How Rapid Prototyping Services Can Work with Concrete Materials



Have you ever wondered if concrete materials can be handled by 3D printing technology? It surely would be a sight to see molded parts created with raw materials using tech that is supposed to be used to cast out prototypes. Thanks to a group of scientist led by M.Papachristoforou, V.Mitsopoulos, and M.Stefanidou you longer have to guess. The team published a paper just this year about this topic, and it’s collected on a book called “Procedia Structural Integrity.” As you can expect, many rapid prototyping services are all over this information waiting to increase their offering on products and services. On the next lines, we’ll have a brief exposure to a few parameters that are required to make this happen.

What is Known So Far About it?

The information available so far is that working concrete with 3D printing technology requires custom-made hardware that can meet specific parameters. The first one is that the raw materials can be shoved down the nozzle of the printer without damaging it, and the piece created needs to hold the shape is being given when it’s deposited. Concrete does have some weight to it so the hardware must be able to hold up the succession of layers that will be put in place by the device. Although the plans are to work with every single raw material under the sun, the technology has proved to be effective so far to handle limestone and river sand as well as a combination of each.

The Ongoing Results of Research

Most rapid prototyping services need to be aware that true concrete is a mixture of a considerable number of aggregates and binders combined with water and plasticizers in some instances. Unlike the regular tooling methods for concrete that are handled by professional almost by eye and memory alone, this method requires a bit more of precision. The tests made by the team of researchers offered positive results when it came to determining the workability factor of the finished product, but it still requires more work, since the results lack the durability of the real deal. The benefits, however, solve quite a few issues that have always plagued the work of contractors over the years.

What has it been Achieved to this Moment?

The first one of the positive outcomes is the fact that the builds made with concrete using 3D printing no dimensional variations. They are, to say the least, a work of precision as rapid prototyping services can only deliver it. The custom-made printer can handle up to five layers of printing material at once. It still needs to be tested with sturdier and more durable materials, but that’s good news when it comes to performance. As for the issues that need fixing, the team handling the research is not ready yet to experiment with hard mixes such as raw cement, but they are willing to work with the next best thing such as fly ash or furnace slang. They are hoping to achieve improved strength and density with alternative options before working with established methods. Will they be successful? Only time can tell!
