Product Description
In casting production, sand casting is a common casting process. Casting is one of the ways of metal processing. It is a metal processing method in which the liquid metal is poured into the casting cavity corresponding to the shape of the parts. After the liquid metal is cooled and solidified, the blank of the metal parts with a certain shape, size and performance is obtained. But the more complex the structure of the casting is, the more troublesome the mold modeling is. Rapid prototyping makes the difficulty of the forming process independent of the complexity of the physical shape to be formed. Therefore, many modeling tasks of sand mold today have to be completed by 3D printer. This valuable technical feature enables it to best adapt to the competitive environment of the contemporary manufacturing market and develop rapidly.
Why Is a sand 3D printer the future of Additive Manufacturing?
You might be surprised, but sand 3D printers go back to the late '90s! Generis and MIT are responsible for this huge development. But how exactly does this technology work? At what stage is it after 20 years of research and improvements? Today, we will focus on the innovations of sand 3D printers! Are you ready? the right image is the old traditonal sand casting process. It costs more than 1 month to finish a metal part by sand casting. Nowadays The popular addtive manufacturing technology (often referred as 3D printing technology) is a kind of manufacturing principle of breakthrough, it doesn't require any special tools, and not be restricted by batch size, can directly from the 3D CAD model quickly into a three-dimensional entity model, and the product cost almost nothing to do with the complexity of the parts, especially suitable for complicated, with a fine internal structure parts manufacturing; And manufacturing is so flexible that a single machine can be used to make parts of all shapes and sizes.
Rapid prototyping technology requires only 30% to 50% of the time and 20% to 35% of the cost of traditional processing methods to directly produce product samples or molds. 3D printing prototype has been widely used in the fields of machinery, electronics, automotive, aviation and aerospace. With the improvement of this technology, it has brought a revolution to the manufacturing industry.
How does a sand 3D printer work?
Sand 3D printer, like all other printers, works with layers. It uses sand alike materials such as ceramics, metal particles and also silica sand. The technology used for those machines is called Binder Jetting and is widely used with different materials, for example, Stainless Steel 316.
Binder Jetting printers spread a layer of the material and then bind it with an agent, which solidifies the particles. A layer for sand 3D printer is 140-200 micrometers. When it comes to sand 3D printers, they do not require heat to produce parts. This is very important as it enables high volume 3D models to be manufactured.
The process of 3D printing involves laying a layer of sand, curing it with adhesives, and then laying layers on top of each other. The material of the sand mould is quartz sand, because it uses resin to bond the sand material together, so this kind of sand is also called resin sand. The layers of the resin sand material can be as thin as just 300 microns (the thickness of three piece human hairs).
Why is the development of 3D sand printing important
The main benefits of sand 3D printing are a large volume and small material waste. Leftover material which is not bound can easily be reused. The downside is that the parts are not very strong compared to metal 3D printing for example. However, sand 3D printer doesn't need additional support and those advantages might be crucial for one industry.
The casting processes are an old and commonly used method to produce parts in various industries. From automotive to aerospace, casting has been improving the production process for ages. It is not the easiest manufacturing method though. The master model around which the mold is created has to be absolutely perfect. Also, the material used for the master model is important, wax can be easily pushed out by metal, but wood or clay models have to be removed before casting processes.
Another problem during conventional production is that craftsmen preparing the master model need to consider and predict a lot of conditions that the model will be exposed to, such as shrinkage, solidifying in the model, flow, or reactions with metal.

Sand 3D printers can be just the perfect solution for that. They can revolutionize the casting industry actually. How? Thanks to sand 3D printers we might not need master models anymore! We could 3D print models straight away instead of creating them around master models.
Because a set of mold is often combined by the sand core and the outer mold together, the structure of the sand core is more complex, and the outer mold is relatively simple. Therefore, many manufacturers only use 3D printing to produce sand cores for cost considerations, and the outer mold is still manufactured by traditional processes. Of course, can be directly integrated printing manufacturing. The traditional sand mold manufacturing process is generally: CAD design → process simulation → mold production → fixture manufacturing → sand mold manufacturing → casting. After using 3D printing, the process is CAD design → process simulation →3D printing sand mold → casting. It used to take a month, but now it can be completed in a few days, which greatly shortens the production cycle and saves a lot of manual work.3D-printing sand casting advantages:
1.Save time: short delivery
2.Cost savings: no tools
3.High flexibility for quantity, shape design and variation
4.Almost any complex geometry
5.Complex cores can be integrated and accurately reconstructed
6.Size: from small parts to 2000 x 1000 x 1000 mm
7.Compared with the traditional mold, there is no storage and maintenance cost
8.Any hybrid manufacturing method and the combination of traditional technology
9. Parts/reverse engineering
