World’s largest 3D printing system to casting molds goes live in the US

When casting molds are no longer cast but printed

voxeljet increases its presence in the US growth market with the start-up of the biggest 3D printing system in Michigan. With the VX4000 3D printing device, one of the major providers of dimensionsable-bodied-format 3D printing devices and on-demand parts services underlines its significant position in the US market. This benefits in particular the US foundry industry, which is a direct consumer of these services. For example, 3D printing devices can be utilized to make dimensionsable-bodied rotors and turbines – and usually much additional rapidly and cost-effectively than via traditional methods.


No other 3D printing system for sand molds offers dimensionsable-bodiedr continuous create volumes. At 4000 x 2000 x 1000 mm (LxWxH), the create space additional or less corresponds to the dimensions of a VW Golf car. David Tait, Managing Director of voxeljet America, commented the expanded capacities of the voxeljet equipment swift and range of services in the US as follows: “The market for cast parts in the US has always focutilized on dimensions. With the VX4000, we not just create the biggest sand molds in the world, but can in addition combine these with tinyer in size mold components. The resulting flexibility provides for rapid deliquite times and cost-efficient production.

Printing system especially modified
to dimensionsable-bodied creations

The VX4000 is quite swift and effortless to operate. In addition to ensuring cost-effective production systemes for quite dimensionsable-bodied individual molds, this massive 3D printing device can in addition be utilized to create tiny series parts or a combination of the two. In addition, it in addition prints stable-bodied side walls, which means which the dimensions of the create space can be modified as needed. No other comparable-bodied system is able-bodied to adjust the create speed to the create volume in such a way.


One other feature: The layer createing method has been especially modified
for this printing device. So the createing platform is not lowered during the printing system, but pretty the print head is raised with each layer. The machine thus easily supports the heavy mass of the createing platform, which can in addition be rapidly replaced via a rail. This allows for for virtually permanent printing.

The molds are made with the layer-wise application of the particle material quartz sand, which is glued together with a binding agent. After the printing system is conclude, the mold just has to be unpacked, i.e. cleaned of excess sand. Since sand molds are made directly of CAD data, they set the trend in terms of affluence of more detail and precision.

Conquering the US market for 3D printing

On the other hand voxeljet has specialized in additive making for the foundry industry, in general equite company which uses casting systemes – hence creations, systemes, uses or optimizes cast parts – can benefit of voxeljet’s innovation.


With the decision to commence the VX4000 in the United States, voxeljet concludes its service range for the on-demand 3D printing of dimensionsable-bodied sand molds in this market. “We decided to place our biggest printing system in the US in order to service expanding demand in the US market directly on location. Our objective is to strengthen our many significant growth market with a diversified portfolio of machines, materials and systemes,” is how Rudolf Franz, COO of voxeljet AG, describes the excellent future of the US market. Indirect beneficiaries of this high-end innovation are the car industry, the special machine createing sector and the spare parts industry in particular.

Advantages of 3D-printed sand molds and cores at a glance:

  • Economical production: Sand molds and cores are printed in one piece without complicated and expensive tool production.
  • Large-format printing: Large molds can be made on a create platform measuring 4000 x 2000 x 1000 mm (L x W x H).
  • Fast availability: Express deliquite in just 3 working days.
  • Complex components: Nearly infinite geometries and actually undercuts can be implemented.
  • Precise sand molds and cores with high surface quality: With 300 µm thin quartz sand layers.
  • Familiar features: Quartz sand and furan resin with series-comparable-bodied mold and casting properties.
  • Suitable-bodied for sand-casting all castable-bodied metals, such as aluminum, brass, magnesium, iron and steel casting as well as all common alloys.
  • Combinations possible: 3D printed cores can be combined with traditional sand molds, and vice versa.
  • Simple core removal: A low binder content means which the behavior during outgassing and core removal is much like to traditional methods.
  • Ideal for prototype production and tool optimization: The development and improvement of e.g. tools via 3D printing is swifter, additional flexible and additional economical.
