Why Choose Standard Resin V5?

Formlabs' general-purpose SLA resin offers a dependable default for most SLA printing needs.

Presentation-Ready Surface Finish

SLA cures each layer as part of one continuous solid volume, so parts come off the printer with a smooth, matte surface and no visible layer lines, rivaling injection-molded parts straight out of the box.

Fast, Reliable Workflow

Standard Resin V5 is tuned for fast print speed and high accuracy on Form 4 series printers, so iterations come back quickly without sacrificing dimensional fidelity.

Stiff Without Being Brittle

A tensile modulus of 2.68 GPa keeps parts rigid under load, while 13% elongation at break gives enough ductility to resist cracking during normal handling and assembly.

Standard Resin V5 Color Options

Form Now prints Standard Resin V5 in ten colors: Grey, White, and Black, plus seven premium static colors. All ten share the same SLA process and presentation-ready finish; Grey, White, and Black each have their own mechanical properties, while the seven premium colors share one common specification. Color is selected during part configuration after upload.

Source: Formlabs' Design specifications for 3D models: Form 3/Form 3B, developed using Formlabs Clear Resin at 100 microns; exact minimums vary slightly by resin, printer, and layer thickness. These are general guidelines; thicker cross-sections and part geometry can shift the safe minimums for a specific design. Maximum build size reflects our largest-format SLA printer; actual build size depends on which machine your order routes to.

Frequently Asked Questions

Everything you need to know about designing, ordering, and using Standard Resin V5 parts on Form Now.

What is Standard Resin V5?

Standard Resin V5 is Formlabs' general-purpose stereolithography (SLA) resin, printed on Form 4 series printers. It balances fast print speed, high accuracy, a presentation-ready appearance, and strong mechanical properties, making it the default choice for most SLA prototypes and models.

How strong is Standard Resin V5?

Grey Resin V5 has a flexural strength of 103 MPa, a tensile modulus of 2.68 GPa, and an elongation at break of 13%. This combination gives parts a stiff, rigid feel with enough ductility to resist cracking under normal handling, unlike more brittle SLA materials.

What is Standard Resin V5 used for?

Standard Resin V5 is commonly used for general prototyping, presentation and concept models, form and fit testing, and parts with intricate geometry or fine surface detail where SLA's smooth, layer-free finish matters more than extreme heat or impact resistance.

What color options are available for Standard Resin V5?

Form Now offers Standard Resin V5 in ten colors: Grey, White, and Black, plus seven premium static colors, Signal Red, Orange, Cadmium Yellow, Kelly Green, Cobalt Blue, Royal Purple, and Berry Pink. Grey, White, and Black each have slightly different stiffness, impact resistance, and heat deflection temperature; the seven premium colors share one common specification distinct from the base colors.

What finish do Standard Resin V5 parts arrive in?

Form Now Standard Resin V5 parts ship in the standard finish: support marks removed and lightly sanded, leaving a clean, matte surface. Any additional finish options for a given order are shown during part configuration at checkout.

What are the minimum wall thickness and hole size design rules for Standard Resin V5?

Per Formlabs' SLA design specifications, we recommend a minimum wall thickness of 1.0 mm or more, whether supported or unsupported, for reliably flat, functional walls. Holes should be at least 0.5 mm in diameter, and drain holes for hollow cavities need at least 2.5 mm. Maximum single-part build size is 353 x 196 x 350 mm.

How does Standard Resin V5 compare to FDM PLA?

Standard Resin V5 cures as a single solid volume under laser light, so its mechanical properties and surface finish are consistent in every direction, without the visible layer lines or weak Z-axis layer bonds typical of FDM PLA prints. PLA parts print faster for large, simple geometry, but Standard Resin V5 captures far finer detail and produces a smoother, presentation-ready surface straight off the printer.
