Sand casting is an age-old method of making designs and shapes of different metals, plastics etc. However, in modern times there is a requirement for very complex shapes and large quantities in a comparatively short time. This is why the research departments of almost every large sand casting company are trying to find new methods to meet this challenge.
This is where a combination of 3D printing and traditional sand casting emerges. This method combines the traditional sand casting method with the modern technology of 3D printing. This new technology, known as 3D printing sand casting, is becoming increasingly popular every day. Most of countries worldwide have either completely adopted this method or are trying to do so.
Benefits of 3D Sand Casting
The ability to 3D print molds for sand casting has revolutionized the sand casting industry. Additive manufacturing has been included as the method of making molds has reinvented the casting process and removed some of its old limitations. There are the twin benefits of more flexibility in design, and this new method is also economically more feasible, as it reduces the cost of the casting process.
This is why many a sand-casting foundry has adopted this simple yet effective method to produce large quantities of molded parts at an affordable cost. B binder jetting is the 3D printing technology used in creating molds and cores from the sand. This method allows for building parts layer by layer using a binder to bond and strengthens each layer. The most common sand materials used in this process are zircon and silica.
Hence if you are looking for a foundry to provide parts of any type, then it is advisable to look for one that uses the 3D sand printing method.
