What is Stereolithography 3D Printing?

Stereolithography (SLA) is an industrial 3D printing process which offers the industries best precision and speed, with minimal need for support structures. Our SLA machines enables the production of intricate parts with tight tolerances, making it suitable for a range of demanding industries such as aerospace, automotive, robotics, consumer products and high quality visual prototypes. Its efficiency, high quality surface finish and versatility make SLA a valuable technology in both rapid prototyping and end-use manufacturing applications alike.

Forge Labs uses 3D System's industrial SLA machines which offer the largest build envelopes commercially available, able to produce parts up to 1500 mm (59 inches) in a single build.  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.

Design Guidelines | Stereolithography
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.
Image

Maximum Build Volume

1500 x 750 x 550 mm (59 x 30 x 22 in.)

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 50-200 um depending on the size of your part. This makes SLA well-suited for producing large, complex parts or for batch production of smaller parts with exceptional accuracy and surface finish.

Image

Tolerances

±0.2%, with a lower limit of ±0.2 mm

Stereolithography is capable of achieving very high levels of dimensional accuracy and precision, allowing for the production of parts with very tight tolerances. Generally, SLA printers can achieve tolerances of around +/- 0.2mm or better.  Achieving high tolerances with SLA printing requires additional calibration and design attention.  Factors such as part geometry, printing orientation, and support structures can all affect the final accuracy and precision of SLA printed parts.

Image

Layer Height

25 - 100 Microns
The layer height is dependent upon  the specific requirements of the part being printed, balancing the need for precision and detail with the need for speed and efficiency and therefore varies  depending on the size of the part being printed. For most parts under 15 inches, the standard layer height used is 100 microns.  
Image

Surface Finish

Uniform, Smooth
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.

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.

Why Use Stereolithography

Industrial Stereolithography (SLA) 3D printing is highly advantageous for industrial applications. It offers high accuracy and precision, excellent surface finish, material versatility, the ability to create complex geometries, fast printing speed, high resolution, and cost-effectiveness for low to medium batch production. SLA enables the production of intricate parts with tight tolerances, making it suitable for industries such as aerospace and automotive. Its efficiency, versatility, and ability to produce high-quality prints make SLA a valuable technology in additive manufacturing.
