MatterHackers Protopasta Galactic Empire Purple Metallic HTPLA Filament - 1.75mm (0.5kg)

When Reliability Counts - Be a PRO

MatterHackers PRO Series filament is all about quality. When the performance of a 3D printed component is the ultimate goal, you need to know you’re printing with a material you can trust. MatterHackers’ PRO Series filament is meticulously refined and continuously tested to provide optimal results for every application. That’s why our material experts have developed a range of responsive high-performance thermoplastics that maintain reliability through your process of rough prototyping to sophisticated, end-use designs. No matter your end goal, PRO Series filament delivers your parts exactly as you intended them.

Function in its Finest Form 

MatterHackers PRO Series materials are formulated for functional 3D printing. Because of its precisely detailed chemical blueprint, PRO Series 3D printing filament provides the consistency needed for repeatable part-production. Kawasaki’s Supercross Racing Team Engineers use PRO Series materials for both prototyping and end-use parts. Using PRO Series materials for essential components on their teams’ motorcycles has not only helped them fabricate in low volume, but it’s also reduced cost by 95% and time by 86%. They turn to PRO Series because they know it works well.

Premium Quality and Craftsmanship

PRO Series materials are formulated with zero compromises. The base resin, and all performance-enhancing additives, are carefully sourced to include only those of the highest purity and provenance The consistent colors curated from quality sources combined with the exact manufacturing environment needed to maintain an industry-leading ±0.02mm diameter tolerance create materials you can use confidently. Experience smooth, uniform filament for all your important projects - experience PRO Series.

PRO Series PETG is a well-balanced material with good printability and chemical resistance

It’s Not Just Filament, It’s a Results-Driven Experience - With Options

Not only is our PRO Series line of filament carefully crafted, but we have an extensive collection of materials to choose from that fit every need and specific applications. From Tough PLA for serious prototyping to vibrant Nylons for sturdy, lasting products, PRO Series 3D printing materials deliver quality parts, time after time. PRO Series filament is created with end-use results as the main priority, ensuring that your finished 3D printed parts are as clean, sturdy, and functional as possible.

Choose the material developed and guaranteed by the leader in 3D printing materials

MatterHackers PRO Series filament has remained the quintessential choice for anyone that demands exacting results for their business, products, and projects. Our attention to precise filament tolerance, strict coloration guidelines, and definitive chemical patterns are reflected directly in your completed products.

Mechanical Properties that are Tuned for Performance 

We know that end-use products are only as good as the materials and tools used to create them - that’s why we put our PRO Series filament through rigorous testing before it makes its way to your workshop or manufacturing floor. Having high-quality materials is essential when creating functional or product-ready components, therefore all MatterHackers PRO Series materials are analyzed using in-house testing equipment, including a Universal Testing System and a Melt Flow Indexer. These machines are used specifically to measure tensile and flexural properties, as well as the melt flow index of each material ensuring that all PRO Series filament is dependable and performing at its peak capabilities. MatterHackers PRO Series materials are tested and measured using ASTM 638 and D790 or ISO 527-1, 527-2, and 178.

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.

Vibrant Color Consistency You Can Rely On

Rest assured knowing that MatterHackers controls and actively analyzes the compounding and coloration of each filament batch, ensuring that your projects are the same from spool to spool. Color continuity between batches is controlled and confirmed with a color-analyzing spectrometer running in line during filament production. Your PRO Series filament will always be the same color PRO Series filament.
