Re: Polycarbonate/Plexiglass Ruling
Waterjets cut all of these materials pretty well with no fumes.

It was really nice to work for a waterjet maker back when I was on 1318. our 2009 robot was made all of waterjet polycarbonate sheet (which was recylced from a building demolition!) Our 2008 robot had a waterjet 1/4" titanium sheet as the only frame element. everything just bolted right to it. it also has infinite rotation swerve drives using waterjet copper sheet for custom slop rings. |

Re: Polycarbonate/Plexiglass Ruling
As exciting as waterjets are, my team has found huge success with desktop CNC routers. They are relatively cheap, relatively intuitive to use, and cut softer materials like wood and polycarb very easily, and are advertised to cut aluminum if you know what your doing.
We use a Shapeoko 3 XL with DeWalt Router and it's become our new favorite tool. It has a build volume of 33" by 17", and comes with very easy to use software. Our XL version is about $1,600, abut you can scale up(XXL 33" by 33") or down(Standard 16" by 16"). Feel free to pm me if your skeptical, on the fence about buying one, or just want to know more! :D |

I have also done an experiment for a non-FRC related group of kids. I took two identically sized pieces of polycarbonate and acrylic plastic (about 2" by 12"). (Fun note: polycarbonate is easy to cut with woodworking power tools like miter saws. Acrylic, I scored with a knife and snapped.) To the eye, other than the cross section, both pieces look very similar. Then I folded the polycarbonate in half like a sheet of paper. You end up with a nice 90-degree bend. Then I tried the same with the acrylic, and it shatters into pieces (wear gloves). Insert your favourite object lesson here about things looking the same but being very different inside, don't judge inward strength by outward appearances, looking OK on the outside but handling stress and pressure very differently on the inside, etc. |
