Stereolithography (aka SLA or 3D layering or 3D printing) produces three-dimensional solid plastic objects directly from CAD data in a process that utilizes a ultra-violet laser and a large vat of photo-curable polymer liquid plastic. Working from a CAD file, stereolithography solidifies the polymer into precise patterns using a laser beam. Since they are created directly from 3D designs, SLA parts are extremely accurate, and are delivered with fast turnaround time without any compromise in accuracy or quality.

bulletQuickcast Patterns are used as wax patterns for investment casting of metals such as aluminum, steel, bronze, etc. (See Metal Castings).

Finishing types:

2A Finishing: Minimum surface sanding and a bead blast finish. Ideal for engineering check models and form/fit testing 3A Finishing: Each part is sanded and hand-finished, benched, and verified for dimensional accuracy and surface integrity. Ideal for marketing samples, trade show samples and ready for painting. Paint and Texture: Parts are painted and textured to exact color match and specified texture. A 3A finish is required prior to paint and texture.
