Solid Filament

Solid filament gives your 3D prints the strength, precision, and durability they deserve. At Siraya Tech, we’ve engineered a collection of high-performance solid filaments built for makers who demand more from every layer. 

Our solid filament lineup blends advanced materials like ASA-GF, PET-CF, and ABS-CF—each reinforced with glass or carbon fiber—to create prints that stay strong, resist warping, and hold up under heat, UV, and stress.

Perfect for FDM 3D printing, these filaments make professional-grade results accessible to every creator.

Build Stronger, Smarter Prints That Last

These solid filaments are designed to perform where ordinary materials fail. They’re made for reliability, precision, and endurance.

Reinforced Strength That Works as Hard as You Do

Each filament in this collection is infused with glass or carbon fiber to boost stiffness and impact resistance.

• Withstands heavy loads and mechanical stress without cracking.
• Keeps its structure even in high-temperature environments.
• Ideal for automotive, industrial, and outdoor applications.

Dimensional Accuracy Every Time

Solid filaments from Siraya Tech minimize warping and shrinkage for consistent, precise prints.

• Enhanced dimensional stability ensures complex parts fit perfectly.
• Reduced deformation during printing means less post-processing.
• Perfect for detailed designs, tight tolerances, and multi-part assemblies.

Designed for Harsh Environments, Built for Real-World Use

Siraya Tech’s solid filaments go beyond aesthetics—they’re made to last through heat, sunlight, and time.

UV and Weather Resistance That Outlasts the Elements

Our ASA-based and PET-based solid filaments resist fading, aging, and brittleness caused by UV exposure.

• Maintains color and strength outdoors for long-term use.
• Reliable for signage, outdoor fixtures, and automotive parts.
• Keeps your prints stable and vibrant even under harsh weather.

Thermal Stability That Doesn’t Back Down

High glass transition and heat deflection temperatures give these materials exceptional heat resistance.

• Performs steadily in industrial and high-heat applications.
• Maintains form and function under continuous stress.
• Perfect for high-temp mechanical parts and enclosures.

Easy to Print, Ready to Perform

Even with their advanced composition, Siraya Tech solid filaments are optimized for smooth FDM printing.

Reliable Printing for Every Setup

• Works best with direct-drive extruders for consistent flow.
• Recommended printing temperature: 250–270°C with a heated bed.
• Use hardened steel or tungsten carbide nozzles for longevity.

Simple Preparation, Professional Results

• Dry before use to ensure clean extrusion.
• Minimal warping means less wasted material.
• Achieve professional-grade prints without complex tuning.

FAQs on Solid Filaments for 3D Printing

Is PETG more solid than PLA?

Yes, PETG is generally more solid and durable than PLA. It offers better impact resistance and flexibility, making it less likely to crack. PETG also handles heat and stress better, which makes it ideal for functional parts that need more toughness than PLA.

Is PETG FDA approved?

Some PETG materials are FDA compliant, but not all. If you need food-safe 3D prints, check the manufacturer’s certification. Even with FDA-compliant PETG, ensure proper printing conditions and post-processing to maintain safety.

What is hard filament?

Hard filament refers to 3D printing materials that produce rigid, durable parts—like ABS, PETG, ASA, or carbon fiber-reinforced blends. These filaments resist bending, heat, and wear, making them ideal for mechanical and structural applications.

Is PLA or PETG better for food?

PETG is typically better for food-related prints because it’s more resistant to moisture and chemicals. PLA can degrade faster and may absorb bacteria. Always verify if the specific filament is food-safe before using it for utensils or containers.

Can solid filament be used outdoors?

Yes, solid filaments like ASA-GF and PET-CF are great for outdoor use. They resist UV damage, heat, and weathering, keeping prints strong and vibrant even after long exposure to sunlight and changing conditions.
