Investment casting

There are good reasons why customers from demanding industries, such as aerospace, automotive, pump industry and artists, started early to prefer PMMA-printed investment casting patterns. Highest detail accuracy even in filigree details, no limits in geometric complexity and a resolution that is not economically feasible with conventional methods of tool production.

And this without annoying support structures and time-consuming post-processing of the models. At the same time, prototypes, small and medium series can be realized in the shortest possible time and at a significantly lower cost using additive processes. The use of large-format 3D printing systems is also opening up completely new areas of application in many industries. For example, the layer construction process has already become firmly established in all areas of automobile production due to its production speed and design advantages. The particulate material used is polymethyl methacrylate (PMMA), an acrylic plastic with excellent burnout properties.

3D printed PMMA models open up new scope for investment casting - qualitatively, technically and economically.

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, additive production processes offer essential economic advantages. Complementary to existing production lines. Or as the backbone of a new agile production that can react ad hoc and without additional costs to rapidly changing component requirements. Produced completely digitally and without tools, complex geometries, undercuts or draft angles lose their importance in the calculation and can be produced almost cost-neutrally.

 

Advantage of geometric and design freedom

Make the impossible possible

voxeljet has highly specialized 3D-PMMA printing systems for binder jetting or processes. Highest detail resolution and speed combined with new scope for design freedom are the focus of our technologies. This means that even very thin-walled components without the risk of shell breakage and complex, CAD-optimized sprue systems can be pressed in a single work step. The enormous time and cost expenditure of conventional, tool-dependent pattern making for complex geometries is completely eliminated here and opens up market segments for investment casting such as spare parts and prototype construction, which today are often economical or bionic lightweight components that cannot be produced conventionally.

Advantage of time saving

Accelerate Time to Market

By eliminating the need for tool and mould making, additive production processes shorten the manufacturing times of components by up to 75%. In product development in model and prototype construction. In the production of small and medium-sized series or in the manufacture of components with many variants. In addition, time-consuming assembly steps for complex geometries in components can be eliminated. The 3D printing process enables these to be manufactured in a single, compact production step. The production of investment casting models is possible in just a few days. Compared to conventional manufacturing processes, this means a time saving of several weeks.

Today, 3D printing offers art an entirely new way to shape the world. One that clearly pushes the boundaries of what is possible and imposes almost no limits on ideas.

Complex geometries and very thin-walled structures can be produced in 3D printing without tools in a single step. Without support structures and including gating systems optimized for the casting process. This not only makes it possible to manufacture the components more flexibly and cost-effectively using additive production processes, but also reduces the proportion of missing parts in the long term.
