3D Printing & Urethane Casting

3DSI provides advanced additive manufacturing and urethane casting solutions to support every stage of product development — from early concept models to production-quality parts.

With over 20 years of engineering and product development experience, we don’t just produce parts — we help you make the right decisions to achieve your desired outcome.

Whether your priority is speed, strength, surface finish, or scalability, we guide you to the most effective solution.

Engineering-Grade 3D Printing

We utilize both SLA (resin) and FDM (thermoplastic) technologies to produce high-quality prototypes and functional components.

Capabilities

• High-detail SLA printing for precision and surface quality

• FDM printing for durable, functional parts (PLA, TPU, and engineering materials)

• Layer optimization and post-processing to improve performance and finish

• Custom support strategies to reduce defects and improve part quality

What Makes Us Different

Most service bureaus print what you send.

We evaluate:

• Geometry and failure risk

• Build orientation and support strategy

• Material selection based on end-use

• Tolerance and fit requirements

This ensures parts are not just printable — but usable.

Outcome

You get parts that:

• Function as intended

• Require less rework

• Move your project forward faster

Production-Quality Parts Without Tooling Delays

Urethane casting allows us to produce high-quality, end-use parts that closely replicate injection molded plastics — without the cost and lead time of hard tooling.

Capabilities

• Silicone mold creation from SLA master patterns

• Wide range of materials (rigid, flexible, rubber-like durometers)

• Surface finishes that eliminate visible print layers

• Short-run production for testing and early market entry

When to Use Urethane Casting

• You need production-quality appearance

• You want to eliminate print layer artifacts

• You are preparing for injection molding

• You need low-volume production runs

Outcome

Parts that:

• Look and feel like final production components

• Bridge the gap between prototype and manufacturing

• Allow validation before committing to tooling

Beyond Printing — Complete Product Development Support

Most customers need more than parts.

3DSI provides a complete development pathway:

• Design & proof-of-concept development

• Product refinement and manufacturability guidance

• Short-run production for testing and validation

• Transition support into injection molding or scaled manufacturing

• Domestic and international manufacturing partnerships
