It's cool how much they accomplished though, with the testing and methods.

That is a really cool 3D printer/ method of making the chassis. What kind of materials can they do? How long did it take to print the robot?

The printer runs at between 10 and 40 lbs per hour. The majority of the robot is printed. It has about 25 lbs worth of printed parts (chassis, forklift, truss...) so under 2 hrs. The material we used is glass and carbon fiber filler ABS. BAAM uses pellets as the feedstock so it's cheap ($2 to $5 per pound). So the total cost for their printed parts on the robot was. $100. We are putting together a much larger printer, 8'x20x6' with a new extruder that runs at 100 lbs/hr. We are going to try to print HVA a new pit for Championship
