The High-Resolution Solution

SLA has come a long way from its origins in the mid 1980s to becoming today’s leading solution for high-resolution prototypes and production parts.

Although SLA was a novel approach for its time, the first parts had visible lines showing individual layers and edges that were not uniform. Hand-finishing the prototypes by sanding was a common practice. As a result, the dimensions varied from part to part—and from the original designs.

Today, those challenges seem a distant memory. The most recent advances in SLA technology have dramatically increased both resolution and accuracy of the finished part. SLA machines now produce models with clearer definition and edges. Lines are less obvious, and corners and edges are more defined. Prototypes that require threads, pin holes and snap fits are more accurate.

One example is the high-resolution Viper™ si2, manufactured by 3D Systems Corporation. The machine is ideal for small, precision builds with extremely detailed parts. When it comes to high resolution on a larger scale, 3D Systems’ Viper™ Pro takes SLA to a higher level, offering speed, accuracy, surface finish and a maximum part size normally associated with CNC machining.

Major advancements have also been made in terms of materials, providing finished parts with qualities such as heat-resistance, exceptional durability and flexibility.

Another development with high-resolution SLA is its use as a rapid manufacturing option. Realizing the cost-effective benefits and fast turnaround of accurate, functional parts, many product developers place SLA orders for up to 100 parts for finished production units.
