Formlabs Tough 1000 Resin (Form 4)

A ductile, impact-resistant engineering resin with a feel and performance comparable to HDPE — ideal for strong prototypes and end-use parts that must withstand repeated flexing, wear, and real-world handling, with a smooth, professional finish on the Form 4 Series.

Formlabs Tough 1000 Resin (Form 4) cartridge
Category: Engineering
Technology: SLA
Feel: HDPE-like
Strength: Ductile + tough
Best for: Wear & fatigue resistance

Important: Post-curing is required to achieve intended mechanical performance. Follow validated wash + post-cure settings in manufacturer documentation.

Tough, resilient parts that take impacts, flexing, and everyday abuse

Tough 1000 Resin is designed for parts that need real durability — not just good looks. It’s an excellent pick when you want a material that can deform under load, recover, and keep going without brittle failure.

Use it for functional prototypes, snap-fit housings, wear surfaces, and fixtures where impact resistance, fatigue resistance, and low friction matter. On the Form 4 Series, it delivers fast, repeatable output with a smooth surface finish.

Why Choose Formlabs Tough 1000 Resin?

HDPE-Like Performance

A great option when you need a tough, ductile material that can flex and absorb impacts without brittle cracking.

Wear & Fatigue Resistant

Built for repeated motion and contact — useful for mechanisms, fixtures, guides, and parts that see ongoing handling.

Smooth, Professional Surface

Produce clean parts that look “production-ready” while still delivering real functional performance.

Fast, Reliable Output on Form 4

Designed to take advantage of the Form 4 Series for quick iteration and consistent, repeatable results.

Applications

Tough 1000 is ideal when you want “real plastic” behavior for functional parts, not brittle demo prints.

Consider Tough 1000 Resin for:

  • Snap-fit housings, covers, and enclosures
  • Jigs, fixtures, and assembly aids that get used repeatedly
  • Wear surfaces, guides, low-friction interfaces, and moving mechanisms
  • Durable prototypes for drop/impact testing and functional validation

Design tip: Add generous fillets at stress concentrators and orient parts to reduce peel stress on thin tabs for maximum toughness.

Workflow Overview

Tough 1000 Resin follows a validated print + wash + post-cure workflow. For intended properties, use the recommended preset and follow the manufacturer documentation for solvent handling, wash timing, and post-cure settings.

  • Print with the Tough 1000 preset on your Form 4.
  • Wash using the validated solvent and duration (see manufacturer wash settings).
  • Post-cure to achieve the intended strength/toughness balance.
  • Finish supports carefully, especially on snap-fits and contact surfaces.
