Do you like Legos? Karts? What about Lego go-karts? Otherwise, we have a video that should convince you that this is the perfect combination. He comes from Matt Denton on YouTube, where he chronicles the progress of his efforts to build a life-size Lego kart printed in 3D. His latest download shows him in detail the design and engineering process, although the highlight of the video is that he takes the kart during his first test drive in a large warehouse.
Denton 3D prints the oversized blocks using a variety of different PLA plastics for various parts, such as the use of PolyLite PLA for non-mechanical parts and PolyMax PLA for more integral ones such as the chassis. Denton also details the electric motor, axles and brake system, showing where the batteries are located with the control unit. He plans to add an LCD screen later that will display battery levels.
All of this is just over half of the video. The rest are Denton and his friend who are taking out the Lego go-kart for their first test drive. It was a great success with only a few minor technical difficulties, like the steering wheel that came off at one point. They were able to increase the horsepower, putting the top speed of the race out of reach inside the warehouse.
Parts of the version require improvement. One problem the kart faced was the wheels, which turned on the rims and made braking less effective. Earlier in the video, Denton mentioned the possibility of adding a differential to improve energy distribution and management.
Here, for now, is his go-kart Mk 1 Lego as there will be later models with different adjustments, upgrades and improvements until it reaches its final form. It sounds like a driving explosion, and we bet there are more than a few willing to pay for such a deception. This writer would.
