From Pellet Development to Production Parts

Stack3d is the only manufacturer that controls the entire process, from raw material formulation to finished parts. Whether you need a custom thermoplastic blend, production-ready filament, or a large-format printed component, we handle it all in-house so you move faster and stay in control.

Full-Stack Additive Manufacturing

Integrated Material To Part Development

Most manufacturers source their materials from one supplier and their printing from another. Stack3d does both, which means your material is engineered specifically for your application, not just whatever’s available off the shelf. That translates to better part performance, fewer iterations, and faster time to production.

From material formulation to production-ready parts, our capabilities include:

  • Thermoplastic Material Development

  • Specialty Colors & Engineered Materials

  • Feedstock Manufacturing (Filament + Pellets)

  • Large Format Additive Manufacturing (LFAM)

  • Rapid Prototyping & Bridge Production

  • End-Use & Low-Volume Production Parts

  • Material & Part Characterization

3D Printing Services Built for Real-World Performance

Idea to Prototype to Production

Stack3d delivers on-demand 3D printing that moves directly from concept to functional part without unnecessary handoffs or delays. With more than 60 years of combined additive manufacturing experience, our team supports projects from early design through production-ready components.

We combine multiple manufacturing technologies, including SLS, FDM, and large-format additive manufacturing, to match the right process to each application. Whether you are developing a prototype, validating a design, or producing small-batch parts, we focus on speed, consistency, and real-world performance.

Additional Services & Capabilities

Design & Manufacturability Feedback

Support to improve part geometry, printability, and performance before production.

Material Validation & Testing

Mechanical and thermal evaluation to confirm material and part performance.

Rapid Prototyping & Bridge Production Tooling

Short-run injection molding tools and transitional manufacturing solutions for scaling beyond prototyping.

Post-Processing & Assembly Support

Finishing operations including inserts, machining, blasting, and assembly preparation for end-use parts.

Additive Manufacturing Capabilities

SLS

Selective Laser Sintering (SLS) is a powder bed fusion process used to create complex geometries and functional prototypes with high dimensional accuracy and consistent mechanical performance.

FDM

Fused Deposition Modeling (FDM) is an extrusion-based process used for durable, cost-efficient parts during early-stage development and rapid design iteration. development and rapid design iteration.

LFAM

Large-Format Additive Manufacturing (LFAM) is a pellet-based extrusion process used for large-scale functional components and production-oriented parts where throughput, size, and scalability are critical.

Custom Material Production

Production of Non-Standard Materials, Including Custom Colors

We produce thermoplastic materials tailored to application requirements, including custom color development and non-standard formulations that fall outside typical off-the-shelf material systems.

This includes adjusting material properties, integrating recycled content where appropriate, and developing consistent, repeatable color matching for functional and aesthetic requirements.

The result is application-specific feedstock designed for reliable processing and predictable performance in downstream additive manufacturing and production workflows.
