• Enclosed FDM additive manufacturing

• In-house domestic production in New York

• Prototype and small-batch builds

• Functional orientation and print-strategy selection based on use case

We support a focused set of thermoplastics selected for functional reliability. We currently do not support aerospace products (PEEK, PEKK).

Material selection is reviewed during quote evaluation to confirm suitability for the intended application.

Our capabilities are well-suited for:

• Defense-adjacent, industry, and field-use functional parts

• Jigs, fixtures, and tooling aids

• Enclosures and protective housings

• Functional prototypes for fit, form, and use testing

• Small-scale production for advanced prototypes

One-off and low-quantity builds

• Small-batch production (typical runs under 50 units)

• Customer-provided CAD files (STL or STEP preferred)

• Review-based acceptance prior to quotation

Projects are evaluated for feasibility, orientation, material selection, and expected performance before pricing and lead time are issued. We will finish any product started.

Sentinel Fabrication maintains intentionally capabilities to ensure process control, repeatability, and predictable outcomes.

By limiting materials, methods, and project types, we reduce variability and avoid the quality degradation common in generalized or hobby-focused print services.

We are not some faceless over-seas ‘print farm’, we are an American owned company with over 6 years of experience in the 3D printing space.

These constraints allow us to deliver consistent functional results for applications where performance and reliability matter more than novelty or volume.
