Video demonstrates the functionality and strength of a low cost, light-weight, fully 3d printed part.
Everyone wonders how strong a part printed on the Mark one can be.
We printed a tow hook and successfully towed a 3000 lb car uphill. Check out the video which covers the printing process and part testing:

A few Details:
Materials: Nylon & Kevlar. (Carbon Fiber and fiberglass can also be 3d printed).
All composites shown are made with continuous strands, providing exceptional strength (30 times stronger and stiffer than ABS).
Resolution: 0.1 mm
Print Time: 7 hrs
Test: 3000lb car (without a driver & Engine not running) is towed uphill.

Wow this is impressive and helps illustrate the strength and capabilities. Thanks for sharing @RajanPB! Is this your print?
Hi Nikki! Always a pleasure to share with the 3d hubs community… Yes, This was done with our LA based printer. .

Thanks for sharing. Very interesting process indeed. However, anyway you can provide actual strength test numbers? In reality, I don’t think it’d take much to do what you guys did in a video. Wouldn’t take much strength on the hook to keep the car moving, either. IMHO, you could probably pull this off w/ a nice piece of ABS or PLA. Maybe you guys can do a launch while using that hook to pull the car…=p
@DaJay23D Here are the Tensile, flexural and compressive strength values for all 4 materials (carbon fiber, fiberglass, nylon and kevlar). It is possible with abs but the part would have to be very thick to the point that it wouldn’t make sense…
whaaaat? This is amazing!
Hello, can you tell me what the size of the chopped Kevlar fiber in your material is?
Thanks!
It’s not chopped, it’s continuous. It’s about 0.3mm
