3D function made from flat parts

I've been looking for a good example of this kind of construction for a while now. The idea behind this is that you can assemble a series of thin pieces together to make a continuous, arbitrarily complex curvy surface. Of course, your accuracy will be limited by the thickness of the pieces.

This is a 3D surface function made from a series of thin pieces. It looks like cardboard. The pieces were laser cut.

I've also read about prototype rocket bells being created using a similar technique.

Why waterjet?

Big Blue Saw has focused on bringing our customers the best online waterjet service available. I'm often asked by friends and potential customers why we use waterjet cutting to make our parts. The waterjet cutting process offers several advantages:
  • Waterjet cutting works with a wide variety of materials, including nearly all plastics and metals.
  • The stock material is mostly unaffected by the cutting process. Little heat, for example, is generated by a waterjet cutter.
  • Nearly any two dimensional shape can be cut from stock material.
  • The accuracy is high enough for most ordinary purposes.
  • You can design parts using common 2D CAD or drawing programs, making it more accessible to non-specialists.
  • Its easy operation and simple design lower costs.
Our long-term goals do include offering other types of machining and manufacturing. Waterjet cutting does have its limitations, but I figured that it was the best technology to start Big Blue Saw with.

New DemoSat rover in progress

The University of Northern Colorado Space Grant Team is working on a new rover for this year's DemoSet contest. You may recall seeing an article about their first rover on our website. This new rover features an aluminum frame with parts cut by Big Blue Saw. Casey Kuhns posted some photos of the work in progress over on flickr.
