Waterjet and 3D objects Part 4

As many of you know, robotics is one of my hobbies. So I was pretty pleased to find out that the Spring Flamingo, one of the first really good dynamically stable walking robots, has body panels made with a waterjet.

Waterjet and 3D objects Part 2

Some students at MIT used MIT's waterjet to create a flexible, interactive surface. The surface can be moved along the same dimension as the cut.

Waterjet and 3D objects

Big Blue Saw currently features waterjet cutting for manufacturing operations. Waterjets are extremely flexible tools, but can't cut slots or pockets like a milling machine. But you can use waterjet cut parts to make real 3D objects. It takes some creative design, but it can be done. The Big Blue Saw RAZR cradle is one example of how this can be done. I also recently found an interesting article which details the "Hole and Tab Method" for making 3D parts with a waterjet. Link.

What does that have to do with the price of aluminum?

Raw material prices have gone up lately, especially for aluminum. Turning aluminum ore (bauxite) into usable metal is very energy intensive. Aluminum manufacturers use electricity to break the elemental aluminum out of the aluminum oxides.

If you've gassed up your car lately, you know that energy prices are up. So aluminum prices are up, too.

Does this affect Big Blue Saw's prices? Only a little bit. Parts made from thicker aluminum stock will cost more in raw materials, but those materials have higher cutting costs anyway. For example: a customer recently placed an order for a part made from 0.75" thick aluminum. His price was about $90. With the new aluminum prices, it would be about $94.

The checkout process has been streamlined. You now don't need to register to be able to check out.

There are a bunch of small changes, too, like improved URLs (good to help us be spotted by search engines) and minor content updates across the site.
