High-Detail Resin Additive

SLA & DLP 3D Printing Services

Engineering-quoted resin printing for fine features, smooth surfaces, visual prototypes, tooling, and specialized material needs.

Relay can evaluate SLA and DLP when surface quality, fine detail, transparency, casting patterns, molds, visual appearance, or specialized resin properties drive the job. These projects are handled by engineering quote so resin selection, post-curing, supports, finish, and service conditions can be reviewed before production.

Best-Fit Applications

Where this process earns its place.

High-detail prototypes

Quote around the actual geometry, quantity, service conditions, and critical requirements rather than the process name alone.

Smooth cosmetic models

Quote around the actual geometry, quantity, service conditions, and critical requirements rather than the process name alone.

Clear or translucent parts

Quote around the actual geometry, quantity, service conditions, and critical requirements rather than the process name alone.

Molds and masters

Quote around the actual geometry, quantity, service conditions, and critical requirements rather than the process name alone.

Small precise features

Quote around the actual geometry, quantity, service conditions, and critical requirements rather than the process name alone.

Specialized resin applications

Quote around the actual geometry, quantity, service conditions, and critical requirements rather than the process name alone.

Materials & Process Fit

Material selection follows the application.

Available resin families vary by application and may include rigid, tough, clear, flexible, high-temperature, castable, and other specialty formulations.

What to include in the RFQ

CAD, quantity, application, critical dimensions or interfaces, finish expectations, material requirements, environment, target date, and any downstream assembly or inspection needs.

Engineering Review

Function, geometry, material, finish, and quantity drive the route.

Resin properties vary significantly. UV exposure, heat, brittleness, post-curing, support marks, dimensional stability, and long-term service conditions should be reviewed before selecting a grade.

Relay's role is to identify the process that makes technical and commercial sense, not to force a job into whichever machine appears first on a service list.

Buyer Questions

What engineers usually need to know.

When should I use SLA or DLP instead of FDM?

Use resin printing when fine detail, smoother surfaces, small features, transparent materials, or application-specific resin properties are more important than FDM economics or thermoplastic behavior.

Can SLA or DLP parts be functional?

Yes, depending on the resin and service conditions. Functional use should be evaluated around load, temperature, UV exposure, impact, and expected lifetime.

Does Relay offer instant SLA pricing?

SLA and DLP are currently handled by engineering quote rather than the instant FDM estimator.
