The RJM SLA Process

How the SLA Process Works.

Beginning with analyzing the CAD data, RJM will arrange all parts received for an SLA build on an RJM Ultra Hi-Res SLA platform. After arrangement and pre-build checks, RJM then proceeds to the custom support generation. This step ensures the high quality and success rate of the RJM SLA process.

The stereolithography, or SLA, production process is a type of additive prototyping. With this process, CAD data is converted to a series of slices along the vertical, or Z axis. This series of slices is transferred to the SLA machine where the physical prototype is produced. The SLA machine consists primarily of a vat of photopolymer, an elevator with a build platform, and an ultraviolet laser. The machine will then utilize the provided slice data to control power levels and movements of the machine parts. The basic build function involves the ultraviolet laser being driven across the surface of the resin to harden, or cure a layer of the liquid. Then, the platform will lower itself to a defined vertical resolution and repeat the layering process, thus stacking the original CAD data one layer on top of the previous.

Once the SLA build is complete, the parts are post processed and supports are removed.

What Makes the RJM SLA Process Different?

The basic SLA process consists of the basic steps throughout the industry. However, RJM has taken measures that help them to stand out above the rest. Using the exclusive Ultra Hi-Res SLA process, RJM can guarantee a higher quality and resolution part for our clients. When super fine detail or superior surface finish is required in an SLA part, RJM remains unmatched.
