XXL 3D Printed LEGO Go-Kart

This week’s choice is the huge XXL 3D printed LEGO kart made by Matt Denton.

Denton is a British animation expert who works in the film industry. These are the skills needed to make this item. He recently released a video detailing the project.

Denton has been making Lego karts for his nephew and decided to make them bigger. One is 5 times the normal size, but still too small to allow his nephew to sit down. Therefore, Denton decided to make it bigger, not only for his nephew, but also for him to sit down and ride the bike. Yes, he intends to power the vehicle electrically. He said he hopes it will develop “fast”.

Denton uses Alibre Design Expert as his CAD software, which can guide us through his design decisions. It is not as simple as simply expanding the model. Some areas must be strengthened.

Denton uses a pair of TAZ 6 3D printers equipped with a large-capacity extruder and LulzBot Mini 2, which can 3D print the “large amounts of parts” needed to manufacture Lego karts.

Denton used Polymaker’s PolyMax material, which is an enhanced version of PLA. It is easy to 3D print and is very suitable for projects such as this, because the material’s low warpage coefficient and the required larger parts work well.

The size of the parts is very obvious. At a certain point in the video, Denton collected all the parts in a scene to show the size of the pile:

Although Denton did use glue in some places, many parts were bolted together. Some parts need to be beaten in place with a mallet.

Denton showed the entire assembly process in the video, which is very interesting because he must regularly test the mechanical movements of the substructures before they can be embedded in the vehicle as a whole.

After assembly, the heavy kart really supports the weight of Denton, and the steering function is very powerful.

In Denton’s next video, he intends to complete the project by adding a seat and combining electric motors and batteries. I really want to know how fast this super large LEGO car can travel.

This project is a great example of how to use a small desktop 3D printer to create huge, life-sized objects. What will you build with a 3D printer?
