We regularly report on the additive manufacturing of houses and other structures with concrete 3D printers. There are now a number of companies working in the field. The founder and CTO of Apis Cor, Nikita Cheniuntai, has published instructions for building your own concrete 3D printer.
As you can see from his instructions, the 3D printer is a converted CNC router. Basically, the router is replaced with a mortar pump and hose. In his post, he explains where to buy the parts for the concrete 3D printer and how to assemble the CNC system and then make the modifications for the printer.
According to his shopping list, he comes up with a price of $7,128.02. That’s the equivalent of 6,336.56 euros. However, prices can vary depending on the dealer. Likewise, the working time is not included.
One thing to consider with this 3D printer for concrete is that there is actually no Z-axis at all, or rather it is very limited. This means that the design is intended for flatter concrete structures. Theoretically, you can adjust the height of the entire machine to create taller structures.
Nikita Cheniuntai has also uploaded a video showing the printer in action.
Apis Cor, the company founded by Nikita Cheniuntai, builds concrete 3D printers itself. However, these are larger and offer more possibilities. This means that houses can actually be printed.
