Sandstone is a kind of sedimentary rock, which is mainly composed of sand grains, and the sand content is more than 50%. Most sandstones are made up of quartz or feldspar, the most common constituent of the crust. The color of the sandstone is related to the composition and can be any color, the most common being yellow, red, brown, grey and white.
Some sandstones are resistant to weathering but are easy to cut, so they are often used for building materials and paving materials. The particles in quartz sandstone are relatively uniform and hard, so sandstone is often used as a grinding tool.
Sandstone can be divided into three major categories: quartz sandstone, feldspar sandstone and lithic sandstone according to its sedimentary environment. Sand and sandstone form the main reservoir of oil, gas and groundwater.
Colored sandstone is a kind of decorative material with warm colors. It is elegant and warm, harmonious and luxurious, and is unique among many stone materials. It is called "Lishi". It is a kind of high-quality natural stone without light pollution and radiation. It has no radiation damage to the human body. It has the characteristics of sound insulation, moisture absorption, damage resistance, outdoor weathering, no long moss, easy to clean and so on. These advantages make sandstone a widely used building stone. Buildings made of sandstone hundreds of years ago still have a charm, such as Notre Dame, Louvre, the Royal Palace, the US Congress, and Harvard University.
In recent years, sandstone, a natural building material, has been promoted by fashion and natural architects and is widely used in commercial and home decoration.
When colored sandstone is used in building materials, traditional processes produce a lot of waste due to cutting, such as fine sandstone powder with very fine particles. If you use colored sandstone powder in 3D printing technology , it will be a resource-saving and environmentally friendly choice.
The 3D printed color sandstone material introduced by i.materialise adds a layer of UV resin coating to the surface, making the printed objects brighter and have a marble texture. This extremely lustrous surface enhances the expressiveness of the color, especially for dark tones. 3D printed colored sandstone is often used to display portraits, cartoon character dolls, architectural models and other indoor displays. The technology is mostly 3DP (binder jet) technology, which mixes and injects adhesive into the printing material powder for solidification molding.
However, although the color sandstone is a 3D printing material, although the color is strong, the material is brittle, which is not conducive to long-term preservation.

Architectural programmer Michael Hansmail has been exploring algorithms for building complex structures for the past five years. In 2013, they created a digital Grotesque I project using sandstone 3D printers , and in May 2017 announced a large-scale construction project called DigitalGrotesque II, which has 1.3 billion independent surfaces, also manufactured using sandstone 3D printers. to make. The work weighs 7 metric tons and looks like a man-made cave, so complex that it can't be simulated visually in the design process.

Football artificial grass turf is a surface of synthetic fibers made to look like natural grass. It is most often used in arenas for sports that were originally or are normally played on grass. The main reason is maintenance – artificial turf stands up to heavy use, such as in sports, and requires no irrigation or trimming. An artificial turf football field offers numerous advantages to cities, schools and clubs. First and foremost is the high level of playability. This is because, unlike natural grass, synthetic football fields do not require regeneration phases.
