and the machine mills out the digital file that I have sent to them. The entire reason for this process is that it saves me time in creating an armature. I also can figure out some details of the process, and design which has been discussed in previous posts.

I Was a Non Traditional Student! Graduating With A Masters At My Age?
I have been a nontraditional student for quite some time now. I went to Vermont College to finish an undergraduate degree when my own child was going to college. I loved their form of progressive education. Then I went to Goddard College for my a Masters of Fine Arts in Interdisciplinary Arts degree. I’m graduating on Sunday!
This was not something I had to do, but something I wanted to do. It was a very fullfilling and wonderful journey.
Both of these schools are very different then your traditional education. Designing your own study was fascinating and a perfect fit for me. I am thrilled to graduate with my Masters of Fine Arts with both a focus in sculpture, especially as it pertains to digital technology in the studio, and writing.
On superbowl Sunday I will be making a huge touchdown, but it won’t be in sports.
For those interested, I was interviewed on our podcast by my daughter concerning this entire process. Here is a link for the podcast. Just click and the podcast will come up in your browser.
For those of you considering such a challenge, I have documented my entire process from undergraduate school to graduate school on my Perpetual Learner blog. Read my process, struggles, concerns and achievements. It seems strange to think, that way back when i was applying I was first figuring out how to find out what shots I had in high school.
Remembering When…
Many years ago Houston PBS came to my studio and created this documentary on me and my artwork. It won an award. I have always wanted to put these up on the web but never had time, slowly I will add more of the tv media coverage. Until then… here is
Making a living while living a dream.
Exporting ZBrush File For Milling
I have been on the phone with Synappsys Digital Services trying to figure out the best file, size and format that my digital sculpture of Evelyn needs to be in for them to work. This sculpture was created in the computer, will be milled out in foam and then created as a life size bronze. Synappsys Digital Services will be milling this out for me, but first I need to get them the file.
I have already decimated the individual files, with Decimation Master in ZBrush and I talk about this in a previous post. An important thing to remember is that ZBrush can create some very large files. Many companies that create output, for either milling or digital printing may not have the capability to handle such high resolution meshes. I have spoken to Synappsys Digital Services and they can handle 5 million or less.
To upload the file I have called Synappsys Digital Services and asked them to provide server information to upload my files. I must be able to upload them via Ftp. I use Fetch on my mac, which works just fine. With my FTP information ready, now all I need is the proper type of files.
Synappsys Digital Services can work with many different types of files. They can work with obj’s but their file of preference is STL Binary.
of all of my
subtools I can
merge them
down to create
one tool that
has all of its parts.
Obtaining OBJ’s are simple. While your Z tool or sub tool is selected go to Export and several file formats are available in the drop down menu. I need to export this sculpture in 4 pieces-both arms, the body , and the base. I will also want to combine the pieces and send it as one file. This way Synappsys Digital Services can see how each piece goes together. The reason why I want to separate the pieces is that if I combined all of them I will lose part of her hand as I realize that as it is placed on the digital sculpture the thumb is inside her body. I want to work with these hands more closely once I have them enlarged and sculpted. I need them separate and I need a thumb. They may also be milled at a different percentage to the rest of the body. They are more defined and so the hand/arm will probably only receive a minimum of clay on top.
Where as, the rest of the sculpture needs work.
To get an obj of all of my pieces I simply duplicated all of my subtools and then merged down these duplicated subtools together as one tool. Now I have both the subtools apart and one piece put together.
I have exported each an uploaded them up to Synappsys Digital Services but let’s see how the 3d Print Exporter plugin works in ZBrush.
Preparing ZBrush File For Digital Milling
I have worked diligently with this model. For ZBrush users or traditional sculptors entering the digital field, here are some things that I had to do near the end.
Perspective
Be sure that I was viewing this entire project in the perspective view. We traditional sculptors are not used to having to push a button to see in perspective, but these digital programs do. This should be done in the beginning to be sure you are sculpting correctly. This is basic, but check before you output.
Will my cut foam pieces align?
I had to fix the arms, as mentioned in the previous post. I need to fit these arms on the body and they will be milled at a higher resolution. I also plan to use less clay on them. I had sculpted them way under the sweater, instead I cut them off at the sleeve. I did this using Transparency to see through the sleeve.
Preparing Files
I will be sending this as 4 separate files- the base, the body, and the two individual arms. I might also combine them and send them as one file so that Synappsys can see how they go together. Though I do want them milled separately.
Before I can get these pieces ready there is another step I must do. Right now the files are very large for each. ZBrush has something called Decimation Master. Decimation master lets you hold your detail, but brings the file of each of the pieces down considerably
For example:
Before Decimation Master After Decimation Master
34% OF DECIMATION)
Right Arm
Active points 326,954 127,188
Left Arm
Active points 296,078 140,452
Body
Active points 7,751 mil 3,329mil 1,149 mil
Base
Active points 87,202 37,468
I can export the entire project and individual subtools, ie. arms, body and base as individual obj’s and then combine them as one obj . However, ZBrush also has a plugin that allows me to collect for output in the preferred .stl file for digital printing. Which means that I will have a different type of file for the vendor. In the next post I’ll talk about my experimentation with this plug in.
