Washing
The foundational step in any SLA post-processing workflow is to remove any excess resin on the surface of the parts through an alcohol or ether wash.
For the best surface finish, Formlabs recommends allowing parts printed in Tough 2000 Resin V2 to air dry for at least 10 minutes after washing, before handling.
SETTINGS
Curing
Post-curing Engineering and Specialty Resins is essential for parts to achieve their full strength and functionality. This step completes the chemical reaction initiated during printing, transforming the part from its green state into a fully finished component.

Next-Generation Tough Resins That Rival Thermoplastics

Tough 1000 Resin is a ductile, impact-resistant material with comparable strength, stiffness, and toughness to high-density polyethylene (HDPE), designed with exceptional wear and fatigue resistance for long-term toughness and utility.
The 180% elongation at break (EAB) and Gardner impact strength of 128 in-lb surpass HDPE, making it ideal for parts that bend, compress, or deform without cracking. Hinges and functional parts can handle repeated stress and wear with a work of fracture of 3,200 J/m2 and a Ross flex fatigue of >100,000 cycles (at 23 °C). With a matte, dark grey color, Tough 1000 Resin is engineered for applications that require smooth surfaces and low-friction finishes.
Tough 1000 Resin is a new material formulation that leverages the technology of Form 4 Series printers, with 5x higher fracture toughness, 2x higher EAB, and improved temperature, creep, and aging resistance compared to Durable Resin.

FAQ
Tough 2000 Resin V2 is a rugged SLA 3D printing material with strength and stiffness comparable to ABS. It combines toughness with high temperature and creep resistance, making it well suited for heavy-duty functional prototypes, end-use parts, jigs, fixtures, protective shells, and snap-fit enclosures that must resist shattering, deformation, and long-term wear.
The V2 formulation delivers 3x higher fracture toughness, improved temperature resistance, better material longevity, and enhanced aesthetics compared to the original Tough 2000 Resin. It also features a darker, more matte finish that improves contrast and scratch resistance for presentation-ready parts.
The material matches ABS closely in tensile modulus (both at 1800 MPa) and surpasses it in ultimate tensile strength (40.4 MPa vs. 39 MPa) and elongation at break (79% vs. 8%). Its heat deflection temperature of 70 °C at 0.45 MPa is somewhat lower than the typical ABS range of 80-90 °C noted in literature, so it is best evaluated against your specific application requirements. Download the Tough 2000 Resin V2 Technical Data Sheet for a full side-by-side comparison.
Each material in the Formlabs Tough Resin family is benchmarked against a different thermoplastic. Tough 1000 Resin is the most ductile, comparable to HDPE, with a 180% elongation at break and exceptional wear and fatigue resistance. Tough 1500 Resin V2 is balanced between stiffness and compliance, comparable to polypropylene, and is well suited for compliant mechanisms, latches, and self-tapping screw bosses. Tough 2000 Resin V2 is the strongest and stiffest of the three, comparable to ABS, and is the best choice when high temperature and creep resistance are priorities.

Parts printed at 100 μm on a Form 4 and post-cured with a Form Cure V2 for 12 minutes at 70 °C exhibit the following properties: 40.4 MPa ultimate tensile strength, 1800 MPa tensile modulus, 79% elongation at break, 67 MPa flexural strength, 1701 MPa flexural modulus, 25 J/m notched Izod impact strength, and a heat deflection temperature of 70 °C at 0.45 MPa. Full specifications are available in the Technical Data Sheet.
The material offers exceptional creep resistance, showing only 1.3% creep strain under a 4 MPa load after two weeks. This makes it a reliable choice for structural jigs, load-bearing fixtures, and enclosures that must hold their shape under continuous stress.
Yes. Its 79% elongation at break and high fracture toughness of 305 J/m2 make it well suited for snap-fit assemblies and parts that undergo repeated flexing without breaking. The recommended applications include snap-fit enclosures and robust protective shells.
Post-processing involves two main steps. First, wash the part using isopropyl alcohol or an ether-based solution to remove uncured resin from the surface. Formlabs Form Wash or Form Wash L are both compatible. Second, post-cure the part using a Form Cure or Form Cure L unit. Post-curing is essential for parts to achieve their full strength and intended functional properties by completing the chemical reaction initiated during printing.
Wash time settings are available on the Formlabs support site for Form Wash and Form Wash L. Cure settings are available separately for Form Cure V1, Form Cure V2, Form Cure L V1, and Form Cure L V2.
