Are you tired of printing toys and trinkets and ready to venture into the realm of industrial-grade materials in 3D printing? The good news is that the capability is there, allowing you to turn your imagination into reality. While consumer 3D printing has been in the spotlight for a few years, focusing on basic materials like PLA and ABS, the industrial and scientific sectors are now embracing metals and high-performance polymers. Today, we’ll explore the key differences between these two worlds and how to get started with functional 3D printing.
Filaments: From Basic to Engineering Thermoplastics
The first major difference between hobbyist and functional 3D printing lies in the choice of filaments. Hobbyists often use easy-to-print materials like PLA, ABS, and PETG to create simple items. However, the world of functional 3D printing is all about engineering thermoplastics. These include nylon, polycarbonate, and high-temperature chemically resistant polymers like PEEK, Ultem, or PEI. While hobbyist materials are forgiving and suitable for simple projects, high-performance polymers come with a higher learning curve and demand more precision.
Additionally, functional 3D printing requires larger spools of filament, which can be expensive, but the resulting parts are far stronger and more resistant to heat, chemicals, and radiation. To handle these materials, you’ll need additional equipment, such as heated chambers and filament dryers.
Printers: From Entry-Level to High-Performance
The choice of 3D printer is another key difference. Hobbyists often opt for affordable machines, some of which may cost less than $200. However, these budget printers require a significant amount of time for fixing issues, tuning, and achieving satisfactory results. They may suffer from problems like unlevel beds, accuracy issues, and low power levels, which you’ll need to address to get good prints. While you can upgrade these machines to become more robust, it requires time, expertise, and additional expenses.
High-quality basic printers, such as Prusa, Ultimaker, or LulzBot, range from $1,000 to $5,000. These printers are well-tuned for basic materials and offer a simpler user experience compared to budget models. High-performance 3D printers are designed for the industrial world and can cost anywhere from $7,000 to $150,000 or more, depending on the specific requirements. They come with features like heated chambers, hot ends capable of exceeding 500 degrees Celsius, and highly accurate motion systems.
While you can use a budget printer to print high-performance materials like PEEK, investing in a high-quality printer will save you time and provide better results, especially for large and complex prints.
Part Production: From Hobby to Industrial-Grade
Hobbyist 3D prints are typically made from materials like PLA, which are easy to work with and suitable for items around the house, toys, or props. However, they may not withstand extreme conditions. For functional 3D printing, you can create industrial-grade parts that can resist harsh environments. For example, you can produce a small filter that can withstand sulfuric acid at 200 degrees Celsius or structural parts for testing pressures in an oil well.
Tuning: The Art of Precision
Tuning is a critical aspect of 3D printing, and it can be challenging. The cheaper the printer, the more operator skill it demands. More expensive machines, like those from Stratasys, come with software that optimizes the printing process, making them easier to use. Open systems like the Cincinnati 3D printers require users to learn slicing options and understand material behaviors. Hobby printers, like the Prusa, offer a more straightforward experience with automatic settings, while advanced materials require more attention to detail.
Tuning is a creative process, and it involves selecting the right settings, often from hundreds of options, to achieve an optimized print. Each part may have specific requirements, and you’ll need to fine-tune the settings accordingly. Tuning is an iterative process that involves printing, identifying issues, making adjustments, and printing again. Depending on the complexity of the part, this process can take anywhere from one to ten attempts.
The Mindset for Innovation
Lastly, it’s essential to embrace a different mindset when entering the world of functional 3D printing. While hobbyists often print existing designs or accessories, functional 3D printing is about creating innovative solutions to old problems. It’s about re-engineering parts to make them more efficient and solving previously impossible challenges.
The world of manufacturing is rapidly evolving, and functional 3D printing is at the forefront of this transformation. If you’re considering taking your 3D printing to the next level, feel free to reach out for guidance and explore the possibilities of additive manufacturing.
Conclusion
Functional 3D printing opens the door to a new realm of possibilities, bridging the gap between hobbyist and industrial applications. With the right equipment, materials, and mindset, you can create functional and high-performance parts that address real-world challenges. It’s an exciting journey into the future of manufacturing, where innovation knows no bounds.
