Formlabs Tough 1000 V1 Resin for Form 4, 5L

Formlabs Tough 1000 Resin — Reliability and Durability for Functional Parts

Formlabs, a leader in additive manufacturing, presents Tough 1000 Resin — a breakthrough material that sets a new standard in 3D printing functional and durable parts. This innovative photopolymer is designed to provide properties comparable to the widely used high-density polyethylene (HDPE), known for its exceptional strength and resistance to wear. Developed to achieve high strength, stiffness, and impressive resilience, Tough 1000 Resin is the ideal choice for engineers and designers who need parts capable of withstanding significant loads, impacts, and repeated wear cycles. The material is specifically optimized for use with Form 4 series printers, guaranteeing maximum efficiency, precision, and stability in the 3D printing process.

Engineering Reliability: Wear Resistance and Minimal Friction

High Ductility and Impact Strength

Tough 1000 photopolymer is engineered to noticeably outperform traditional engineering plastics. The material boasts an impressive elongation at break — up to 180% — and a Gardner impact strength of 128 inch-pounds, making it an optimal choice for parts that need to repeatedly flex, compress, or deform without the risk of failure. In these characteristics, it surpasses even standard HDPE. The new formula leverages the advantages of the Form 4 platform: fracture toughness is increased by 5 times, elongation at break by 2 times compared to Durable Resin, and it also features improved heat deflection, creep resistance, and durability metrics. The product is available in two volumes: 5 liters and 1 liter.

Outstanding Fatigue and Wear Resistance

This photopolymer is designed for effective performance under constant mechanical stresses. Functional elements — such as hinges or flexible mechanisms — are capable of withstanding prolonged cycles of repetitive stress due to a high work of fracture, reaching 3200 J/m², and a Ross fatigue rating of over 100,000 cycles at 23 °C. Additionally, the material possesses sliding properties comparable to Delrin (POM), which provides a naturally low coefficient of friction and high wear resistance. Thanks to this, the photopolymer is particularly well-suited for assemblies with sliding surfaces — such as gears, hinges, and various types of fasteners, where minimizing friction, scratches, and abrasion is important.

Areas of Application for Tough 1000 Photopolymer

Reliability for High-Stress Parts

The combination of strength, stiffness, and high ductility makes Tough 1000 Resin a versatile engineering material. Its environmental stability helps prevent warping and sagging of parts, including those with complex geometries, ensuring reliability in final use. This photopolymer is recommended for the following tasks:

• Components requiring a strength and stiffness profile comparable to HDPE.
• Impact-resistant jigs and fixtures designed for long-term use in production environments.
• Flexible elements and mechanisms capable of withstanding multiple bending cycles.
• Low-temperature assemblies and durable sliding surfaces — such as hinges or elements subjected to constant friction.

Key Mechanical Properties

Post-Processing Recommendations

For parts to achieve their full strength and functionality, post-processing of engineering and specialty photopolymers, including Tough 1000 Resin, is essential. The process, which completes the chemical reaction, requires a post-curing unit (or an equivalent) such as Form Cure V2. Before curing, the main step is washing: excess photopolymer must be removed by washing with alcohol or ether. For the best surface finish, Formlabs recommends allowing washed parts to air dry for at least 30 minutes before handling or proceeding to the curing stage.
