Pro Series Natural PRO Series PPS Filament - 2.85mm (0.75kg)

Pros and Cons of PRO Series PPS

PPS (Polyphenylene Sulfide) offers a balance of outstanding performance and challenges, making it a material best suited for advanced and technical applications. Its exceptional properties, including chemical resistance and high-temperature stability, are complemented by the need for careful preparation and handling.

• PPS excels in chemical resistance, thermal stability, and electrical insulation, making it ideal for demanding applications.
• Preparation is critical, as the material requires drying and specific adhesives for optimal printing.
• Its high performance comes at a higher cost and requires careful handling to avoid warping and support removal challenges.

Tips for Successful Printing

To achieve optimal results with PPS, careful preparation and environmental control are essential. Keeping the filament dry and maintaining a stable heated environment ensures strong mechanical properties, dimensional accuracy, and proper layer adhesion.

• Dry the filament for at least 4 hours at 110°C before printing to preserve its mechanical properties.
• Use an enclosed and heated chamber with a minimum temperature of 65°C to prevent warping and ensure proper crystallization.
• Store the filament in a dry box to minimize moisture absorption during and after use.

Importance of a Heated Chamber

Printing PPS requires an actively heated chamber to maintain a stable temperature of 65°C or higher. This controlled environment prevents issues like deformation and cracking while ensuring the material’s mechanical properties and precision are preserved.

• A heated chamber reduces deformation and improves dimensional accuracy by maintaining stable temperatures.
• Proper heating ensures strong layer adhesion and preserves the material’s crystallization and strength.
• Prevents premature cooling of fibers, avoiding extrusion issues and ensuring a smooth printing process.

Quality Assurance: Why Filament Diameter and Ovality Matters

With PRO Series materials, you know you’re getting the most accurate filament diameter and ovality available. Having a consistent diameter of 3D printing filament is very important - it directly impacts the print quality of your designs. The slicing engine calculates the volume of filament that will be deposited on each layer. The critical value that is input into the slicing engine for that volume is the diameter of the material (either 1.75mm or 2.85mm). Therefore, any variation in that diameter can cause the print to over or under extrude. In terms of raw materials - the filament diameter is one that requires a high level of confidence that you KNOW what you’re using.

MatterHackers Maintains  Diameter Tolerance In Every Spool using Laser Gauges

Since we know diameter matters, we obsess over ensuring that PRO Series materials are on the mark so you can create perfectly printed parts. MatterHackers uses two and three-axis laser systems to measure and maintain the accuracy of the filament diameter at 40 hertz (40 times per second) - that way we know the filament diameter is consistent and within our 0.02mm diameter tolerance guarantee. Not only that, but the data for each production run is recorded and stored so we have traceability on all PRO Series materials to establish further confidence in each batch we produce.
