The casting industry is in a state of upheaval. The ability to produce ever more complex shapes and volatile quantities while shortening delivery times are becoming increasingly important factors to gain competitive advantages. Even in the age of digitalization, the world is not binary. Therefore, voxeljet is focusing on the intelligent fusion of classic foundry technologies with flexible 3d sand printing. For sustained optimization and increased efficiency across the entire value-added chain in production.

Whether it’s prototyping, spare parts production or agile industrial series production. With Binder Jetting sand 3d printing technology, and the tool-less production of sand molds and cores for classic metal casting processes, we are opening up new horizons for the foundry industry. Without restrictions in individualization, lightweight construction and demanding or complex geometries. And not to forget, with a great potential for cost optimization in the manufacturing process.

3d sand printing ensures competitive advantages

Advantage of cost efficient

Optimize costs

Complex geometries and increasingly varied and smaller batch sizes. Wherever conventional processes reach their economic limits due to cost-intensive mold construction or changeover times, 3d sand printing offer essential economic advantages. Produced completely digitally and without tools, undercuts or draft angles lose their importance in the calculation and can be produced at optimized costs on demand and right on time.

Advantage of flexibility

Produce on any scale

voxeljet has the world's largest and most powerful sand 3d printer for large components or large batches of small components. We overcome the limitations of traditional 3d printing systems and processes. The use of common foundry materials such as sand and complementary binders ensures optimal casting results through seamless integration into traditional production processes.

Advantage of time saving

Accelerate Time to Market

By eliminating the need for tool and mold making, additive production processes shorten the manufacturing times of components by up to 75%. The 3D printing process allows them to be manufactured in a single, compact production step. Sand molds and cores can be produced in just a few hours. That means a time saving of several weeks.

By using voxeljet's binder jetting technology, we can significantly reduce the delivery time of moulds and cores for our customers. In addition, we achieve new records in terms of the size and weight of the parts we cast.

How does sand 3d printing work?

The coater applies thin hair layers of sand on the building platform that will be selectively bonded by the print head. These processes are repeated until the mold or core is built up and ready. In practice, several products are usually produced in a single job box to make the best possible use of the build space.

voxeljet‘s sand 3D printer lineup: For sand casting molds & cores

voxeljet supports you in this process from rapid prototyping, efficient machines for the production of medium-sized series orders to the world’s largest and most powerful sand casting printer for additive mass production of large components or large runs of small components. With a wide range of possible sand/binder combinations and the ability to choose freely between manufacturing based on furan, phenolic resins or inorganic binders. You can also obtain molds and cores through one of our worldwide sand 3d printing service centers to thoroughly test sand casting processes without your own investment in hardware, as well as to optimize products or accelerate their development.

3d printing sand casting cores & molds from your CAD files

voxeljet 3d printed sand casting technology change the framework parameters in mold making for foundries sustainably, technically and economically. Molds and parts can be design with CAD software and transferred to the 3D printer by the click of a mouse. Thus, a first Mock-Up or Prototype is available in the shortest possible time to test designs or a large number of variations.

Adjustments can also be made digitally to make the production of the final component more flexible and streamlined. By eliminating expensive tool making, 3d printing casting molds supports the realization of undercuts, complex geometries or thin-walled structures. With degrees of freedom that go far beyond the possibilities of conventional mold making, 3d printing molds for metal casting can be easily integrated into existing production landscapes.

3d printed casting cores

3d printed sand casting cores can easily be integrated and combined with conventional sand molds. This hybrid approach ensures a high degree of cost efficiency and production streamlining. Only the most complex structures, the sand core, is 3d printed. To withstand the high temperature or pressure stresses during casting, 3d printed casting cores can be manufactured from various special sands.

3d printing molds for casting metal

3d printing casting molds ensure cost-effectiveness for prototypes, small series and serial production. Moreover, the geometric freedom, tool-less production and high printing speed of binder jetting 3d printers, reduces delivery times from prototype to final part significantly, making it even possible to produce lightweight designs in no time. 3d printing molds for metal casting therefore heralds a new era for foundry men.
