VX4000 - 3D printer for sand molds and cores

The VX4000 uses furan resin optimized for 3D printing and standardized quartz sand/silica. The print head works with a resolution of up to 200 dpi and can therefore reproduce even the most complex component geometries precisely and to an extremely small margin. Ideal for supplementing existing production or for cushioning volatile production peaks.

Understanding 3D Sand Printers and Binder

Typically, the substrate is a silica sand that has been pretreated with an acid catalyst, but it can be a number of other aggregates used in metalcasting, such as zircon and synthetic ceramics. The FA-based binder is similar to the more commonly known furan no-bake binder that is cured using a sulfonic acid, usually toluene sulfonic acid in water. Once the binder contacts the catalyst it cures in much the same

Introduction to binder jetting 3D printing 3D

The cores and molds are generally printed with sand or silica. After printing, the molds are generally immediately ready for casting. The casted metal component is usually removed from them after casting by breaking the mold. Even though these molds are used only once, the time and cost savings compared to traditional manufacturing are substantial.

3D Molds/Cores for the metal casting industry

Molds or cores are made by spreading a blended silica sand and dry acid binder mixture on a flat surface. The bed of blended sand is swiped with a leveling bar as the print head passes and deposits a chemical activator to create the printed shape. Computer software controls the deposition of the activator only where needed to produce the design mold or core component. When completed, the mold or core is
