High Strength Resin

High strength resin from Siraya Tech gives you functional 3D prints that hold up under load and resist bending. This collection includes tough and engineering-grade photopolymer resins formulated for structural parts, industrial jigs, and mechanical components.

Whether you need PC-like impact resistance, high tensile performance, or parts you can drill and tap, there's a resin here built for the job. All resins cure at 405nm and work with LCD, DLP, and SLA printers from Elegoo, Anycubic, Phrozen, Creality, and Peopoly.

Strength You Can Design Around

• Tough resin options deliver high impact resistance so parts survive drops and mechanical shock.
• Engineering resins offer high tensile and flexural strength for load-bearing applications.
• Drillable resin lets you tap holes and insert fasteners after printing.
• Options range from PC-like strength to 50% tougher than standard ABS-like resin.

Validated Properties You Can Trust

• Siraya Tech resins undergo extensive validation to ensure consistent mechanical properties.
• Even shrinkage (about 6% per volume) keeps parts dimensionally accurate.
• Available in multiple formulations so you can match the resin to your part's actual stress profile.
• Mix resins together to fine-tune strength, flexibility, and hardness for specific applications.

Ready for Real-World Use

• Print functional prototypes, end-use parts, and production tooling directly.
• High-temperature resistant options handle up to 250°C without softening.
• Compatible with all standard 405nm resin printers, with downloadable print profiles.
• Bulk sizing available for production runs and frequent use.

Frequently Asked Questions on High Strength Resin

What is the strongest resin for 3D printing?

Strength depends on the type of stress your part will face. For tensile and flexural strength, engineering resins with high modulus ratings perform best. For impact and drop resistance, tough resins are the better choice. The strongest option for your part depends on how it will actually be used.

Is high strength resin the same as tough resin?

Not exactly. High strength resin focuses on resisting bending and holding static load. Tough resin is designed to absorb impact and resist sudden failure. A part that sits under constant pressure needs high strength. A part that gets dropped or knocked needs toughness. Some resins offer both.

Can I drill and tap high strength resin prints?

Yes, certain formulations are designed to be drillable. Build resin shrinks evenly and accepts fasteners well. Use chamfered entries and moderate drill speeds to avoid cracking at sharp corners.

How does high strength resin compare to FDM prints?

High strength resin can match or exceed the tensile and flexural strength of common FDM materials like PLA and ABS. It also produces smoother surface finishes and finer detail. FDM has advantages in larger parts and materials like nylon and polycarbonate for certain applications.

Does high strength resin shrink?

Yes. Most resins shrink about 6% by volume (1.5-2% per axis) when fully cured. Build resin shrinks more evenly and less than most model resins, making it a good choice when dimensional accuracy is critical. Sculpt Ultra has about 2.5% volume shrinkage due to its ceramic composite.
