The Stratasys H350 3D printer represents a transformative leap in 3D printing for manufacturing, offering outstanding consistency and control for production-scale applications.

An overview of the H350 and how it works

At the heart of the H350 is the advanced Selective Absorption Fusion (SAF) technology, an innovative print process that leverages precise timing and thermal management in order to deliver highly accurate results. This technology ensures extraordinary part quality with fine details and robust mechanical properties. SAF’s industrial-grade repeatability and efficiency enables manufacturers to reliably produce high volumes of parts with intricate geometries, setting a new benchmark for what’s possible in 3D printing.

The H350’s sophisticated approach to additive manufacturing empowers businesses to transcend traditional boundaries, optimizing their production capabilities for the demands of modern industry.

Various case studies presented by Stratasys for the H350 3D printer highlight a range of features that demonstrate the machine’s capabilities in professional settings that enable its future in 3D printing for manufacturing. The H350 is recognized for its ability to produce high volumes of parts efficiently, which is essential for companies looking to scale up their production without sacrificing quality. The cost per part is a significant highlight, while the case studies note the H350’s competitive edge in producing parts more efficiently in cost than traditional manufacturing methods like injection molding, especially when factoring in the costs of creating molds.

The H350 3D printer utilizes a range of materials designed for production-grade applications. The case studies often point to the durability and repeatability of the parts created, which are suitable for end-use and not just for prototyping. Users leverage the H350’s capabilities in powder bed fusion to produce complex geometries that would be difficult or impossible to fabricate with traditional methods. The design freedom afforded by the H350 3D printer allows for innovation in product design.

The printer’s speed is often mentioned, with an emphasis on its ability to significantly reduce lead times, enabling faster turnaround for production and prototyping. These features, as revealed through the lens of real-world applications in the case studies, paint a picture of the H350 as a versatile, efficient, and reliable machine capable of meeting the demands of modern manufacturing environments.

How Goetz Maschinenbau used the H350 for Production Parts

A German mechanical engineering company, Goetz Maschinenbau, turned to 3D printing for manufacturing with the H350 for volume production of small parts. They highlighted the printer’s ability to produce thousands of parts with consistent quality in a short time, which was not feasible with traditional manufacturing methods like injection molding due to high costs and long lead times.

The H350’s Selective Absorption Fusion (SAF) technology provided the accuracy and repeatability needed for their complex part geometries. A quote form Goetz Owner, Philipp Goetz reads;

When it comes to the manufacture of molds, the process can easily cost between 5,000-10,000 euros for each one, with lengthy lead times of 4-12 weeks. To make the investment financially viable, we need to produce a large batch of at least 50,000 parts.”

The H350 3D printer made it possible for Goetz to do profitable part runs of less than 50,000 parts at an efficient and timely rate. Therefore, adding 3D printing for manufacturing is allowing them to increase their service value and competitiveness in the industry.

How Onulis Leveraged the H350 3D Printer to Get to Market Quickly

The Onulis case study is a fan favorite, using 3D printing for manufacturing but incorporating the first step, prototyping as well. Onulis makes a curing apparatus called “The Onulis Wrap” that allows for the post curing of DLP parts as well curing waste PolyJet resin for efficient disposal.

In the WRAP model specifically, there were 46 components printed on the H350 (Nylon PA11). Onulis was under tight timeline and needed to prototype and go into production quickly and efficiently. On this specific unit, not only were they able to prototype their designs and prevent making 46 different molds by printing their production parts on the H350 but they were also able to produce a part with at geometry that was not possible to injection mold at a cost of under $20 per part.

In another example by Onulis, they had a complex geometry that was costing $9.78 to injection mold, however the H350 3D printer was able to prototype print the same part for $6.28 per part with an overall reduction of 36%. This specific part was able to print 100 per build which is 13 hours of print time and 26 hours of cool time. Therefore, without adding any other parts into the build, over the course of 39 hours, they produced 100 parts with a 36% cost reduction, compared to the original process of injection molding.

To injection mold 100 parts, Onulis had a 12-week lead time in order to not only create the mold but also shoot it 100 times and process the parts. This is a great example showcasing the overall reductions behind cost and time. Onulis is now able to produce their production parts in PA11 on the H350, but they are also able to do their prototyping on the machine as well, saving them both time and money.

Rivelin Improved Iteration Time Before Moving to Injection Molding

Specializing in metal additive manufacturing support removal and finishing, Rivelin Robotics faced challenges with post-processing electrical connectors with complex geometries. The H350 3D printer helped them print and produce their own solution in a timely manner, leading to greater efficiency in their operations.

Their success story highlights the printer’s ability to iterate designs quickly and produce precise and stiff parts essential for their robotic systems from a prototyping and production perspective. A quote from David Mason, the Chief Product Officer at Rivelin states;

The ability to rapidly iterate a second version with a slightly deeper groove is what makes additive manufacturing hugely valuable over injection molded or machined parts.”

Conclusion

In conclusion, the Stratasys H350 3D printer, with its innovative Selective Absorption Fusion (SAF) technology, stands as a groundbreaking advancement in the realm of additive manufacturing. This printer has not only set a new standard in the industry for its precision, efficiency, and ability to produce high-quality, durable parts, but it has also revolutionized the way companies approach production.

Through various case studies, the H350 has demonstrated its unparalleled capability in producing complex geometries, maintaining consistent quality, and significantly reducing both production costs and lead times compared to traditional manufacturing methods.

Companies like Goetz Maschinenbau and Onulis have harnessed the H350’s potential to realize production goals that were once deemed unfeasible, underscoring the printer’s role in making smaller production runs financially viable. Similarly, Rivelin Robotics’ experience with the H350 3D printer exemplifies its contribution to rapid prototyping and efficient production in specialized applications. These real-world applications underscore not just the technological superiority of the H350, but also its practical impact in enhancing operational efficiency, fostering innovation, and empowering businesses to meet the dynamic demands of modern industry.

The Stratasys H350, therefore, is more than just a 3D printer; it is a catalyst for transformation in manufacturing, pushing the boundaries of what’s possible and opening new avenues for design and production.
