Formlabs Tough 1500 Resin V2 (Form 4)

A polypropylene-like engineering resin for tough, compliant parts — ideal for snap-fits, self-tapping screws, hinges, and resilient jigs/fixtures, with a reliable print–wash–cure workflow on the Form 4 Series.

Formlabs Tough 1500 Resin V2 cartridge (Form 4)
Application: Engineering / Functional Prototyping
Technology: SLA (Form 4 Series)
Comparable: PP-like toughness
Key trait: Pliable + resilient

Workflow note: For best surface finish, allow parts to air-dry after washing before handling, and post-cure Engineering Resins to achieve full strength and functionality (see manufacturer settings PDF below).

Tough, compliant parts that don’t shatter — tuned for snap-fits and screw bosses

Tough 1500 Resin V2 is a resilient engineering material with a balanced blend of stiffness and ductility, designed to simulate polypropylene-like behavior for functional prototypes and production-intent parts.

Built for the Form 4 Series, the V2 formulation delivers substantially higher fracture toughness than the prior version — helping parts survive drilling, tapping, cracking, and repeated flexing.

Why Choose Formlabs Tough 1500 Resin V2?

Tougher Where It Matters

Higher fracture toughness helps parts survive drilling, tapping, cracking, and impact — ideal for thin walls and functional features.

Ductile + Resilient for Compliant Parts

Designed for repeated flexing in snap-fits, latches, hinges, flexures, and dampers — when you need stiffness and bend without shatter.

High Environmental Stability

Built for demanding use with elevated heat resistance for a high-compliance SLA material, plus improved long-term durability.

Reliable Form 4 Workflow

Predictable print + wash + cure results when you follow the manufacturer time/temperature settings and recommended handling steps.

Applications

Tough 1500 Resin V2 is ideal for resilient prototyping or simulating the toughness of polypropylene (PP), especially where parts must flex, snap, or take impact without failing.

Consider Tough 1500 Resin V2 for:

  • Compliant mechanisms — latches, flexures, living hinges, dampers
  • Snap-fits & functional enclosures — rugged housings, covers, protective shells
  • Self-tapping screw bosses — features that won’t crack during assembly
  • Impact-resistant jigs & fixtures — long-term use on the factory floor

*Note: Material properties vary by geometry, orientation, settings, and post-curing. Follow manufacturer post-processing settings for intended performance.

Workflow Overview

Tough 1500 Resin V2 uses a print + wash + post-cure workflow. Post-curing Engineering Resins is essential to reach full mechanical performance.

  • Print with the recommended Tough 1500 V2 preset for your Form 4 Series printer.
  • Wash with the validated wash method/time. Allow parts to air-dry after washing before handling for best surface finish.
  • Post-cure using the manufacturer time/temperature settings for your curing unit to achieve full strength and functionality.
  • Finish (optional): light sanding/media finishing for appearance-critical surfaces.

FAQ

1) What is Tough 1500 Resin V2 best for?

Compliant, impact-resistant engineering parts such as snap-fits, hinges, latches, self-tapping screw bosses, and rugged enclosures — plus jigs and fixtures that see real shop-floor use.

2) Do I need to post-cure this resin?

Yes. Post-curing Engineering Resins is required to reach full strength and functionality. Use the manufacturer time/temperature settings for your curing unit.

3) Which printers is it intended for?

This page is for Form 4 Series configurations. Use the correct preset and validated post-processing settings for best results.