Ready To Send Sculpture For Enlargement
used as the armature f
or the life-size sculpture.
I have been working hard, looking at reference and learning about my new subject—Evelyn Rubenstein. I am documenting this process on a blog created for the Evelyn Rubenstein Sculpture for the Evelyn Rubenstein Jewish Community Center. I’m also posting some more detailed, technical information on my own Creative Endeavors blog. I have been using some of the new tools in Zbrush. Such things as Dynamesh which made my work much easier. The final sculpture will be milled in foam by Digital Sculpture Enlargement and Reduction and then sent to me. I will put clay on the foam and finish detail so that it can go through the bronze process. I thought I would give you a little 3 dimensional tour of this new piece before finalizing it for output.
Working On Preparing An Armature
I have been using zBrush to create an armature to send to Synappsys Digital Services for milling.
This is similar to what I wrote about in Digital Sculpting With Mudbox: Essential Tools and techniques for Artists, and what I have done with the panther project; however, I feel I’m pushing the process a bit more.
Here is the digital sculpture almost ready for the milling process. I believe I am going to send it to them but would like to separate the arms from the sculpture. The reason for this is that in the digital sculpture if the hands are sent with the body as one file they get lost in the clothing. I would like to determine their placement without losing details. Synappsys will separate them anyway within the process of getting the pieces ready for milling.
I’m not sure what will happen with the pearls. I doubt these can be done, and might actually be better for me to sculpt them on her. In fact, I’m leaning in that direction. Having them on the sculpture while working digitally has helped me with size and proportions. I have a few more things to do to the sculpture, and am anxious to hear what Synappsys thinks.
I SPOKE WITH SYNAPPSYS
Here are some of the things we discussed. As mentioned in my previous post, this Dynamesh is acting similarly to what Synappsys’ program will do when it lowers resolution. I have been requesting that Synappsys to mill out several heads that show either different resolutions of milling or different reductions. I am hoping to include this in my up and coming book, 3D 2012 digital art in a physical form. This will be a very important visual for artists to understand this entire process.
Some thoughts as Synappsys and I spoke
- The arms are created as what zbrush calls a “sub tool” I can separate them for milling , but I should probably be sure that they are cut and align evenly with the arms. Presently they sit within the sleeve. If they are a clean cut, and can match up, preferably somewhere in the arm where the sweater is, where I will have more design wiggle room, that will be better.
- It is almost paralyzing to try and figure out what size to mill this out at. There are several variables. If I want to add a lot of clay in the traditional studio , I have to allow for that mass. This may mean that I want to reduce the size. I may want to add little clay to the arms and hands, and up to 1″+ amount of clay to areas like the sweater, skirt, hair etc. So, I might have the pieces milled at different sizes.
- But the size problems don’t end with milling. In the traditional process of bronze casting of a life size person, it is known that artwork shrinks. My foundry indicates that I could lose up to an inch in size. But often times, the foundry can make this up as they are welding the many pieces together. Another aspect of casting in bronze is that “some pieces can shrink in the center, or look skinnier,” says Scot Yoast of Art Foundry Houston.
The entire concept is frustrating for an artist who goes through great lengths to sculpt a perfect or near perfect sculpture and have such deformations. My heart gets excited when I think about how digital processes are infiltrating the lost wax method of bronze casting and how this will change in the near future. A subject that I have discussed quite often on this blog, and I will go into great detail in my new book For now, I’m having to work this tra-digi art in any way that I can to get the results I desire.
ZBrush And Dynamesh
this photograph for a better view of resolution.
As I prepare a digital model in the computer that will be enlarged and milled in foam by Synappsys Digital Services I am playing with settings. At this point the sculpture is in Zbrush and I’m working on creating the mass where I want it. I want to do a mjority of my sculpting in the traditional clay, and not have it totally milled in foam in great detail.
I like being able to spend time on the body shape and head shape and flip it around in my computer, comparing my phtogoraphic referece to the shape I’m creating in the computer. This is much easier than standing on my head downstairs in the traditional sculpture studio.
I’m also playing with a new feature in zbrush called Dynamesh. I have mentioned this elsewhere on this blog. Dynamesh is a button that remeshes the entire sculpture to fix any problems with the mesh. It is a good thing to have, but because it is new, I’m trying to learn how to use it.
Double click on the photo on the right and you will see the top photo is my head in the original, the second from top remeshes using Dynamesh at 648 resolution, the next at 904 and the last at 1024 the highest setting. I’m wondering if this is what is done at Synappsys. It is hard for an artist to visualize how much of their form will not show up depending on the resolution and the size they ask Synappsys to mill in.
If you are interested in reading more about Dynamesh at Pixlogic- here is a link
HAIR using new tools
Another new tool in zbrush is a curve tube. I wondered If I could use this curve tool along with Dynamesh to get a better form for my subjects hair. Seems like it will be highly possible, if I want my sculpture remeshed. Here is an example of using curve tube and dynamesh. Notice
you have control the tube while it has the dotted line, then simply smooth it into the hair once it has been added to the original mesh with Dynamesh.
