Tough-250 Super Tough Engineering UV Resin | Gray 1Kg

Product Information

Actual printing and post-curing results may vary with printer light intensity, release-film condition, model structure, ambient temperature, and post-curing equipment.

Tough-250 · Ultra Toughness and Exceptional Drop Resistance

SpiderMaker Tough-250 is an ultra-tough engineering UV resin developed for high-impact, drop-resistant, and deformation-tolerant applications. Its unnotched Charpy impact strength exceeds 125 kJ/m², helping printed parts resist brittle failure when dropped or struck. It is especially suitable for functional parts that require repeated use and impact resistance.

With 33.7% elongation at break, the material combines good ductility with structural support. It is suitable for snap-fits, fasteners, drop-resistant housings, mechanical parts, and printed parts that require drilling or tapping. For assembly tolerances, print a test part first to confirm actual shrinkage and fit.

In-House R&D · Made in Taiwan

SpiderMaker develops the Tough-250 formulation in-house and manages production and quality control in Pingzhen, Taoyuan, Taiwan. Raw-material selection, formulation, color control, and product inspection are all handled by its professional team.

Recommended Applications

Technical Data Sheet

Test data were obtained from specific specimens and post-curing conditions. Actual part performance may vary with printer, exposure, model structure, print orientation, wall thickness, and post-curing uniformity.

Print Settings

Published settings are based primarily on a 0.05 mm layer height and Phrozen printers. Exposure, lift, and retract settings should still be adjusted according to light intensity, release-film condition, model size, and ambient conditions.

Washing and Post-Curing Recommendations

1. After printing, remove uncured surface resin with alcohol or isopropyl alcohol.
2. Avoid prolonged soaking. After washing, make sure liquid on the surface, in holes, and inside the part has completely evaporated.
3. After the part is completely dry, evenly UV post-cure it for 30 minutes as the initial recommendation.
4. The degree of post-curing affects the final rigidity and toughness. When adjusting post-curing conditions, confirm them with a test part before applying them to final components.

Use and Storage

• Shake or stir the resin thoroughly before use to prevent pigments or other components from settling and affecting print results.
• For snap-fits, threads, hole positions, or assembly tolerances, print a test part first and adjust the model according to actual shrinkage.
• Use suitable tools and feed rates when drilling or tapping, and confirm the machining conditions with scrap material or a test part first.
• This material has an HDT of 49.9°C and is not recommended for prolonged high-temperature exposure or high-temperature load-bearing environments.
• Filter unused resin through a fine filter before returning it to the original bottle to prevent debris from entering.
• Keep the resin away from direct sunlight and other UV sources. Seal the bottle tightly and store it in a cool place.
• Wear suitable gloves and maintain good ventilation when handling liquid resin.
