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