High Detail Engineering Grade Resins

High resolution 3D printing capable of manufacturing parts up to 59 x 30 x 22 inches with incredible detail.

Stereolithography (SLA) is an industrial 3D printing process which offers the industries best precision and speed, with minimal need for support and post processing. Forge Labs uses 3D System's industrial SLA machines which offer the largest build envelopes commercially available, capable of producing parts up to 1500 mm (59 inches).  Layers are cured by ultraviolet laser through a process called vat photopolymerization to solidify the pattern layer by layer. Unlike desktop SLA machines, our parts are produced underneath the resin which dramatically reduces peeling forces. This allows for our parts to be produced with superior mechanical properties, surface finish and accuracy compared to inverted stereolithography.

Manufacturing using Stereolithography (SLA) 3D printing services is ideal for printing high detail prototypes, master patterns, tools, molds, dies, jigs, fixtures or any application where surface finish, accuracy and product aesthetics are critical.

Exceptionally Strong & Durable

Accura Xtreme White (XTW) is an exceptionally tough, and highly accurate industrial grade resin for demanding applications. Accura XTW resin is highly versatile, making it ideal for a number of applications from concept models to functional assemblies that require high fatigue resistance such as snap fits & enclosures. The outstanding surface finish makes it also ideal for creating master patterns for both vacuum casting & molding.

General Purpose Transparent Parts

Accura ClearVue material is a ideal for models requiring high clarity. This transparent material that simulates the properties and appearance of Polycarbonate and ABS. This material is ideal for design validation, water flow testing, and packaging.

Polypropylene Like Material 

Accura 25 simulates the both the material properties and aesthetics of molded Polypropylene. Accura 25 provides excellent surface finish, durability and elongation strength which allows 3D prints of highly accurate and attractive prototypes that test fit, form and function with outstanding accuracy and dimensional stability.

High Temperature Nano Composite 

Accura Bluestone is a high temperature, ultra stiff nano composite ideal for the manufacturing of stable parts. With a post-cure heat deflection of 284°C @ 0.45 MPa, Accura Bluestone is one of the most thermally stable resins available.

Rigid Black Resin

Forge Lab's prototyping resin simulates black ABS articles for functional prototyping and production parts in industrial grade resins. Offering both strength & rigidity for low demand applications where a smooth, black finsh is critical such as concept models and form and fit testing.

Stereolithography (SLA) is one of the oldest manufacturing process that uses a vat of resin, cured by a high powered UV laser to form a solid structure. This design guidelines covers specific design parameters, which will need to be followed to prevent build failures from occurring. We have set the minimum allowed tolerances specified by our engineers and the manufacturer to ensure your parts build successfully and on schedule.

Accuracy

The machine begins curing layers on the surface of the resin, curing each cross section by the set layer height of 50-100 um. After each layer, the parts drops down into the vat of liquid resin which acts as a support structure for the part. The process repeats itself with the top 50-100 um layers of resin being cured selectively by the laser.  Parts are typically produced within +/- 0.2mm for most geometries.

Surface Finish

Parts produced using SLA provide a ultra high detail, uniform finish with little to no visible layer lines. Parts can be easily sanded and painted to offer exceptional aesthetics with minimal effort.  We also offer in-house dying and painting services to take your parts to the next level.

Pricing

Optimizing your designs for Stereolithography help keep manufacturing costs down. Price is primarily based upon the volume of resin consumed to manufacture your parts as well as the X, Y, & Z extents of your part which affect the run-time cost. Small,  hollow parts are priced the most competitively in Stereolithography.  It is important to keep your wall thickness and hollow out any dense sections of your part.

Build Size

Stereolithography offers the largest build volume of any 3D Printing technology with a capacity of: 1500 x 750 x 550 mm (59 x 30 x 22 in.), and a standard layer thickness of 50-100 um depending on the size of your part.
