The foundry industry is undergoing significant transformation. Increasing component complexity, shorter development cycles, rising cost pressure, and a growing shortage of skilled labor are shaping day-to-day production realities. At the same time, digitalization and additive manufacturing are opening new opportunities—particularly in core production using 3D sand printing.
While the technology itself has been established for years, the real challenge today lies in its industrial-scale implementation. This is precisely where innoMold positions itself as a specialized production partner for foundries.
3D Sand Printing – From Prototype to Series Production
Additive manufacturing has been used in casting applications for more than two decades. The team at innoMold brings over 20 years of hands-on experience with additive technologies for cast components—from early printed models to today’s industrial binder jetting systems.
innoMold has actively supported the development and industrialization of binder jetting technology. Today, this expertise is applied with a clear objective: stable, repeatable, and cost-optimized series production of sand cores.
The company’s technological capabilities are further strengthened through international partnerships, including collaboration with Humtown, one of North America’s leading specialists in industrial sand printing.
Production Focus Instead of Machine Sales
Machine manufacturers also offer printed sand cores as a service. However, their core business remains the sale of equipment.
For innoMold, core production is the core business.
This fundamental difference shapes the entire organization. innoMold is neither a demo center nor a machine showroom. The company operates as a dedicated production partner with clearly defined industrial processes.
Key focus areas include:
- Repeatable quality
- Reliable series production
- Clearly defined production processes
- Continuous cost optimization
By deliberately operating without a machine sales agenda, innoMold acts as a neutral partner without conflicts of interest. The company’s success is directly linked to the success of its customers.
Reducing Technological Risk for Foundries
Operating industrial 3D printing systems requires:
- High capital investment
- Specialized personnel
- Additional production space
- Ongoing maintenance efforts
- Deep process expertise
innoMold assumes this complexity entirely.
Customers benefit from:
- Immediately available production capacity
- Guaranteed quality and delivery reliability
- Reduced technological risk
- No capital investment required
This enables foundries to focus on their core competency: casting.
Measurable Advantages in Production
Compared to conventional coremaking, 3D-printed sand cores offer clear industrial benefits:
- Tool-free production – no core boxes required
- High design freedom – including undercuts and complex internal geometries
- Part consolidation – combining multiple cores into a single core assembly
- Printing of complete, casting-ready molds
- Partial integration of cores into mold halves – eliminating separate cores
- Higher dimensional accuracy
- Reduced assembly effort
- Lower scrap rates
- Reduced grinding and finishing requirements
Application Spectrum
innoMold supports foundries that:
- Do not operate their own 3D printers
- Use innoMold as backup capacity alongside in-house printers
- Require rapid prototyping
- Need to absorb peak production loads
- Produce short- and medium-volume series
- Manufacture complex geometries
- Face bottlenecks in their internal core production
Strategic Location
innoMold is headquartered in Langenfeld, strategically located between Cologne and Düsseldorf—in one of Europe’s most important industrial regions. This location enables short logistics routes, fast response times, and close customer support throughout Central Europe.
Conclusion
3D sand printing is now a production-ready technology. However, the decisive success factor is not the printer—it is the industrial implementation of the process.
innoMold does not sell machines.
