Resin catalogue for Form 4L

Only materials the manufacturer lists as compatible with Form 4L. In stock: 4 resins.

Nominal build volume: 353 × 196 × 350 mm. Layers from 25 µm depend on the resin and profile. Supports and orientation reduce the space available for a part.

Visual models and prototypes

Resins for assessing shape, presentations and successive design iterations. We select colour and finish for the surfaces that need to be visible.

Grey Resin V5in stock
Default prototype model. Matte grey clearly shows shape and shadow.
Price on request: Grey Resin V5 Compatibility source
Precision Model Resinin stock
Matte beige resin for models and patterns with fine features. Critical dimensions and inspection scope are agreed for the specific part.
Price on request: Precision Model Resin Compatibility source
White Resin V5sourced to order
Models for photography and presentation, base for painting.
Price on request: White Resin V5 Compatibility source
Black Resin V5sourced to order
Black panel and enclosure models. Gloss and support marks are addressed in the agreed finish specification.
Price on request: Black Resin V5 Compatibility source
Fast Model Resinsourced to order
Models for quick shape assessments. We confirm lead time after preparing the file.
Price on request: Fast Model Resin Compatibility source
Color Base Resinsourced to order
Model in a specified color without painting, with pigment mixed into the resin before printing.
Price on request: Color Base Resin Compatibility source

What we assess (3)

Mechanically loaded parts are assessed separately; material is selected for the geometry and operating conditions.
Sustained UV exposure needs assessment. We do not declare colour stability without testing.
The Color Base color applies to the resin before printing; this is a different technique than deep-coloring of sintered powder, which we use to color SLS parts.

Transparent

Clear V5 can be used for a cover or flow model with internal viewing. Clarity depends on thickness and the agreed finish.

Clear Resin V5in stock
Demonstration channels and chambers, light covers and covers with internal viewing.
Price on request: Clear Resin V5 Compatibility source

What we assess (3)

We agree the required clarity and visible surfaces before printing. Additional sanding, polishing or coating may require a separate quote.
Lenses with specified optical performance are outside our service scope.
We do not declare UV resistance or unchanged clarity over time.

Tough resins for functional trials

Materials for assembly prototypes and functional trials. Snap-fits, fits and impact resistance are assessed for the specific geometry.

Tough 2000 Resin V2in stock
Prototype enclosures and brackets for assessing assembly and behaviour under load.
Price on request: Tough 2000 Resin V2 Compatibility source
Tough 1500 Resin V2sourced to order
Prototypes of flexible features and snap-fits. Deflection range and cycle count are assessed on the part.
Price on request: Tough 1500 Resin V2 Compatibility source
Tough 1000 Resinsourced to order
Prototypes for impact and deformation trials under agreed conditions.
Price on request: Tough 1000 Resin Compatibility source

What we assess (3)

Sustained load, temperature and creep require assessment for the selected resin. A short trial does not establish service life.
We compare batch costs after arranging the models. Geometry, quantity, material and finishing matter; there is no universal SLA/SLS break-even quantity.
Supports can leave marks on several surfaces. We agree their placement and finishing around fits and visible faces.

Stiff, glass-filled resins (Rigid)

Glass-filled resins for stiff prototypes and tooling. Deflection and distortion of flat surfaces are assessed for the geometry and print orientation.

Rigid 4000 Resinsourced to order
Prototype brackets, holders and enclosures where limiting deflection matters.
Price on request: Rigid 4000 Resin Compatibility source
Rigid 10K Resinsourced to order
Stiff inspection tooling and masters. We agree the dimensions to inspect before printing.
Price on request: Rigid 10K Resin Compatibility source

What we assess (3)

Stiffness does not establish impact resistance. Thin edges, notches and dynamic loads require separate assessment.
We account for surface finishing and support-mark removal in the quote for the specific part.
For repeatedly flexed parts, we compare resin with PA11 or TPU 90A. Durability requires a trial at the specified deflection and cycle count.

Temperature and special conditions

Items requested with specific requirements: higher operating temperature, flame retardancy requirement, or electrostatic charge dissipation. We supply all of these to order.

High Temp Resinsourced to order
Prototypes for thermoforming and equipment that will be exposed to elevated temperatures.
Price on request: High Temp Resin Compatibility source
Flame Retardant Resinsourced to order
Components in built-in installations where material flame retardancy is required.
Price on request: Flame Retardant Resin Compatibility source
ESD Resinsourced to order
Equipment for electronics with electrostatic charge dissipation.
Price on request: ESD Resin Compatibility source

What we assess (3)

TDS results apply to the stated resin version and specimen preparation. Washing and curing profiles follow the material documentation.
Technical ceramics remain outside our offering. Alumina 4N has no validated Form 4L profile in the manufacturer documentation we checked.
We do not declare compliance with any flammability or ESD standard for the finished product: this is a property of the material as tested by the manufacturer, not a certificate of our process.

Flexible resins

Materials for soft prototypes of grips, covers and seals. These are elastomeric resins; we do not claim they are silicone or that they replace it under all conditions.

Flexible 80A Resin V2sourced to ordernew in catalogue
Flexible covers and grip models for fit and deformation trials.
Price on request: Flexible 80A Resin V2 Compatibility source
Flexible 50A Resinsourced to order
Soft ergonomic models and seal prototypes. This formulation was previously named Elastic 50A Resin V2.
Price on request: Flexible 50A Resin Compatibility source

What we assess (3)

For seals and cyclically loaded parts, we assess deflection, temperature and contact with the working medium. Comparison with TPU 90A requires the operating conditions of the specific part.
Supports and their marks are assessed for the geometry. Sealing and contact surfaces must be identified before printing.
Hardness does not establish finishing time or durability. We confirm washing, curing and finishing for the selected resin.

Patterns for metal casting

Burnout patterns for metal investment casting. We agree the material, pattern construction and preparation with the foundry before printing.

Castable Wax Resinsourced to order
Fine-detail patterns for investment casting. We agree the burnout schedule with the foundry.
Price on request: Castable Wax Resin Compatibility source
Clear Cast Resinsourced to order
Patterns for metal investment casting. They require a hollow or latticed interior and drain holes following the manufacturer guidelines.
Price on request: Clear Cast Resin Compatibility source

What we assess (3)

A casting pattern is a semi-finished product. We do not perform the actual casting; we transfer the model to a foundry.
Casting dimensions depend on the pattern, mould and foundry process. We agree pattern inspection scope and do not declare finished casting tolerances.
Geometry, casting material and quantity determine the process choice. We do not apply one quantity threshold to every project.

Sources: Formlabs, material catalogue and documentation, checked 12 October 2026; machine compatibility: Formlabs, Form 4L print profiles and product compatibility sections, checked 12 October 2026. Compatibility does not mean immediate availability. We confirm resin, print profile and lead time when quoting.

SLA / resin and process

From resin to a finished part

Part properties also depend on orientation, supports, washing and curing. Choose a resin for its application and technical data. Your model and requirements help us assess how to make the part.

Datasheets with test methods

4 of 19 resins

Transcribed from manufacturer TDS documents. For other resins, we select the applicable datasheet and profile before confirming the order.

What we do not print

We do not produce dental or medical devices or provide those services, or accept safety-critical parts. Precision Model Resin in our catalogue is used only for technical models and masters. The manufacturer's resin classification does not qualify our process for use in patients.
