OPEN VS. CLOSED SYSTEMS

Anyone who deals with additive manufacturing very quickly encounters two completely different worlds. On the one hand there are closed systems in which machines can only be operated with materials and software from the machine manufacturer. On the other hand, open systems where manufacturers concentrate purely on machine development and leave the rest to their customers.

At EVO-tech, we offer the best of both worlds and want to make the differences and benefits clear to you.

You often have to look at the "closed system" issue from a different perspective to understand the real implications. Imagine you buy a CNC milling machine, which you could only use with tools, clamping devices and raw materials from the manufacturer. Due to the associated dependency, no entrepreneur would want to make a decision like this. On the one hand, this results in significantly higher costs, on the other hand, it enormously limits the number of possible applications!

ADVANTAGES OF OPEN ADDITIVE MANUFACTURING SYSTEMS

No dependencies on just one supplier
Current crises show us how important it is for companies to have flexible supply chains and not just be dependent on one supplier. In the past few years there have been multiple material delivery problems with closed system providers.
Significantly lower material costs
The open system leads to pricing for consumables in the free market economy. This gives you, for example, 1KG ABS filament at EVO-tech about 75% cheaper than with comparable closed systems.With a service life of 8 years, 3000 printing hours per year and approx. 40 kg of ABS material per year, you save approx. €36,000 in material costs over the live time when purchasing an EL-140 from EVO-tech compared to closed machines from
Open to new developments
Closed systems usually only offer a few materials. New releases are only available for high update fees, if at all. With our open systems, you benefit from our regular material innovations, while at the same time you can also use special materials and new developments from third-party suppliers.
More applications feasible
Due to the great freedom in the choice of materials, in programming and the significantly lower material costs, in our experience, twice as many applications can often be implemented profitably in companies

DISADVANTAGES OF OPEN ADDITIVE MANUFACTURING SYSTEMS

Slightly more training effort and expert knowledge required when selecting materials and parameters
Similar to CNC milling, there are many possible ways and parameters to achieve your goal in additive manufacturing. It all starts with understanding the requirements for the component and the associated selection of the right material and parameters. This selection is often decisive for economic efficiency and technical feasibility.

Open systems present both us and our customers with greater challenges. However, it offers more possibilities than closed systems. That is why we at EVO-tech have developed a multi-level training program and standard parameters for our 16 materials. For special materials and series applications, we are happy to support our customers as a development partner.

EVO-TECH OFFERS ADVANTAGES OF BOTH WORLDS

Both open and closed systems sometimes appeal to different groups of buyers. Experienced users. who work in additive manufacturing often tend towards open systems. Newcomers, on the other hand, are more inclined towards "plug and play" closed systems.

At EVO-tech we offer you the best of both worlds. To enable you to get started quickly, we have 16 different materials including parameter sets that we have tested in different quality levels. Nevertheless, you get an open machine from us that complies with all industry standards and is therefore open to other material manufacturers.

Your benefits in a nutshell:

Independence from the material manufacturer
Lower material costs
Always at the cutting edge of material development
No unlocking costs for new materials
16 different materials with predefined parameters directly from the manufacturer
Development of internal additive manufacturing know-how
High flexibility in programming
