SLA (Stereolithography)

Stereolithography (SLA) produces components using a precise UV laser to cure and solidify thin layers of a photo-reactive resin. One of the most accurate 3D printing technologies, SLA is ideal for concept models, rapid prototypes, master patterns, form and fit studies, and investment casting patterns. SLA parts can be clear, and can be finished in multiple ways to meet your needs, including painting, plating, and the installation of threaded inserts or other components. In addition, we can section and bond multiple pieces of a larger part design quickly and seamlessly to create oversized models.

Benefits: Superior surface finish with multiple finishing options. Fast lead times.

Lead Time: Most SLA projects ship out in a standard lead time of 3 – 5 business days, but this can often be expedited if necessary.

Tolerances: SLA prototypes can achieve tolerances of +/- .005” for the first inch, plus an additional +/- .002” for each additional inch.

Build Layer Thickness: Standard resolution parts are built with layers that are .005” - .006” thick. High resolution builds are closer to .002” - .004” thick.

Recommended Minimum Feature Size: Standard resolution parts have a recommended minimum feature size of .025” - .035”, while high resolution builds can produce features as small as .010” - .015”.

Single piece build size is as large as 29" x 25" x 21" however, larger components can be printed in sections and bonded together using actual resin to create a seamless assembled part.
