The construction site for the new Arts and Humanities building at Durham College is one of the busiest places in the city right now. Four tradespeople are working hard to get this building ready for students over the next two years. They use a new type of printer that sprays mortar onto walls rather than pouring concrete on a flat surface. The printer may seem like just another piece of equipment that can be used during COVID-19 but it actually does something quite different from other machines we’ve seen so far!

The machine is being used to apply a “scratch coat” to the exterior walls of the new Arts and Humanities building at Durham College.

The machine is being used to apply a “scratch coat” to the exterior walls of the new Arts and Humanities building at Durham College. The scratch coat is a special mix of sand, cement and water that’s sprayed on in layers. The initial layer provides some structure for subsequent layers, but it doesn’t have enough strength to support itself yet.

The machine sprays mortar, which is a mix of sand, cement and water, onto the wall. The spray gun has a nozzle that squeezes out the mortar in a thin layer that hardens into a solid surface once it dries. This surface is then used to apply stucco.

The mortar hardens into a solid layer of concrete and then forms the surface for applying stucco.

You probably know that the mortar hardens into a solid layer of concrete and then forms the surface for applying stucco. But did you know that stucco is made from cement, sand and water? That’s right—you can use your mortar as a starting point for making stucco! All you have to do is add some water to it, along with a little bit of sand or aggregate (small rocks) if you want.

Stucco is used on both interior and exterior surfaces because it’s so versatile. It can be applied directly onto brick walls or wood frames without any other type of reinforcement needed—and because it’s such an affordable material, many homeowners opt for this option when they’re looking to save money on repairs after storm damage has occurred at their home.”

Concrete can be poured onto a flat surface but not on walls.

Concrete is not suitable for smooth surfaces and can cause a lot of problems when it is applied to walls. Concrete has a grainy texture and needs to be poured on a flat surface. Wall printing machines allow concrete to be sprayed onto walls where it dries in the shape of whatever you want.

That’s where this new printer comes in.

In recent years, there’s been a lot of interest in a new way of building.

It’s called wall printing, and it’s changing the way we think about construction.

The wall printing machine works like traditional 3D printing (also known as additive manufacturing). It uses computer software to design buildings using CAD models and then prints them using specialized materials that harden into solid structures. This can be done on site or in the factory before installation. Wall printers work with concrete—which makes up most of our roads and houses everywhere on earth—but also plastic materials called reinforced concrete composite (RCC), which are made from recycled plastic mixed with cement paste inside PVC pipes at high temperatures for about 24 hours until they harden into durable blocks that can withstand earthquakes or even bullets!

Conclusion

So, it’s time to get your walls ready! Concrete printing is a great way to create custom designs on your exterior walls. If you’re looking for something that will make your home stand out from the crowd then this machine is definitely worth checking out.
