Choosing the Right Industrial 3D Printer: Essential Features

The world of industrial 3D printing is rapidly evolving. Selecting the right printer for your specific needs can be a complex process. This article will guide you through the essential features to consider when choosing an industrial 3D printer, helping you make an informed decision.

Understanding Your Needs
Before diving into technical specifications, it's important to evaluate your specific requirements. Ask yourself:
• What materials will you be using? Different 3D printers support different materials, ranging from standard plastics to high-performance polymers like PEEK and PEI. Consider the temperature requirements and mechanical properties your applications will need.
• What are your production goals? Are you focusing on rapid prototyping, small batch manufacturing, or end-use parts? Your production volume and desired speed will impact your printer choice.
• What is your budget? Industrial 3D printers’ range in price. It is important to balance your desired features with your budget.
• What size parts do you need to print? Some printers offer a large build volume for creating bigger parts. Others focus on smaller, high precision components.

Key Features to Consider
Once you have a clear understanding of your needs, you can start evaluating specific printer features.
1. Material Compatibility
The first thing to consider is the range of materials a printer can handle.
• High-Performance Polymers: If your application requires materials like PEEK, PEKK, PEI, or PPSU, you will need a printer with a high-temperature chamber and extruder.
• Engineering-Grade Materials: For materials such as PA-CF, PC, ABS, or ASA, ensure the printer has the correct temperature controls.
• Open Material Systems: Printers that offer an open material system allow you to use a wider range of filaments from various manufacturers, offering versatility and cost-effectiveness. INTAMSYS printers, for example, are not locked to specific brands.
2. Print Speed and Throughput
Industrial applications often demand high-speed printing.
• High-Speed Capabilities: Look for a printer designed for high-throughput printing with capabilities over 500 g/day. Some advanced printers can achieve 1000g/day or more.
• IDEX Systems: An Independent Dual Extruder (IDEX) system can significantly improve printing efficiency. IDEX allows for duplicate and mirror printing modes, doubling capacity. It also allows for support material printing and dual-color prints.
• Reliability: Consistent, full-size prints are important. Look for a printer with validated operation hours and a history of producing a high number of parts without issue.
3. Thermal Management
Thermal management is critical for print quality, especially when using high-performance materials.
• Heated Chamber: A heated chamber maintains a consistent temperature, preventing warping and ensuring dimensional accuracy.
• Heated Build Plate: A heated build plate helps with bed adhesion, a critical factor for printing success.
• High-Temperature Extruder: For high-performance materials, a high-temperature extruder with an all-metal hot end is essential.
4. Build Volume
The build volume will determine the maximum size of the parts you can print.
• Large Format Printing: If you require large parts, consider a large-format printer that will allow you to print them without the need for assembly.
• Desktop Size: Some industrial 3D printers offer industrial performance in a convenient desktop size.
5. Precision and Accuracy
High precision is a must for many industrial applications.
• Auto Leveling: An auto-leveling feature will ensure the print bed is flat, improving print quality and success rate.
• Z-Axis Calibration: Automatic Z-axis calibration makes setup easier and improves printing efficiency.
• Layer Height: FDM printers have a typical layer height between 50 and 400 microns. Smaller layer heights produce smoother parts, while taller layers enable faster print times.
6. Software and Connectivity
The software that comes with your printer and its connectivity capabilities can greatly affect usability and efficiency.
• User-Friendly Software: Look for software that is easy to use with features like automated slicing, model design, and online monitoring.
• Remote Networking: Seamless integration with a Manufacturing Execution System (MES) will help with industry 4.0 initiatives.
• File Transfer: Printers that offer multiple options for file transfer such as Wi-Fi, ethernet and USB connections improve efficiency.
7. Reliability and Support
Reliability and support are key for minimizing downtime and maximizing productivity.
• Continuous Printing: Look for a printer that can operate continuously for long periods without issues.
• Filament Management: Features like filament runout sensors and sealed, dried hoppers can ensure printing consistency.
• Customer Support: It's important to choose a company that offers reliable support and a true partnership.
8. Safety Features
Safety is important in an industrial setting.
• Air Filtration System: A built-in air filtration system with HEPA filters and activated carbon can capture small particles and absorb volatile chemicals.

Conclusion
Choosing the right industrial 3D printer requires a clear understanding of your specific needs and careful evaluation of key features. To make a good choice, think about material compatibility, print speed, thermal management, and build volume. Also consider precision, software, reliability, and safety. This will boost your manufacturing abilities and give you a solid return on your investment
