Scientists have developed a faster and cheaper
An effective 3D printing method that can be used to print objects of all colors.
People are exploring the wide application of 3D printing
According to research published in the journal Nano Letters, it is widely used, including manufacturing, medical devices, fashion and even food.
However, one of the most effective forms of 3D printing has a major drawback: it can only print objects in gray or black.

According to research published in the journal Nano Letters, it is widely used, including manufacturing, medical devices, fashion and even food.
However, one of the most effective forms of 3D printing has a major drawback: it can only print objects in gray or black.
Now researchers at the Spanish Institute of photon science (IFCO) have adjusted this method so that it can print all the colors of the rainbow.
The selective laser sintering (SLS) printer uses a laser to heat a specific area of the powder material (usually nylon or nylon) for the purpose of melting or sintering the powder to form a solid mass.
The printer then selectively sintering new powder materials layer by layer until the required 3D structure is obtained.
In order to reduce the energy demand for this process, the researchers added compounds called light sensitizers to the polymer powder.
These materials, such as carbon nanotubes, carbon black and graphene, have a much stronger ability to absorb light than polymers and pass heat on to them, thus enabling the use of cheaper, lower materialspower lasers.
However, carbon
Only gray or black prints can be produced based on photosensitive materials.
Gerasimos Konstantatos, Romain Quidant and colleagues at IFCO would like to find a photosensitive material for color printing through the SLS method.
The researchers designed the gold nano stick to strongly absorb the near
The infrared region of the spectrum is almost transparent to visible light at the same time.
They are applied to it with silicone and then mixed together with polyamide powder to print 3D objects.
They found that gold nanobars are much better than industry-standard carbon black in converting light from laser to heat.
The new photosensitive agent can also produce more white and-
