    Form 4 Resin Tank

    Low Force Display™ (LFD) 3D printing uses a flexible yet strong dual-layer film tank for consistent, high-quality prints. Every resin tank includes a reusable lid, making it easy to stack tanks and store resin outside of the machine. With a separate tank for each individual resin color or type, switching materials is as easy as sliding in a new tank.

    Resin Tanks are built to last and deliver consistent performance for at least 75,000 layers of printing — approximately 190 prints using average height model (39 mm tall), any resin, and 100 µm layer height.

    Form 4 Mixer

    The Form 4 Resin Mixer improves material performance by keeping resin homogenous in the tank during the printing process. A Resin Mixer is required anytime you are printing. Resin Mixers typically last for the lifetime of your Resin Tank or more.

    For convenience, we recommend having one Resin Mixer for each Form 4 Resin Tank.

    Form 3 Resin Tank V2.1

    Low Force Stereolithography (LFS)™ 3D printing uses linear illumination and a flexible film tank to turn liquid resin into flawless parts. A key component of the LFS process, the strong dual-layer film at the bottom of the Form 3 Resin Tank, allows for a dynamic and precise print process.

    Notice: Form 3 Resin Tank V2.1 is compatible with all Formlabs resins, but is required for use with some specific materials. There are two previous versions of the Form 3 Resin Tank, Tank V1 and Tank V2, each with their own compatibility requirements. Read more about all tank versions, compatibility, lifetime, and maintenance in our support article.

A key component of the LFS process, the strong dual-layer film at the bottom of the Form 3L Resin Tank allows for a dynamic and precise print process, scaled up for large format printing.

    Form 3L Resin Tank V3 offers an improved print success rate in some cases compared to the previous version of the Form 3L Resin Tank V2.

Post-Processing

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.

 

SETTINGS

Form Wash | Form Wash L

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.

FAQ

Rigid 4000 Resin is a glass-filled SLA resin that offers similar stiffness to PEEK and PEKK thermoplastics. It holds the highest tensile strength in Formlabs' Engineering Resin Library, with a tensile modulus of 4.1 GPa and an ultimate tensile strength of 69 MPa. Parts print with a smooth, matte finish and are highly resistant to heat and chemicals.

Rigid 4000 Resin is designed to simulate the stiffness of high-performance thermoplastics like PEEK and PEKK. It is resistant to deformation under a variety of forces, pressures, and torques, making it one of the stiffest options in the Formlabs Engineering Resin Library.

Rigid 4000 Resin has a heat deflection temperature of 60 °C at 1.8 MPa and 77 °C at 0.45 MPa, along with a thermal expansion coefficient of 63 μm/m/°C. It is well suited for engineering environments where parts must retain their shape under elevated temperatures.

The complete material properties and handling information are available in the Rigid 4000 Resin Technical Data Sheet, which can be downloaded directly from the Formlabs website.

Rigid 4000 Resin is ideal for stiff, strong engineering-grade prototypes and industrial parts that must withstand significant loads without bending. Common applications include mounts, brackets, jigs, fixtures, thin-walled parts, and prototypes that simulate the stiffness of PEEK.

Yes. Rigid 4000 Resin is categorized for both rapid prototyping and end-use parts. Its combination of high stiffness, thermal resistance, and a smooth, matte finish means parts look and feel like a finished product straight from the printer.

Rigid 4000 Resin is compatible with a wide range of Formlabs SLA printers, including Form 4, Form 4B, Form 4L, Form 4BL, Form 3, Form 3L, Form 3B, Form 3BL, and Form 2.

Yes. Post-curing is essential for Engineering and Specialty Resins like Rigid 4000. This step completes the chemical reaction initiated during printing and transforms the part from its green state into a fully finished component with full strength and functionality.

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.
