[Software] FreeForm

Aloha, Here is a little about “FreeForm”. It is a new way
of modeling, using a force feed back device, to actually model in
digital clay. Introducing the FreeForm� modeling system� . . . the
first tool that lets sculptors and designers use their sense of touch
while modeling on the computer. It�s as intuitive and expressive as
physical modeling with clay or foam, yet with all the productivity
advantages of a completely digital tool. FreeForm lets you model the
way you want to, without constraints on your creativity. Feel the
difference For years software vendors have talked about “sculpting"
metaphors and “clay-like” ease-of-use. But the key element that makes
such an intimate relationship with digital forms possible has always
been missing: the sense of touch. They might as well have been asking
a musician to perform with earplugs or a painter to work blindfolded.
Finally, this compelling vision of digital modeling has arrived.
FreeForm modeling�s powerful 3D Touch technology channels creative
inspiration and intent directly into digital form. Modelers are no
longer constrained by flat interaction through a 2D mouse.
Inspiration is no longer filtered through layers of controls,
sliders, and settings. The creative impulse translates directly from
mind into matter. The digital advantage The FreeForm system brings the
power and flexibility of digital tools to physical modeling. FreeForm
"digital clay” does for clay and foam modeling what the word
processor did for typing. Copy and reuse model features. Control clay
hardness and surface smoothness with the touch of a button. Import
sketches to guide wire cuts. Mirror and scale features let you do in
seconds what used to take hours. Be daring - if you make a mistake,
“undo” is always just a keystroke away. Workflow that fits the entire
creation process The FreeForm modeling system fits comfortably into
today’s product and content creation processes. It bridges the gap
between 2D “sketching” and 3D production work. It can either
supplement or replace physical modeling, allowing users to create and
explore form in 3D as freely and intuitively as they can in 2D with
pencil and paper. You can import and work from conceptual sketches,
2D drawings, scanned models, or 3D engineered parts. Work quickly and
freely to rough out the model and explore ideas. Then, refine the
model and add details. Finished FreeForm models can then easily be
fabricated using rapid prototyping machines or exported to other
software packages for production. FreeForm benefits The FreeForm
system’s new approach to modeling: Destroys the learning curve: direct
model interaction and familiar tools eliminate the months-long
learning curve typically needed to master 3D modeling software.
Constant practice is no longer required for modelers to maintain
their effectiveness. Offers unlimited expression: FreeForm modeling
captures the flexibility and expressiveness of clay, and eliminates
the need to worry about geometry while modeling. Go ahead and tackle
those projects you wouldn�t dare try on the computer before now.
Speeds development: until now, the well-known productivity benefits
of digital tools have come at the cost of expressiveness,
flexibility, and training cost. The FreeForm system lets you have
your cake and eat it, too.

Upon creating an object, it can be manufactured using rapid
prototyping technologies (Sanders, CNC Milling or sent to a service
bureau). Isn’t technology wonderful?

We have been using satincast 20 for over 25 years with good results.
However, for the last several years it’s mechanical strength has not
been up to the task of holding the fine, deep detail we can generate
with our homemade CAM system. We use a centrifugal casting machine at
the slowest speed possible to lower the force of the onrushing metal
in to the mold. Careful sprueing helps but investment breaking down
inside the mold at the most delicate areas (often near the sprues)
keeps us from using the full wax carving capabilities of our system.
Has anybody else had similar problems and found an investment material
that is stronger? Thanks, John — John Winters

So where do you get it and how much does it cost? How much computer
do you need to run it? And what are we talking about cost-wise for
CNC machining or whatever ?

Hi John. Have you tried using the 38/100 ratio on the Kerr
investment…or the R&R investment. Kerr also has a fiber investment
(satincast with fiber) for extra strength which might work well for
you.We typicaly cast our high detail schoolrings on a simple vacuum
casting machine and achieve great ,porosity free castings in silver
and in gold.We also use alooys from united precious metals that work
very well with vacuum casting techniques. Hope this helps. Daniel
