Printing 3-D models in stainless steel
August 4th, 2009 by JD
At one point in my life, I wanted to be an engineer. Well, yes, the kind that drives steam engine locomotives, but that’s not what I’m talking about here. I wanted to be the kind of engineer that used a slide rule when I was young and then moved to computers, later.
I’ve been fascinated with mathematics and doing practical things using math.
It turned out that I just wasn’t suited to be an engineer. But, I still love practical applications involving mathematics.
One such application is CAD/CAM (computer-aided drafting and manufacturing). I taught myself how to use a couple of CAD programs about 20 years ago and enjoyed it, but not much more than drafting using a big table and plastic triangles. It just isn’t for me.
Along the way, I learned a bit about 2.5-D and 3-D CAD.
Just as I’ve always wanted to be a sculptor, but lacked the talent, I’ve always wanted to build 3-D models, but lack the talent for that, too. So, I’ve remained an outside observer, watching the developments and learning a bit, here and there.
I’ve watched as it became possible to print a 3-D model in resin and plastic. In fact, I have a small, plastic sculpture of a human head that was printed using one of these techniques sitting on a bookshelf across the room.
Today, I ran across a company called Shapeways and loved their slogan, “Passionate about creating.”
What intrigued me, initially, about Shapeways is that it is kind of a Zazzle or CafePress for 3-D model designers. You can upload your model and they’ll print it for you. You can then have it shipped to you or even sell it in a Shapeways shop.
As I said, I don’t have the talent to do this, but I enjoyed looking at some of the galleries.
A friend of mine, who is a sculptor, and I spent some time experimenting with creating what are actually 2-D models with depth using a laser engraver many years ago. I could do the drawings for that and we tried printing the products in plastic and wood. We even tested creating wax models from the originals and casting them in silver and pewter.
It was intriguing and had some nice possibilities, but that was about the time Mom became sick and I chose to close my metalsmithing business and become her full-time caretaker. So, we never really did much with it, after that.
Still, every now and then, he sends me a link to a website or an article cut from one of the many magazines he reads that talks about new developments with laser engravers and 3-D model printing.
This time, I get to send him a link to something he may not know about.
One thing that really caught my attention is that Shapeways now offers the ability to print 3-D models in stainless steel.
That’s a huge jump forward, as far as I know.
It’s an interesting process. They print the model using layer after layer of stainless steel powder that is bound with some kind of binding material. When printing the model is completed, it is heated and cured, and then infused with bronze. After that, it is polished and ready for delivery.
One thing I really liked is their section on Expectation Management talking about the limitations of the process and the requirements for successful printing in stainless steel. It shows, to me, that they have caring people there who want you to be happy with the results you’ll obtain.
I know absolutely nothing about Shapeways other than what I read this morning. This is not a personal recommendation. However, if you have the talent to create 3-D CAD designs, Shapeways may be something to look into for fabricating your models.
It’s not something I’ll be doing, but I do find it fascinating.
Act on your dream!
