Industrial 3D Printing

For big parts, real materials, and production runs

From desktop-sized industrial FDM to large-format FDM, SLA/DLP, and DMLS, we help you get functional 3D printed parts made without guessing on process, material, or supplier fit.

  • Large-format FDM for oversized parts, tooling, patterns, fixtures, and enclosures.
  • Engineering materials for heat resistance, stiffness, toughness, and real-use performance.
  • Batch quantities from one-off prototypes to short-run production.

3D printing capabilities

From functional FDM prototypes and production aids to specialized resin, nylon, sand, and metal additive processes, Relay gives engineering teams one place to start. We review the application first, then match the part to the process that makes technical and commercial sense.

Part review before production

Start with the application, not the machine.

A process is only useful when it fits the part. Relay reviews the conditions the component has to survive, the geometry that has to print, the finish that matters, and the quantity that has to make financial sense before recommending a route.

01

Function & environment

Loads, heat, chemicals, impact, flexibility, and intended service life.

02

Geometry & scale

Build size, wall sections, support strategy, assembly, and feature access.

03

Material & finish

Mechanical performance, surface expectations, color, and post-processing.

04

Quantity & economics

One-off prototypes, repeat orders, batch layout, and production planning.

Built for work

Functional parts across the product lifecycle.

Industrial 3D printing is most valuable when it removes tooling, compresses iteration, enables difficult geometry, or makes low-volume production practical. Relay helps determine where it belongs in the job—and where it does not.

01

Functional prototypes

Test fit, motion, handling, assembly, and performance before committing to production tooling.

02

Jigs & fixtures

Build practical production aids, inspection tools, drill guides, nests, and custom workholding.

03

Tooling & patterns

Create foundry patterns, thermoforming tools, molds, masters, and large-format manufacturing aids.

04

Enclosures & housings

Produce custom covers, guards, cases, ducts, and equipment interfaces without hard tooling.

05

Oversized components

Print full-scale parts or engineered sections when conventional build volumes are not enough.

06

Short-run production

Move into repeatable batch quantities for end-use parts, replacement components, and bridge production.

A clear path to production

Send the part. Get a manufacturing answer.

No instant-quote roulette. Relay reviews the project, clarifies what matters, and coordinates the job through delivery.

  1. 01 / INPUT

    Send the files

    Share the model, quantity, use case, target date, and any critical requirements.

  2. 02 / REVIEW

    Confirm the route

    We review process, material, orientation, finishing, and any geometry that needs discussion.

  3. 03 / QUOTE

    Approve the plan

    You receive a clear scope, pricing, lead time, and assumptions before production begins.

  4. 04 / DELIVERY

    Make and deliver

    Relay coordinates production, follows the job, and gets the finished parts to your door.

Have a part that needs a better manufacturing answer?

Send the model and tell us what the part has to do. We will help narrow the process, material, and production path before you commit.
