Answered: Carbon Fiber 3D Printed Parts

[JustinM]

Hi Karthik,

So in the VEXU Appendix E in the Starstruck Manual it is stated that

Teams are allowed to fabricate their own unique VEX parts from the following additional
items, for each of their robots:
a. Plastic cut from a single 6” x 6” x 1” block
i. Examples of “plastic block” are PVC, Delrin, and ABS
b. Steel OR Aluminum cut from a single sheet no larger than 12” x 12” and no thicker than 0.070”
c. An unlimited number of plastic 3D printed parts, each less than 3” x 6” x 6”

I wanted to see if Carbon Fiber Plastics such as Proto-Pasta CF HTPLA , Markforged Onyx, and Matterhackers NylonX would be legal for VEXU competition use. Of course they would still follow the dimensional rules also.

Here https://vexforum.com/t/answered-clarification-of-vur2-regarding-plastic-alloys/37142/1 you ruled that Nylon alloys were permitted and in the Markforged case, It is a mix of Carbon Fiber and a Nylon alloy.

Thank You

Yes, this is legal.
