Would you give a talk at my event or class?
How can I stay in touch?
Do you take commissions?
You used to have X for sale, when will it be back?
Can you make bigger glass pieces?
How do I clean your sculptures?
Will you help me make something?
How do I start making things like yours?
Can you recommend a course of study?
I'm writing a report, tell me something about what you do.
I'd like to use pictures of your work.
That's fine, as long as they're accompanied by my name ("Bathsheba
Grossman") and if they're online a link to this site.
If you need high-resolution images for printing, just ask, I have many that you can use.
If you'd like to use a 3D design for any purpose, please ask. I've licensed models for many uses, and I'll most likely be happy to
help with yours. I like to collaborate.
Don't reverse engineer
my 3D designs without permission. Doing this violates
copyright law, makes me unwilling to work with you in future, and is weak.
Talk to me, most likely we can do what you want as an authorized use that will make everyone look good and
feel happy. I'm
nearly always pleased for my designs to be used and adapted, if you get in touch first.
Would you give a talk at my event or class?
It's fine to ask and sometimes I can do this, but I hope you won't take it personally if I decline.
Public speaking is difficult for me and I accept only a few invitations each year. Travel is particularly stressful, and I tend not to do this unless there's an especially
nice event, or location, or honorarium.
How can I stay in touch?
My news page has an RSS feed.
Just lately I've been hanging out on Facebook.
There are more designs on Shapeways.
Do you take commissions?
Sometimes, if they are fun or righteous or lucrative. Feel free to ask.
You used to have X for sale, when will it be back?
I don't know. When I take a design off the site it's because I've had problems making it with good
quality for a reasonable price. I'll bring it back when evolving technology, or other changes in the
resources available to me, make it possible. At that time I'll announce it on the News page, but
before then I don't know.
Can you make bigger laser-glass pieces?
No, for two reasons. First, no etching laser
that I have access to can fire more than 3½" into glass, so that's the maximum
depth I can etch. Second, large glass blanks are
expensive. The largest piece I've worked on is a 26" square by
4" deep galaxy design, and the blank for that cost over $10,000.
Generally it's a lot of work to generate quotes for projects of this
type, and once quoted they are usually declined because of cost.
How do I clean your sculptures?
Metal
These are shipped oiled to protect the surface from chemical attack,
and I recommend keeping a little light oil on them, as you would any
metal tool. 3-in-1 or Tri-Flow or any light oil is fine. If one gets
dirty, wash and re-oil. If one rusts – this is rare, but it can
happen in a wet or corrosive environment – use rust stripper then
re-oil. I like Jasco Metal Etch, but anything with phosphoric
acid should work. I've used Diet Coke in a pinch.
Alternatively, consider
that you own an iron-rich artifact and you live on an
oxygen-water planet. Letting physics take its
course and enjoying the newly enriched patina is a valid option. In the vast majority of the universe, nothing like itd could ever happen.
Glass
Any glass cleaner such as Windex will work to remove crud. To avoid
scratches on the bottom I recommend using the rubber feet that come
with these, as they prevent grit under the piece from scratching
it. If a piece does get scratched, it's possible to buff out
small scratches with Brasso or any mild abrasive (Google has lots of
advice on this) and elbow grease. If that's too much work, a
little Pledge or other furniture polish does wonders to hide
scratches.
Will you help me make something?
If it's a laser-etched molecule or another scientific subject, please visit
CrystalProtein.com, and my assistant Ray can help.
If it's something else laser-etched in glass, please bear in mind that I work
only on scientific imaging projects. If your design is a car, building, kitten, portrait, or photo, Laser Crystal Awards may be able to help.
Generally I'll work on an outside idea if I love it and it fits
with what I do. it's fine to ask, but please don't take it personally if I decline...there wouldn't be enough time in one life to work on all the projects that come to my inbox, even if I had none of my own.
How can I start making things like yours?
Think of something to begin with – the first one can be simple – and
get busy! You'll need to draw, compute, scan, or otherwise
acquire some 3D data that describes your subject. Then you'll need a fabricator, or a
3D printing service bureau, or a laser etching facility, to make the
object, or maybe you can make it yourself. If you want to try 3D printing, your first
decision will be which machine to use, as they all do different
things. A great service bureau with a lot of useful information is here.
I used to maintain a list of resources here,
but I no longer feel that I can survey the field meaningfully. It's too big – ask Google for what you want.
I wish you good luck, and if you make something nifty I'd love to hear about it.
Can you recommend a course of study to get into your
field?
Not specifically. I recommend doing what you like, learning
about what interests you, and going where it takes you. My path
led through a math degree, an art degree, and many years working as a
programmer. Maybe that was overkill, but then I didn't really have a specific goal of becoming a
CAD/CAM sculptor.
Most of the technology that I use now didn't exist yet, so I was flying blind.
The future's probably going to be even more unpredictable, and I can't think of any
advice but to follow your nose: do what you like and
stay loose. Take things seriously. Learn some manual skills, maybe join a hackspace if there's one near you.
Make sure to have a day job lined up: one where you can always get work, it doesn't eat your life, and it
makes a dollar or two. It's difficult to make nice things on
waitron money, and I've never noticed that being stressed about cashflow did my work any good.
Regarding CAD modeling and 3D manufacturing I'm self-taught, so there
I can't recommend any educational method other than to download some
tools and get started. I used to maintain a list of resources here,
but again I no longer feel that it's a meaningful list. Ask Google – it knows.
I'm writing a report, tell me something about what you do.
Much of what I have to say about it is on this
site already. If you have a specific question that doesn't seem to be answered, go ahead and ask. I can't answer general questions such as "What inspires you,"
and "How do you make your art". "Was piece X inspired by katydid wings or artichoke leaves?" is more likely to get a useful response.
Question not answered here?
Write, I'll answer if I can.
