EX-450HR · High Rigidity and Fine Detail

SpiderMaker EX-450HR is an engineering UV resin characterized by high rigidity, fine detail, and good flow. It is suitable for functional parts that require structural support together with precise surface and geometric detail.

The material is suitable for industrial fixtures, structural prototypes, mechanical parts, equipment accessories, and highly detailed functional models. Printed parts may still shrink depending on model size, geometry, exposure, and post-curing conditions. For assembly tolerances, print a test part first.

For Fixtures, Structural Prototypes, Mechanical Parts, and Highly Detailed Functional Models

In-House R&D · Made in Taiwan

SpiderMaker develops the EX-450HR 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.

SpiderMaker EX-450HR Features

High-Rigidity Structure

A tensile modulus of 2078 MPa and flexural modulus of 2531 MPa provide structural support for functional parts.

Fine Detail

Provides clear reproduction of small structures, edges, and surface textures.

Good Flow

The resin flows readily around the build platform and fine model details, supporting stable printing and easier cleaning.

Strength and Detail

A tensile strength of 42.7 MPa and flexural strength of 81 MPa support both engineering structure and detailed appearance.

Suitable for Prototypes and Fixtures

Suitable for industrial fixtures, structural prototypes, mechanical parts, equipment accessories, and other rigidity-focused applications.

Broad 405nm Compatibility

Compatible with Phrozen, Elegoo, Anycubic, and other 405nm LCD / DLP UV resin printers.

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 resin color, 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, post-cure it evenly under UV light for 30 minutes.
  4. Rotate thick-walled, deep-hole, or complex parts so all surfaces receive more even UV exposure.

Use and Storage

  • Shake or stir the resin thoroughly before use to prevent pigments or other components from settling and affecting print results.
  • For assembly tolerances or dimensional fits, print a test part first and adjust the model according to actual shrinkage.
  • 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.
