Insights into 3D printing advancements, material choices, and the machines transforming the industry.
The Open vs. Closed System Debate
The choice between open and closed systems in 3D printing is one of the most hotly debated topics in the industry. Open systems provide unparalleled flexibility, allowing users to experiment with different materials, modify settings, and tailor outputs to their exact needs. In contrast, closed systems prioritize convenience and consistency, often at a higher cost.
While proprietary systems, like those from Formlabs and Markforged, streamline the process with “push-button” solutions, they come with limitations. Material costs are higher, and users are locked into specific ecosystems. However, for businesses prioritizing reliability and efficiency over experimentation, these systems can save significant time and resources.
High-Temp Materials: What You Need to Know
High-temperature materials, such as PEEK and ULTEM, are prized for their exceptional thermal resistance, chemical stability, and mechanical strength. Yet, working with these materials isn’t straightforward. Machines like the 22 IDEX and Stratasys systems offer solutions, but they each come with trade-offs.
- Stratasys Machines: Ideal for businesses needing consistent results with minimal setup. However, they come with a hefty price tag for both hardware and materials.
- 22 IDEX: A cost-effective alternative for smaller high-temp parts. With a bit of expertise in material tuning and orientation, this machine delivers excellent results without breaking the bank.
For larger parts, CNC machining or injection molding may still be the go-to options, though both have their own challenges, such as warping and mold breakage. In many cases, smaller high-temp parts, such as those the size of a softball or smaller, are more feasible and cost-effective for 3D printing.
Why Open Systems Are a Game-Changer
Open systems cater to advanced users who want control over every aspect of the printing process. For companies with experience in material tuning, these systems offer endless possibilities for innovation. For instance, tuning ULTEM 9085 or experimenting with carbon fiber nylon is achievable with open systems like the 22 IDEX.
On the other hand, closed systems simplify processes for industries needing quick, reliable outputs. By embedding years of R&D into their machines, companies like Formlabs ensure their systems work seamlessly without the need for extensive setup.
Key Takeaways for the Industry
The world of 3D printing is more dynamic than ever, with machines and materials designed for both professionals and hobbyists. Whether you lean toward the flexibility of open systems or the reliability of closed systems, the most important factor is understanding your specific needs.
For those venturing into high-temp materials, consider your part size, volume requirements, and level of expertise. Sometimes, simpler materials like polycarbonate or carbon fiber nylon can achieve the same results without the complexity and cost of PEEK or ULTEM.
