SLS & MJF 3D Printing Services
Engineering-quoted nylon parts for complex geometry, functional assemblies, and repeat production.
Relay can evaluate SLS and MJF when nylon powder-bed printing is a better fit than FDM. These processes are useful for complex parts, support-free geometry, nested batch production, functional prototypes, and low-volume nylon components. Jobs are reviewed and sourced by engineering quote rather than forced through the instant FDM estimator.
Where this process earns its place.
Nylon functional parts
Quote around the actual geometry, quantity, service conditions, and critical requirements rather than the process name alone.
Complex support-free geometry
Quote around the actual geometry, quantity, service conditions, and critical requirements rather than the process name alone.
Nested batch production
Quote around the actual geometry, quantity, service conditions, and critical requirements rather than the process name alone.
Snap fits and living features
Quote around the actual geometry, quantity, service conditions, and critical requirements rather than the process name alone.
Short-run production
Quote around the actual geometry, quantity, service conditions, and critical requirements rather than the process name alone.
Assemblies with internal detail
Quote around the actual geometry, quantity, service conditions, and critical requirements rather than the process name alone.
Material selection follows the application.
Common options include PA12 nylon and other process-specific polymer powders depending on mechanical, cosmetic, and production requirements.
CAD, quantity, application, critical dimensions or interfaces, finish expectations, material requirements, environment, target date, and any downstream assembly or inspection needs.
Function, geometry, material, finish, and quantity drive the route.
Surface texture, dimensional expectations, wall thickness, powder escape, post-processing, color, sealing, quantity, and vendor/process selection all affect the final manufacturing route.
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.
What engineers usually need to know.
When should I choose SLS or MJF instead of FDM?
Consider powder-bed printing when support-free geometry, nylon performance, nested batch economics, or more uniform mechanical behavior matter more than the lower-cost simplicity of FDM.
Is SLS or MJF good for production parts?
Yes. Both are commonly used for low-volume and repeat production when the geometry, material, finish, and economics fit the process.
Can Relay help choose between SLS and MJF?
Yes. Send the CAD, quantity, application, finish expectations, critical dimensions, and target date. Relay can evaluate which route makes more sense.
Send the CAD and the requirements that actually matter.
This process is handled by engineering quote so the manufacturing route can be reviewed before pricing is finalized.
