How to use a 3D-printed asphalt shingles roof

As the global climate warms, the costs of building roofs and building barriers continue to rise.

Asphalt is increasingly used to protect buildings against floods, heat and storm damage, but it also has an impact on air quality, and it has been implicated in premature deaths, asthma attacks and other health problems.

The latest findings show how to design buildings that protect from both, with a 3-D-printable version of a shingle made from the asphalt. 

Asphalt is a porous material that is often used to seal buildings and to hold together the roof.

It has the properties of waterproofing, but also has the potential to expand into the building, spreading the stresses on the building and its occupants. 

For example, if a building were to be built on a beach, it could take on water and damage it, as the sand would be able to hold the building together. 

To find a suitable asphalt shim, researchers at the University of Washington and the University at Albany in New York used a 3d-printing technology to create a material that can stretch and expand to create the perfect shingle for the purpose. 

“This is the first time that we have demonstrated this technology and are able to do it at this scale,” said Jie Chen, a professor in the department of mechanical engineering at the university and the lead author of the study. 

The researchers were able to create this shingle using a technique called “dendritic modification,” or DMR. 

Using a 3×3 grid, the researchers first created a surface on which they could put an adhesive layer. 

They then placed the shingle on a substrate that could hold the cement cement. 

Next, they coated the surface with an adhesive that could stretch and contract the material. 

Finally, they used an electron microscope to visualize the structure. 

It was clear that the adhesive was not elastic, but that it did not deform. 

A 3D printed asphalt shink “The 3D printing of the shingle is a key technology to address the need for resilient buildings,” Chen said. 

While there are numerous uses for a shingled roof, the first is to prevent damage from rainwater.

When a raindrop hits the asphalt, it can break the roof down and cause damage to the roof and its contents. 

When the rainwater collects, it mixes with the cement to form a pool, and this pool can cause damage. 

Building a roof with a shim could reduce this pooling effect, but if the water is high enough, the water will cause the cement, which can be hard, to expand, Chen said, and the building could collapse. 

Another benefit is that the shink can be built quickly. 

Chen and his colleagues used this technique to create an asphalt shimmer with a surface area of 1.6m2 (3.5 acres), and then coated it with a coating that could extend to 1m2. 

Although the material was made of a combination of asphalt, cement and cementitious epoxy, the research team hopes to have the material printed at higher density. 

One thing to keep in mind is that these shingels could also be made with other materials such as polyethylene, which is stronger than the typical asphalt.
