The cost effectiveness of 2K (two-component) 3D concrete printing – 3DCP – can be significant when compared to finished materials. Here are some reasons why:
The ability to use a local source of the material, develop and create recipes from it.
Additives are liquid by nature, for a one-component material it is necessary to dry it. This takes a lot of energy, which is why they are more expensive.
What is the shelf life of sand and gravel? Yes, you are right, is unlimited unless it is mixed with cement and admixtures. With two-component concrete 3D printing, you can produce exactly the material you need at the time. There is no need to stock tonnes of expensive 3DCP materials that age slowly.
Need more reasons to use 2K 3DCP technology?
- Possibility to change the mix according to the project and the weather
- Fine tuning of parameters during the 3D printing process itself.
- Freedom and independence
- Price: if you are serious about 3DCP and want to print houses or huge structures, the 2K is the right choice.
